Tub Displacement Sensor Diagnostics

CAUTION: Do not perform continuity check directly on
Displacement Sensor due to the potential for damaging
the microprocessor chip in the sensor.
1. Enter the Service Mode by pressing and holding
the Enviro Plus and Spin Only keys for three
seconds.
Press the Super Wash key.
2.
3. Press Delicates.

beyond the #2 mark m olded on slider. Display will
show "UO" (Unbalance open).
5. Press Hand Wash.
6. Pull tub to front left corner and push down so
sensor collapses to before the #1 mark m olded on
slider. Display will show "UO" (Unbalance open).
NOTE: Moving the sensor midway between m ark #1

Special Instructions Water Leak Around Pulley On
Tub Bottom
W ater leaking around the pulley on the bottom of the
tub, check the following:
1. Rem ove the Transmission. The Transmission
should be approx. 1/3 full of oil. The oil in the
Transm ission should be thick, similar to a high
viscosity motor oil. Tip the Transm ission slightly, the
oil should m ove slowly. If the Transmission is nearly
full or if the fluid is very thin and m oves quickly, the
Transm ission has water in it. Replace the
Transm ission, O-Ring, Spinner Support, Tub Seal
and Outer Tub.
2. If no water is inside the Transmission, check the
integrity of the O-Ring. Look for signs of water or
rust on and around the Input Shaft. If the O-Ring is
bad or there are signs of water or rust around the
input shaft, replace the spinner support, tub seal
and the outer tub.
3. If there was no water in the Transmission or around
the top of the Input Shaft, it is likely the water was
leaking through the Tub Seal. Replace the Outer
Tub and Tub Seal. Inspect the Spinner Support for
damage around the Tub Seal area. Replace the
Spinner Support if it is damaged.
4. The Clutch Assem bly should be inspected for signs
of water or oil contamination. Clean Clutch
Assem bly as needed. Replace Clutch Assem bly
when water or oil contam inates the roller clutches.
Note: Oil in a new Transm ission is clear. During
operation, the oil will turn a dark color caused by the
special com pounds in som e of the bushings.
