The motor is a fully electronically controlled 80V, 60w,

selected, and at approximately 5000 rpm on drain.

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.
There is an O-ring around the top edge of the motor
rotor which seals against the filterplate.
3.4.2 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.
The spray arms rotate at approx 11 rpm.
