It could be your water inlet valve. It's the part your water is hooked up to. There will be an incoming water hose (from water line) attached to it, an outgoing water hose (where water travels from inlet valve to dishwasher) and the wires giving it power. You can try two things. Before you do both of them, shut your water off and disable the power coming into the diswasher (shut the breaker off or unplug it if you have it plugged in).

1. Take the inlet valve completely off the diswasher (disconnect water lines and wires) and take it apart. There will be a screen inside. It may have minerals or other deposits on it that is preventing waterflow and clogging up the screen. You can pry the screen out with a flat blade screwdriver, but be gentle as not to damage it. If it was clogged, or there was blockage, that may have been your problem. If it's not clogged up, put it back together and try the next test.

2. Disconnect the wires from the water inlet valve (you don't have to take the inlet valve off the dishwasher for this one). Use a continuity tester to make sure it's not defective. Touch one probe from the tester to one terminal on the water inlet valve and then touch the other probe on the tester to the other terminal on the inlet valve at the same time. If there is continuity, it's working. It sounds like it is functioning, as you are getting some water in the dishwasher. However, i have heard that inlet valves will pass continuity tests because the solenoids in the valve are actually faulty, and not that valve, so it will pass the test. So it may still need replacing. Fortunately, water inlet valves are only 15-20 bucks, so you can always try getting a new one, and they only take minutes to install. Just make sure the water's off and the power's disconnected before you do so.

Good luck!

I took apart the valve, cleaned it and put it back on. It still did not completely fill, so I ponied up the cash for a new one. The dishwasher works great - again!! Thanks for your help.
