DIAGNOSTIC TEST PROGRAM

The Diagnostic Test Program is designed to be an aid for authorized service technicians to objectively
test the washer’s water fill valves, drain pump and the clutch/brake solenoid, drive motor, water level
sensor, lid switch, LEDs and rotary switches.  There are four tests in the program all accessed from
the control panel by following a specified entry sequence.  NOTE:  Check the Tech Sheet provided
with the washer for most recent test sequences.

Entry Sequence

The entry sequence to begin the Diagnostic Test Program is as follows:

1.
