unexpected water levels.

Customer complains of unexpected water levels.

A. Verify the complaint with the following procedure by checking for proper water level fills.
Use the table below:
WATER LEVEL SELECTION
If the complaint is not verified, do the Pressure Transducer/Agitator Test in the Service Diag-
nostic Test Table. Note the results of the first steps and the third from the last step of the
routine.

If the complaint is verified:

B. Check that the hose connections between the pressure transducer in the console and the
pressure dome attached to the tub are OK. If they are, do the following test:
1.
With AC power on and the tub empty, measure the DC voltage between pins P1-1 and P1-2
while the connector is still attached to the control board.
2.
If the voltage is between 2 and 3 VDC, replace the control board. If the voltage is outside of
this range, check the harness connnections.
3.
If these connections are OK, replace the water level transducer.

Perform the same procedures as described in B above.
Test #8 - Recirculation Pressure Switch Test
Perform Recirculation Pressure Switch Test in the Service Diagnostic Test table.
1.
If water recirculation does not take place, do the following test:
2.
Connect a voltmeter (set to measure AC volts) across P5-4 and P5-2. At the times in the
service diagnostic routine where recirculation should take place, the AC voltage reading should
go from a reading of about 120 VAC down to about 0 VAC.
3.
If this does not happen, replce the drain/recirculation pressure switch. NOTE: When the tub is
empty, the drain/recirculation pressure switch is closed and line voltage (125 VAC) must be
measured across P5-4 and P5-2. If test fails, replace the drain/recirculation pressure switch.
4.
If test shows that the drain/recirculation pressure switch is OK, the problem is either in the
electronic control board or the drain/recirculation solenoid valve.
Unlike other solenoids, the coil resistance in the drain/recirculation solenoid valve can not
be measured. Replace the solenoid.
If the washer still does not recirculate, replace the electronic control board.
