Maytag Dishwasher Won’t Fill with Water — What’s Happening
A Maytag dishwasher that won’t fill with water is experiencing an interrupted fill sequence. This is not an error code but a symptom that the machine is either being commanded to fill and water isn’t entering the tub, or a safety circuit is intentionally stopping the fill.
Common inhibit points include the water inlet valve, the overfill protection float, the door switch or latch, the household water supply, and the main control board. The machine may start its cycle but never progress past the fill stage, or it may not start at all if the door isn’t latched properly.
Most Likely Causes
- Closed or restricted water supply The household shutoff valve under the sink is closed, partially closed, or the fill hose is kinked.
- Stuck or obstructed overfill float The float is stuck in the raised position due to debris in the guide tube, holding the machine in a no-fill safety mode.
- Defective water inlet valve or clogged screen The valve is cracked, damaged, or its internal screen is blocked with sediment, preventing water from entering.
- Faulty float switch The switch that signals the float position is not changing state or is defective, so the control board thinks the tub is full.
- Door not latched or bad door switch The door isn’t fully closed or the interlock switch is faulty, so the cycle won’t begin or fill won’t start.
- Control board output problem The board is not sending voltage to the inlet valve during the fill cycle, even when all mechanical and supply checks pass.
How to Diagnose and Fix
- Verify the household water supply valve under the sink is fully open and the fill hose is not kinked or crushed.
- Lift and drop the overfill float inside the tub to confirm it moves freely up and down, and inspect the guide tube for debris or obstructions.
- Check that the door is fully closed and latched, and listen for the door switch click when you close it.
- Remove the water inlet valve from the supply line and inspect the internal screens for sediment or blockage.
- Test the float switch by pressing it down manually and checking for continuity change from open to closed with a multimeter.
- Disconnect power, then measure the inlet valve coil for an open circuit or visible damage such as cracks in the valve body.
- Restore power and use a multimeter to test for 120 volts at the inlet valve terminals during the fill portion of the cycle.
- If voltage is present at the valve but no water enters, replace the inlet valve. If voltage is absent and upstream switches test good, inspect wiring and the control board.

When to Call a Pro
Call a professional if you’ve confirmed the water supply is open and the float moves freely but the dishwasher still won’t fill, or if you’re uncomfortable working with 120-volt circuits during live testing. A technician can test the control board output, trace wiring faults, and confirm whether the board or valve is at fault when voltage and continuity readings are inconclusive.
