How To Fix A Washing Machine That Won't Fill Properly

Inlet Hoses and Screens

Your washing machine will be connected to the household water supply through fill hoses. Usully 4-5 feet in length, they often have a plastic or wire mesh screen at the end of the hose that attaches to the faucet. This is to prevent sediment from entering the water inlet valve located on the back of your washing machine. This is to prevent sediment from entering the water inlet valve located on the back of your washing machine. If yours isn't filling (with either hot or cold water), you should first check the screens. Turn off the faucets and remove the fill hoses from the inlet valve. Check out the screens that are part of the inlet valve. Check out the screens that are part of the inlet valve, cleaning or replacing if necessary. To test the hoses for adequate pressure, place them into a tub or bucket and turn on the faucet. If the pressure isn't powerful enough, remove the hose from the faucet and inspect the screens for dirt acuumulation or damage, and clean or replace if necessary.

If everything with the screens and hoses seem fine, yet the water pressure is low, you may need to figure out how to increase the water pressure. You may need to consult a plumber.

Water Inlet Valve

The inlet valve's job is to supply hot and cold water for the wash and rinse with two solenoids that operate inlets for both the hot and cold water supply. The valve is controlled by the timer, electronic control, the water temperature/cycle selector and the water level/pressure switch. If your washer is not filling with either hot or cold water and you have pressure to the inlet valve, you will now need to check that you have power to the solenoid on the valve during the fill portion of the cycle. To do this, check with a multimeter or a voltage tester. This is a live voltage test and should be done with extreme care by a qualified person. If there is power to the solenoid terminals, then the valve will need replacing as it is defective. If these is no power at the terminals, then it is one of the other components that is to blame, so it is best to check these also. If you cannot check for voltage at the valve, you can always check the solenoids for continuity with a multi meter. Make sure to turn off and remove the power supply to the machine before testing. If this has no continuity, then the solenoid is defective. Most commonly this part is not available to purchase separately, so unfortunately you will need to replace the complete valve.

Selector Switch and Water Temperature Switch

The selector switch or the water temperature switch selects the water temperature and the rinse portions of the cycle. This means the switch provides a circuit to supply power to the solenoids on the water inlet valve. Obviously, this will cause your machine to be unable to fill with water. If there is no power at the solenoids on the water inlet valve, then it could be the fault of the selector/water temperature switch. However, this can easily be tested for continuity with a multi meter. If you're unsure which wires need testing for this particular component, check the wiring diagram to determine the terminals you need to check. Most importantly, make sure you disconnect all power from the appliance before attempting this.

Water Level Pressure Switch

The water level switch is a pressure activated switch that is part of the water inlet valve circuit. It is normally located behind the control panel and has a hose or air dome tube that connects it to the tub. For washers that use an electronic control, this switch may be located at the sump area below the tub. If this part fails, then it may not be able to supply power to the water inlet valve. However, it is easy to check with a multimeter to see if there is still continuity. Again, you can check on the wiring diagram to determine which terminals to check for the particular part. As well, always make sure the power is disconnected before attempting these kinds of repairs.


Your machine's timer has the job of determining when the water inlet valve receives power to start filling the washer. The timer will have a series of electrical contacts that are operated by a small motor and cams. During the wash, these contacts will control the fill and rinse portions of the cycle through supplying power to the water inlet valve. To see if it is this part that could be messing with your dishwasher, check continuity with a multi meter. You will most likely need the electrical schematic to determine the correct terminals you will need to test. Always make sure to disconnect all power to the machine before attempting any of this.
