How to Troubleshoot an LG Washer WM06242H Fill Valve

Disconnect power to the LG washing machine from power and turn off the water valves. Remove the hoses from the washing machine and clean the inlet screen in the hoses as well as inside the washer connection port. Debris in the water hoses or inlet screens can affect the performance of the fill valve.

Find the screws along the back edges of the washing machine and remove with a Philips screwdriver. Set the screws aside. Lift the back panel up and off the washing machine and set down carefully.

Find the fill valve, which is blue and gray, on the right side near the top where the hoses usually connect on the back of the washer. Look at the valve to see if the valve is damaged and needs to be replaced, as further troubleshooting is unnecessary if the valve clearly needs replacement. Contact LG for replacement and/or service.

Use a label to identify the two wires that connect the solenoids to the valve, and then disconnect the wires at the connector terminal. Note that if the wire terminals or the wire connectors are corroded, these parts will need to be replaced as well.

Test for continuity on each solenoid using an ohm meter. If there is no resistance on one or both of the solenoids, the valve is faulty and needs replacement.

Use a clean, damp cloth to clean the valve well and remove debris if there is ohm resistance and the valve seems otherwise functional. Cleaning the valve can help remove debris that blocks the valve from closing and causes malfunction.
