Kenmore dishwasher filling with water when not in use

check water solenoid

Hello

Water inlet valve is responsible for filling water in your dishwasher, when that goes bad either the dishwasher wont fill at all or will fill the water slowly. Please check the inlet screens and also try to clean the water lines for any clogs/obstructions. Please get back to me if you have any other questions.

That is exactly correct!

The fill cycle is a set time and not measured. Either your water pressure is low at the dishwasher or the screen on the fill valve is partially blocked keeping the correct amount of water from entering during the fill cycle.

the water inlet valve has a screen on the water line connection side. it may look clean but most likely the residues have entered the vaslve and is restricting how much water can enter the unit. most units need to have the water fill to just below the heating element.
the water should just touch the element. if it does, water is fine, then it might be a circulation problem with the water pump being plugged, check to see if the pump is plugged.

this is meant to happen

I am almost certain that your problem is the fill solenoid.

If it does not work, there will be no water entering your machine.

I would either remove it and test it or just replace it at this point.

Replace the water fill valve, it's leaking.

water valve is clogged try to turn your valve to dishwasher under sink

either
leaking valve - to check, turn water off and see if it still happens
or
if appliance is plumbed in to a spigot on the sink trap, then when you empty sink, some of the water finds its way into the dishwasher via the drain hose. to cure, take the drain hose as high as possible under the sink in a swan neck
