I inherited a dishwasher with a house just bought. I tried to check out the dishwasher, but not working. I pulled it out of the cabinet. The motor is working but just won't fill up with water. I see a inlet valve underneath. Don't know how to check to see if it is indeed working. I have no manuals. Is there a float switch that may tie into it?

I actually pulled it out completely(disconnected and in garage). I have water running to it and power. I can hear the motor/pump running but no water going into it. Do you know where a float switch may be? Looking at a couple of other threads, there seems to be one, but can't locate.

I found the float. I ohm'd it out and works fine. I hooked up water and power again. I turned it to the normal wash. The motor kicked on, then after a few seconds(more than 20) the water valve opened and water started entering the dishwasher, but was coming out of the drain line. ODD. I barely got any water into the unit then the motor came on again. No water spraying inside. I got the water hose and filled it up to the float. Closed door and it started the wash cycle. There was constant water (slow flow) coming out of the hose. I held the hose up and it stopped. When it drained, it didn't fill up again. The valve opened again for maybe a minute, then stopped. I opened the door and barely any water. Everthing seemed to work.
