Samsung Dishwasher Error Code 9C

The 9C code indicates a circulation pump fault. It means the dishwasher has detected that the pump is not operating correctly, either because a foreign object has jammed the pump impeller or because the Main PBA or Inverter PBA has failed. The dishwasher will stop mid-cycle and will not resume washing until the underlying issue is resolved.

A reset may temporarily clear the code, but it will return immediately during the next cycle if the underlying problem has not been fixed. The code is triggered by a real mechanical or electrical fault, not a software glitch. Resetting without addressing the root cause will not restore normal operation.

Repair costs vary depending on the cause. If a foreign object is cleared manually, the cost can be minimal. Replacing an Inverter PBA or Main PBA typically runs in the range of $100 to $300 or more for parts alone, with additional labor costs if you use a technician. A full circulation pump replacement can fall in a similar or higher range depending on parts availability.

In many cases, yes. If a foreign object is the cause, you can resolve it yourself by removing the lower spray arm and filter assembly and clearing any debris from the pump inlet area. However, if the impeller spins freely and the code persists, the repair involves board-level diagnostics and component replacement, which is better suited to a technician with experience in dishwasher electrical systems.

No, you should not run the dishwasher while the 9C code is active. The pump is not functioning correctly, which means water is not circulating as designed. Continuing to operate the unit could cause further damage to the pump motor or the control boards, and dishes will not be cleaned properly.
