Samsung Washer Error Code 15C

The 15C code on a Samsung washer signals a drain error on the upper washer unit. It means the drain pump motor is not moving water out of the drum as expected. Causes include a jammed or damaged pump impeller, a clogged drain hose, wrong voltage to the pump, or freezing conditions. Diagnosing the issue starts with checking the pump for foreign material and measuring the pump motor's resistance.

You should not continue running the washer with an active 15C error. If the machine cannot drain properly, water will remain in the drum, which can lead to mold growth, unbalanced loads, and potential overflow. Resolve the drain issue before running additional cycles.

A reset may temporarily clear the 15C code from the display, but if the underlying problem has not been fixed, the error will return as soon as the machine attempts to drain again. Resetting is useful for confirming whether the fault was a one-time event, but it is not a substitute for diagnosing and correcting the actual cause.

Some causes of the 15C error are DIY-friendly, such as clearing debris from the drain pump housing or straightening a kinked drain hose. More technical repairs, like measuring motor resistance or replacing a damaged pump motor, require a multimeter and basic comfort with appliance disassembly. If the pump motor itself is failed or voltage supply is irregular, professional service is recommended.

Repair costs vary depending on the root cause. Clearing a clogged drain hose or removing debris from the pump yourself costs little to nothing. If the drain pump motor needs replacement, parts alone typically range from $30 to $100 or more, and professional labor can add $75 to $200 depending on your location and service provider.
