Maytag Washer Error Code d11/F11

The d11/F11 code indicates a Motor Control Unit (MCU) failure on your Maytag washer. The MCU manages power delivery and speed control for the drive motor, and this code appears when it detects an internal fault, often related to a repeating under or overvoltage condition. The washer halts operation to protect the motor and associated components from further damage.

It is not recommended to continue running the washer while this code is active. The MCU fault can cause erratic motor behavior or allow damaging voltage conditions to persist, which could worsen the failure or cause additional component damage. Stop use until the fault is diagnosed and resolved.

Clearing the error code by unplugging the washer or performing a reset may temporarily remove the code from the display, but it will return if the underlying fault is still present. A reset is a useful first diagnostic step to confirm whether the fault is intermittent or persistent, but it is not a fix on its own. The wiring and MCU should be inspected after the reset to identify the actual cause.

Some causes of this error are DIY-accessible. Start by unplugging the washer, then inspect and reseat all wire harness connectors between the drive motor and the MCU, checking for corrosion or loose pins. If the wiring looks good and the error returns after clearing it, replacing the MCU board is typically the next step, which is a more involved repair that requires comfort working with appliance electronics.

Repair costs vary depending on the root cause. If the issue is simply loose wiring connections, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the MCU board itself needs replacement, parts and labor combined can run anywhere from $200 to $450 depending on the specific model and local labor rates. Replacing the drive motor, if that is the source, will generally fall in a similar or higher range.
