4.0 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.

4.3 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.

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.
G600 & G800 Electronic Dishwashers
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.

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 Figure 4-3: Flow Through Heater
about 20 per minute.
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.

Technical Information
4.6 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.
