WARRANTY
Limited One-Year Non Wearing Parts Warranty
Synesso, Inc and/or your Distributor warrants to the original purchaser that Synesso espresso machines are free from
defects in materials and workmanship under normal use and service for the period commencing upon the date of
shipping and continuing for 12 months from the original date of shipment. Synesso will make a good faith effort for prompt
correction or other adjustment with respect to any non-wearing part that proves to be defective within the limited warranty
period. This Limited Warranty is conditional upon proper use of the machine by the purchaser.
This Limited Warranty does not cover defects or damage resulting from: accident, misuse, abuse, shipping damage,
neglect, unusual physical, electrical or electromechanical stress, unauthorized customer modifications or improper water
filtration.
Proper water filtration and regular filter changes are a requirement to keep your factory warranty valid and your machine
functioning properly. It is highly recommended that you contact a professional water filtration specialist in your area and
have your water tested to determine the proper filtration system. It is important to note that many municipalities change
their water sources throughout the year, so additional water tests may become necessary.
Water Standards to keep your warranty valid:
Total Dissolved Solids (TDS)
30 to 200 ppm (parts per million)
Total Hardness - in ppm
Less than 85 ppm
Total Hardness – in grains
3 to 5 grains (divide ppm by 17.1 to get grains)
pH
6.5 to 7.9 pH
Chloride
0 ppm – Chloride can damage the boilers
Total Alkalinity
Less than 100 ppm
Chlorine
0 ppm
Iron
0 ppm
In Synesso’s experience, Everpure Claris and Cirqua formulator systems can
produce a result that can damage the Synesso boilers. Use of either of these
systems is discouraged, and will void the water-related parts of the machine
warranty.
Any part which is determined to be defective in materials or workmanship should be returned to Synesso or to an
authorized service location, shipping costs prepaid, as Synesso designates. Synesso may repair or replace the product
or part with new or factory refurbished equipment at Synesso’s sole discretion. If the product or part is determined to be
defective and in compliance with the Limited Warranty conditions, the replacement part or product will be returned to the
purchaser with shipping prepaid **.
Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of products for
certain purposes, which may vary from area to area. While Synesso attempts to assure that its products comply with such
codes, it cannot guarantee compliance and cannot be responsible for how the product is used or installed.
Synesso’s liability is limited to the purchase price of the product and shall not be held liable for damages that extend
beyond the product itself. Synesso’s liability of consequential, incidental damages, indirect or direct damages for personal
injury, inability to properly use this product, loss of business profits or interruption to business is expressly disclaimed.
NOTE regarding equipment sold or residing outside the United States: purchaser maybe required to pay for the shipping
and associated costs for warranty parts, repairs and services. Please contact your local distributor to resolve the issue
regionally, if possible.

To maintain the 1 year warranty, an authorized or certified espresso service representative
must perform the installation of this espresso machine.
Site Preparation - See Diagram p.7
The machine must be placed on a level horizontal surface that can be easily cleaned and is capable
of sustaining a minimum of 300 lbs.
The counter top requires a depth of 28”, which provides a minimum clearance of 1” behind and 3” in
front of the machine.
Make a 2 ½” minimum diameter hole through the counter top located 4” from the rear and 7” from the
right side of the machine. The hoses, drain tube, and electrical lines will all pass through this hole.
A 3/8” min. diameter cold water supply line from the filter with a shut off valve is required within 5’ of
the machine. The valve should be easily accessed for machine service.
The machine supply hose and pump fittings are 3/8” tube compression fittings.
A proper water filtration or softening system must be installed on the incoming water supply. Water
treatment requirements will vary, and it is important to use a system designed to match the needs
of your specific area. Water filtration systems require periodic maintenance, including cartridge or
filter replacement. Proper filtration and service is vital to the function of the machine and the quality
of the espresso served. Follow the instructions provided by your water treatment system for proper
installation.
Note: Improper water filtration can result in severe damage to the machine including scale deposits
and corrosion. DAMAGE CAUSED BY IMPROPER WATER TREATMENT WILL NOT BE COVERED
BY THE MACHINE WARRANTY. See page 5.
There must be adequate room under the counter to locate each motor and pump. The pumps must be
easily accessible for adjustment and motors must have a minimum of 3” clearance on all sides for air
flow.
A floor drain or sink must be available. The best location is directly under the machine. The 3/4” drain
hose should descend as vertically as possible for optimal drainage. An air gap is required between
the end of the drain hose and the highest water position of a clogged drain. This is to prevent the
possibility of drain water backing up into the machine.

