Whirlpool F09

What it means

Overflow Condition (Pressure Switch Closed Too Long).

How to fix it

1. Check to make sure drain hose is not plugged or kinked and unplug the unit and disconnect power. Check wire harness connections to pressure switch, drain pump, and Central Control Unit (CCU). Check for drain pump failure and clean it of any debris. Check the inlet valve and pressure switch for proper shut off and operation. Replace failed component. Note: If this error occurs, the door will remain locked and the drain pump will run constantly even if 'cancel' is selected. Turn off hot and cold water to faucets and unplug the unit before proceeding.
