Machine is flashing F09 and it doesn't tumble

F9 is an Overflow Condition error. 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 may remain locked, and the Drain Pump may run constantly, even if PAUSE/CANCEL is pressed twice and the Display is cleared. Unplug the unit to service. You will need to check to following:

1. Check the drain hose and make sure it is not plugged or kinked.
2. Check Wire Harness connectors to the Drain Pump, Pressure Switch, and Central Control Unit (CCU).
3. Check/Clean Drain Pump Filter of foreign objects
4. Check for Drain Pump Failure.
5. Check the Inlet Valve for proper shut off
6. Check the Pressure switch for proper operation
