LG Washing Machine: overflowing
What is this symptom?
Experiencing an overflow in your LG washing machine? This issue may result in water spilling from the drum, detergent drawer, or drainage area during operation or at cycle completion. Common culprits include clogged drainage systems, excessive detergent use, and potential faults in the water inlet valve or water-level sensor. Understanding these causes can help you address the problem effectively.
Important Tips for LG Models

Excess detergent causing foam overflow
How to Identify: Visible foam or suds spilling from detergent drawer or detergent area; excessive foam during wash cycle

Improper drainage system installation or reverse slope of household drain pipes
How to Identify: Overflow persists after unclogging machine drain; poor or slow drainage elsewhere in home plumbing
Part: Household drain installation
