Why is my LG Washer draining slowly or not at all?

  Karen LandryJul 25, 2025
  If your LG washer isn't draining properly, there are a few things you can check: * Ensure the drain hose is positioned no more than 3 feet below the elbow bracket. * Make sure the drain hose is lying on a smooth surface to prevent any kinks or bends. * If you suspect the drain hoses are frozen, try thawing them with warm water. * Inspect the drain pump plug cap and remove any accumulated dirt or debris.

What to do if the tub does not rotate in my LG WM4370HWA Washer?

  Barbara JohnsonAug 3, 2025
  If the tub in your LG washer isn't rotating, first, make sure the door is fully closed and securely latched. If the issue persists, rearrange the load to ensure it's balanced, then restart the washing machine. If the load is too large, the motor may overheat, preventing rotation. Allow the machine to cool down before restarting.

Inspect the inlet filter for clogs and clean it if necessary. 4. Verify that the water line is correctly connected to the cold water inlet. 5. Check the water lines to ensure they are not pinched, bent, or twisted by other objects.

What to do if item of clothing has gathered on one side of the tub in my LG WM4370HWA?

  Phillip AndersonAug 15, 2025
  If clothing items have gathered on one side of the tub in your LG washer, rearrange the items to help balance the load. Stuffed animals or mats can cause imbalance during spinning, potentially preventing proper draining. Ensure knitwear is balanced, and if washing blankets, load one at a time.
