Maytag Dishwasher Error Codes
Maytag dishwashers share Whirlpool F-code logic with MDB and MDT series units for drain, fill, and heat faults.
General troubleshooting
Try these checks before opening a specific error code page—they resolve many Maytag dishwasher faults without parts.
- 1Clean filter and sump under lower spray arm
- 2Dry base pan if overfill fault latched
- 3Verify drain hose high loop under sink
- 4Run hot water at sink before starting a cycle
- 5Check that the unit is level front to back
Common symptoms
Owners often search for a code after noticing one of these issues on their Maytag dishwasher:
- F8E4 overfill with water in the base pan
- Dishes not drying when the heating element fails
- F9E1 slow fill at cycle start
- Chopper grinding noise at drain
- Door won't latch on MDB4949SKZ
All Maytag dishwasher error codes
| Code | What it means | Guide |
|---|---|---|
| F1E2 | Main control EEPROM memory faultF1E2 signals the main control failed an EEPROM integrity check at startup. Cycle logic and timing tables may be unreliable until the board is replaced. | View fix → |
| F2E1 | Stuck key on the touch panelF2E1 means the touch interface reports a key held down. The dishwasher will not respond to new commands until the stuck key state clears. | View fix → |
| F2E2 | User interface disconnected from controlF2E2 means the touch user interface lost communication with the main control board. Cycle selection and status feedback stop until the UI harness reconnects. | View fix → |
| F3E1 | Thermistor open or shortedF3E1 means the wash thermistor sent an invalid reading. The control cannot verify water temperature for heat steps and drying efficiency. | View fix → |
| F3E2 | Water pressure sensor faultF3E2 indicates the wash tank pressure sensor signal is missing or out of range. Fill volume and overflow protection depend on this airtight hose circuit. | View fix → |
| F4E1 | Optical water sensor faultF4E1 indicates the turbidity or optical water sensor failed self-check. Auto soil sensing cycles cannot adjust wash time without this input. | View fix → |
| F4E2 | Circulation pump motor errorF4E2 means the main wash circulation pump failed to start or report correct feedback. Dishes stay dirty when wash arms do not pressurize. | View fix → |
| F5E1 | Float switch open—suds or overflow pathF5E1 means the float switch circuit read open when the control expected continuity. Suds overflow or a stuck float can trigger this safety code. | View fix → |
| F5E2 | Door switch not detected closedF5E2 means the control never saw the door switch close. Maytag dishwashers block fill and heat until the latch confirms the door is sealed. | View fix → |
| F6E1 | Water inlet valve circuit faultF6E1 means the water inlet valve did not respond correctly when the control commanded fill. The tub may stay dry or fill very slowly. | View fix → |
| F6E2 | Communication error between control boardsF6E2 is a general communication failure between distributed boards—often the main control and the user interface or dispenser module. | View fix → |
| F7E1 | Turbidity sensor communication faultF7E1 is a communication-specific fault for the soil-sensing module—distinct from F4E1 optical failure. Auto cycles may default to maximum time. | View fix → |
| F7E2 | Heating element circuit faultF7E2 means the dishwasher could not heat water to the target temperature in time. Sanitize and heavy cycles depend on the metal tub heater under the sump. | View fix → |
| F8E2 | Diverter motor position faultF8E2 appears on Maytag models with a diverter motor that routes water between upper and lower spray zones. The control cannot confirm the diverter reached the commanded position. | View fix → |
| F8E4 | Water inlet flood or flow faultF8E4 on Maytag dishwashers reports a water inlet flood condition—the overfill float or flow sensor detected excess water entering or not draining during fill. Maytag stops the cycle to limit tub overflow. | View fix → |
| F9E2 | Detergent dispenser actuation faultF9E2 means the detergent dispenser did not open or report open when commanded. Main wash chemistry may be missing, leaving greasy dishes. | View fix → |
