Whirlpool Dishwasher won't fill

If your Whirlpool dishwasher won't fill, start with the parts and checks most likely to stop water from entering the tub. The most common cause is a bad or clogged water inlet valve, since this valve opens to let water into the dishwasher and must be replaced if it fails. Next, check for something stuck under the safety float in the front corner of the tub, because a blocked float can make the dishwasher think it is already full. After that, look at the main control board, confirm the water supply shut-off valve under the sink is fully open, and test the float switch, which shuts off the water inlet valve if the unit senses an overfill condition. A faulty control board can also keep the valve from getting power. If your Whirlpool dishwasher is not filling with water, has dishwasher no water, or you suspect a dishwasher water inlet valve problem, these are the first areas to inspect. Enter your model number on RepairClinic.com to find the exact Whirlpool replacement part for your dishwasher, whether you need a water inlet valve, float switch, main control board, or control board.

01 - Whirlpool 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 - Whirlpool 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.
Highly Likely

05 - Whirlpool 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.
