Bosch Dishwasher Error Code dr:07

The dr:07 code means the dishwasher has detected a failure in the motor control inverter or a short circuit in the wash motor. The inverter is the electronic module that controls motor speed and operation. The machine stops the cycle automatically to prevent further electrical or mechanical damage. Diagnostic test P4 is used to pinpoint whether the inverter, the motor, or the wiring between them is at fault.

No, you should not continue operating the dishwasher while dr:07 is active. The code indicates a potential short circuit or inverter failure, and running the machine in this condition could cause additional electrical damage or create a fire hazard. Leave the dishwasher off until the fault is diagnosed and repaired.

Repair costs depend on which component has failed. Replacing a wash motor typically ranges from $150 to $350 in parts and labor, while a motor control inverter replacement can range from $100 to $300 depending on the model. If both components need replacement due to a cascading failure, total costs could be higher. Getting a diagnostic assessment first helps avoid replacing parts that are still functional.

Some causes, like a jammed impeller or a loose wiring connector, can be addressed without special tools. However, replacing the motor control inverter or the wash motor involves working with high-voltage components and requires disassembling the dishwasher. Running diagnostic test P4 first helps identify the specific faulty component, but most repairs beyond basic checks are best handled by a qualified technician.

A reset may temporarily clear the code, but if the underlying motor or inverter fault is still present, dr:07 will return once the dishwasher attempts to run the motor again. Resetting is useful for ruling out a one-time control glitch, but it does not fix a failed inverter board or a shorted motor. Proper diagnosis using test P4 is necessary to confirm whether a reset is sufficient.