This equipment must be installed to comply with the applicable federal, state or local plumbing codes.
WATER TREATMENT IS REQUIRED TO PRESERVE THE FULL MACHINE WARRANTY. Please
insure that the incoming water complies with the warranty requirements listed on page 5.
Using the provided stainless steel braided hose, connect the pump to the shutoff valve on the filtered,
cold water line. Fittings on the hoses and pumps are 3/8” tube compression. Thread sealant or Teflon
tape is not necessary. Make connections snug, but do not over tighten.
Turn incoming water ON and check for leaks.
Synesso machines require a minimum of 50 PSI (3.5 bar) of line pressure at 30gal (120L) per hour to
have the auto-fill system for the steam tank function properly. Please ensure that the incoming water
meets this requirement or contact Synesso for alternative methods of boosting water pressure.
NOTE: Synesso sells a “Euro-hose” adaptor hose and fitting (part number is 1.5020) which converts
from a 3/8” tube fitting to a pipe fitting, suitable for most non-US plumbing). Please refer to the picture
below to identify the differences between the standard and Euro-styles fittings and hoses.

Make sure that the red electronics switch and the heating element breaker on the front of the
electrical box are in the OFF position, then plug the power cord into the receptacle.
OPTIONAL: If recovery time is slow, install an In-Line Buck-Boost transformer to increase voltage
below 208v to optimize machine recovery time. Buck-boost transformers come in different sizes.
Please choose the appropriate one for your machine if required. 1 and 2 Group Machines require a
1.0 KVA transformer, 3 Group Machines require a 1.5 KVA transformer.
SPECIAL ELECTRICAL INFORMATION FOR EMC-COMPLIANT MACHINES
(C-TICK FOR AUSTRALIA, CE FOR EUROPE AND OTHER LOCATIONS)
To comply with EMC (Electromagnetic Compatibility) regulations, Synesso is required to install a
capacitor in the electronics box across the main power IN. To avoid an electric shock from the
charge held in the capacitor, unplug the cord, taking care to NOT touch the metal prongs on
the plug end. Turn the electronics ON/OFF red rocker switch to the ON position and wait a few
seconds until the red switch “goes dark.” At that point, the electrical charge has dissipated.
Synesso Owner’s Manual

The Hydra is a machine model with a pump and motor for each group head. This includes changes
in internal plumbing and wiring to accommodate separate and distinct pressures in each brew group.
In contrast, a Cyncra or Sabre has a single pump and motor for the entire machine. Having individual
pumps and motors allows the operator to set a separate brewing pressure per group head, and each
group functions independently without affecting the pressure at the other groups.
Hydras can be built as fully manual machines (multiple manual group heads), fully volumetric (all
group heads have programmable keypads), or a mixture of group heads to match your requirements.
Hydras with mixed group head configurations are referred to as Hybrids.
Hydra Installation requirements:
Electrical:
The Hydra package has a slightly greater amp draw than the single pump machines; please note the
max amp draws and plan your electrical installation accordingly. See table on page 9.
Each pump motor has a distinct color association, which is indicated throughout the machine by
colored wires and zip ties. The colors are as follows:
Group 1: Grey
Group 2: Purple
Group 3: Brown
Water inlet for the steam tank: Pink
Wherever these colors are seen, it is critical for proper functioning that they are matched up correctly
(grey to grey, etc.) for both electrical and plumbing systems.
Plumbing:
Hydra packages require one incoming water source like single pump machines. The water passes
through a manifold (commonly part of the line pressure regulator) and is distributed to each pump.
Once again, follow the color coding for proper installation of the hoses from the output of each pump
to the machine.

