C DESCRIPTION OF THE APPLIANCE
The main functions of the machine, and its relative parts, are described below, with a view
to ensuring its maximum performance.
gb
1 COFFEE DISPENSING (K-Kwts-S-M-C-B)
Independent dispensing groups with predosed or manual selections.
Filterholders for one or two cups.
2 DISPENSING OF HOT WATER AND STEAM (K-Kwts-S-M-C-B)
The machine has one or two steam wands and a hot water dispenser which allows the use
of large milk or water containers thus guaranteeing good general ergonomics.
3 ELIMINATION OF CALCIUM AND MAGNESIUM SALTS FROM THE WATER
(K-S-M-C-B)
This enables the elimination of scale deposits in the machine thanks to a water softener
that softens the water, eliminating the calcium and magnesium salts contained in it.
The water softener is not incorporated in the machine and has an independent manual
or automatic function.
4 ELIMINATION OF CALCIUM AND MAGNESIUM SALTS FROM THE WATER
(Kwts)
This enables scale deposits to be removed from the machine.
It consists of an ion exchange resin water softener, completely and automatically managed
by the machine.
5 AUTOMATIC REGENERATION OF THE WATER SOFTENER RESINS (Kwts)
When the resins in the water softener are used up, all the operator has to do, on receiving
the automatic prompt from the machine, is to load the salt.
During regeneration, the system automatically excludes the water treatment circuit from
the machine water supply, allowing the machine to operate without it.
6 ELIMINATION OF CHLORINE AND ORGANIC COMPOUNDS FROM THE
WATER (Kwts)
Removes the bad taste and deposits caused by the Chlorine and eliminates bacteria, making
the water purer.
It consists of a silver-loaded activated carbon cartridge fitted inside the machine,
at the water supply inlet.
The system signals the exhaustion of the cartridge in relation to the volume of water that
it has treated and excludes it automatically from the machine water supply circuit, allowing
the machine to continue operating without it.
7 CONTROL OF WATER LEVEL IN THE BOILER (K-Kwts-S-M-C-B)
This is done by means of a level probe which controls the water level in the boiler,
topping it up automatically when required.
56
Downloaded from www.Manualslib.com manuals search engine
8 CONTROL OF WATER TEMPERATURE IN THE BOILER (K-Kwts-S-M-C-B)
gb
This keeps the temperature of the coffees constant as opposed to the temperature
and the pressure of the steam.
Consequently, it also controls the pressure in the boiler.
9 STABILIZING THE BREWING TEMPERATURE (K-Kwts-S-M-C-B)
Each dispensing group has a heating circuit for brewing water that functions with
a heat exchanger.
This circuit ensures that the dispensing group remains at a constant and optimal temperature
even when it is not being used thanks to the effect of the natural circulation of hot water
flowing through the circuit itself.
10 MEASURING THE BREWING PRESSURE (K-S-M-C-B)
This enables the manual regulation of pump pressure during coffee dispensing.
The pressure is displayed on the gauge clearly visible in the working area.
On the K model, the gauge is fitted inside the machine.
11 MEASURING THE BREWING PRESSURE (Kwts)
Through the reading of the display, this enables the manual regulation of pump pressure
during coffee dispensing.
12 MEASURING THE WATER SUPPLY PRESSURE (Kwts)
Enables automatic protection in the event of a water supply stoppage.
13 PROTECTION OF THE HEATING ELEMENTS (K-Kwts-S-M-C-B)
This consists of a safety level probe that triggers the cutting off of power to
the heating elements.
Resetting takes place through Basic Programming.
See chapter “G – USE”.
14 PROTECTION FROM OVERHEATING (K-Kwts-S-M-C-B)
In each of following cases:

