It was working just fine, then suddenly the hot water will not run into the washer. Cold water does, and all the hot water in the rest of the house is fine. Thanks for your opinions!
The first thing to do is remove the hot water hose from the back and place it in a bucket. Turn on the water to see if it’s going in there hot. The next step is to clean the filter on the inlet valve while the hose is off. If the water is hot and the hose inlet screen is clear, then it’s the inlet valve that will need replacing.
