LG Washer Dryer: not stopping water flow
What is this symptom?
Is your LG washer dryer continuously filling with water, even after the cycle has completed? This issue can lead to overflows and water damage. Common causes include a faulty water inlet valve, a malfunctioning pressure switch, or even control board issues. Addressing this promptly is crucial to prevent further complications.
Important Tips for LG Models
- Incorrect drain hose placement can cause water to flow back into the washer giving impression of continuous fill
- Official LG documentation notes water can remain in drum after cycle and water behavior may differ on washer/dryer combos
Possible Causes
Faulty water inlet valve stuck open
How to Identify: Water continues to fill even when cycle should have stopped or with power disconnected; water flows into drum without command
Part: Water inlet valve
Malfunctioning water level/pressure switch or pressure sensor
How to Identify: Washer doesn’t sense correct water level, overfills; pressure hose may be kinked, blocked, or cracked
Part: Water level pressure switch or air dome/pressure hose
Control board or electronic control malfunction
How to Identify: Other causes eliminated and washer still continues water fill; error codes may be present or intermittent electronics behavior
Part: Main control board (electronic control)
Drain hose installation or siphoning issue
How to Identify: Incorrect drain hose height can cause backflow or siphoning patterns misinterpreted as continuous fill; hose too deeply into drain
Part: Drain hose placement
DIY Solutions
Inspect and replace water inlet valve
- Turn off water supply and unplug washer dryer
- Access back panel and locate water inlet valve
- Test valve solenoids with multimeter for continuity; if stuck open, obtain correct replacement
- Remove wiring and hoses, install new inlet valve, reconnect everything and test cycle
Check and clear pressure hose or replace pressure switch
- Unplug appliance and remove appropriate panels to access pressure tube and switch
- Inspect pressure hose for kinks, clogs, cracks; gently clear or replace hose