Place the cups on the upper cup tray and remove them when they are needed, according to
a rotation system that allows them sufficient time to heat.
Do not place cloths between the tray and the cups.
Do not cover the cups with cloths or other materials
.
9 WARMING THE CUPS (K-Kwts)
Press the button marked with the symbol
located to the side of the main switch.
The heating goes off, also automatically, when the temperature of the cup heating tray
exceeds the maximum value set.
It comes back on automatically when the temperature drops below the minimum value set.
10 MAKING THE COFFEE (K-Kwts-S-M-C-B)
1) Detach the filterholder from the dispensing group by turning it towards the left,
and fill the filter with the dose of ground coffee.
2) Level it out and press it with the tamper. Ensure that no grounds are left on the edges
of the filter. This will ensure a better seal and prolong the life of the filterholder gasket.
3) Attach the filterholder to the dispensing group, turning it firmly towards the right.
4) Place the cups underneath the spouts and start dispensing.
5) When dispensing is over, leave the filterholder attached to the group until further
dispensing is required.
6) When a new coffee is required, discharge the coffee cake into the waste drawer without
striking too hard so as not to damage the edge of the filter.
In order to obtain a good Italian-style espresso coffee, grinding is of fundamental importance.
The espresso must be dispensed in approx. 25 seconds and must have, on average,
a volume equivalent to approx. 25 cc (single short button).
If the grinding is too coarse, it will produce an overheated espresso with no froth.
If the grinding is too fine, it will produce an espresso with little froth.
Good quality coffee is obtained by using a fresh, evenly ground blend (only obtainable if the
coffee grinder has sharp blades) used in the correct quantities (approx. 7 grams per dose).
It is important to have coffee been freshly ground because otherwise it rapidly loses its aroma
and the fatty substances contained in it go rancid; it is therefore advisable to finish it before
the end of the day and the closing of the bar.
Warm cups contribute considerably to maintaining the quality of the espresso.
11 MAKING CAPPUCCINO, MILK AND OTHER HOT DRINKS (K-Kwts-S-M-C-B)
In order to froth up the milk, which is essential for making cappuccino, half-fill a tall,
narrow container with milk and proceed as follows:
1) Briefly open the steam valve so as to remove any water condensation that might
have collected.
2) Place the container with the milk underneath the steam wand so that the spray nozzle
touches the bottom. Open the steam valve and bring the milk to the desired temperature.
3) Lower the container so that the spray nozzle rises almost to the surface of the milk and,
from this position, raise and lower the container repeatedly so that the spray nozzle
enters and surfaces from the milk alternately. Continue until the milk has frothed up.
To make the cappuccino add hot espresso coffee to the hot frothy milk.

H MAINTENANCE AND CLEANING
1 DAILY CLEANING OF DISPENSING GROUPS AND FILTERHOLDERS
(K-Kwts-S-M-C-B)
gb
Each evening or at least once a day, clean the group shower and the filterholder gaskets
with a cloth or a sponge. Rinse the filters and filterholders in boiling water in order to remove
the fatty deposits of the coffee.
It is advisable to wash the inside of the filterholders and filters with a view to avoiding
incrustations and coffee deposits which could fall off during coffee making, forming grounds
in the cup.
2 DAILY CLEANING OF THE STEAM WANDS (K-Kwts-S-M-C-B
The steam wands, used for heating drinks, must be cleaned immediately after use
in order to safeguard against the formation of incrustations that could block the holes
of the spray nozzle and also to ensure that the residue of previously heated drinks does
not deteriorate, leading to the unhygienic formation of bacteria.
3 WEEKLY CLEANING OF THE GROUPS (K-Kwts-S-M-C-B)
1) Replace the normal filter fitted on the filterholder with the blind filter (without holes)
provided.
2) Place 1/2 teaspoon or a tablet of detergent for coffee in the blind filter and couple
it to the group to be cleaned.
3) Start and then stop dispensing at intervals of 4-5 seconds for 5-6 times.
4) Rinse the blind filter and couple the filterholder to the group again.
5) Continue dispensing until the detergent is finished.
6) Make a coffee in order to eliminate any unpleasant tastes.
4 WEEKLY CLEANING OF THE FILTERS AND FILTERHOLDERS (K-Kwts-S-M-C-B)
1) Place three teaspoons of detergent for coffee machines and approx. one litre of boiling
water in a heat-resistant container.
2) Immerse the filters and filterholders in the solution prepared and allow them to soak
for about 20/30 minutes (do not fully immerse filterholders with briarwood handles:
the water and detergent solution would damage the handles).
3) Rinse thoroughly under running water.
5 WEEKLY CLEANING OF THE DRIP TRAY (K-Kwts-S-M-C-B)
At least once a week remove the lower cup grille, remove the drip tray and clean it.
Check and clean the drain box too, removing any dregs with the aid of a teaspoon,
and then rinse it.
6 WEEKLY CLEANING OF THE BODY (K-Kwts-S-M-C-B)
Simply use a damp (non abrasive) cloth.
Do not use alcohol or solvents to clean written or painted parts as this could damage them.
7 CLEANING THE WATER SOFTENER (K-S-M-C-B)
1) Periodically clean the gigleur fitted on the lower water softener valve by unscrewing
it and ensuring that the water hole is not clogged.
2) Refit it on the valve and tighten it.

