HI. This will be the result of a failed inlet assembly. Use my procedure to confirm the damage. If the inlet proves to be functional, replace the main control device.
The water inlet valve can be identified by the water hoses connected to it at the back of the washer. Start by turning off the water supply at the valves on the wall. Disconnect both hoses from the back of the washer. Place the hoses into a bucket and turn them on to confirm that you are getting good water pressure and to clear out any debris from the line.
Inspect the filter screens on both the hoses and the inlet valve for debris build up. If you find any debris, clean it out. Use caution to avoid damaging the filter screens because the screens in the valve are not replaceable.
If debris was not present then proceed to the next step of testing the solenoids. Access to the valve may be easiest by opening the top or the back of the washer, depending upon make and model.
There are two wires connected to each solenoid on the water inlet valve. Label the wires and connections so that you can properly reconnect them later. The wires are connected with slip-on connectors. Firmly pull the connectors off of the terminals ( Be sure to not pull the wires). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If either is corroded they should be cleaned or replaced.
Use a multimeter to test for continuity. Set the multimeter to the ohms setting X1. Touch one probe to each terminal. A reading of infinity indicates a bad solenoid that must be replaced. Different brands and models will have various measurements, but the valve should show some resistance if it is functioning properly. Test the second one in the same way as the first.
- NOTE_ You will need to remove the top cover off of the unit to access the valves for the electronic test.
