Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
you should check your drain pump trap first thing. this code is an overflow condition.
If the Overflow contact on the pressure switch is Closed for more than 60 seconds and 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.
yes thats what it sounds like. this happens sometimes. good job and glad you got it running . thanks and best wishes, Bryan.
you can get a product called afresh at you local store to help get rid of the odor.
