Samsung Dishwasher Error Code 5C2

The 5C2 code means the dishwasher detected a drain pump error 11 consecutive times, with 5-minute pauses between retry attempts. After the third pause-and-retry cycle fails, the drive components stop to protect the appliance. This code specifically points to a failure in the Inverter PBA, which is the circuit board that controls the drain pump motor.

No, you should not continue running the dishwasher after this code appears. The control system has already shut down the drive components after repeated failures, meaning the appliance cannot complete a drain cycle. Running it in this state risks water remaining in the tub and potential secondary damage.

A power reset may temporarily clear the displayed code, but it will not resolve the underlying Inverter PBA issue. Because the 5C2 code only triggers after 11 failed drain attempts across multiple retry cycles, the fault is persistent and will return as soon as the dishwasher tries to drain again. A proper repair of the root cause is required to resolve it permanently.

Some preliminary checks are DIY-friendly, including inspecting the drain pump area for blockages and examining wiring connections to the Inverter PBA. However, diagnosing and replacing the Inverter PBA itself involves working with electrical components and typically requires disassembly of the dishwasher, so most homeowners should consider a qualified technician for that step.

Repair costs vary depending on whether the Inverter PBA or another component is at fault. Parts costs for a replacement Inverter PBA typically range from around $80 to $200, and professional labor can add another $100 to $200 depending on your location and the service provider. A full repair bill generally falls somewhere in the range of $150 to $400.
