Bottom line: A Maytag dishwasher that will not fill (often showing F2E1) is usually a closed supply valve, a stuck float, or a clogged inlet-valve screen long before the valve itself has failed. Work the cheap checks first; the whole diagnosis and repair runs 20-40 minutes.
Disconnect power at the circuit breaker before testing electrical components. Turn off the water supply before disconnecting any water lines.

Step by step#
1. Confirm the water supply is on#
It sounds obvious, but a closed supply valve is the most common no-fill cause. Check the hot-water valve under the sink — fully open is the handle parallel to the pipe on a ball valve, or fully counter-clockwise on a gate valve. It is easy to leave shut after another repair.
2. Check the float switch#
The float is a small plastic disc on the tub floor that stops overfilling. If food debris or a fallen utensil jams it in the raised position, the board reads the tub as full and never opens the inlet valve. Lift it and confirm it moves freely.
3. Inspect the inlet valve screen#
In hard-water areas a clogged inlet-valve screen is the top mechanical cause. Cut power and water, remove the lower access panel (two 1/4 inch hex screws), find the valve where the supply line enters, and check the fine mesh screen for scale, cleaning it in vinegar.
4. Test the inlet valve solenoid#
If the screen is clear and the supply is confirmed but it still will not fill, test the solenoid. With power off, pull the wire harness and measure the coil — a healthy valve reads 500-1500 ohms, while an open circuit means the coil has failed.
5. Verify the board sends a fill signal#
If the valve tests good but never opens during a cycle, the board may not be sending voltage. This advanced check needs the unit powered: reconnect the harness, start a cycle, and carefully measure for 120V at the valve during the fill phase.
6. Replace the inlet valve#
With water and power off, unthread the supply line from the valve inlet with a wrench, squeeze the outlet-hose clamp and pull the hose, disconnect the harness, and remove the one or two mounting screws or clip. Fit the new valve in reverse.
7. Check for a kinked supply line#
Before closing up, confirm the supply line from the sink to the valve is not pinched. Pushing the dishwasher into the cabinet can crush the line against a wall or floor, restricting flow enough that the tub fills very slowly or not within the programmed window.
8. Test the full fill system#
Restore water and power and run a Normal cycle, watching the fill. You should hear the valve click open and water rush in, with fill taking about 90-120 seconds before the circulation pump sprays. A much longer fill points at marginal water pressure.
If it still won't fill#
- Fills but slowly now: almost always a scaling inlet-valve screen — soak it in vinegar.
- F2E1 with a good valve: low pressure below 20 PSI can exceed the 120-180 second timeout even with a working valve.
- Runs dry: the pump engages without water, but prolonged dry running can damage the pump seal, so fix the no-fill promptly.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

When to call a pro#
Measuring live voltage at the valve or chasing a board fault is best handed off if you are not comfortable with power on. See our dishwasher repair cost guide or book a same-day repair.
