Motor; Motor Rotor; Spray Arm; Filter Plate - Fisher & Paykel DishDrawer DD60 Series Service Manual

4.9 Motor

The motor is a fully electronically controlled 3 phase, 6
pole brushless DC motor, running on wash at between
2200 - 2800 rpm depending on the cycle selected, and at
approximately 5000 rpm on drain.

4.10 Motor Rotor

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.

4.11 Spray Arm

The spray arm is shaped for most efficient water flow. The
holes are positioned for best penetration into the wash
load, with the water jets angled to ensure the spray arm
rotates at the most efficient speed. There are 2 sluicing
jets located at the bottom of the spray arm to direct soils
into the drain filter.

4.12 Filter Plate

The filter plate is positioned below the dish rack and spray
arm.
The filter plate has a rubber over mould around the edge
and centre to reduce soil re-depositing.
These improvements will ensure a better wash
performance.
The drain filter fits tightly into the filter plate, due to the
rubber over mould around the edge.
