Bosch Washer Error Code dr:08

The dr:08 code means the washer's motor speed sensor has failed or is sending no usable signal to the control board. The control board relies on this sensor to monitor and regulate motor speed throughout each wash cycle. The fault can come from the sensor itself or from the wire harness connecting it to the board. The machine will typically stop the cycle until the issue is resolved.

It is not recommended to continue running the washer while dr:08 is active. Without accurate motor speed feedback, the control board cannot properly regulate the motor, which could lead to over-spinning, mechanical stress, or damage to other components. The washer will usually stop the cycle automatically when this fault is detected, which is a protective measure.

A power reset may temporarily clear the code from the display, but the fault will return as soon as the washer attempts to run the motor and the control board detects the same missing or invalid speed sensor signal. A reset does not repair the underlying hardware problem. Clearing the code permanently requires diagnosing and correcting the actual fault in the sensor or its wiring circuit.

Some aspects of this repair are DIY-accessible, such as inspecting the wire harness for visible damage and firmly reseating any loose connectors in the motor speed sensor circuit. However, properly diagnosing the fault requires running Bosch's test P4 diagnostic routine, which requires familiarity with service mode procedures. Replacing the sensor or harness also involves accessing internal components, so comfort with appliance disassembly is necessary.

Repair costs vary depending on the root cause. If only the wire harness needs repair or a connector needs reseating, costs could be minimal, primarily covering labor. A replacement speed sensor typically adds parts costs in the range of $20 to $80. If the control board is at fault, total repair costs including parts and labor could range from $200 to $450 or more depending on the model and service rates in your area.
