LG Washer Error Code Over Flooding Error

The Over Flooding Error means the washer detected water entering the drum beyond the acceptable level during its QC Mode diagnostic cycle. All process LEDs blink at once to signal the fault. The root cause is typically a malfunctioning inlet valve that is not closing properly when the control board commands it to stop water flow.

No, it is not safe to continue running the washer with this error present. An inlet valve that cannot close on command can allow water to overflow the drum, potentially causing water damage to the machine and surrounding area. The washer should remain out of service until the inlet valve has been inspected and repaired or replaced.

If the repair involves replacing the inlet valve, parts typically range from around $25 to $80 depending on the specific model, with professional labor adding $75 to $150 or more. If the control board is the source of the problem, repair costs will be higher, generally ranging from $150 to $350 or more for parts and labor combined.

A knowledgeable DIYer can inspect the inlet valve for visible debris, check the supply hose screens, and test the solenoid coil with a multimeter. If the valve is mechanically stuck or the coil has failed, replacing the inlet valve is a manageable repair for someone comfortable working with appliance water connections and basic electrical testing. Control board issues are more complex and may require a technician.

A reset may temporarily clear the error code, but it will not resolve the underlying problem. If the inlet valve is faulty, the over-flooding condition will recur and the error will return the next time the washer runs through its QC Mode or normal cycle. The valve must be diagnosed and repaired before the machine will operate reliably.
