Bosch Dishwasher Error Code C

Error code C on a Bosch dishwasher indicates a fault with the SIBRUSYM circulation motor, which is the pump motor responsible for moving water through the spray arms during a wash cycle. The dishwasher stops the cycle when this fault is detected to prevent further damage. The cause can range from a simple blockage in the pump to a failed motor or wiring issue. A technician will need to inspect the pump, motor, and related electrical components to pinpoint the exact problem.

No, you should not attempt to run the dishwasher while error code C is active. The appliance will generally not complete a cycle, and continuing to attempt operation with a faulty motor could worsen the damage or create electrical safety concerns. Leave the dishwasher powered off until the fault has been properly diagnosed and repaired.

Repair costs vary depending on the cause of the fault. Clearing a pump obstruction yourself costs nothing beyond your time, while professional labor for diagnosis and repair typically ranges from $100 to $200 or more. If the circulation motor or control board requires replacement, parts costs can add another $150 to $400 depending on the model. Getting a diagnostic quote from a technician before committing to the repair is advisable.

Some causes of error code C are DIY-accessible, such as removing debris or obstructions from the filter and pump area. However, tasks like testing motor windings, inspecting internal wiring connections, or replacing the circulation motor or control board typically require disassembly of the appliance and comfort with electrical testing. If you are not experienced with appliance repair, it is recommended to contact a qualified technician.

A power reset, such as unplugging the dishwasher for a few minutes or cycling the circuit breaker, may temporarily clear the error code display. However, if the underlying motor fault still exists, the code will return once the dishwasher attempts to run a cycle again. A reset alone does not repair the root cause, so the mechanical and electrical issue must be addressed.
