Maytag Washer Error Code d12

The d12 code indicates a motor sense error detected by the control board. It means the board cannot properly read the motor's operating feedback, either because of an internal board fault or because power line interference is corrupting the signal. The washer stops the cycle automatically when this error occurs to prevent further damage.

A reset may temporarily clear the d12 code, but if the underlying cause is still present, the error will return. To reset, unplug the washer for a few minutes and then restore power. If the code reappears during the next cycle, the root cause must be identified and corrected before the machine will operate reliably.

Repair costs vary depending on the root cause. If the issue is power line related and no parts are needed, costs may be limited to a service call fee, typically in the range of $75 to $150. Replacing a control board generally runs between $150 and $350 including parts and labor, while a drive motor replacement can range from $200 to $400 or more depending on the model and labor rates in your area.

Some causes of the d12 error, such as power line interference or a loose wiring connection, can be addressed without professional help. Check that the washer is on a stable, dedicated electrical circuit and inspect the motor harness connectors for corrosion or looseness. If the error persists after these checks, a faulty control board or drive motor will likely require a technician to diagnose and replace.

It is not recommended to continue using the washer while the d12 error is present. The code indicates the control board cannot properly monitor the motor, which could allow the motor to operate outside safe parameters. Running the machine in this condition risks further damage to the motor or control board.
