S.B.S. for Model Number MHWE450WW01 I frequently get an F20 error code (water inlet problem or insufficient water supply). The washer stops and I have to drain it, and then do a rinse and spin cycle. It seems to only happen when I have a medium-to-large size load. Small loads do not trigger the code. I have spoken to my local dealer and unfortunately this will not be a warrenty-covered repair. My husband is handy mechanically. Could you point us in the right direction? He has cleaned the screens on the inlet and we seem to have plenty of water pressure going to the machine.
Answer Hello, The F20 fault code is normally for a failed flow meter, but this one has no flow meter. In light of this information, the issue will either be the fault of either a bad pressure switch WPW10271610, or a bad main control WPW10326989. Read More...
