What to do if my LG WM3400CW Washer shows an IE INLET ERROR?

  Tonya SullivanJul 28, 2025
  If your LG Washer displays an IE INLET ERROR, ensure the water supply faucets are fully open. Also, check that the water inlet hoses are not kinked, pinched, or crushed behind or under the washer. Be cautious when moving the washer during cleaning or maintenance. Clean the inlet filters as described in the MAINTENANCE section. Verify that your household water pressure is adequate by checking another faucet. If the flow is low, consider contacting a plumber to repair the water supply lines. Disconnect the water inlet hoses from the washer and run a few gallons of water through the hoses to flush out any dirt. Finally, avoid using leak-limiting hoses, as they can falsely trip and prevent the washer from filling.

Why does my LG WM3400CW beep and then do nothing when I press a button?
- M
  Mr. Ronald GonzalezAug 8, 2025
  If your LG washer beeps but doesn't start when you press a button, the Control Lock feature may be activated. To deactivate it, power on the washer, then press and hold the button labeled 'Control Lock' (or the button directly above or below where 'Control Lock' is indicated) for approximately 3 seconds. This should disable the lock and allow you to operate the washer normally.

How to stop loud banging noises from my LG WM3400CW when filling with water?
- N
  Natalie LunaAug 17, 2025
  The loud banging noises your LG washer makes while filling with water are likely due to a plumbing issue known as 'water hammer.' This can be resolved by installing a water hammer arrestor, which can be purchased at most hardware or home improvement stores.
