Maytag Dishwasher won't fill

If your Maytag dishwasher won't fill, start with the most common cause: a bad or clogged water inlet valve. When the water inlet valve fails, the dishwasher not filling with water usually comes down to the valve not opening, and it needs to be replaced since it is not repairable. Next, check the safety float in the tub for anything lodged underneath it, because a stuck float can make the dishwasher think the water level is already too high. After that, confirm the water supply shut-off valve under the sink is fully open. If those checks do not fix the problem, test the float switch, which can shut off power to the inlet valve if it is stuck or defective. Less often, the issue is electronic, with the main control board or control board failing to send power to the valve. For a Maytag dishwasher that won't fill, no water reaches the tub, or fills slowly, matching the exact part matters. Enter your model number on RepairClinic.com to find the correct Maytag water inlet valve, float switch, main control board, or control board for your specific dishwasher.

01 - Maytag 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 - Maytag 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 - Maytag 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.
