Maytag Dishwasher DWC7400AAW Will not fill with water or doesn't fill with water

This water level switch senses the dishwasher's tub float and controls the water inlet. Replacing a worn switch restores correct filling, helping prevent overfilling or dry cycles that can reduce cleaning performance. What it does:

• Monitors the float position to open/close the fill circuit at the proper water level
• Common symptoms: dishwasher won't fill or stops filling too soon
• May also cause continuous filling/overfill if contacts are stuck closed
• Intermittent operation can leave the tub underfilled and washing performance poor

What's included:

• 1 water level (float) switch

Install notes:

• Disconnect power and shut off the water supply before servicing
• Remove the toe/kick panel to access the switch near the float assembly under the tub
• Note wire positions; transfer connectors one at a time and secure the switch in its bracket
• The float moves freely and actuates the switch before reassembly and testing

This float controls your dishwasher's water level. As the tub fills, it rises to signal the float switch to shut off incoming water, helping prevent overfilling and leaks.

• Lifts with the water to actuate the float switch and stop filling
• Helps protect against overfilling and door leaks
• Replace if the float is cracked, deformed, waterlogged, or sticks in its well
• Symptoms can include: won't fill or stops filling early; overfilling or leaks at the door

• Disconnect power and shut off the water supply before servicing
• Remove the lower rack and locate the float in the tub floor
• Lift the old float straight up; clear any debris; seat the new float and free up-and-down movement
• Restore power and run a fill test to proper operation and check for leaks
