  An IE Inlet Error on your LG Washer indicates a water filling issue. Here's what to check: 1. Ensure the water supply faucets are fully open. 2. Inspect the water inlet hoses for kinks, pinches, or crushing, especially behind or under the washer. 3. Clean the water inlet filters, referring to the maintenance section for instructions. 4. Verify adequate water pressure by checking other faucets in your home. Disconnect the inlet hoses and flush them to remove any debris. If the flow remains low, contact a plumber. 5. Avoid using leak-limiting hoses, as they can falsely trigger and prevent filling.

Why does my LG WM3450CW beep and then do nothing when I press a button?

  If your LG Washer beeps when you press a button but doesn't start, 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 beneath where 'Control Lock' is printed) for approximately 3 seconds.

  Loud banging noises while your LG Washer is filling with water are usually related to your home's plumbing, not the washer itself. This phenomenon, known as water hammer, can be mitigated by installing a water hammer arrestor in your plumbing system.
