Samsung Washer Error Code nd

The nd code means the washer detected a drain error and could not remove water from the tub within the expected time. It is triggered when the drain pump motor is blocked by foreign material, the drain hose is clogged or kinked, the pump motor has failed, the wiring terminal is disconnected, or in cold environments, water in the pump or hose has frozen. The pump motor should measure 14.2 ohms plus or minus 7% at 20 degrees Celsius to be considered functional.

No, you should not run the washer while the nd code is active. The machine has halted because it cannot drain, meaning water is still sitting in the tub. Running additional cycles without resolving the drain problem can cause the motor to overheat or allow water to overflow. Resolve the drain issue before attempting another wash cycle.

If the fix is simply clearing a foreign object from the pump or repositioning the drain hose, there is no parts cost and only your time is involved. A replacement drain pump assembly typically costs between 40 and 120 dollars in parts depending on the model. If you hire a technician, expect total repair costs in the range of 150 to 300 dollars including labor, diagnosis, and parts.

Many cases of the nd code can be resolved without professional help. Start by checking the drain pump filter for trapped objects and inspect the drain hose for kinks or clogs. If the pump impeller spins freely and the hose is clear, use a multimeter to check pump motor resistance at the terminals and compare it to the specification of 14.2 ohms at 20 degrees Celsius. If the motor is out of spec, the pump assembly will need to be replaced, which is a moderately involved repair requiring access to the pump housing.

A reset may temporarily clear the nd code display, but the error will return on the next cycle if the underlying cause has not been corrected. Resetting does not fix a blocked impeller, a failed pump motor, or a kinked drain hose. Use a reset only to clear the code after you have completed the necessary repairs and confirmed the pump is functioning properly.
