Samsung Dishwasher Error Code 5C1

The 5C1 code means the dishwasher experienced a drain failure severe enough to exhaust its automatic retry logic. The drain pump attempted to evacuate standing water 11 times with 5-minute pauses between attempts, and when this cycle repeated 3 times without success, the control board stored the 5C1 fault and stopped operation. The most common causes are a blocked drain pump, a clogged drain hose, or a failed pump motor.

A reset may clear the code temporarily, but the error will return if the underlying drain obstruction or pump fault has not been resolved. Resetting the unit without addressing the cause means the dishwasher will again run through 11 failed drain attempts before locking out. Always identify and fix the source of the drainage problem before relying on a reset.

If the cause is simply a clogged hose or debris in the pump, the repair may cost nothing beyond your time. If the drain pump motor requires replacement, parts typically range from $40 to $120 depending on the model, with professional labor adding $80 to $200 on top of that. Getting the drain hose and filter cleared first is always worthwhile before committing to a parts replacement.

Start by removing and cleaning the filter assembly at the bottom of the tub, then inspect the drain pump housing for foreign material lodged against the impeller. Next, check the drain hose for kinks or blockages and confirm the connection point at the sink or disposal is clear. If the pump impeller is unobstructed but the error persists, the drain pump motor may need to be replaced.

You should not run the dishwasher while the 5C1 code is active. Standing water remaining in the tub from a failed drain cycle can develop bacteria and odors, and continuing to operate the appliance without resolving the drain fault risks water pooling under the unit or overflowing. Address the drainage issue before resuming normal use.
