LG Washer Error Code 5C

The 5C code on an LG washer signals a drain error, meaning the washer cannot properly drain water from the drum. It is triggered when the drain pump impeller is restricted or not functioning correctly. Common causes include foreign objects inside the pump, a clogged drain hose, freezing in cold environments, a disconnected pump terminal, or a damaged pump motor. Identifying whether the issue is a physical blockage or an electrical fault will guide the correct repair.

It is not recommended to continue running the washer while the 5C code is active. When the drain system is not functioning, water remains trapped in the drum, which can lead to mold growth, component stress, and potential water damage if the machine attempts additional cycles. Address the drain issue before resuming use.

If the issue is a foreign object in the pump, the repair can often be completed at no parts cost, though a service call fee may apply if a technician is involved. A replacement drain pump assembly typically costs between $30 and $100 for the part, with professional labor adding $80 to $200 depending on location and the service provider. Diagnosing the cause accurately before ordering parts can help avoid unnecessary expenses.

Start by checking the drain pump filter and housing for foreign objects like coins, hairpins, or lint that may be jamming the impeller. Next, inspect the drain hose for kinks or blockages along its full length. If the washer is in a cold space, allow it to thaw before running a cycle. If those checks pass, inspect the wiring terminal at the pump for a loose connection, and if the pump still fails to operate, the pump assembly may need to be replaced.

A reset may temporarily clear the 5C code from the display, but it will return as soon as the washer attempts to drain again if the underlying problem has not been fixed. Unplugging the unit for a few minutes can reset the control board, but the drain pump obstruction, hose blockage, or electrical fault must be resolved for the error to stay cleared.
