Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
ok does this actually fill on its own? when you start the machine does the water go in and fill? or does it just buzz?
Okay sounds like the valve is bad, but before replacing that go under your sink and check the shutoff and make sure that somebody didn't accidentally shut the water off to the dishwasher, there will be a shutoff valve on the sink you'll see a copper line or possibly stainless steel line connecting to your hot water under the sink may sure that is turned on fully, if it is then need to replace a valve you can order it at the link below, for $29.20
link for part, thanks Bryan
What if it is not the inlet valve? I replaced it and it is still not moving on to the next cycle. I poured water in the dishwasher and it pumped it out however the cycle does not complete. The hoses are not bent and the water valve is on.
