Controls Overview
Miele dishwashers are currently categorized into three (3) product
series, based on the type of controls.
Novotronic
Each Novotronic model dishwasher can be operated with a single
knob. Surface mounted design technology (SMD) allows Miele
Novotronic components to be extremely durable and reliable. These
controls are capable of performing hundreds of tasks which cannot be
handled by mechanical components.
Touchtronic
This new series of Miele dishwashers is operated by pushing a single
button -- no separate temperature or drying selections -- just turn the
machine on, pick a program and Miele does the rest. All models now
include a Pots and Pans program and a Water Management System,
designed to maximize cleaning results and optimize water and energy
conservation.

Water Softener
If your tap water hardness is above 8 grains per gallon (140 ppm), the
water should be softened.
A Water Hardness Test Strip is used to determine the water hardness.
If the Water Softener is needed:
ƒ The dishwasher must be programmed to “with Water Softener”
(ON).
ƒ The Water Softener reservoir is filled with softener salt.
ƒ The water hardness level is programmed into the dishwasher
electronic.
If the Water Softener is not needed:
ƒ The dishwasher must be programmed to “without Water
Softener” (OFF); however the hardness level is not programmed
into the electronic
ƒ Salt is not needed and should not be installed.
Water Softener Salt
Only use water softener salt specially formulated for dishwashers.
Other salts may contain insoluble additives that impair the Water
Softener. The proper salt can be purchased from the Miele Technical
Service Department.
To add salt:
1. Remove the Lower Basket.
2. Unscrew and remove the Salt Reservoir Cap located on the
floor of the Wash Cabinet.
3. If this is the first time salt is installed; add 2 quarts water.
4. Place a funnel over the Salt Reservoir. Carefully fill with salt.
Note
The Salt Reservoir holds approximately 4.5 lbs (2 kg) of
salt.
5. Clean any excess salt from the threads of the reservoir
opening; and screw the cap on firmly.
6. Run the "Rinse & Hold" program to remove any traces of salt
from inside the Wash Cabinet.

Description of Function
4.1
Cabinet Construction
The inner cabinet is constructed of stainless steel (1.4301) welded
onto four (4) vertical U-section sub-frames. The cabinet is sound and
heat-insulated with bitumen and/or mineral wool matting.
4.2
Fan Assembly
(Units equipped with Turbothermic Fan)
The fan assembly consists of the Fan Motor (M2) and a PTC Release
Element (Y56), which opens the air outlet flap. The 120VAC fan
operates in the drying stage, after a brief delay. The PTC Release
Element is activated, and the Air Outlet Flap is partially opened. A
bypass channel behind the air outlet is also opened and ensures that
the moist air from the cabinet is mixed with dry air from the door
interior. This measure prevents condensation from developing. After
about a minute, the electronic switches off the Release Element,
however the Air Outlet Flap remains partially open. After a few minutes
the Release Element is activated again, which completely opens the
Air Outlet Flap. The fan operates constantly throughout this period
until the program ends.. The Air Outlet Flap remains open at program
end and closes when the dishwasher door is opened.
4.2.1
PTC Release Element
(Units equipped with Turbothermic Fan)
When 120VAC is applied to the Release Element, the PTC Resistor
heats a small grease-filled capsule. As the grease expands it pushes a
piston upward and slides the Air Outlet Flap to a partially open
position. When the Release Element is activated the second time, the
piston slides the Air Outlet Flap to a fully open position.

Combination Dispenser
4.3.1
Construction
Two individual solenoids control detergent and rinse aid dispensing.
The Rinse Aid Reservoir has a capacity of about 130 ml. When the
Rinse Aid level drops to about 25 ml. the Magnetic Float activates a
Reed Switch on the edge of the dispenser and the Rinse Aid LED
illuminates.
Figure 4-1: Dispenser Assembly

G600 & G800 Electronic Dishwashers
Technical Information
4.3.2
Dispensing
During the main wash, the Detergent Solenoid (Y51) is energized
(120VAC), to open the Detergent Dispenser Flap. The water jet from
the Middle Spray Arm flushes detergent out of the dispenser.
Table 4-1: Detergent quantity in Combination Dispensers C2.06 and C2.09.
During the final rinse the Rinse Aid Solenoid (Y50) is energized
(120VAC), to open the dispenser chamber and allow Rinse Aid to be
dispensed into the cabinet.
Note
The Rinse Aid only flows from the reservoir into the dispenser chamber
when the front door is fully opened at the end of a program.
The quantity taken into the dispenser chamber depends on the
dispenser selector setting.
Table 4-2: Rinse Aid Dispensing (Combination Dispensers C2.06 and C2.09).
When the Rinse Aid Light turns on, an additional 2 to 5 dispensings (at
setting 2) remain available.

