LG Washer Dryer: not functioning
What is this symptom?
If your LG washer dryer is not functioning, you may notice that it won't power on or respond to cycle selections. This issue can manifest as no lights, sounds, or drum movement, indicating a possible power supply issue or a fault in the door lock mechanism. Understanding the common causes can help you troubleshoot effectively.
Important Tips for LG Models
- LG washer dryer combos use a water-free drying system and require correct drain hose positioning for proper drying performance; unrelated to no power but relevant if symptom includes drying failure.
Possible Causes
Power supply issue (no power to unit)
How to Identify: No lights, display, or sounds; testing outlet with another appliance also shows no power.
Part: Power cord / outlet / breaker
Door/lid not closed or faulty door lock mechanism
How to Identify: Machine will not start if door isn’t securely closed; may show locked door error or not accept start command.
Part: Door lock assembly
Control board or electronic control failure
How to Identify: Unit remains unresponsive after checking power and door; resets fail; error codes may appear.
Part: Main control board
Internal fuse or thermal safety device blown
How to Identify: No power with proper supply and intact power cord; requires multimeter testing inside unit.
Part: Thermal fuse / internal fuses
DIY Solutions
Verify and restore power supply
- Ensure washer dryer is plugged directly into a wall outlet — avoid power strips.
- Check home circuit breaker for trip and reset if needed.
- Test the outlet by plugging in another device to confirm it provides power.
Ensure door is properly closed and latched
- Open and firmly close the washer dryer's door until you hear the latch engage.
- Attempt to start the cycle again.
Perform a hard reset
- Turn off the circuit breaker for the washer dryer and unplug the unit.
- Wait 5 minutes, then turn breaker back on and plug the unit in.
- Attempt to power on the machine.
