The Water Inlet Valve on your washing machine is used to fill the tub with cold, warm or hot water for the wash and rinse cycles. The valve is operated by electric solenoids that are controlled by the timer or electronic control board and the water level control/water level selector switch or pressure switch. If your washer continues to fill during a cycle, the water inlet valve could be at fault. To verify that the valve is at fault, unplug the washer when the symptom occurs. If the washer continues to fill, then the water inlet valve is defective. If the washer stops filling, then the problem is related to the electrical circuit that controls the valve.

    The water level switch is a pressure activated switch that is used to determine the correct water level in the tub. 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. As the water fills in the tub it will compress the air in the tube and push against a diaphragm inside the switch. The switch will control the water inlet valve and turn the valve off at the correct water level. If the tube has a leak or is plugged, not enough pressure may be created to activate the switch and the washer may overfill. If the switch is defective it may also cause the machine to overfill.

    To determine if the switch is bad, you should first eliminate the air dome hose as a problem. Look for signs of cracks or worn areas on the hose. Remove the hose and submerge in water. Seal one end and blow air into the other end and look for bubbles. Check for an obstruction in the hose as well. If the air dome hose appears to be ok, then the water level pressure switch may be defective. Inspect the switch for signs of a mechanical defect or debris plugging the hole in the inlet nipple. To test the switch contacts for continuity with a multi-meter, you will need to apply the proper amount of air pressure to the air dome tube and then look for the switch to go open circuit at that level. The easiest way to do this is to start the washer and allow it to fill to the normal level and then remove the power cord. Locate the pressure switch and remove the wires from the correct terminals and then perform the continuity test. There should be infinite resistance or an “open circuit” when the water level is correct. If not, then the switch is defective.
