John Doe May 04, 2014 for Model Number mhwe400ww01 My Maytag washer mhwe400ww01 does not work properly and I want to check the pressure switch. It has 4 pins. How do I use my multimeter to test it and what values should I get?
1 Answer John, With the air tube disconnected, and the wires removed from the switch, you should have the following readings at the water level switch terminals : terminals 11 and 14 should have a "Open" circuit. terminals 21 to 22 should have a "Closed' circuit. When you reinstall the switch and fill the washer, or carefully pressurize the switch terminals 11 and 14 should have a "open circuit, terminals 21 to 24 and 26 should have a "closed" circuit, and terminals 21 to 22 should have a "open" circuit.

S.B.S. August 06, 2012 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.
1 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...
Joe July 20, 2011 for Model Number MHWE450WW00 Can the water level pressure switch be adjusted to increase the water level for wash & rinse cycles? I see there is an adjustment screw on the pressure switch, it was probably set at factory to a certain level, but washer only has one inch of water in drum when filled at start of cycle.
1 Answer Hi Joe. If Your washer water valve is OK, then check where the fill hoses are connected to the Water valve. There are screens in the water valve inlet that need to be cleaned. Use a bucket and flush out your hoses. If all of this turns well and there are no fault codes then you must be OK. Any front load washer will detect the "Load" in the tub and how much the motor has to work to turn the tub. If it is "empty", Then it is programmed not to use much water for energy consumption rates. This is all factory set by the manufacture per government guidelines. Years ago it was OK to set the pressure switch the way you desired, but now the screw is back filled with "red wax". If this seal is broken then you have forever voided your warranty. Your water valve part # is WPW10289387. The pressure switch is part # WPW10271610. Hope this helps. Thank you. Read More...
