21 codes documented for Maytag washers
The central control unit (CCU) has detected an EEPROM disconnect or memory corruption. The washer cannot execute its stored cycle programs. Power cycle the washer by unplugging for 60 seconds. If F01 returns, the main electronic control board requires replacement.
The motor control unit (MCU) has experienced an internal fault or is not communicating with the central control unit. The washer drum will not spin or agitate. Check the wiring harness between the MCU and CCU. If connections are secure, the MCU board requires replacement.
The washer did not detect water entering the tub within 6 minutes. Verify that both hot and cold water supply faucets are fully open, check inlet hoses for kinks, and inspect the inlet valve screens for sediment buildup. If the water supply is confirmed adequate, the water inlet valve assembly has failed and requires replacement.
The washer is unable to drain water within the expected time. The drain pump filter may be clogged with lint, coins, or small objects. Check the drain hose for kinks and ensure the standpipe is not blocked. Clean the drain pump filter (located behind the lower access panel on front-load models). If the pump runs but water does not drain, the pump impeller may be damaged.
The door lock mechanism has failed after 6 consecutive attempts to lock. The washer will not start a cycle if the door cannot be confirmed locked. Inspect the door latch assembly for obstructions or damage. The door lock actuator motor or the door lock switch may have failed and require replacement.
The washer heating element is not functioning. The water temperature will not reach the selected setting, which can affect cleaning performance on hot-water cycles. The heating element has an open circuit or the temperature control circuitry on the main board has failed.
The water temperature sensor (NTC thermistor) is reading out of range. The washer cannot verify water temperature, and heated cycles may be disabled. The thermistor is typically located on or near the outer tub. Check the wiring connections first, then replace the sensor if readings are abnormal.
The drive motor tachometer (speed sensor) is not providing a valid signal. The motor control unit cannot regulate drum speed, which may cause the washer to stop mid-cycle or fail to spin. The tachometer is mounted on the drive motor. Inspect its wiring and connections. If damaged, the tachometer or entire motor assembly may need replacement.
The door switch is reporting an inconsistent state — the switch signal does not match the expected door position. This differs from F22 in that the switch itself is faulty rather than the lock mechanism. The door switch assembly requires replacement.
The washer has detected an overflow condition — water level has exceeded the maximum safe level. The drain pump will activate automatically. This can be caused by a stuck-open water inlet valve or a faulty pressure switch. Disconnect power immediately and inspect the inlet valve. Do not restart until the cause is identified.
The central control unit (CCU) and motor control unit (MCU) have lost serial communication. The washer cannot operate without this communication link. Check the wiring harness between the two boards for loose connections or damage. If wiring is intact, one or both control boards may need replacement.
The door lock mechanism was unable to unlock after the cycle completed. The door remains locked with laundry inside. Do not force the door open. Power cycle the washer and wait 5 minutes. If the door does not release, the door lock actuator has failed and requires replacement by a technician.
The detergent dispenser motor or the dispenser switching mechanism has failed. Detergent, bleach, or fabric softener may not be dispensed at the correct time during the wash cycle. Check for clogged dispenser compartments first. If the motor does not actuate, the dispenser assembly requires replacement.
The motor control unit (MCU) temperature has exceeded safe operating limits. The washer will shut down to prevent damage. This can be caused by overloading the washer, a seized drum bearing, or poor ventilation around the MCU. Allow the unit to cool, then restart. If the code recurs, the MCU or drive motor may need service.
The drain pump drive circuit on the main control board has failed. The pump motor is not receiving the correct voltage signal. This is distinct from a clogged drain (F21) — in this case, the pump itself cannot be energized. The main electronic control board typically requires replacement.
Items were detected in the drum when the Clean Washer cycle was started. The Clean Washer cycle uses high-temperature water and cleaning agents that can damage clothing. Remove all items from the drum and restart the Clean Washer cycle with an empty tub.
The washer has detected excessive suds in the drum. Too much detergent or the wrong type of detergent (non-HE) was used. The washer will extend the rinse cycle and may pause to allow suds to dissipate. Use only HE (High Efficiency) detergent and reduce the amount used. This is the most common Maytag washer error and is usually user-correctable.
The washer is taking too long to fill with water. Similar to F20 but triggered at a different threshold. Verify that both water supply faucets are fully open and that water pressure is adequate (minimum 20 psi). Check inlet hose screens for sediment. On top-load models, ensure the lid is fully closed as some models pause fill when the lid is open.
The top-load washer lid is not fully closed or the lid lock switch is not engaged. The washer will not start or will pause mid-cycle. Close the lid firmly until you hear it click. If the lid is closed but the error persists, the lid lock switch mechanism may be faulty and require replacement.
The washer motor is drawing excessive current, indicating the drum is overloaded with laundry. The motor protection circuit has engaged to prevent damage. Remove some items to reduce the load size and restart the cycle. Consistently overloading the washer can damage the drive motor, suspension springs, and bearings over time.
The door or lid lock mechanism has encountered a general lock or unlock failure. The washer detects a mismatch between the commanded lock state and the actual switch feedback. Inspect the door latch for obstructions. On front-load models, check that the door boot seal is not preventing full closure. The door lock assembly or wiring harness may require replacement.
