Maytag Dishwasher F5E1 Error Code
Float switch open—suds or overflow path
What this error means
F5E1 means the float switch circuit read open when the control expected continuity. Suds overflow or a stuck float can trigger this safety code.
How F5E1 is detected
Maytag dishwasher models lock the door or lid before energizing fill, heat, or high-speed spin. F5E1 means the latch switch never sent a "locked" signal to the main control, or the lock motor did not complete its travel. On Maytag MDB4949SKZ, Maytag MDB7759AWM, and similar variants, clothing caught in the gasket, a misaligned strike, or a failed latch assembly are the most common mechanical causes—not the board itself.
Inspect the door gasket perimeter and strike alignment before replacing the latch. Excess suds lifting the float in the pan is reported frequently on this code. After correcting mechanical issues, use only dishwasher-specific detergent at the marked fill line. If the latch clicks but F5E1 persists, the door lock switch or wiring harness to the control board likely needs testing with a multimeter.
Do not force the door open during an active cycle; wait for the lock to release when the board de-energizes the lock motor—usually two to three minutes after canceling power on most Maytag units.
Common causes
- Excess suds lifting the float in the pan
- Float stuck in the up position from debris
- Open wire to the float switch
- Actual water in the base pan from a hose leak
Step-by-step fixes
- 1Use only dishwasher-specific detergent at the marked fill line
- 2Remove the toe kick and check the float moves freely down
- 3Dry any water in the base pan with towels
- 4Run a rinse cycle after clearing suds
When to call a technician
Water returns to the pan after drying—find the leak at inlet valve, door gasket, or pump seal before resetting.
Affected models
- Maytag MDB4949SKZ
- Maytag MDB7759AWM
- Maytag MDB8989SHZ
Prevention & maintenance
- Wipe the door gasket weekly and avoid overloading items against the seal—F5E1 often starts as a slow leak or latch misalignment.
- Record when F5E1 appears in the cycle and whether it clears after a 60-second power reset on your Maytag dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F5E1; Maytag uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F5E1; reversed plugs on pumps and valves cause immediate repeat faults.
