COMPONENT DESCRIPTION

Module

Mounted behind the plinth, this is an electronic device that monitors and controls all devices within the
appliance. If replacing this module, refer to the Module Programming section on in this manual.
Both DEA700 and DEA603 Modules have been used in Production.
The DEA700 Module was used in Production up to Industrial Code ending 2500.
From Industrial Code ending xxxxxx2500, the Electronic Module changed to a DEA603 variant.
Note: (xxxxx is the Dishwashers Commercial Code).
DEA603, is a Stripped variation of DEA700. There is no change to the Programmes or Operation of
the machine.
The 2 module types ARE NOT interchangeable, and the correct settings file must be used with the
correct module.

Fill Valve

The appliance has an electromagnetically operated solenoid valve, which is connected to the water
supply.

Water Turbine

This is situated at the bottom of the Air Break. Consisting of a fixed reed switch and a magnet fitted to
an impeller. Unlike previous control systems, water fill is no longer dependant on the operation of the
pressure switch. The turbine generates a series of impulses as the water rotates the impeller vanes.
The control module translates these impulses into litres of fill water (268 impulses is equal to 1 litre of
water). The turbine also regulates the maximum amount of water that can enter the tub, therefore
acting as an overflow device.
Note: Machines with DEA603 Module fitted. If the Turbine senses a fill rate less than 0.9 litres/minute,
the fill will be measured by Time. (Using previous Stored History of fill times)
Pressure Switch
The Pressure Switch confirms to the Module the overall volume of
Pressure Switch
water inside the tub and signals if the Heater can be turned on or a
Fault Code Displayed. (see page 6)
The pressure switch and associated wiring is Low Voltage
(12 volts and 10 mA) with RAST 2.5 connector.
The pressure switch indicates the full state only (appliance filled with
water).
Empty level is signalled when the pressure switch is not signalling
full.