HYDRA / HYBRID
Hydra Bypass Installation and Setup
Pump cord installation: Insert the color coded pump cable into the opening of the matching bypass
box and attach the wires to the terminal as shown in the picture above: Green wires stacked on the
ground bolt, white to white/red, black to black/blue, connect the bullet connectors.
Pressure regulator: Used to achieve the stage 1 low pressure pre-infusion. It is set and tested at 50
psi in the Synesso factory. This pressure setting can be lowered if desired, but 50psi is the maximum
output pressure. To adjust the pressure regulator, first loosen the nut on the threaded post, then turn
the post counter-clockwise to decrease pressure.
Pump Bypass: First, set the pump and regulator to the desired pressures.
Manual group: Turn the associated brew group actuator to brew (2nd)
position, then back to the first position.
Volumetric group: set stage 1 time and bypass percent to zero. Press the
pitcher button.
The pin valve on the pump may then be adjusted until the brew gauge indicates the desired pressure. 7 bar is our factory setting. Adjust to taste.
The Stage 1 (Pre-infusion) time and Stage 2
(Bypass) time are set on the Temperature Control
screen of the display by following the directions
on page 17. Stage 1 time is set to 7 seconds and
Stage 2 is set to 3 seconds at the factory. Adjust to
taste.
Once these settings are in place, you will be able to taste the effects of four stage pressure ramping applied to each shot. Start the shot to begin the Stage 1 pre-infuse timer. In this stage, low pressure water will saturate the puck, swelling it to reduce channeling. After the stage 1 time has elapsed,
stage 2 bypass will begin. In this stage, the bypass system will help create a slow rise in water pressure by diverting high pressure water away from the brew group. After the stage 2 time has ended,
the bypass will close and stage 3, full pump pressure (9 bar) will begin. Stage 4 is a return to bypass pressure. In the case of manual groups, entering stage 4 is determined by the operator and is
achieved by moving the group top actuator back to position 1. Volumetric groups can be programmed
to automatically begin stage 4 at a set percentage of the shot as described on page 18.

To fill the machine, connect the water lines, set the drain hose and turn the water ON.
Switch the red electronics On/Off switch to ON. This activates the machine’s water auto-fill
feature for the steam tank and the electronics, but NOT the heating elements.
The water level sight glass for the steam tank is located on the right side of the machine. As
the tank fills, the water level will rise in the sight glass and will automatically stop when the
preset level is reached.
Bleed the group heads of air:
Manual machines: Turn each group head handle left into the BREW position, (see pictures
below) allow the group to run until there is a steady flow of water. Return the group head to the
OFF position.
Volumetric machines: Activate the pitcher button on the right side of the keypad. Once the
water flows in a steady stream, press the pitcher button again to stop the water.
Wait until the steam tank has stopped filling and the level in the sight glass reads at
least ½ full. Turn the heating element breaker to the ON or (1) position. All the heating
elements (brew and steam) are now activated.
To adjust the pump pressure, activate the pump by turning the brew group to the BREW
position. On volumetric machines, activate the pump with the pitcher button.
Locate and read the pump pressure / brew gauge to the right side of the machine (To the right
of each group on a Hydra.)
Set the pump pressure to 9 Bar:
Locate the pump adjusting screw on the right side of the brass pump housing.
Loosen the lock nut and turn the screw with a screwdriver
•
Clockwise to INCREASE pressure
•
Counterclockwise to DECREASE pressure
Once the desired pressure is reached, retighten the lock nut.
Please allow at least 30 minutes of “warm up” time before using your Synesso espresso
machine to brew shots or steam milk. The steam gauge (the left hand gauge) should read a
minimum of 1.1 Bar.

For best results, use fresh coffee. Ground coffee should be brewed as soon as possible after
grinding.
Select the correct spout and basket configuration. Single, double and bottomless portafilters
are available through Synesso. The single spout portafilter is used with a single (7g) basket to
brew a single shot. The double spouted or bottomless portafilters can be used with double
(14g) or triple (18g or 21g) baskets to brew triple, double, or 2 single shots of espresso.
Fill the portafilter basket just above level and wipe off the excess.
Press straight down evenly on top of the grounds with the tamper.
NOTE: When not in use, keep the portafilter engaged in the group head to keep it warm.

