LG Washer Dryer: water flooding during dry cycle
What is this symptom?
Experiencing water flooding during the dry cycle of your LG washer dryer combo? This issue may lead to soaking wet clothes and potential internal flooding. Typically, excess water could indicate a stuck inlet valve, a malfunctioning control board, or a clogged drain. Understanding these causes can help you address the problem effectively.
Important Tips for LG Models
- LG washer-dryer combos use a condensing system during drying that uses small amounts of water; some moisture or small water pools can be normal.
Possible Causes
Stuck or defective water inlet valve
How to Identify: Water continues flowing into drum during dry cycle or after wash completion; turning off water supply stops flooding; water still enters even when unit is off.
Part: Water inlet valve assembly (solenoid valve)
Control board energizing inlet valve at wrong times
How to Identify: Voltage present at the inlet valve solenoid when it should be off; unpredictable water filling behavior across cycles.
Part: Main control board
Poor drain clearance or clogged drain filter
How to Identify: Residual water remains because the drain pump cannot fully clear water; water backs up during dry cycle steam condensation.
Part: Drain pump filter / drain path
DIY Solutions
Inspect/clean drain pump filter and drain hose
- Turn off and unplug the washer-dryer combo.
- Open the lower front access cover.
- Place a bucket/towels to catch residual water.
- Remove and clean the drain pump filter of debris.
- Straighten and inspect the drain hose; remove kinks or clogs.
- Reassemble and run a short cycle to test.
