LG Washer Dryer: vibration sensor issue
What is this symptom?
Experiencing a vibration sensor issue with your LG washer dryer? This can manifest as a 'vS' or 'u5' error code, indicating abnormal vibration levels during spin cycles. The machine may stop operating entirely, disrupting your laundry routine. Understanding the common causes can help you troubleshoot effectively.
Important Tips for LG Models
- LG displays specific codes like VS or U5 for vibration sensor malfunction; official guides recommend initial troubleshooting (leveling, redistributing load) before service.
Possible Causes
Unbalanced load or overloading
How to Identify: Error displayed during or at start of spin; clothes bunched on one side of drum
Part: Drum/load distribution
Machine not level or improperly installed
How to Identify: Washer rocks when pushed corner-to-corner; error persists after redistributing load
Part: Leveling feet/floor contact
Faulty or defective vibration sensor or wiring
How to Identify: Error persists after leveling and redistribution; no obvious load imbalance; sensor circuit issues
Part: Vibration sensor assembly and wiring
Worn suspension components causing excessive vibration
How to Identify: Excessive vibration even with small, balanced loads; possible noise
Part: Shock absorbers/springs/suspension rods
DIY Solutions
Redistribute laundry and reduce load size
- Pause the cycle when safe to do so
- Open door and rearrange clothes evenly around drum
- Remove excess items if overloaded and restart cycle
Level the appliance on the floor
- Use a bubble level on top of machine to check level front-to-back and side-to-side
- Adjust leveling feet up or down until unit is stable with no rocking
- Tighten lock nuts on feet if present
Power reset to clear temporary sensor faults
- Turn machine off and unplug from power
- Wait 60 seconds
- Plug back in and restart a wash/dry cycle
