Samsung Dishwasher Error Code 5C5

The 5C5 code means the dishwasher detected a drain pump error 11 consecutive times, with 5-minute pauses and automatic retries between each attempt. After the third pause cycle, the driving components shut down to protect the appliance. Samsung's diagnostic data identifies an Inverter PBA failure as the indicated cause of this error pattern.

You should not continue running the dishwasher with an active 5C5 error. The appliance has already halted its drain components after repeated failures, meaning standing water may remain in the tub. Running additional cycles without resolving the fault risks water damage and could worsen the underlying board or pump damage.

A power reset may temporarily clear the error display, but the 5C5 code will return if the underlying fault is not corrected. Because the error only appears after 11 failed drain attempts across multiple retry cycles, a reset without fixing the Inverter PBA or drain system will result in the same failure sequence repeating during the next wash cycle.

Some preliminary checks are within reach for a confident DIYer, including cleaning the drain filter, inspecting the drain hose for blockages, and reseating wiring harness connectors. However, diagnosing and replacing the Inverter PBA involves working with internal electronics and requires disassembling the dishwasher, so most homeowners should have a qualified technician handle that portion of the repair.

Repair costs depend on the root cause. If only cleaning the drain filter or reseating connectors resolves the issue, there may be little to no parts cost. Replacing the Inverter PBA typically involves parts costs in the range of $80 to $200 or more, plus labor charges if a technician is performing the work. A full drain pump replacement adds additional parts cost on top of that.
