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.
Machine must be in idle mode before entering a test. Idle mode occurs when the washer has completed a
cycle. If the cycle is interrupted, the washer will drain water when the power is reapplied. The water must be
emptied BEFORE the test mode can be entered. If water remains in the washer, manually drain the washer to
empty. A failed water level switch can cause an inability to enter the service test mode.
