Why won't my LG WM3431HW Washer start?

  Tricia StevensJul 26, 2025
  If your LG Washer won't start, ensure the plug is securely fitted in the wall outlet. Check the circuit breaker or replace the fuse, without increasing its capacity. If there's a circuit overload, have it fixed by a qualified electrician. Also, make sure the water supply tap is on, the door is closed, and you've pressed the Start/Pause button. Note that it may take a moment for the washer to start spinning after pressing Start/Pause, as the door must lock first.

  If your LG Washer is leaking water, check and tighten the hose connections. If needed, unclog the drain pipe, and contact a plumber if necessary. Other issues could be excessive suds, slow draining, or water not entering the washer properly. Reduce the amount of detergent you're using, and ensure you're using HE (High Efficiency) detergent. Check other taps in the house and fully open the tap. Straighten the hose and inspect the filter of the inlet hose. Clean and straighten the drain hose, also clean the drain filter.

  To address rattling, clanking, thumping, or vibrating noises from your LG Washer: stop the washer and inspect the drum and drain filter. If the noise continues after restarting, it may require service. If the sound persists, the washer might be unbalanced; stop it and rearrange the load. Also, ensure all four leveling feet are firmly on the floor during the spin cycle. Refer to the Installation Instructions for removing shipping bolts.

  If your LG Washer is experiencing drying problems: avoid overloading the washer. Ensure the washer is draining properly to remove enough water from the load. If the load is too small, add a few towels to help with tumbling.