Preinfuse the coffee puck by turning the brew group clockwise to the center position. This
allows line pressure to saturate the coffee.
NOTE: If a stage 1 or 2 time is set on the display, they will begin automatically on moving to the brew
position, so the preinfusion position should be skipped.
7.
When a drip shows at the spout (or on the basket if bottomless), Turn the group cap clockwise
again to the brew position. This engages the pump.
8.
When the stream of coffee turns from brown to “blonde”, end the shot by returning the group
cap to the far right position. Machines using pump bypass hardware may move back to the
preinfuse (center) position just before the shot blonds to extend the extraction and delay
blonding.
(Volumetric)
6.
Press one of the first 4 buttons on the button pad.
7.
If stage 1 or 2 timers have been set, the machine will execute these times automatically, then
move into the brew stage. Machines equipped with pump bypass systems can use an
automatic bypass at the end of the shot. See page 18.
8.
The shot will automatically end once the set volume of water has been dispensed.
Milk Steaming
1.
Fill the pitcher halfway with fresh, cold milk. Smaller pitchers are recommended for drink sizes
less than 10oz. Steamed, unused milk should be discarded.
2.
Condensation can collect inside the wands. Carefully blow the wands clear before steam.
3.
Insert the tip of the steam wand deep into the milk pitcher. This will prevent milk from
splashing once the steam is turned on.
4.
Open the steam valve by pulling the handle towards you.
5.
Place one hand on the side of the steam pitcher to feel the rising temperature of the milk.
6.
As the milk agitates and heats, lower the pitcher to keep the tip of the steam wand closer to
the surface. Allow the steam jets to push some air beneath the surface, then raise the pitcher
to lower the tip of the wand deeper into the milk. This will continue the heating process and
minimize further foaming. Do not touch the steam wand to the bottom of the milk pitcher; this
can create an inaccurate temperature measurement.
7.
Heat milk to approximately 150F to 170F (65°C to 76°C). If you are using your hand to help
determine the temperature, it will feel about as hot as you can stand without burning yourself.
Milk thermometers are also an excellent way to determine the temperature of the milk.
Caution: Do not overheat the milk and scald it. Scalded milk should not be used.
8.
Remove the wand from the milk, purge, and wipe clean immediately after each use.
NOTE: Although Synesso steam wands are made with a proprietary double-walled process that helps
to keep the outer wall cooler, the tip and base can become very hot and caution must be used.
NOTE: Whole Milk, 2%, 1%, Non-Fat, Soy Milk, Rice Milk and other milk type products may require a
different technique to foam properly. In general, the higher the fat content, the easier it is to achieve
consistent foam.

O P E R A T I O N
OPERATION
The following options are available on Synesso machines. If you have one or more of these options,
please follow the instructions below. With the exception of the cash valve and in-line pressure
regulator, these options are not available as after-market parts and must be installed during the
manufacturing process.
LED Shot Timers
Synesso offers LED shot timers which display how long water
has flowed through the group head. The timer is located above its
associated group head and the timer starts when the brew valve
is opened. The total run time of the last shot is displayed until the
next shot is started, at which point the timer resets to 0 and starts
counting again.
PRESSURE REGULATION DEVICES
Pump Bypass Systems (*Required for 4-stage Pressure Ramping)
Pump bypass systems are valves attached to the pump output which allow a set pressure reduction
during the shot. See Pages 17 and 18 for information on how to set and control the pump bypass
systems if this option is present on your machine.
In-line Pressure Regulator (*Required for 4-stage Pressure Ramping)
This regulator is a device installed on the incoming water line before the pump. It reduces high
incoming water pressure to a desirable level (around 50psi). This device is useful in high fluctuation
areas where there is variable water use throughout the day (i.e. hotels, apartment buildings). This is
easily adjusted by watching the brew gauge while in the pre-infuse position, then turning the handle
on the valve clockwise to increase pressure and counter-clockwise to decrease pressure.
Cash Valve
A cash valve is an option for single pump/motor, multi-group machines. It is installed on the pump
head and functions as a larger pressure adjustment tool, similar in function to the standard hex nut
adjuster on the pump head. It can accommodate and control greater variance in water fluctuation
than the standard pump adjuster, and is a good tool for situations in which large water fluctuations
are seen. Adjust the pump pressure above 10 bar using the adjustable hex nut; then adjust the cash
valve to your desired pressure (approximately 9 bar).

