The washer control has a service test mode that can be utilized by the service technician in order to test
critical components. This test mode will help the service technician to quickly identify failed or improper
operation of certain washer components.
Machine must be in idle mode before entering test. Idle mode occurs when the washer has completed a
cycle.
To enter the service test mode, press simultaneously the

With no clothing in the tub, when placed in the HA test, the following occurs:
Weight sensing begins.
1.
Weight sensing ends, only the appropriate load light stays lit, and the display shows corresponding
2.
weight sensing data.
The load light will indicate load size. Adding additional dry clothing, (not water( will decrease the data number
as weight is increased. Data readouts are approximate: Extra Small = 97, Small = 89-96, Medium = 82-88,
Large = 76-81, and Extra Large = 75 or lower.
If the Soak light remains lit, 100 will be added to the display number.
