Bosch Dishwasher Error Code dr:10

The dr:10 code on a Bosch dishwasher indicates a motor winding short circuit associated with a damaged or failed tachometer. The tachometer is a speed-sensing component on the circulation pump motor, and when it fails or sends an abnormal signal, the dishwasher stops the cycle and displays this code. Both the tachometer and the motor windings need to be evaluated, along with the connecting wire harness.

No, you should not continue running the dishwasher while the dr:10 code is active. The code indicates a motor winding short circuit condition, and running the appliance in this state could cause additional damage to the motor or control board. The dishwasher will typically stop mid-cycle anyway, as the control board halts operation when this fault is detected.

Repair costs vary depending on the failed component. If only the wire harness needs repair or a connector needs reseating, costs may be limited to a service call fee, typically in the range of $75 to $150. Tachometer or circulation pump motor replacement, including parts and labor, generally runs between $150 and $400 depending on the specific model and local labor rates. Getting a diagnostic assessment before authorizing parts replacement is the best way to avoid unnecessary expenses.

A knowledgeable DIYer can start by inspecting the wire harness for visible damage and reseating any loose connectors, which costs nothing and may resolve the issue if a connection has simply worked loose. If the harness checks out, testing the tachometer and motor windings requires a multimeter and some familiarity with appliance wiring. Replacing the circulation pump motor or tachometer involves working inside the dishwasher's base and is generally best handled by a technician if you are not comfortable with appliance repair.

A power reset may temporarily clear the code and allow the dishwasher to start, but if the underlying tachometer or motor fault is still present, the code will return, usually quickly once the motor begins running. Resetting is useful for confirming whether the fault is persistent or intermittent, but it does not repair the root cause and should not be relied on as a fix.
