What to do if my LG LDF5545ST displays a DRAIN ERROR?

  Ian JohnsonJul 25, 2025
  If your LG Dishwasher displays a DRAIN ERROR, it indicates that the water level isn't reaching the normal level. Here's what you can check: * Ensure the filter assembly isn't blocked by cleaning it. * Check the drain hose for kinks or blockages and remove them. * Inspect the inner hole of the drain case; if blocked, repair or replace the drain motor. * Clean the air gap if it's clogged. * Remove the knock-out plug from the garbage disposal if it hasn't been already. * If the washing motor is locked or defective, replace the pump casing assembly. * Verify the wiring connection and reconnect if necessary. * Clean the drain motor if the impeller is stuck. * If the controller is faulty, consider replacing it.

  If your LG Dishwasher is showing an INLET ERROR, it means the dishwasher isn't reaching the normal water level. Here are some things to check: * Make sure the water supply tap is fully open. * Inspect the inlet hose for any kinks and repair if needed. * If the water pressure is too low (below 10 psi) or too high (above 120 psi), you may need to call a plumber. * Clean the filter of the inlet valve if it's clogged. * Check the electric resistance of the inlet valve (it should be 23~27?). * Check and reconnect the wiring if necessary. * Replace the air breaker if the impeller is stuck. * Check the electric resistance of the hall sensor. * Consider replacing the controller if it's faulty.
