We have a Whirlpool Duet Washer with Error Code SUD, and sometimes F35.
We cleaned out the drain tray at the bottom front and removed money a screw etc. That worked for a while. The strange thing is that the problem in intermittent. Sometimes the washer works, sometimes we get the error codes. Sometimes re-arranging the load or taking out a heavy wet towel works. Today we took off the top and washed out the drain hose, and took off the internal drain hose that goes from the pump up - and cleaned that out. There was nothing stuck in there. We put it all back together and washer is giving the SUD error code.
Question: is that the pressure switch? Or something else.
Thank You.