Error codes are
displayed here
In an effort to prevent damage to machines and to help operators troubleshoot issues, Synesso has
engineered several safeguards into the programming. These codes will help users identify operational
issues with the machine, as well as automatically prevent greater problems from occurring. By
understanding these codes, operators can remedy issues more quickly.
Error code key
BR – Brew System Codes
BV – Brew Valve has been on for 5 minutes. See page 30.
Valve will be disabled until group is turned off.
OT – Over Temperature. (220F) See page 30.
UT – Group reads under 180F for 1 minute while trying to heat (Under Temp.)
PR – Pump Relay coil has been on for 5 minutes.
Relay will be disabled until group is turned off.
BP – Bypass Valve has been held on for 5 minutes.
Valve will be disabled until group is turned off.
01, 02, or 03 – Indicate which brew group is reporting an error.
ST – Steam System Codes
LW – Low Water probe is not in contact with water (an audible alarm will also sound)
FP – Fill Probe is not in contact with water for 1 minute. See page 31.
FV – Fill Valve has been held on for 5 minutes.
Valve will be disabled until machine is turned off. See page 31.
OT – Over Temperature (270F)
01 – All Steam System Codes end in 01
VM – Volumetric System Codes
UF – Unexpected flow while group is off.
01, 02, or 03 – Indicate which flow meter is reporting an error.
Example:
After brewing a shot, group 2 was left in the brew position. After 5 minutes, the machine will register
a BRBV02 and a BRPR02 error; which translate to “Brew System, Brew Valve Group 2” and “Brew
System, Pump Relay is timed out, Group 2.” At this time the machine will automatically shut off both
the brew valve and the pump relay to ensure they will not be damaged. They will remain off until the
group is returned to the off (far right) position, which allows the group to return to normal operation.

This section contains instructions for programming the volumetric dosing on Sabre machines and
Hybrid machines with volumetric group heads. Basic machine programming is found on page 13.
Pitcher / continuous
flow button
Shot buttons
To enter programming mode, press and hold any 2 shot buttons. After 3 seconds, the indicators
for each button will illuminate. At this point, you can press the continuous flow (or pitcher) button
on one or more groups to exclude that specific group from programming. This will turn off the
upper indicators on the deselected group. A red indicator will remain lit on the deselected group’s
continuous flow button. Pressing this button again will exit the programming mode. If a group has
been deselected in error, you must exit and reenter programming mode to re-select the group for
programming.
While in programming mode, press any shot button with a lit indicator to begin a shot. As the shot
flows, the indicator at each button receiving a program will blink. Once the desired volume has been
reached, press the same shot button a second time to end the shot. The indicator light(s) will turn
off. You may now program another button or exit the programming mode. If an error has been made,
you may reprogram a button without leaving programming mode. Pressing a previously programmed
button overrides the original program.
To exit the programming mode, press any continuous flow button on a deactivated group. As noted
above, pressing a continuous flow button on an active group will deactivate it. When you exit
programming mode, all lit indicators will turn off.
Notes:
• The continuous flow / pitcher button cannot be programmed. During normal operation, pressing
the pitcher button will stop a currently flowing shot, or start a continuous flow of water from the
group.
• Any stage 1 or 2 times (see Programming, page 17) set up prior to entering volumetric
programming mode will be active during programming. Water dispensed during stage 1 and 2
counts toward total shot volume.
• Shot timers, if present, are not active during volumetric programming. The timers return to normal
function once the machine leaves programming mode.
Low Flow Error:
• If a shot button is pressed but flow is not detected by the flow meters, the two indicators on the
pitcher button will light and flash. If inadequate flow persists for 30 more seconds, the brew valve
will close, cancelling the shot. The lights will continue to flash and the group cannot be used until
the low flow error has been acknowledged by pressing the pitcher button. The most common
reason for this error will be grind/tamp mistakes, but the incoming water may be restricted. If this
error occurs frequently, please check the incoming water lines.

