Bosch Washer Error Code dr:12

The dr:12 code means the motor control system detected a high-current condition and shut the motor off to prevent damage. This is a protective fault triggered when the motor is overloaded or mechanically bound. It can be caused by a jammed drum, bad bearings, a seized pump, or a failing motor. A diagnostic test designated P4 is used to identify the specific source of the problem.

No, it is not safe to continue running the washer with an active dr:12 fault. The error exists specifically because the motor was drawing dangerously high current, and running it again without resolving the cause risks damaging the motor, motor control board, or wiring. Stop using the machine until the underlying binding or overload condition has been diagnosed and corrected.

Repair costs vary depending on the root cause. Clearing a drum obstruction or cleaning the pump filter is inexpensive, typically just a service call fee in the range of $75 to $150. Drum bearing replacement is more labor-intensive and can run from $200 to $400 or more. Motor or motor control board replacement generally falls in the range of $250 to $500 depending on parts and labor rates in your area.

Start by checking for any foreign objects lodged between the drum and the tub, and try rotating the drum by hand to feel for stiffness or grinding. If the drum moves freely and no obstruction is found, the next steps involve running diagnostic test P4 and inspecting the drain pump filter for blockages. If mechanical causes are ruled out, the motor or motor control board may need professional evaluation and replacement.

A reset may clear the fault code temporarily and allow the machine to start, but the error will return if the underlying cause has not been addressed. Because dr:12 is triggered by a real electrical or mechanical condition, simply resetting the machine does not fix the problem. Repeated resets while the fault persists can lead to further damage to the motor or control electronics.