REGENERATION OF THE WATER SOFTENER RESINS
(K-S-M-C-B)
After the water softener resins have removed a given quantity of calcium and magnesium
salts from the water (water hardness) they rapidly become saturated, losing their softening
capacity. This capacity is completely restored through regeneration, which is carried out
by washing in a salt and water solution.
The efficiency of the water softener will guarantee constantly good coffee quality as well
as the high performance and long life of the machine. Maintenance is also reduced as scale
deposits are not allowed to form in the hot water hydraulic circuit.
Regeneration must be carried out at a maximum frequency of once a week, depending
on the following parameters:
- Size of the water softener
- Hardness of the water
- Water consumption
If the size of the water softener is increased, regeneration may be done less frequently.
The opposite is the case if the other two parameters increase.
As a general reference, with an 8 litre water softener and a water consumption of approx.
25 litres per day, with a water hardness of 30° French degrees, regeneration may be carried
out once every 4 weeks. If, on the other hand, the hardness of the water were 60° French
degrees, it would have to be carried out once every 2 weeks.
If a standard water softener with completely manual valves is installed, follow the instructions
below. If semiautomatic or automatic water softeners are installed, follow the specific
instructions provided in the handbooks accompanying the water softeners themselves.

Close the softener cap after ensuring that it is full to the brim with water and that
no salt residue has been left on the edges of the cap seal.
Turn the upper valve lever totally counter-clockwise.
Unroll the semitransparent pipe of the lower valve and allow its contents to flow into
a general drain or a bucket.
Turn the lower valve lever totally clockwise.
Turn the water supply on: the washing of the resins with the salt solution has begun,
and the liquid will be discharged through the semitransparent pipe.
Continue the resin washing process for an hour. Then ensure that the liquid flowing out
of the semitransparent pipe attached to the lower valve is fresh water (i.e. not salt water).
Turn the lower valve lever totally counter-clockwise and roll up the semitransparent pipe,
detaching it from the discharge outlet.

