My washing machine worked fine yesterday, but today no hot water come into the drum. What might cause this?

Hi Had110...

There is usually fine mesh hose washers (see picture) installed on most washing machines today. So here, start by shutting the water off to the unit and then remove the hoses and inspect the hose ends and the washing machine threaded fittings. See if the filter/washer is clogged. Use a flashlight and really look into the ends of the hoses and inside the washing machine valve where the hoses connected to it.

While you have the hoses off, purge the shutoffs (turn water on for a second or two)to clear any sediment in the shutoff(s) itself.

Let me know what you find there... ok?

Otherwise, has it been really really cold in your area? Any chance pipe is frozen?

Back to you...

Like mark said, screen is most likely your problem, or (frozen pipe, hopefully not) Please let us know either way. Im betting on screen.

Additionally: there are 2 or 3 such a screens: One on each side of the hose and on inside threads at your washing machine.