MAINTENANCE
Proper and regularly scheduled cleaning and maintenance procedures are CRITICAL for trouble-free
and optimum quality performance from your espresso machine.
Back-Flushing
This process forces water through the inlet tube and drain system. This should be performed on
EACH brew group daily. On the current generation of Synesso machines, back-flushing can be
automated. See page 18.
To back-flush manually:
1.
Replace the filter basket with the ‘blind’ basket, which has no filter holes.
2.
Engage the portafilter, turn the head to the BREW position for 10 seconds. Then turn the group
off again for 3 seconds. Repeat several times.
3.
When using an approved espresso industry detergent during back-flushing, follow the
manufacturer’s instructions. It is extremely important to thoroughly rinse the blind filter basket
and repeat back flushing several times with clean water to clear the system of any detergent
residue. Failure to rinse can cause valve problems and bad flavor.
NOTE: NEVER remove the screen and screw when backflushing. Remove and clean them after
backflushing is complete. Do not forget to reinstall.
General machine cleaning
1.
2.
3.
Clean the surface of the machine using a soft damp cloth. Avoid using abrasive cleaners or
cleansing pads. Take extra care on the mirror finish stainless steel surfaces. A “microfiber” towel is recommended to avoid scratches.
Make sure the steam wands and tips are free of milk build-up. It is always best to clean the
steam wand and tip after each use. Approved espresso industry cleaners can be used to
dissolve milk build-up. Tips can be removed to soak.
The drip tray, drip tray grates, and portafilters should be removed and cleaned every day. If you
clean the portafilters in the dishwasher, first remove the filter baskets and springs before
washing.
Synesso Owner’s Manual
24
Daily
1.
Back flush each brew group without detergent throughout the day.
2.
Back flush with an espresso industry approved detergent during the final cleaning of the night
(or after a busy period), and then again without detergent to rinse.
2.
Wipe down the entire machine with a soft cloth.
3.
Remove portafilters, baskets and springs, drip tray and grates and clean thoroughly. These
items are all dishwasher safe.
4.
Slowly pour a pitcher of hot water down the drain to clear grounds debris and prevent
blockage.
Weekly
1.
Soak portafilters and the removed filter baskets in an approved espresso industry detergent
and water solution overnight. Rinse thoroughly before reassembling and using your
portafilters.
2.
Carefully remove screens from each brew group using a short handled screwdriver and soak
overnight in a similar solution as the portafilters.
3.
Rinse screens thoroughly before installing and using. Make sure you install the screens
before brewing any shots of espresso. Failure to do so may plug the drain lines
with coffee grounds.
Monthly
1.
Check your water filtration system and make sure the cartridges and filters are changed as
needed. In areas of high mineral content, hard water, high particulate count or in very
busy locations, the filtration systems will need to be checked more often.
Quarterly
1.
Change portafilter gaskets and closely inspect diffuser screens and filter baskets, If these
items are showing wear, please replace them as soon as possible. Change these items if they
show damage or overuse.
2.
Briefly inspect the machine for leaks or potential issues. Contact Synesso or your local
distributor or service agent to order parts and/or request service.
Synesso recommends that you contact your distributor or service agent for periodic maintenance.
The frequency of maintenance visits will depend on a variety of factors including how much use the
machine receives, but at least one preventative maintenance visit a year is required. During this
yearly service, all body panels must be removed and all connections both electrical and hydraulic
must be inspected. Small problems can become large if not caught early.