Technical Information
Note
To allow proper filling of the Rinse Aid Dispenser; Rinse Aid should
only be added with the door in the fully open position.
4.4
Heaters
During the main wash and final rinse portions of a wash cycle, the
water is heated to the programs specified temperature before
advancing to the next step in the program (i.e.Thermal Stop).
The water is heated using one of two systems:
4.4.1
Wash Cavity Heating Element
Figure 4-2: Cavity Style Heater Element
The Heating Element is mounted just off the floor of the wash cavity.
When powered (120 VAC) the element radiates heat thereby heating
the surrounding and circulating water. The temperature of
the water is monitored by the Temperature Sensor, mounted in the
Sump.
Heating Element switching is performed by the electronic via a Relay.
The relay (when energized) closes contacts to provide the Heater
Element with 120VAC. A Temperature Limiter mounted with the
element provides protection by opening up the circuit should the
temperature become to high.

4.4.2
Flow Through Heater:
The Flow Through Heater
Assembly is mounted on the (left
side) exterior of the wash cabinet.
The Flow Through Heater is
plumbed into the water path
between the Circulation Pump
Output and the Middle Spray Arm.
The Flow Through Heater Consist
of a Heater Element mounted
parallel to a metal tube that water
passes through when the
dishwasher is circulating.
As water flows through the metal
tube; the water is heated and exits
through the Middle Spray-Arm. As
the water falls to the bottom of the
wash cavity, it passes through the
filter and re-enters the Circulation
Pump - the process then repeats.
The Temperature Sensor monitors
the water temperature until the
programs specified temperature is
reached. Generally the water heats
about 20 per minute.
Figure 4-3: Flow Through Heater
Heating Element switching is performed by the electronic via a Relay.
The relay (when energized) closes contacts to provide the Heater
Element with 120VAC. Two Temperature Limiters are mounted along
the element and provides protection by opening up the circuit should
the temperature become to high.

Pulsed Heating - Operation
In certain programs the heating may be operated at full power until a
water temperature of 77°F is reached; then power is applied in pulses.
This extends the heating time and allows enzyme-containing
detergents to develop their full cleaning potential.
The pulsed heating operates as follows:
• 1 min heater element on.
• 1 min heater element off.
The number of pulse cycles is limited to a maximum of 11. If the
programs specified temperature has not been reached, the heating
resumes using full power. Once the programs temperature has been
reached, the electronic unit advances to the next step in the program.
If the temperature cannot be reached (i.e. heater failure) within a
specified time, the program will advance; and a heating fault is stored
in the electronic.
4.7
Temperature Protection
The Flow-through Heater uses two (2) Temperature Limiters (2F2)
mounted on the body of the Flow-Through Heater. The Temperature
Limiters are designed to open the circuit should the temperature
become too high. When the temperature falls, the Temperature
Limiters do not reset automatically and must be reset manually (via the
red button on the back of the device).
Additional protection is provided by the Electronic, which switches the
appliance off and stores an F4 fault code, should the temperature
exceed 194°F (90°C) – as determined by the Temperature Sensor.
4.8
Static Drying
The Static Drying System uses no electrical and / or mechanical
components to assist in drying. With this system the final rinse water is
heated to 154°F (68°C) (not the usual 150°F / 67°C). The dishwasher
cabinet is made of stainless steel; and conducts the heat generated
during the final rinse. As the final rinse ends this stored thermal energy
radiates and assists in the drying.

