      If your LG Washer won’t start or spin, ensure the plug is securely in the wall outlet. Check the circuit breaker or replace the fuse, without increasing its capacity. Make sure the water supply tap is on. Close the door and press the Start/Pause button; allow a few moments for the washer to begin spinning, as the door must lock first.

      Brenda DonaldsonAug 18, 2025
      If you notice water leaks, excessive suds, or water entering the LG Washer slowly, check and tighten the hose connections and unclog the drain pipe. If needed, contact a plumber. To address excessive suds, reduce the amount of detergent or switch to HE (High Efficiency) detergent. Ensure another tap in the house is working, fully open the tap, straighten the hose, and inspect the inlet hose 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 persists after restarting, call for service. If the sound continues, the washer might be unbalanced; stop and redistribute the wash load. Ensure you've removed the shipping bolts as per the Installation Instructions. Adjust the leveling feet to ensure all four are firmly on the floor during the spin cycle.