TROUBLESHOOTING
This is a troubleshooting guide for some of the common issues that operators might encounter when
using their machine. For more detailed assistance with technical issues, contact your distributor or
local service agent.
The machine may be reset by powering off for 10 seconds.
Brewing problems
The shot is pouring too slowly:
• Tamp pressure was too firm
• Too much coffee is in the basket
• The grind is too fine
• Diffusion screens are clogged; clean or replace
• Pump pressure is too low. Ensure that it is set between 8-9.5 bar
• Brew jet is clogged; when operating properly, 60ml should flow out within 8 seconds
The shot is pouring too quickly:
• Tamp pressure is too light
• Not enough coffee in the basket
• Grind is too coarse
• Portafilter baskets are worn or cracked; replace
• Brew temperature is too cold
Crema is thin with large bubbles and tastes astringent:
• Coffee is old
• Grinder burrs are dull
• Brew temperature may be set too low
Diffuser screen is loose:
• This is most likely caused by over filling the portafilter basket with coffee. This causes the
expanding coffee puck to push against the diffuser and bend the screen-to-screw contact point
away from the screw.
No pump pressure when water flows from the group:
• Check position of group head: ensure that it is in the brew position.
• Pump relay may have failed
• Stage 1 time may be set to run too long.
The pump comes on, gauge reads full pressure, but no water comes out:
• Diffuser screen/screw, or brew jet is clogged (can be caused by soap residue not fully flushed after
cleaning).
• The water filter is clogged and needs changing
• Brew solenoid has been sealed shut by dried soap or has failed.
Synesso Owner’s Manual
26
Brew Gauge
Brew Pressure gauge needle value changes often:
• This is normal. The lowest number (usually 3-5 bar) reflects the incoming line pressure. When
brewing the needle reflects brew pressure (8.5-9 bar). When the brew tanks heat, the water
expands and the expansion valve relieves the pressure at 11 or 12 Bar.
Brew Pressure is Low:
• Check pump to make sure pressure is properly set
• Water supply hose to the pump is kinked
• Water filter is plugged. Check and replace if necessary
Pump Motor Runs; No Brew Pressure:
• Failed pump, needs to be replaced
• Brew Solenoid is stuck (can be caused by soap residue not fully flushed after cleaning).
• Brew Solenoid has failed
• The line between the pump and the water supply has collapsed or is kinked
• Hose to the pump is kinked
• Water filter is plugged. Check and replace if necessary
• Water supply is inadequate
Readout for Brew Water Temperature Varies by a Few Degrees:
• The control must “see” the increment just above the set point before it sends a signal to turn off
the heating element. This will allow the electronics to show a reading just above the set point. The
energy from the heating element and the tube for the preheated incoming water are within 1” or
25mm from the location of the temperature sensing probe in the coffee tank. The water pick up
tube for brew water is at the top of the brew group and is in the most temperature stable water in
the tank. Meaning, the readout can show a temperature of a few degrees above your set point,
and may fluctuate due to the heat from the element or heat exchanger, but your brew water is
actually at the set point.
Electronics
All zones read LOW:
• Check to make sure the element breaker is ON (element switch is to the left). Zones will read low
until the temperature in that zone reaches 175° F. Please allow 20-30 minutes to heat up initially.

TROUBLESHOOTING
Steam Wand
Drip at the Steam Wand Tip:
• Steam valve seal is worn. Replace by installing steam valve rebuilt kit.
• Steam valve is filled with milk residue. Disassemble steam valve and clean.
Wand is Hard to Move or Sticky:
• Remove wand at the nut, clean and lubricate moving parts with food grade grease
Steam
Sudden loss of steam pressure:
• Commonly caused from drawing large amounts of hot water while steaming milk. Allow the
machine time to recover pressure. Check temperature settings on Steam 1 and 2 to make sure
they are high enough for your application. Watch the steam gauge when the pressure drops; allow
the heating elements to heat the incoming cold water. When it reads above 1.1 bar, hot water and
steam may be dispensed again.
• Check the programming keypad to make sure all temperatures, especially in the steam tank, are
close to their set points.
• Check the element breaker on the electronics box to make sure the heating elements are ON
(element switch is to the left).
Steam Tank is overfilling:
• Water is too soft; this occasionally happens with reverse osmosis water filtration systems. The
water level (auto fill) probe needs a minimum mineral content in order to detect water.
• Debris caught in the water control valve or worn out valve.
• Calcium deposits on the fill probe are preventing the probe from detecting the water level.
Steam Valve Stem Seals Leak:
• Replace O-rings. Purchase Rebuild Kit
The Sight Glass shows over or under filled steam tank
• Machine is not level. Check to make sure the surface that holds the machine is level. Slightly
adjust leg height to level the machine.
• Water level is too high; use the hot water spout to drain water from the steam tank. Continue
releasing hot water until the autofill system activates. Once autofill stops, recheck the water level.
• Debris is stuck in the water control fill valve.
