Why is detergent not dispensing in my LG WT8400CB?

  Lisa GoodmanSep 2, 2025
  If your LG Washer is not dispensing detergent completely or at all, make sure that detergent and additives are put into the correct dispenser compartments. Ensure that you're using the suggested amount of detergent. Verify that both hot and cold water faucets are fully on. Press the Power button to turn on the washer if the control panel has powered off due to inactivity. Ensure the power cord is plugged in, the water supply is on, the cycle is set correctly, the lid is closed, and the circuit breaker/fuse is not tripped/blown.

  If your LG Washer is not filling properly, ensure that the inlet filters on the fill valves are not clogged. Check that inlet hoses are not kinked or clogged. Make sure that both hot and cold water faucets are turned on all the way. Close the lid completely, ensuring nothing is caught underneath. Note that the water will not normally cover the clothes.

  If your LG Washer will not turn on, first ensure that the power cord is properly plugged into a grounded outlet. Check if the house fuse is blown or the circuit breaker has tripped; reset the breaker or replace the fuse. Do not increase fuse capacity, and if there's a circuit overload, have it corrected by an electrician.

  If your LG Washer is leaking, check the hoses and connectors for leaks, cracks, and splits, and tighten the hose connections. Make sure that house drain pipes are not clogged. Ensure the drain hose is properly inserted into the drain connector and secured. If washing large items, use the Bedding cycle and avoid washing more than half a load of items that float. Reduce the amount of detergent used, especially if the load is small or the water is soft.

  Michael TurnerAug 22, 2025
  If your LG Washer shows an IE INLET ERROR, it indicates a water inlet issue. First, ensure that the water supply faucets are fully open. Check that the water inlet hoses are not kinked, pinched, or crushed. Also, the water inlet filters may be clogged, consider cleaning the inlet filters. Verify that household water pressure is adequate by checking another faucet. Avoid using leak-limiting hoses.
