Samsung Washer Error Code NC

The NC error code on a Samsung Laundry Combo washer means the filter has not been detected as correctly inserted. The machine's control system checks for proper filter placement before running, and if it does not sense a secure fit, it stops operation and displays NC. Reinserting the filter fully and firmly into its housing is the first step to clearing this code.

The NC error is a protective alert rather than a sign of a dangerous failure. The machine stops operation intentionally to prevent running without a properly seated filter, which could allow lint to accumulate in internal components over time and reduce drying efficiency. Addressing the error promptly by reinserting the filter correctly keeps the appliance operating safely.

If the filter simply needs to be reseated, there is no cost involved. If the filter itself is warped or damaged and needs replacement, a replacement filter typically costs in the range of $10 to $40 depending on the specific model. If the issue is traced to a faulty detection sensor or filter housing, a service call and parts could cost anywhere from $100 to $250 or more, depending on labor rates in your area.

Start by locating the filter on your unit and pulling it out completely. Check it for visible damage or warping, then reinsert it firmly, making sure it is aligned with the housing guides and seated flush. Once the filter is properly installed, press Start to resume the cycle, or turn the machine off, wait 2 to 3 minutes, and power it back on if the error does not clear immediately.

A reset alone will not permanently clear the NC error if the filter is still missing or incorrectly seated, because the machine will detect the same problem as soon as it runs its checks again. You need to properly reinstall the filter first. After the filter is correctly inserted, you can either press Start or cycle the power off and back on after 2 to 3 minutes to clear the code.
