When the machine is filling with water, either the wash or rinse cycles, the water won't shut off automatically. All other functions work properly. Is the problem in the water level switch or main control? There is a circuit board on the control panel and I don't know what it is for.

Have you figured out how to remove the housing around the machine?

It could be either the water level switch or the water valves. If the water valves get trash or scale in the holes on the diaphragm the water will stay on because the valves cannot close. Unplug unit and if water stays on it's the valves. Remove the valves and disassemble then soak the parts, except the solenoid coils, in vinegar and water for a couple of hours. Then clean out well with toothbrush making sure holes in diaphragm are clear. There are little brass pieces where a hole has been drilled in the diaphragms and these must be clear of all trash and scale. Make sure pin and spring are clean and can move freely in passage that is surrounded by solenoid coil and seat for pin is clean, too. You can buy rebuild kits if the pins are worn out along with diaphragm, but normally all you need do is clean everything.
The water level switch can jam, too. It has contacts that can weld shut and you would have to replace the switch, or the clear plastic hose can get stopped up or get a hole in it which will keep the water from shutting off because water pressure turns water off. Here is a manual to explain things: https://dl.dropbox.com/u/8010163/Und...c%20washer.pdf

Thank you for the reply. It was very helpful. The 3/16 pressure hose came off the pressure switch. Your information allowed me to make repairs.

I am glad you were able to fix it so easily. I'm sure it saved you some money.
