Kenmore Elite HE 3T front load washer

Hope this helps ...... F09 is a 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 PLEASE rate my solution