Service but which are explained to facilitate comprehension and repair operations.
1 WARNING: BUFFER BATTERY ABOUT TO GO FLAT (K-Kwts-S-M-C-B)
The electronic control unit is equipped with a buffer battery that ensures the storing
of the time and date.
The system continually controls the efficiency of the battery, warning in advance when
it is about to go flat and advising its replacement.
The two possible types of alert that are displayed are as follows (K-Kwts o S-M-C-B):
“BUFFER BATTERY ABOUT TO GO FLAT- REPLACE PROMPTLY”
Contact Technical Assistance.
2 STEAM DOES NOT COME OUT OF THE WANDS (K-Kwts-S-M-C-B)
This problem normally arises after the machine has been switched on from cold and
is due to the sticking of the vacuum break valve of the boiler; this does not negatively affect
the use of the machine, in fact:
- After venting all the air through a steam valve, wait until the machine heats up normally
and use it.
In the meantime, contact Technical Assistance.
3 WARNING: WATER LEVEL CONTROL SYSTEM FAULT (K-Kwts-S-M-C-B)
If the following alert appears (K-Kwts):
“WATER LEVEL CONTROL SYSTEM FAULT - MACHINE OFF - REPAIR”
or the following (S-M-C-B):
the fault could be due to:
- Water supply stoppage (K-S-M-C-B): restore it.
- Fault in the boiler water inlet solenoid valve or obstruction to the passing of water
through some parts of the machine.
- Electrically isolating incrustations on the level probe or an interruption in its electrical
connection that prevents the presence of water in the boiler from being detected:
contact Technical Assistance.
84
Downloaded from www.Manualslib.com manuals search engine
This means that the boiler is completely full of water instead of containing a certain quantity
of steam.
The possible causes of this are:
- Fault in the boiler water inlet solenoid valve.
- Electrically isolating incrustation on the level probe or interruption in its electrical
connection.
Switch off the machine, turn off the water supply and contact Technical Assistance
.
5 FLASHING OF THE PUSHBUTTON LED DURING DISPENSING (S-M-C-B)
If, after dispensing selected with an automatic button, e.g. group 1 single short coffee,
the following alert is displayed:
this means that the machine is not detecting the passing of the water.
The possible causes of this are:
- Coffee ground too finely: adjust it
- Water supply stoppage: restore it
- Fault or obstruction to the passing of water through some parts of the machine:
contact Technical Assistance.
6 WARNING OF NOT SATISFACTORY BREWING AND FLASHING OF
THE DISPENSING PUSHBUTTON LED (K-Kwts)
If, after dispensing selected with an automatic button, e.g. group 1 single short coffee,
both the following alerts are displayed:
“BREWING NOT SATISFACTORY - CHECK COFFEE TAMPING OR DOSING OR GRINDING”
the coffee may not have been made according to Italian espresso standards, and therefore
adjustments in tamping, dosing or grinding of the coffee powder are required.
Perhaps even adjustments to temperature or brewing pressure are required
(also consult chapters “F - ADJUSTMENTS” and “G - USE”).
Alternatively, there might be a fault due to:
- Water supply stoppage (K): restore it.
- Fault or obstruction to the passing of water through some parts of the machine:
contact Technical Assistance.

4 WATER COMES OUT OF THE STEAM WAND (K-Kwts-S-M-C-B)
8 A DISPENSING GROUP STARTS UP ON ITS OWN (M-B)
gb
The membrane pushbutton panel has a damaged key or water has entered it:
- Identify the faulty key and, by switching it off and on repeatedly, try to disable
it and do not use it any more.
- Make the water inside the membrane evaporate by drying it with a hair dryer.
In the meantime, contact Technical Assistance.
9 WARNING: INADEQUATE WATER SUPPLY PRESSURE (Kwts)
If the following alert appears on the display:
“INADEQUATE WATER SUPPLY PRESSURE – MACHINE OFF”,
the machine has suspended all of its functions in order to prevent damage to the pump
and other parts.
The possible causes of this are:
- Inadequate water supply pressure: restore it; the machine will resume operation
automatically.
- The water supply pressure is satisfactory but there is a fault in the water treatment
hydraulic circuit:
switch off the machine and contact Technical Assistance
.
10 WARNING: NO WATER IN THE BOILER (K-Kwts-S-M-C-B)
If the following alert appears (K-Kwts):
“NO WATER IN THE BOILER - MACHINE OFF - REPAIR FAULT AND RESET HEATING ELEMENT
SAFETY DEVICE WITH PROGRAMMING KEY”
or the following (S-M-C-B):
Due to the (even temporary) lack of water in the boiler the heating element safety device
may have tripped.
The heating element safety device can be resetted through the Basic Programming,
after the reason for the lack of water in the boiler has been eliminated or repaired
.
Contact Technical Assistance.
11 WARNING: BREWING WATER TEMPERATURE CONTROL SYSTEM FAULT
(K-Kwts-S-M-C-B)
If the following alert appears (K-Kwts):
“BREWING WATER TEMPERATURE CONTROL SYSTEM FAULT - MACHINE OFF - REPAIR”

