LG Washer Error Code nd

The nd code on an LG washer stands for a drain error, meaning the machine was unable to drain water within the expected time during a cycle. It can be caused by a blocked drain pump impeller, a clogged or kinked drain hose, a failed pump motor, a disconnected pump wiring terminal, incorrect supply voltage, or a frozen drain hose. You will typically notice water remaining in the drum when this code appears. Addressing the underlying cause is necessary before the washer will complete a cycle normally.

You should not continue running cycles while the nd error is active. The machine cannot drain properly, which means water will remain in the drum and the washer will not complete its cycle. Running the machine repeatedly in this condition can put additional stress on the pump motor. Address the cause of the drain error before resuming normal use.

Resetting the washer by unplugging it for a few minutes may temporarily clear the nd code from the display, but the error will return if the underlying cause has not been corrected. A reset does not fix a clogged pump, a failed motor, a blocked hose, or any other physical or electrical issue triggering the code. The drain system must be inspected and repaired to resolve the error permanently.

Start by checking the drain pump assembly for foreign material such as coins or debris that may be blocking the impeller, and remove anything found. Next, inspect the drain hose for kinks, clogs, or freezing and straighten or clear it as needed. Check that the wiring connector at the drain pump is fully seated. If the pump impeller spins freely and connections are secure but the error persists, measure the drain pump motor resistance to determine whether the pump motor has failed and needs replacement.

Repair costs vary depending on the cause. If the issue is simply a foreign object blocking the pump, you may be able to resolve it yourself at no parts cost. A replacement drain pump motor typically ranges from $30 to $80 for the part, with professional labor adding $75 to $150 depending on your area. If incorrect voltage caused broader component damage, total repair costs could be higher.
