KitchenAid Dishwasher won't fill

If your KitchenAid dishwasher won't fill, start with the parts and checks most likely to stop water from entering the tub. The first suspect is the water inlet valve. If the valve is clogged or electrically failed, your dishwasher not filling with water is almost guaranteed. Next, check the safety float in the front corner of the tub. If something is stuck under it, the float can signal an overfill condition and shut off the fill. After that, look at the main control board, which sends power to the water inlet valve, then confirm the water supply shut-off valve under the sink is fully open. A bad float switch can also keep a KitchenAid dishwasher from filling, and in some cases the control board itself is the problem. If your KitchenAid dishwasher won't fill, has no water, or fills slowly, these are the components to inspect first. RepairClinic.com makes it easier to match the right replacement part, whether you need a water inlet valve, float switch, or control board. Enter your model number to find the exact KitchenAid dishwasher part that fits your machine.

01 - KitchenAid Dishwasher Water Inlet Valve

The water inlet valve opens to allow water to enter the dishwasher. If the water valve is clogged or defective, water will not flow into the dishwasher. Water inlet valves are not repairable—if the valve is defective, you must replace it.

02 - Object stuck under the safety float

Some dishwashers have a safety float in the front corner of the tub to prevent the dishwasher from overfilling with water. If an object is stuck under the float, the dishwasher may not fill with water. If you find anything stuck under the float, remove it and the dishwasher should start filling properly.

03 - KitchenAid Dishwasher Main Control Board

A dishwasher's main control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the water inlet valve, preventing it from opening and allowing the necessary water to fill the tank.

04 - Water supply valve turned off

You should confirm that the dishwasher's water supply shut-off valve is in the "On" or open position. The water supply shut-off valve is usually located under the sink and is connected to the hot water line.

05 - KitchenAid Dishwasher Float Switch

The float switch is a safety designed to shut off the water inlet valve if the dishwasher is overfilling. If the float switch is defective or stuck, it might stop the dishwasher from filling correctly. You can use a multi meter to test the float switch for continuity. If the float switch is defective, replace it.
