or 3) unplug the machine.
After five (5) minutes of inactivity (user key presses)
in Service Mode, the machine will exit the Service
Mode and resume normal operations. Pressing the
Off key will completely exit Service Mode. If a cycle is
running, cancel the cycle. Pressing the Start/Pause
key while running a test will pause the individual test,
while remaining in Service Mode. A power loss during
Service Mode will cancel this mode.
Hose Reversal Detection and Correction
The washing machine has diagnostic features that
determine if the hoses are reversed on the first
complete cycle after power up. The control board
monitors water temperatures during the wash cycle.
The control system is capable of detecting hot and
cold water intake hose reversal and will change the fill
temperature as necessary after the first cycle.
The control system stores and retains hot and cold
water intake hose reversal information through a
power-down.
The system reverts to factory defaults for the cold and
hot water valves and cancels hose reversal detection
if a diagnostic code 28 has been logged in a cycle.
