LG Washer Error Code DRAIN Er

DRAIN Er means the washer could not complete its drain cycle within 12 minutes. The control board monitors drain progress and stops the cycle when that time limit is exceeded. It points to a problem in the drain system such as a clogged filter, a misrouted hose, or a faulty drain pump. Addressing the drain path is the first step toward resolving it.

You should not continue using the washer until the error is resolved. If the machine cannot drain properly, water may remain in the drum, which can lead to mold growth and unpleasant odors over time. Running additional cycles without fixing the drain issue will not clear the code and could put added strain on the pump motor.

If the fix is simply cleaning a clogged filter or repositioning the drain hose, there may be no parts cost at all, just your time. If the drain pump motor has failed and needs replacement, parts typically range from $25 to $80 depending on the model, with professional labor adding $75 to $150 or more. Diagnosing the specific cause first will help you determine whether this is a straightforward DIY fix or a job for a technician.

Start by checking that the drain hose is positioned correctly for your model type: routed downward on non-pump models or hung at the proper standpipe height on pump models. Next, clean the pump filter, which is usually accessible behind a small panel at the front lower section of the washer. If the hose and filter are both clear, inspect the hose for kinks and verify the standpipe is not blocked. If none of those steps resolve the issue, the drain pump motor may need to be tested and replaced.

A reset may temporarily clear the code from the display, but it will not fix the underlying drainage problem. The error will return as soon as the washer attempts to drain again and exceeds the 12-minute limit. The root cause, whether a clog, hose issue, or pump failure, must be corrected before the code will stay cleared.
