How do you replace the water inlet valve on the estate by whirlpool

It depends on how deep you want to go with troubleshooting. The inlet valves are electrically controlled and it could be the valve that failed or the control board. Could be a loose connection. Whirlpool WPW10144820 Water Inlet Valve Assembly - AppliancePartsPros.com

bad inlet valve or water temperature switch

Check the water inlet valve (the part the hoses connect to) to see if it's letting water in while the machine is off.

Verify water flow to BOTH hot and cold inlet valves. Dirt can plug screens and Dad sometimes turns off water, trying to save $$. BOTH inlet valves need water flow.

Turn the washer on and let the water run, while the water is running unplug the power cord if the water stops the inlet valve is ok but if still running the valve is bad and need to be replace if the pump is good you need to test the water level switch, if faulty need to replace.
good luck

you probably have a clogged hose or a bad water inlet valve

Turu off the cold water to the m/c, and hold hose into a bucket or something similar, turn water back on again, and see if you have a supply, if water there, then check the filter i the valve it it has one, and clean if req'd, reconnect hose and try again, if still no cold fill ,then the inlet valve is probably faulty, you will need to replace same.

you need to replace the inlet valve something is stuck in the valve not allowing it to shut.

You either have a water inlet valve that is stuck open. Need to replace the valve. Give me the model # and I can be more helpful. thanks Dave www.washermd.com

Close your faucet valve on wall & unscrew your hoses to check screens on hoses & machine. Clean out well. See that the water pressure is good. Refit, check for leaks. If this is not the problem change your inlet valve, it is easily done.
