after getting a 'check outlet pipe' message and cleaning the pipe out draining the machine it worked for several washes but suddenly filled up a quarter of the way with water when left idle for 4 days
if connected to sink u bend raise the height of the pipe between the u bend and the washer to prevent back siphoning out of the sink into the washer. If you are connected to a stand pipe check inlet solenoid valve rubber is seating. change the whole solenoid unit. If hot and cold fill are both used turn off one of the taps see if the machine fills y/n then turn the first tap back on and the other off see if machine fills we are doing this to test BOTH solenoids (the hot and the cold) ignore this test if you ONLY have a cold fill going in
