DO NOT REMOVE OR DESTROY
6. Unplug washer or disconnect power.
7. Reassemble all parts and panels.
8. Perform the Service Test Cycle
on page 5 to verify repairs.
TEST #6: Water Level Sensor
This test checks the water level sensor, ACU,
and wiring. NOTE: Usually, if the water level
sensor malfunctions, the washer will generate
a water level sensor error (F36), long fill error
(F01), or long drain error (F03).
1. Check the functionality of the water level
sensor by running a small load cycle. The
valve should turn off automatically after
sensing the correct water level in the tub.
The following steps assume that this step
was unsuccessful.
2. Press START/PAUSE to stop the cycle and
then press POWER. The cycle will cancel and
drain the water from the tub.
3. Unplug washer or disconnect power.
4. Remove top and rear panels to access
tub, air trap, and pressure hose connections.
Water level sensor is located at top right front
of cabinet.
5. Check connections from tub to air trap,
air trap to pressure hose, and pressure hose
to water level sensor.
6. Check to ensure hose is routed correctly in
the lower cabinet and not pinched or crimped.

7. Verify there is no water, suds, or debris
in the hose or air trap. Disconnect hose from
water level sensor, clean air trap and remove
and blow into hose to clear water, suds,
or debris.
8. Check hose for leaks. Replace if needed.
9. Visually check that connector J21 is
inserted all the way into the ACU. Also check
that the water level sensor harness is securely
connected to the sensor.
10. Check the harness between the ACU and
water level sensor for continuity.
If there is continuity, go to step 11.
If there is no continuity, repair or replace
as necessary.
11. Plug in washer or reconnect power.
12. With a voltmeter set to DC, connect black
probe to ACU connector J21, pin 6 (GND) and
red probe to J21, pin 5 (+5V [Vcc]).
If +5V DC is present, replace the water
level sensor. (Before replacing the sensor,
make sure that there is NO water remaining
in the tub or there will not be an accurate
water level measurement and an error code
may appear. Drain the tub by running a
drain & spin cycle with the sensor plugged
into J21 but with the hose removed).
If+5V DC is not present, perform TEST
#1: ACU Power Check on page 16.
13. If the preceding steps did not correct the
problem, replace the ACU.
Unplug washer or disconnect power.
Replace the ACU.
Reassemble all parts and panels.
Perform the Service Test Cycle
on page 5 to verify repair.
TEST #7: Drain Pump
Perform the following checks if washer does
not drain.
1. Check for obstructions in the usual areas.
Clean and then perform step 2.
2. Check the drain pump and electrical
connections by performing the Service Test
Cycle on page 5. The following procedures
assume that this step was unsuccessful.
3. Unplug washer or disconnect power.