WaterProof System (WPS)
The Water Inlet Valve (Y2) consists of two (2) electro-mechanical
valves mounted within a waterproof box located at the water
connection (end of the water intake hose).
The valves are mounted in physically and electrically in series to
ensure that if one valve should fail (e.g. due to blockage caused by a
foreign body) the water flow will still be switched off by the other valve.
Figure 4-6: WaterProof System Connection
The water inlet system is protected by WPS (WaterProof System)
which uses an outer sleeve protecting the water inlet hose and valves.
In the event a valve or the hose should leak, the leaking water will flow
along the outer sleeve to the drip tray in the bottom of the unit. When a
quantity of water collects in the drip tray, the Float Switch (B8/3) is
actuated.
33
G600 & G800 Electronic Dishwashers
Technical Information
With the Float Switch actuated; power that is normally distributed
throughout the appliance is re-directed to the Drain Pump. The Drain
Pump will continuously operate when the unit is turned on and the door
is closed. Normal operation and Program Selection is not possible
during this time.
Warning!
● If the WPS is replaced, always ensure the correct flow restrictor is
installed
● The WaterProof system only operates with the door closed and the
dishwasher switched on.
● To ensure optimal protection, the water connection should be at
least 20 cm higher than the floor on which the dishwasher is
standing.
● The connection hose must be routed so that no point is higher than
the connection housing.
For further details, refer to the model specific Operating and
Installation Manual.

Water Mixing
4.15.1
Water Mixing - External Flowmeter
Refer to figure 4-9.
The main water flows into the WaterProof system (Item 10), to the
Water Intake Assembly where it passes a Non-Return Device (Item 6).
The Non Return Valve prevents a reflux of water from the machine into
the supply should a vacuum develop in the system.
The water path is then divided at the bypass (Item 5), and up to 5% of
the water flows directly into the cabinet without passing through the
Water Softener. Depending on the Water Hardness Selector Setting
(Item 4), a proportion of the water flows directly into the cabinet via the
Cabinet Ventilation, (Item 9). The remaining water fills the reservoir in
the Water Inlet (Item 7), for later reactivation of the softener. When the
reservoir is full, water flows through the Ion Exchanger (Item 14), and
the intake opening in the sump (Item 2), to enter the cabinet.
Mains water mixing (External Flowmeter)
Figure 4-10: Water Hardness Selector
With correct programming and operation the water softener should
supply water with a hardness level < 4° in all wash programs. With
certain types of glass it may be necessary to set the wash water
hardness individually to avoid possible glass corrosion. Depending on
the water hardness, the selector at the Water Intake (Non Plus Models
Only) must be set to between 0 - 3. This sets the quantity of mains
water flowing directly into the cabinet without passing the Water
Softener. For details, see the model specific operating manual.

Solenoid Valve (Y5) - Operating (Plus Models Only)
Figure 4-13: Water Hardness Mixer Solenoid
Refer to figure 4-12.
With no voltage to Y5
The Valve Pin (Item 5) closes the channel for cabinet ventilation. The
non-softened water then flows behind the Valve Pin (Item 5.1), through
an opening in the Water Channel (Item 3.2). From here it flows
upwards to the Ball Valve (Item 6), where a small proportion of the
water passes through a small bypass in the Ball Valve to the Water
Reservoir (Item 7), for later use during softener reactivation.
Note
After softener reactivation, the reservoir is filled again by the time
the third water intake has taken place.
The majority of the water, blocked by the Ball Valve at the Water
Reservoir Inlet, flows through the Water Channel (Item 3.3), to the
Water Mixer Outlet and then to the Water Softener, (Item 5). After
passing through the Water Softener, the now soft water flows via the
Soft Water Intake (Item 12), back into the Water Inlet Mixer. It then
flows past the Non-Return Device (Item 9), into the Sump, (Item 13).
With voltage applied to Y5
The Valve Pin is drawn back and a portion of the hard water flows
through the hole into the channel (Item 3.1), via the Cabinet Ventilation
Port. This mixing of hard water with the soft water allows the wash
water hardness to be adjusted more precisely.

