5.2.34 Wash Motor/Pump - Disassembly
5.2.34.1 Place the wash motor/pump on the rear diecast
end-shield on a table or suitable flat surface. While viewing
the wash motor/pump assembly from the pump cover end,
position the two support hooks formed on the diecast end
shield at the twelve o’clock position. It should be noted the
pump outlet nozzle for the water supply to the upper spray
arm is at the nine o’clock position, while the pump outlet for
the lower spray arm is at the four o’clock position. The
alignment of the pump cover to the two support hooks
on the diecast end-shield of the motor must be main-
tained for correct installation of the wash motor/ pump
to the dishwasher.
5.2.34.2 Directly below the pump outlet located at the four
o’clock position (lower spray arm water supply) on the outer
diameter, is a 1/8" diameter round locator. This locator fits
into a slot on a corresponding black plastic flange, which is
known as the pump plate.
5.2.34.3 Align the small locator and corresponding cutout
(1/8" wide) and mark this location onto the diecast flanged
end-shield of the wash motor (four o’clock position) with a felt
tipped marking pen for reassembly purposes. Note also that
the four o’clock position is identified by the electrical input
wires entering the stator at this position.
5.2.34.4 Remove the four Phillips head screws which hold
the pump cover to the pump plate and wash motor flanged
diecast end-shield.
5.2.34.5 Lift clear the pump cover and the neoprene “O” ring
which seals the pump cover to the pump plate.
5.2.34.6 The pump impeller must be removed to access the
removal of the pump plate.
5.2.34.7 To remove the impeller from the shaft, insert a
screwdriver into the opposite end diecast end-shield air
cooling vents and engage with a blade of the cooling fan
(eight diecast blades on rotor), to lock the rotor in a
stationary position. While holding the screwdriver firmly,
grasp the impeller and turn in an counter clockwise direction
to unscrew the impeller from the shaft. Lift the impeller clear
from the pump shaft.
Screwdriver inserted into cooling vents/blades to lock shaft.
5.2.41.8 The flanged pump plate which houses the carbon
faced rotary seal and bellows can also be lifted clear from
the wash motor.
NOTE: A priming vane is attached to the pump plate, which
can be removed. The white polycarbonate priming vane
ensures the pump will prime and not cavitate. If necessary,
remove and reinstall.
5.2.41.9 Upon lifting the pump plate clear, the flanged
diecast end-shield of the wash motor will be visible. A black
plastic water slinger is attached to the motor shaft. This
slinger is housed by an annular projection with a cutout at
the six o’clock position. It allows water leaking past the rotary
seal to exit the flanged diecast end-shield.
5.2.41.10 Refer to section 5.2.35 to reassemble the wash
motor/pump.