12 ONE DISPENSING GROUP DOES NOT HEAT SUFFICIENTLY (K-Kwts-S-M-C-B)
gb
There is an obstruction to the passage of the brewing water, i.e.:
- Gigleur protection filter clogged.
- Group natural heating circuit clogged with scale deposits.
Contact Technical Assistance
13 THE GAUGE SHOWS A BOILER PRESSURE NOT BETWEEN 0.6 AND 1.6 BAR
(S-M-C-B)
Unless this value exceeds 1.8 Bar, in which case switch off the machine and contact
Technical Assistance, this is a fault that does not negatively affect the use of the machine.
The most likely cause is related to calibration problems with the pressure gauge.
Contact Technical Assistance.
14 THE GAUGE SHOWS A BREWING PRESSURE NOT BETWEEN 8 AND 9 BAR
Unless this value exceeds 12 Bar, in which case switch off the machine and contact Technical
Assistance, this is a fault that does not negatively affect the use of the machine.
The most likely causes are that the pump is out of calibration or worn.
Contact Technical Assistance.
15 WARNING: WATER SOFTENING SYSTEM FAULT (Kwts)
IIf the following alert appears on the display:
“WATER SOFTENER SYSTEM FAULT – MACHINE ON - REPAIR”,
this is a fault that does not negatively affect the use of the machine.
To dispel all doubts regarding the actual presence of a fault as opposed to the existence
of other anomalous situations not connected to the machine, it is advisable to run
the following procedure:
1) Switch the machine off and then on again: the following alert will appear on the display:
“WATER SOFTENER RINSING IN PROGRESS – DURATION 60 MINUTES – MACHINE ON”
wait, while continuing to operate the machine.
2) Once the rinsing cycle has been completed, the following alert will appear on the display:
“LOAD SALT AND PRESS ENTER - MACHINE ON”:
follow these instructions because the machine wants to regenerate the resins in order
to repeat the various controls.
If the fault alert reappears, contact Technical Assistance.
This aim of this automatic procedure is also to protect the machine from using salty
regeneration water due to a fault.
If the machine is switched off (e.g. for repairs) while this alarm is still in course, when
it is then switched on again, before using the water from the softening circuit, it automatically
runs a complete rinsing cycle on the circuit, after which it carries out another regeneration,
continuously monitoring the suitability both of the fresh water and of the salt solution used
for washing the resins.

16 NO SALT LOADING (Kwts)
gb
If “ENTER” is erroneously pressed before the salt is loaded in the water softener,
do not try to open the water softener. Proceed as follows:
1) Wait, while continuing to operate the machine: after approx. one hour, the following alert
will be displayed:
“WATER SOFTENING SYSTEM FAULT - MACHINE ON - REPAIR”
as the machine expects it to be utilized correctly and when it detects the absence
of salt in the resin washing water, it diagnoses a fault.
2) Switch the machine off and then on again: the following alert will appear on the display:
“WATER SOFTENER RINSING IN PROGRESS - DURATION 60 MINUTES - MACHINE ON”.
Wait, while continuing to operate the machine.
3) Once the rinsing cycle has been completed, the following alert will appear on the display:
“LOAD SALT AND PRESS ENTER - MACHINE ON”
at this stage, you have returned to the initial point of departure.
It will therefore be possible to carry out salt loading and confirmation of the same correctly.
17 THE WATER SOFTENER AND ACTIVATED CARBON CARTRIDGE CAPS
DO NOT OPEN (Kwts)
This problem may arise both during installation and during use when the machine requests
salt loading or the changing of the activated carbon cartridge.
This is due to the fact that the machine has been previously switched on or used without
the water softener and the activated carbon cartridge being completely topped up with water
in order to safeguard against the presence of pressurized air in the hydraulic circuit:
1)
2)
3)
4)
5)
6)
7)
8)
Switch off the machine.
Close the water supply.
Loosen the fitting on the water softener flexible connecting pipe marked “1” until internal
pressure has been totally blown off.
Close the fitting.
Open the softener cap, top up with water and reclose.
Open the activated carbon cap, top up with water and reclose.
Open the water supply again.
Switch the machine back on again.

1) Clean the drain box and use a metal wire to free the drain pipe of residue.
2) Eliminate any sagging or strangling of the flexible drain pipe, ensuring that it is always
angled downwards in a straight and even manner.
3) If the above-mentioned causes are not responsible for the fault, this means
that there is a blockage in the drain pipes external to the machine: contact a plumber.
Also consult chapter “E – INSTALLATION”.
