Tub and Door Seal
The door seal is pressed into the tub
channel for an interference fit. Center the
gasket (marked on back) at the tub top
center and press in place without stretching
or bunching. The gasket takes a short turn
at the bottom of the tub channel before
ending at the channel end wall.

Pump Assembly
1
The pump assembly is driven by a
/12 HP,
shaded pole motor. Rotation is in the
counterclockwise direction at 3100 to 3200
RPM. The motor drives a pump which
supplies 100 percent filtered water at a rate
to approximately 12 GPM.
Draining is accomplished by using a small
separate synchronous drain pump mounted
to the side of the sump. The drain pump is
connected to the main pump by a small
rubber hose. The drain check valve is
located at the entrance to the drain pump.
The drain hose is attached by a worm gear
clamp to the discharge of the drain pump.
The drain is then routed up the side of the
dishwasher and attached to the side of the
tub. This drain loop insures that an air
pocket cannot form near the drain pump
900 Watt Heater
Refer to the cycle chart on the reverse side
to determine when the heater is on during
the wash cycle.

and cause the pump to air lock. The drain
loop on the side of the tub must be kept in
place after servicing.
The main pump can easily be removed by
disconnecting the drain pump connector
hose and the wiring harness connections
made at the circulation motor. Once the
pump assembly is removed from the
dishwasher, the motor/impeller assembly
can be removed from the sump by taking
out the five (5) T-20 Torx head screws from
the plastic motor bracket and then the three
(3) T-20 Torx head screws from the volute
cover. Using a large flat head screwdriver
inserted between the impeller screw and
the sump’s volute, the motor/impeller
assembly can be gently pried out of the
sump. Use the screwdriver as a lever.
Voltage checks of the heater should be
made with the timer set in the main wash.
