Jenn Air Dishwasher won't fill

If your Jenn Air 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 failed or clogged water inlet valve, since this valve has to open for the dishwasher to fill with water at all. Next, check for something stuck under the safety float in the front corner of the tub, because a blocked float can make the machine think the water level is already too high. 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 bad control board can also keep the water inlet valve from getting power. If your Jenn Air dishwasher is not filling with water, has no water, or fills slowly, these are the first components to inspect. 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 part that fits your specific Jenn Air dishwasher.

01 - Jenn Air 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 - Jenn Air 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.

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 - Jenn Air 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.
