This is a water inlet valve which is used in some washing machines. The water valve controls and monitors the flow of water into the washer. It is used to supply cold, warm or hot water to the washer’s tub.
If you have noticed that your washer takes longer than usual to fill with water, your washer does not have cold water, hot water or very little to no water, maybe you even hear a humming or buzzing sound coming from the washer console, then these are all symptoms of a bad water inlet valve, but not always.
Always unplug the washer and turn off both hot and cold water valves from the household water supply before removing the supply hoses.
Before replacing the inlet valve or other washer parts you can check these items first. You will need to turn off the water supply to the washer. You will also need to check the filter screens in the water valve inlet ports as well as the filter screens in both of the water supply hoses, if any are present. It could be they are full of sediment or calcium deposits from hard water, preventing the water flow.
If this easy washer repair tip did not solve your washer, little to no water issue, then you will need to delve a little deeper and do some trouble shooting which will require a multi-meter or voltage tester. This will need to be performed by a person qualified to do this testing.
