Bosch Dishwasher Error Code d:02

The d:02 code on a Bosch dishwasher indicates a motor control interruption, meaning the system has detected a fault in the motor control circuit. The dishwasher stops operation to prevent damage to the motor or control electronics. Diagnosis involves running the built-in test program P:04 to pinpoint the fault, and repair typically requires replacing the motor control module.

You should not attempt to run the dishwasher while the d:02 fault is active. The error indicates a breakdown in motor control, and continued operation could cause further damage to the motor, control board, or related wiring. Leave the unit powered off until the fault has been diagnosed and repaired.

Repair costs depend on whether the issue is a wiring fault or a failed motor control module. Wiring repairs are generally less expensive, while motor control module replacement parts and labor can range from around $150 to $400 or more depending on your region and the specific model. Getting a diagnostic estimate from a technician before authorizing parts replacement is advisable.

A DIYer with electrical knowledge can inspect the wiring harness and connectors between the motor control unit and the wash motor for visible damage, corrosion, or loose connections. However, running the diagnostic test P:04 and replacing the motor control module are steps that generally require familiarity with appliance electronics. If you are not comfortable working with appliance control circuitry, a qualified technician is recommended.

A power reset may temporarily clear the displayed code, but the d:02 fault will return if the underlying motor control problem has not been corrected. The fault is tied to a real hardware condition in the motor control circuit, so resetting without repair is not a lasting solution.
