LG Washer Error Code NO DRAIN

The NO DRAIN error means the washer was unable to fully drain the water from the drum within a 12-minute period. The control board monitors the drainage cycle and stops the machine if the water level sensor does not confirm an empty tub in time. This is a protective measure to prevent the washer from advancing through a cycle with standing water still inside. The most likely causes are a mispositioned drain hose, a clogged filter, or a faulty drain pump.

You should not continue running the washer while this error is active. The machine stops the cycle specifically to prevent operating with standing water in the drum, which could lead to mold, additional mechanical stress on components, or water leaking if a door seal issue is also present. Address the drainage problem before running another cycle.

If the fix involves only cleaning the pump filter or repositioning the drain hose, there is no parts cost and the repair can be done at home. If the drain pump needs replacement, parts typically range from roughly 30 to 100 dollars depending on the model, with professional labor adding another 80 to 150 dollars or more. A faulty pressure sensor is generally in a similar price range for parts. Total repair costs can range from nothing for a simple fix to 150 to 250 dollars or more for professional pump replacement.

Start by checking the drain hose position and confirming it is secured at a height between 0.9 and 1.2 meters above the floor. Next, clean the drain pump filter located behind the lower front access panel, as trapped debris is one of the most common causes. Inspect the drain hose for kinks or crushing and straighten it if needed. If those steps do not resolve the error, the drain pump or water level sensor may need to be tested and replaced.

A reset may temporarily clear the error code from the display, but it will not resolve the underlying drainage problem. If the root cause is not corrected, the error will return the next time the washer attempts to drain. Power cycling the machine by unplugging it for a few minutes can be useful to confirm whether a one-time glitch occurred, but persistent NO DRAIN errors require actual diagnosis and repair of the drainage system.
