If you have a washing machine that overfills, you don't have to buy a new one. It is possible to troubleshoot the problem. However, it should be fixed right away to avoid flooding. Here are tips to fix a washing machine that overfills.
Prepare to Work
For this project, you need:
- work gloves
- pressure tube (optional)
- water inlet valve (optional)
- pressure switch (optional)
To figure out if the problem if mechanical or electrical, let the machine fill half way with water. Press the control knob in and disconnect the power cord. If water keeps pouring in it, the problem is mechanical. If the water stops filling, it is an electrical issue
Inspect the Pressure Tube
Disconnect the power cord, and disconnect the screws on the access panel by rotating the screwdriver to the left. Raise the panel up to disconnect it. Look for a switch with a black or clear tube connected to it.
Detach the cover to the pressure switch. Pull the end off the tube. Clean the end of the tube and blow into the it. Resistance means the tube is clogged. Flush the tube out with tap water. Clean the port the tube goes into with a toothbrush or small paint brush and reconnect the tube. Plug in the washer and test it. If it fails, replace the tube.
Test the Pressure Switch
Blow in the switch, listening for one click followed by another click. Connect the power cord. Allow water to fill; and blow in the switch again. If the switch is good, the water will stop. Otherwise, replace the switch.
Disconnect the power cord, and remove the dial on the switch that sets load size. Disconnect the tube. Detach the screws on the switch. Some switches may be removed by hand. Attach the new switch, and reconnect the hose.
Replace the Water Inlet Valve
Unplug the washer. Turn off the hot and cold water valves, and remove the access panel.
Disconnect the sensor wire under the lid. Use the screwdriver to remove the clips or screws. Remove the cabinet by tilting it to the front and raising it up. Detach the water supply lines in the back of the machine, and absorb water with the towel.
Disconnect the two inlet valve wires, and loosen the screws to free the valve. Press the clamp on the valve and remove the hose. Attach the end of the new valve to the hose, and secure it to the clamp. Reconnect wires and screws.
Turn on water and power, and then test the machine. If you don't trust your skills or none of the repairs work, contact an appliance service.
