Wash Cycle, Heating | Fisher & Paykel DD601V2, DD601IV2, DS601V2

3.7Wash Cycle

3.7.1Tub

The tub is the main cavity where all the wash activity occurs. The tub is a plastic recepticle which has a wash pump and sprayarm at the base. The tub also has guide vanes around its walls which direct falling water from the wash cycle in a clockwise direction around the filter plate. This clears the filter plate of food particles into the sump where they can be trapped or pumped out during the drain cycle.

3.7.2Rotor

The rotor is a four pole permanent magnet rotor with a graphite bearing at each end of the vertical shaft. At the lower end of the rotor shaft is the drain impellor and at the upper end is the wash impellor.

3.7.3Spray Arm

The spray arm is shaped for most efficient waterflow. The holes are positioned for best penetration into the washload, with the water jets angled to ensure the sprayarm rotates at the most efficient speed.

3.8Heating

3.8.1 The Element

The heater plate is an element consisting of a porcelain enamelled steel plate with a thick film resistive circuit written onto the dry side. The element is clamped in place by a lockring nut and supports the motor at the base of the tub.

3.8.2 Heating the Water

The heater plate lies beneath the filter plate. This creates a flow through water heating system during the wash cycle by allowing water to flow through the filter plate, over the surface of the element and into the wash pump.

3.8.3 Maintaining the Temperature

Attached to the element is a sub printed circuit board with a temperature sensitive thermistor . This connects by means of a RAST 2.5 connector system to the wiring harness of the element. Sensor components are unservicable.
