What Does LG Dishwasher Error Code FE Mean?
LG dishwasher error code FE stands for Fill Error. It appears when the dishwasher detects that the water level is higher than normal during the fill stage.
In simple terms, FE = dishwasher is overfilling with water.
Common Causes of LG Dishwasher FE Error
Faulty Water Inlet Valve
If the inlet valve is stuck open, water continues to flow even when the dishwasher tells it to stop.
High Water Pressure
Excessively high household water pressure can force too much water into the dishwasher.
Control Board Malfunction
A defective control board may fail to signal the inlet valve to close.
Float or Water Level Sensor Issue
If the float switch or sensor is stuck or damaged, the dishwasher cannot correctly detect water level.
Debris in the Inlet Valve
Sediment or mineral buildup can prevent the valve from closing fully.
How to Fix LG Dishwasher Error Code FE
Step 1: Turn Off Power and Water
Switch off the circuit breaker and close the dishwasher’s water supply valve.
Step 2: Check for Visible Overfilling
Open the dishwasher and inspect for unusually high water levels or water spilling into the base.
Step 3: Inspect the Water Inlet Valve
Look for leaks, mineral buildup, or signs the valve is stuck. If water flows even when power is off, the valve needs replacement.
Step 4: Check the Float Switch
Ensure the float moves freely and is not blocked by debris.
Step 5: Reset the Dishwasher
Restore power after 10–15 minutes and run a short test cycle.
If FE returns, part replacement is likely required.
Can You Fix FE Without Replacing Parts?
Sometimes, yes. If FE is caused by:
Temporary pressure surge
Minor debris blocking the inlet valve
Sensor stuck due to residue
A reset and cleaning may solve it. However, repeated FE errors usually mean the inlet valve must be replaced.
When to Call a Technician
You should contact a professional if:
The dishwasher keeps filling even when turned off
FE error appears repeatedly
Water leaks from the base
You are not comfortable handling electrical components
Overfilling issues should not be ignored.
How to Prevent LG Dishwasher Error Code FE
Ensure proper household water pressure
Use a water softener if you have hard water
Clean dishwasher filters regularly
Avoid interrupting wash cycles
Inspect inlet hoses annually
LG dishwasher error code FE is an overfill warning designed to prevent water damage. While a reset or cleaning may help temporarily, persistent FE errors usually point to a faulty inlet valve or water level sensor. Addressing the issue early helps protect your dishwasher and your home from leaks.
