Service Test Mode
The washer control has a service test mode that can be utilized by the service technician in order to test
critical components and to access error codes. This test mode will help the service technician to quickly
identify failed or improper operation of washer components.
Caution: Testing is accomplished through built-in test procedures. Unplugging components for testing can
damage component connections.
The washer must be in idle mode (blue screen is blank), before entering the test mode. Idle mode occurs
when the washer has completed a cycle. If the cycle is interrupted, the washer will drain water when the
power is re-applied. The water level switch must reset BEFORE the test mode can be entered. If water
remains in the washer, manually drain the washer to reset the water level switch. A failed water level switch
can cause an inability to enter the test mode.
