What to do if LG WM4100H A shows IE INLET ERROR?
- D
  Dawn WernerAug 16, 2025
  If your LG washer displays an IE INLET ERROR, it could be due to several reasons. First, ensure that the water supply faucets are fully open. Check the water inlet hoses to make sure they are not kinked, pinched, or crushed. Also, the water inlet filters might be clogged, so you should clean them. Verify that your household water pressure is adequate by checking another faucet. If you are using leak-limiting hoses, consider that they may be falsely tripping and preventing the washer from filling.

What to do if my LG Washer won't turn on?

  Nicholas MoralesAug 19, 2025
  If your LG washer isn't turning on, start by ensuring the power cord is securely plugged into a grounded, 3-prong, 120-VAC, 60 Hz outlet. Also, check if a house fuse is blown, the circuit breaker has tripped, or a power outage has occurred. Reset the circuit breaker or replace the fuse, but do not increase the fuse capacity. If a circuit overload is the issue, have it corrected by a qualified electrician.

Why is my LG WM4100H A not filling properly?
- M
  Madison RochaAug 22, 2025
  If your LG washer isn't filling properly, several factors could be at play. Start by checking if the inlet filters on the fill valves are clogged. Also, inspect the inlet hoses for any kinks or clogs. Ensure that both hot and cold water faucets are fully turned on. Confirm that the washer door is completely closed, with nothing obstructing its closure. Keep in mind that this is a High-Efficiency (HE) washer, and the water level may not cover the clothes entirely, as the fill level is optimized for wash performance.

Why is detergent not dispensing properly in my LG WM4100H A Washer?
- M
  Marilyn JohnsonAug 26, 2025
  If detergent isn't dispensing properly in your LG washer, it could be due to a few reasons. Make sure that detergent and additives are put into the correct dispenser compartments and that the dispenser drawer is fully closed before starting the cycle. Using too much detergent can also cause issues; use the manufacturer's recommended amount and consider diluting it with water to the maximum fill line. Ensure that both hot and cold water faucets are fully turned on. A small amount of detergent residue is normal, but if it builds up, refer to the cleaning instructions.

Why does my LG WM4100H A make loud banging noises while filling with water?
- K
  Karen RodriguezAug 28, 2025
  Loud banging noises in your LG washer while filling with water can be attributed to a couple of plumbing issues. It may be a problem with your home's plumbing. For best results, install water hammer arrestors between the fill hose and the washer. Alternatively, your household water supply pressure might be very high. In this case, adjust the household water supply regulator to a lower pressure or contact a plumber.

What to do if LG WM4100H A shows OE WATER OUTLET ERROR?
- M
  Mrs. Kelly MooneyAug 31, 2025
  If your LG washer shows an OE WATER OUTLET ERROR, it means there's likely an issue with the drain hose. Ensure the drain hose is free of clogs or kinks and is not pinched behind or under the washer. Also, check that the end of the drain hose is not more than 96 inches (2.4 m) above the bottom of the washer; if it is, move it to a lower position.

What to do if my LG WM4100H A Washer shows svd OVERSUDSING DETECTION?
- M
  Michael JenkinsSep 12, 2025
  If your LG washer displays svd OVERSUDSING DETECTION, it means there is oversudsing of detergent. Do not add more detergent than the manufacturer’s recommended amount. To remove suds, turn the washer off then back on, then run the Rinse+Spin cycle. If too many suds are detected during spinning, the washer stops to help prevent leaking.
