White-Westinghouse Dishwasher won't fill

If your White-Westinghouse 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 has to open for the dishwasher to fill with water. Next, check the safety float in the front corner of the tub. If something is stuck under it, the dishwasher may think it is already full and shut off the fill. After that, look at the main control board, make sure the water supply shut-off valve under the sink is fully on, and test the float switch for continuity. A faulty control board can also keep the water inlet valve from getting power. If your White-Westinghouse dishwasher is not filling with water, has no water, or fills slowly, these are the first components to inspect. Enter your model number on RepairClinic.com to find the exact White-Westinghouse water inlet valve, float switch, main control board, or control board that fits your specific dishwasher.

01 - White-Westinghouse 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 - White-Westinghouse 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.

05 - White-Westinghouse 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.
