Filling when not in use

Most Likely Causes

Washing Machine Water Inlet Valve

Most common causeappliancepartspros

The water inlet valve in a washing machine is responsible for allowing water to enter the appliance. If this valve is not closing it can cause the unit to fill when not in use. The water inlet valve requires a minimum water pressure of 20 psi. If the water pressure is sufficient and the issue persists, it is recommended to replace the water inlet valve.

Repair Steps

1.Shut off water supply. Turn off the valves where the water lines attach to the washing machine. This prevents flooding during repairs.
2.Release water pressure. Run the wash cycle to drain any remaining water trapped in the lines before proceeding.
3.Disconnect hoses. Detach the hot and cold water hoses from the valve itself using pliers if necessary.
4.Remove mounting hardware. Use a screwdriver to take out any screws or bolts attaching the inlet valve to the machine.
5.Extract old valve. Ease the inlet valve out of position once it is fully detached from mountings and water lines.
6.Inspect seal rings. If the rubber seal rings inside the valve port are cracked or deteriorated, replace them now.
7.Install new valve. Position the replacement inlet valve where the old one sat, aligning holes for mounting hardware.
8.Reattach securely. Replace all mounting bolts or screws removed earlier to fasten the new valve firmly in place.
9.Reconnect water lines. Attach the hot and cold water supply hoses to the new inlet valve ports using pliers if needed.
10.Restore water supply. Turn on valves to refill lines and test connections for leaks before operating.

Low Water Pressure from House Supply

If the water pressure going to the water inlet valve is too low, it can cause some issues. The water inlet valve needs a minimum pressure of 20 psi to shut off properly. When the valve doesn't receive enough pressure, it may not completely close after the power is turned off causing water to leak into the washer when it's not being used. If you notice low water pressure in all the faucets at your home, it's advisable to contact your local water supplier. They can help determine if the water pressure is sufficient and make any necessary adjustments if needed.

Clogged Screens in Fill Hose or Water Inlet Valve

Clogged screens in the valve can keep the water valves from closing. In some cases, additional screens may also be present in the hose washers/gaskets where the fill hose connects to the home's hot or cold shut-off valve. These screens provide extra protection and easier access for maintenance. It is important to periodically check and clean these screens in both the water valve and hoses if necessary. Here's how: Unplug the machine and turn off the water supply valves. Prepare a bucket to catch any remaining water in the hoses. Unscrew the hoses from the machine and inspect the filter for any blockages. Cleaning the filter is often sufficient to resolve the issue of the washer filling when not in use.
