Water Level Pressure Switch

The water level switch is a pressure activated switch that is part of the water inlet valve circuit. This part is normally located behind the control panel and will have a hose or air dome tube that connects it to the tub. On washers that use an electronic control, this switch may be located at the sump area below the tub. If the switch is defective, it may not supply power to the water inlet valve. You can check the pressure switch for continuity with a multi-meter. You may need the wiring diagram for the washer to determine which terminals to check on the switch. Remove power from the appliance before performing this test.
