Common questions about “LG dishwasher FE code”
What does FE mean on a LG dishwasher?+
It means the dishwasher detected too much water.
Can I clear FE by resetting the dishwasher?+
A restart may clear a stored display only after the underlying condition is corrected. Repeatedly resetting without correcting the cause is not a repair.
How do I clear it?+
Cancel the cycle, close the water tap if it may be a fill fault, drain the tub and restart. If FE returns, look at the inlet valve and water-level sensor.
Could suds cause FE?+
Excess detergent or hand soap can foam and trigger the level sensor. Run a rinse cycle after removing soap.
Is it safe to leave the dishwasher running with FE showing?+
No. FE means the machine thinks there is more water than there should be. Cancel the cycle, close the water supply if you can, and check the floor around the unit for leaks before running it again.
Can a level or installation problem cause FE?+
Yes. A dishwasher that is not level, or a drain hose that is looped too low, can leave water in the tub and make the level sensor read high. Check that the drain hose has a high loop and the unit sits level.
Which parts can cause a false FE?+
A faulty water-level sensor, a stuck inlet valve or a blocked filter can each make the machine believe the tub is too full. If FE returns after draining and restarting, those are the parts a technician will check first.
Does the FE code clear on its own?+
Sometimes after the tub drains and the machine is powered off and on. If it keeps returning, do not keep restarting cycles; note when it appears, since that timing helps a technician find the fault.
Can a dishwasher overfill and flood the kitchen?+
It can leak if the fill valve sticks open, which is why the dishwasher stops and shows FE. Turn off the water supply to the dishwasher until it has been checked.
How do I clear FE on an LG dishwasher?+
Turn off the power and the water for a few minutes, drain any standing water and restart. If FE returns, the inlet valve or the float needs a technician.
