Fisher & Paykel DD601IV2, DS601V2 Filter Plate, Drain Cycle, Overheating Control, Filter System

3.8.4Overheating Control

The heater plate is only activated during the wash cycles. It is not used for drying. The temperature is maintained by the thermistor. The element circuit is continuously monitored by the electronic controller and will switch a fail safe relay if a fault is detected in the heater circuit. The element is thermally monitored by the thermistor on the element through the electronic controller.

3.9Filter Plate

The filter plate is a stainless steel disk which lies below the dishrack and sprayarm and completely encompasses the base of the tub.

3.9.1The Filter System

The tub is designed with vanes which swirl the water around and over the filter plate. At the front of the tub, located as part of the filter plate, is the drain filter. Large soils collect in the drain filter and only 1.5mm or smaller soils flow through its micro mesh filter, eliminating re-depositing of soil during the wash. Only soils up to 6mm pass through the drain filter during the drain cycle. This requires the drain filter to be regularly emptied and cleaned.

3.9.2Removing and Cleaning the Filter Plate

The drain filter can be emptied with the dishrack in place by removing the cutlery basket and opening the plastic section of the dishrack. The filter plate is removable for cleaning by removing the dishrack and sprayarm and unlocking the lockring nut anti- clockwise.

3.10Drain Cycle

The drain pump is a self priming centrifugal pump which only pumps when the motor is rotating in the drain direction (anti-clockwise). It has a five bladed impellor made from acetal pushed into a spline on the end of the rotor shaft. The drain cycle is a 60 second timed drain period.

The drain pump housing, which incorporates an inlet and outlet pipe, is welded to the motor housing, hence captivating the motor.

The inlet pipe plugs straight into the sump and is sealed there by a small ‘o’ring.

The outlet pipe has a non return flap valve to prevent soiled water returning to the tub.

The drain hose is an extruded blow mould hose which is routed over the link assembly and exits out of the base of the product and is connected to a domestic drain.
