Drain Solenoid

!
WARNING
Power must be disconnected before attempting to
measure electrical resistance.
1. Check continuity of solenoid coil on low ohm scale.
2. Check armature for binding. The armature should
bottom before the gate is completely closed.
Mounting plate must not be bent.
3. When replacing solenoid coil, both springs must be

Racks

The lower rack rollers are the same on all models.
Two slight depressions have been molded into inner
door liner to avoid roll in of lower rack when pulled out
for unloading. The two front rollers rest in these
depressions when lower rack is fully pulled out.
To remove upper rack, remove plastic retainer caps on
the ends of the slides. The retainer cap can be removed
with a flat blade screwdriver, by prying back the member
that fits into slide and then pivoting retainer cap inward.
Assemble cap in reverse order.

Rotating Upper Shower Arm

This option is not used on all models.
Hose to rotating upper shower arm connects to port in
pump housing supplying water during wash and rinse
periods. If upper shower arm is not used, a rubber cap is
clamped over this port on pump housing.
Nozzle is a single plastic part which snaps into power
shower spray arm. Studs on nozzle are inserted into top
of the tub (from inside of tub). Metal palnut fasteners
are then driven onto studs to secure plastic nozzle plate
to top of tub.
