If your Inglis 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, which can keep the dishwasher from filling with water at all. 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. After that, make sure the water supply shut-off valve under the sink is fully open. If those items check out, the problem could be a faulty float switch, a failed main control board, or a bad control board that is not sending power to the water inlet valve. For an Inglis dishwasher not filling with water, these are the parts and conditions most often behind a dishwasher no water complaint.

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.

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 - Inglis 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.