4.16 Electronic Controlled Water Hardness (EGS)
To avoid possible glass corrosion, the wash water hardness level
should not exceed or fall below
ƒ
ƒ
45 ppm in programs with heating
71 ppm in program without heating
With water hardness below 286 ppm (in heating steps under 232 ppm)
the Solenoid Valve Y5 is activated to add a proportion of hard water to
the cabinet. The proportion added in this way is fixed and depends on
the mains water hardness level programmed into the electronic.
The EGS system is not active in all wash programs, however it can be
programmed if required. The additional function Top Solo has no
influence on the EGS system.
The EGS system is not active in the following cases:
● In programs Universal Plus 55°, Universal Plus 65° or Economy
(standard setting).
• If the programmed water hardness is above 286 ppm.
• In the program when the softener is being reactivated.
• When flushing the Water Softener after reactivation.
• If no Water Softener is fitted.
• If the function “Without Softener” has been programmed
Note
If a water softener is fitted but has been deactivated (programmed to
“without water softener”), then the incoming water flows directly into
the cabinet via the Solenoid Valve only. However a small quantity
(approximately 1 liter) of water still flows through the Water Softener
System to prevent mold from forming.

Water Softener
The Water Softener consists of 2 compartments - a Salt Container and
an Ion Chamber. In addition it also has a mechanical Non-Return
Valve, a Solenoid Valve and a Reed Switch / Magnetic Float Switch.

Incoming water flows through the Intake Assembly and into the Ion
Exchanger. When the water flows through the Softener, the calcium
and magnesium ions are exchanged for sodium ions which soften the
water. The softened water flows into the cabinet via a port in the Sump.
43
G600 & G800 Electronic Dishwashers
Technical Information
4.17.1
Reactivation
The electronic unit activates the Softener Valve (Y38/1) and water from
the Water Intake Assembly flows into the Salt Container, where it
dissolves a quantity of salt to become a brine mixture.
The saturation point, above which the water cannot dissolve any more
salt, is approximately 40%. The brine then flows past a mechanical
Non-Return Valve into the Ion Exchanger and flushes the existing
water into the Sump. The built-in Non-Return Valve in the Softener
prevents the brine mixing with the incoming water during normal
operation.
The brine flushes the resin in the Ion Exchanger, and replaces the
retained calcium and magnesium ions, with sodium ions. At the next
program start, the incoming water flushes out the remaining brine and
hardness minerals before the actual dishwashing program begins.

The salt in the Salt Container is sufficient for several reactivation
cycles as it is not dissolved all at once. As the quantity of salt in the
Salt Container reduces, the concentration of the brine decreases.
When a specific concentration is reached, the Float (containing a
magnet) activates the Float Switch. The Salt Indicator is then
illuminated to advise the operator the softener system needs salt
added.
The dishwasher operates with consumption-linked reactivation. After a
certain number of programs (Refer to Table 4-6), the Electronic
activates the Solenoid Valve (Y38/1) at the end of the Final Rinse
Cycle and starts the reactivation process. If several other programs are
operated between two Universal 65°C programs such as Economy, the
electronic unit calculates the probable quantity of water used and the
approximate number of equivalent Universal 65°C programs. Therefore
the figures provided in Table 4-6 can only be considered as a guide
only.

Operation
An air inlet port is located on the back / left area of the cavity ceiling.
An air duct is fitted to the port and attaches to the Condenser
Assembly.
During the Drying portion of a program, moist air within the cabinet is
drawn through the Condenser Assembly via the Condenser Fan (M2).
As the cabinet air passes the Cold Water Reservoir (inside the
condenser) water vapor forms and exits the condenser (as water) via
the port on the left wall of the cabinet.
The cooling bank within the Condenser Assembly utilizes water from
the intake / softening system controlled by the electronic via the
Condenser Control Valve (Y6).

Refer to figure 4-15…
The Miele Circulation Condenser Drying System consists of a Steam
Condenser (Item 4), with Circulation Fan. The Steam Condenser
contains a Cold Water Reservoir over which an air duct passes and
moist air from the cabinet is passed through this air duct. The cold
water and the air duct are separated by a 0.5 mm thick membrane
which provides the condensing surface. The Fan (Item 2), takes in
moist air from the top of the cabinet (Item 5), and passes it over the
condensing surface where it is cooled then blows it back into the
cabinet via the opening in the lower area of the Side Panel (Item 3).
The water vapor that is condensed out during cooling flows down and
enters the cabinet via the opening in the lower area of the Side Panel.
Some vapor may condense out in the Fan and this flows out via a hole
in the bottom of the Fan Housing to the Drip Tray where it evaporates
1 Soft water from Water Softener

Figure 4-16: Control Valve Y6
Refer to figure 4-16.
No voltage applied to Control Valve Y6
The path between positions 1 and 3 is always open so during every
water intake the Cold Water Reservoir in the Steam Condenser is filled
with water from the Water Softener. If the Reservoir is full, excess
water overflows at its top edge and flows down then enters the cabinet
via the opening in the lower area of the Side Panel.
Voltage applied to Control Valve Y6
If voltage is applied to the Control Valve during water intake stages,
the path between 1 and 2 is also open (this is marked with +K in the
Program Timing Chart). In this way soft water flows to the Water Mixer
and then into the cabinet.

