LG dishwasher Error Code FE
Fill error / overflow
Common Causes
- 1Inlet valve stuck
- 2Sensor failure
Dishwasher overflow can cause significant water damage to kitchen cabinets and flooring. Turn off the water supply valve immediately when FE appears.
Step-by-Step Troubleshooting
- 1
Turn off the water supply valve immediately to stop water entering the dishwasher
- 2
Check the base pan under the dishwasher for overflow water and mop up any standing water
- 3
The water inlet valve may be stuck in the open position — even with the dishwasher off, water will continue to enter if the valve is mechanically stuck
- 4
Inspect the float switch in the tub (small dome in the front-left corner of the tub floor) — it should move freely up and down
- 5
If the float switch is functional but FE persists, the main control board may not be receiving the float signal properly
Pro Diagnostic Tip
On LG QuadWash dishwashers, the float switch and the turbidity sensor work together to monitor water level. If the turbidity sensor fails and reads "clean" (low turbidity), the board may command additional fill cycles thinking it needs more water. Check both sensors.
