Samsung Dishwasher Error Code 5C6

The 5C6 code indicates a BLDC wash pump error. The dishwasher attempted to restart the pump multiple times and could not get it running normally. Sub-codes C1, C4, and C8 identify whether the specific issue is overcurrent above 2A, a phase loss in the wiring, or a mechanically locked pump impeller. The dishwasher will not complete a cycle until the underlying fault is resolved.

No, you should not continue running the dishwasher while the 5C6 error is active. The wash pump is not functioning correctly, which means water is not being circulated properly and the machine will not clean dishes effectively. Repeated failed restart attempts can also put additional stress on the control boards, potentially worsening the fault.

Repair costs vary depending on the root cause. Clearing a foreign object from the pump is typically a low-cost service call in the range of $75 to $150 for labor. Replacing the wash pump motor generally costs between $150 and $300 including parts and labor. Replacing the Inverter PBA or Main PBA can push total repair costs into the $200 to $450 range depending on parts pricing and local labor rates.

Some causes of the 5C6 error are DIY-friendly. Clearing a foreign object from the pump impeller or reseating a loose wire connector does not require special tools or parts. However, replacing the wash pump motor, Inverter PBA, or Main PBA involves working with electrical components and disassembling the dishwasher, which is better suited to a technician if you are not comfortable with appliance repair.

A reset may temporarily clear the error display, but the code will return as soon as the dishwasher attempts to run the wash pump again if the underlying problem has not been fixed. The dishwasher already performed multiple automatic restart attempts before logging the fault. A reset is useful for confirming whether a one-time glitch occurred, but it is not a solution for a mechanical or electrical pump failure.
