Maytag Washer Error Code F03/F04

F03/F04 indicates an accelerometer failure on the Central Control Unit. The accelerometer measures movement along the X, Y, and Z axes, and this code appears when all three axes report readings outside the normal range. The fault can result from a CCU that has come loose from its mounting or from an internally failed control board.

A reset may temporarily clear the code, but if the underlying cause has not been addressed, the fault will return once the washer resumes operation. The accelerometer continuously monitors movement during cycles, so a faulty or improperly mounted CCU will trigger the code again. Resolving the root cause is necessary before the error will stay cleared.

If the fix is simply reseating a loose CCU, there may be no parts cost, though a service call from a technician could run in the range of $75 to $150 for diagnostics and labor. If the CCU needs to be replaced, the total cost including parts and labor typically falls in the range of $200 to $450 depending on the specific model and local labor rates. Getting a diagnosis before ordering parts is advisable to confirm the CCU is the actual failed component.

The first step is to check whether the CCU has shifted or come loose from its mounting bracket, which requires accessing the control board area of the washer. If reseating the CCU and securing it to the mount resolves the issue, no parts are needed. If the fault persists after confirming proper mounting and inspecting all wiring connections, the CCU itself will likely need to be replaced, which is a more involved repair.

It is not recommended to continue using the washer while this fault is active. The accelerometer plays a role in detecting drum imbalance and managing spin speeds, so operating without reliable sensor data could allow unsafe spin conditions to go undetected. Addressing the fault before running additional cycles is the safer approach.
