F09 code has started appearing

Dale Fyman, F09 is Overflow Condition

If the Overflow contact on the pressure switch is Closed for more than 60 seconds

an Overflow condition will occur. In an Overflow condition, the Door will remain

locked, and the Drain Pump will run constantly, even if PAUSE/CANCEL is pressed

twice and the Display is cleared. Unplug the unit to service.

Potential Causes

• Check the drain hose and make sure it is not plugged or kinked

• Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)

• Check/ Clean Drain Pump Filter of foreign objects

• Check for Drain Pump Failure

• Check the Inlet Valve for proper shut off

• Check the Pressure switch for proper operation