Drain Pump, Circulation Pump
The Drain Pump (M8) is located below the cabinet and connects to the
right / front of the Sump. The Pump removes the wash water through
the Non-Return Valve and Drain Hose to the on-site drain. The Drain
Pump is controlled / powered by the electronic.
Note
If the on-site drain is below the level of the guides for the bottom
basket, the drain must be vented to prevent siphoning. See the
appropriate operating/ installation instructions or call Technical Support
for assistance.
During dishwashing, the Circulation Pump (M6) takes in the wash
water from the side of the Sump through the Microfine Filter and the
Large Surface Area Filter and pumps it to the Spray Arms. During
drainage, the Drain Pump removes water out from below the Microfine
Filter. This change of direction in the water flow assist in flushing out
any residues that may have been retained within the Filter. Water
passing through the Non-Return Valve and then to the on-site drain.
A Bimetallic Switch is integrated in the Circulation Pump Motor
Windings and serves as a safety cut-off should the temperature
exceed 150°C (302°F). After a cooling-down phase, which can be
between 10 min - 1 hour the Switch resets automatically. If the Switch
is faulty, the Motor Assembly must be exchanged.

Top Solo Valve
Refer to figure 4-19.
If the Top Solo option is selected, water is directed to the Top and

the Circulation Pump and the Sump within the plumbing circuit to the
Bottom Spray Arm. When Top Solo is selected an electromagnet (Item
3), releases a plastic ball in the water intake, wash and / or rinse
stages into the valve body (Item 2). This ball is now unlocked and the
water pressure pulls it free of the bottom part of the valve and presses
it against the output opening (Item 4). This almost completely closes
the channel to the Bottom Spray Arm. A bypass opening (a small
square cutout in the output opening) allows a minimal quantity of water
to flow to the Bottom Spray Arm so keeping the jets free of food
residue deposits.
Note
The Top Solo Valve is activated after 2.5 liters of water is present
inside the appliance.

Turbidity Sensor (ECO Sensor)
Certain model dishwashers are equipped with a Turbidity (ECO)
Sensor. The Sensor is comprised of a Phototransistor that emits a
beam of light through the water path. On the opposite side of the
sensor is a Photoelectric Switch (receiver). The amount of light
capable of passing through the water is based on the turbidity
(transparency) of the water. The amount of light received, effects the
current flow of the sensor, and is used by the Electronic to calculate
the condition of the water.
If clean water is present, the light flow is near 100%. As the water
becomes dirty the amount of light received is reduced.
During certain steps of the program (refer to the model specific Timing
Chart) the Sensor is monitored to determine the condition of the water.
Example
At the end of the Pre-Wash the water is checked via the Turbidity
Sensor. If the water is clean enough, the program will change by
eliminating the drain at the end of the Pre-Wash and fill at the
beginning of the Main Wash. The same water will continue to be used
to reduce water consumption.
If the Turbidity Sensor and electronic determine the water to be “dirty”.
Then the program will continue with a drain at the end of the PreWash, and a fill during the Main Wash.

G600 & G800 Electronic Dishwashers
Technical Information
The sensor is located within the plumbing connection between the
Circulation Pump and Top Spray Arm. In order to compensate for
residues on the sensor and ageing of the optical system, the Turbidity
Sensor is re-calibrated automatically every time the dishwasher runs a
program (the steps on the Timing Chart are marked with a “T “). To
prevent residues drying on the sensor surface, the sensor remains in
water after the drainage cycle.

Electronic Unit - Power Outputs
The Electronic Unit controls all components within the dishwasher.
The activation of components requiring 120VAC power is handled by
Thyristors and Relays within the Electronic. The individual components
of the Electronic are not replaceable. Should the Electronic require
replacement; the Electronic is replaced as one assembled component.
