What the 3 error code actually means

Your LG washer is showing error code 3 because it tried to drain the water out of the tub but the water did not drain fast enough or at all. This is usually caused by a clogged filter, a kinked drain hose, or a blocked pump. Until the drainage problem is fixed, the washer will not complete its cycle.

Questions people ask about 3

What does 3 mean on a LG washer?
Error code 3 on an LG washer is a drain error indicating that the machine could not remove water from the tub within the allotted time. The washer monitors the drain cycle and shuts down with this code when drainage does not complete on schedule. Common triggers include a clogged pump filter, a blocked impeller, or a kinked drain hose. The machine will not resume normal operation until the drainage issue is resolved.
Is it safe to keep using my LG washer when error code 3 appears?
You should not continue running the washer while error code 3 is active. The machine is halting the cycle because water is not draining, and forcing additional cycles can strain the pump motor and risk water remaining in the drum for an extended period. Leave laundry in the machine temporarily, resolve the drain issue, and then restart the cycle. Ignoring the error repeatedly can lead to pump motor failure or water damage.
How much does it cost to repair an LG washer with error code 3?
If the fix is simply cleaning a clogged pump filter or straightening a kinked hose, the repair costs nothing beyond your time. If the drain pump motor has failed and needs replacement, parts typically range from around 30 to 100 dollars depending on the model, with professional labor adding another 75 to 150 dollars in most areas. A faulty water level pressure sensor is generally less expensive, with parts in the 20 to 60 dollar range. Getting a diagnosis from a qualified technician before purchasing parts is recommended if basic cleaning does not resolve the error.
How do I fix error code 3 on my LG washer?
Start by checking the drain hose for kinks, twists, or freezing and straighten or thaw it as needed. Next, locate the pump access panel at the front lower section of the washer, drain residual water using the small drain tube, then remove and clean the pump filter thoroughly. Also inspect the impeller inside the pump housing for debris such as socks, coins, or lint buildup. If these steps do not resolve the issue, the drain pump motor or water level sensor may need to be replaced.
Will resetting my LG washer clear error code 3?
Performing a reset by unplugging the washer for a few minutes may clear the code temporarily and allow a cycle to start, but the error will return if the underlying drain restriction has not been fixed. A reset does not repair a clogged filter, blocked impeller, or kinked hose. Treat the reset as a diagnostic step, not a solution. Always inspect and address the physical cause before running another full cycle.
