i had the same problem .code e 20 i checked hose found no problem .took the back off the washer and found the pump.tok it out and found a small allen wrench had the impeller jamed.
all my fault i am an industral mechanic ,i must have left it in my work uniform.there is a sump in front of the pump to catch coins and such but the wrench got through .cleared the jam ,washer works fine .SO CLEAN TOOLS OUT OF YOUR POCKETS.LOL oh and be careful the metal is sharp in there
