What LG FE means

LG dishwasher error FE is a fill or overfill warning. The dishwasher has detected more water than expected and may automatically run the drain pump as a protective response. FE does not by itself prove that the water inlet valve has failed. Depending on the model and circumstances, excessive filling, heavy suds, a leak-related condition, installation alignment, water-level detection, or another fill-control problem may be involved.

Common causes

  • More water entering the dishwasher than the control system expects
  • Excessive suds caused by unsuitable detergent, including ordinary hand dishwashing liquid
  • A leak or abnormal water condition triggering the appliance protection system
  • The dishwasher not sitting correctly level or the door not aligning correctly on affected models
  • An internal fill-control or water-level fault that requires diagnosis if FE persists

Safe checks you can make

  1. Press the POWER button to stop the dishwasher and do not repeatedly restart the programme.
  2. Check the floor and the visible area around the dishwasher for water without moving or dismantling the appliance.
  3. If water continues entering after the dishwasher has been switched off, or a leak is visible, close the dishwasher water supply if the valve is safely accessible.
  4. Check whether ordinary washing-up liquid or another unsuitable detergent was used, and look for unusually heavy suds inside the tub if it is safe to open the door.
  5. If there is no visible leak or unsafe electrical condition, isolate the dishwasher electrical supply for at least 10 seconds, restore power, and attempt one restart as described by LG.
  6. If FE returns, stop using the dishwasher and record the full model number before arranging service.

Is it safe to keep using the appliance?

Do not continue running normal wash programmes while FE persists. If one power reset clears the code and there is no visible leak, uncontrolled filling, or excessive sudsing, monitor the appliance carefully. Stop using it and arrange service immediately if FE returns or water continues entering unexpectedly.
