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?
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.
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.
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 W10289387. The pressure switch is part # W10271610. Hope this helps. Thank you.
