Maytag Dishwasher Error Codes
16 error codes with causes and fixes
- F2E2User 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.
- F3E2Water 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.
- F4E2Circulation 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.
- F5E2Door 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.
- F6E2Communication error between control boardsF6E2 is a general communication failure between distributed boards—often the main control and the user interface or dispenser module.
- F7E2Heating 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.
- F8E2Diverter 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.
- F9E2Detergent dispenser actuation faultF9E2 means the detergent dispenser did not open or report open when commanded. Main wash chemistry may be missing, leaving greasy dishes.
- F1E2Main 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.
- F2E1Stuck 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.
- F3E1Thermistor open or shortedF3E1 means the wash thermistor sent an invalid reading. The control cannot verify water temperature for heat steps and drying efficiency.
- F4E1Optical water sensor faultF4E1 indicates the turbidity or optical water sensor failed self-check. Auto soil sensing cycles cannot adjust wash time without this input.
- F5E1Float 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.
- F6E1Water 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.
- F7E1Turbidity 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.
- F8E4Water in drip tray detectedF8 E4 on Maytag dishwashers (Whirlpool platform) triggers when water hits the base drip tray or the float switch faults—the unit drains and locks out wash.
