What the Overflow error error code actually means

Your LG washer detected that water filled up too high inside the drum three separate times, so it stopped the cycle to protect your home from flooding. This usually means the washer is having trouble controlling how much water enters or drains from the machine. A simple restart may clear the error if it was a temporary glitch, but repeated occurrences point to a part that needs inspection or replacement.

Questions people ask about Overflow error

What does Overflow error mean on a LG washer?
The overflow error means the washer detected that water inside the drum rose to an unsafe level three consecutive times. The machine stops operation automatically to prevent water damage. This error involves the water level control system, including the inlet valve, pressure sensor, and associated hoses.
How do I fix the overflow error on my LG washer?
Start by powering the machine off and restarting it to see if the error clears. Then inspect the pressure hose for kinks or blockages, verify you are using HE detergent in the correct amount, and check the drain filter for clogs. If the error persists, the water inlet valve or pressure sensor likely needs to be tested and replaced.
How much does it cost to repair an LG washer overflow error?
Repair costs vary depending on the cause. Clearing a clogged drain filter or pressure hose is essentially free if you do it yourself. Replacing a water inlet valve or pressure sensor typically costs between $20 and $80 for the part alone, with professional labor adding $100 to $200 or more depending on your location and the technician's rates.
Will resetting my LG washer clear the overflow error?
Turning off the power and restarting the washer is the recommended first step and may clear the error if it was caused by a temporary glitch. However, if the underlying cause such as a faulty inlet valve or pressure sensor is still present, the error will return after the overflow condition occurs three more times. A reset alone is not a fix for a hardware fault.
Is it safe to keep using my LG washer when the overflow error appears?
You should not continue running the washer while the overflow error is active. The error exists specifically to stop the machine before water overflows onto the floor. Running the washer with a faulty inlet valve or pressure sensor risks water damage to your home and could potentially damage the machine's motor or electronic components.
