The F9 error code is indicating an 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 remains locked, and the drain pump runs constantly, even if PAUSE/CANCEL is pressed twice and the display is cleared. Turn off hot and cold water faucets and
the unit before servicing.
â€¢ Check the drain hose and make sure it is not plugged or kinked
â€¢ Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
â€¢ Check/ Clean Drain Pump Filter of foreign objects
â€¢ Check for Drain Pump Failure (see images for access and location) NOTE: I recommend calling a service technician if the pump is not clogged or restricted.
â€¢ Check the Inlet Valve for proper shut off
â€¢ Check the Pressure switch for proper operation
I recommend calling a service technician to diagnose and repair your washer.
