Westinghouse SB921WG dishwasher leaking even when not in use.

Check the outlet pipe is not syphoning.
If it is up above the drum height and free to the air, check for a foreign body, sand etc, in the water inlet solenoid.

The hose that goes to the water dispenser most likely has a crack in it somewhere inside the door. Usually the heat from the light in the door deteroriates the hose and lets water leak inside the door every time the dispenser is used.

Not familiar with this particular model but the indication is for water in the very bottom of your unit. Either due to a leak or a faulty switch. A quick leak check is to tip your unit to the side and see if water dribbles out of the bottom. Side needs to come off and either find and fix the leak or replace the switch itself. If its just a leak and you tip the water out it will actually work till the leak fills up again.

Sounds like the seal has gone

1. Is your drain point higher than the bottom of the dishwasher? (ie, does it drain into the garbage disposer or does the drain line drop down below the floor into house plumbing?) Did you just install the unit? You may have to install an "air gap" to prevent syphoning.

2. Did the dishwasher work then suddenly stop working? (asking for clarification)

The water that is produced during a refrigerator's defrost cycle drains into a catch basin behind the interior wall of the unit. The water then drains into a tube which carries the water underneath the refrigerator to a drain pan, where it is evaporated by heat from the coils and the compressor. You should be able to see this tube at the back of the refrigerator.

If any part of this drain system gets blocked, the water is diverted before it reaches the drain pan. It sounds like you have such a blockage. In some refrigerators, you can pull this tube loose at the point where it connects with the catch basin. Blow into the tube and see if it is open. If it is, the blockage is likely in the catch basin inside.

There are 4 screws holding that kick plate on. Normally, they're 1/4" drive. Lay on the floor with a flashlight and look at all 4 corners (between the kick plate and the door and near the floor).

This is how to get the panel off, but without a make and model I can't help any further. If you could provide those, we can figure out how to repair the leak. Just let me know, OK?

most likely if your dishwasher fills and then stops with clean water still inside and hasent drained your problem is most likely your pressure switch is sensing an over fill situation possibly a blockage in the pressure switch hose or split in pressure switch hose or a faulty pressure switch.
