LG Dishwasher FE Error Code: What It Means & What to Check
If your LG dishwasher is showing an FE error code, it usually means the machine believes there is too much water in the tub. In many cases, the unit will run the drain pump to protect itself. The most common homeowner-safe starting points are checking for oversudsing, confirming the dishwasher is level, and looking for obvious signs of leaking or unusual filling. LG’s own guidance also ties FE or FE/AE-type events to excess water supply, leak detection, door or leveling issues, and water getting where it should not. Official LG support.
Common Symptoms
- FE error code on the display
- Dishwasher seems to keep draining or runs the drain pump unexpectedly
- Too much water in the tub
- Water or suds visible inside the machine
- Cycle stops before finishing
- Possible leaking or signs of moisture around the dishwasher
Safety First
Because FE is related to overfilling or excess water, treat it as a higher-priority dishwasher code. If you see water on the floor, shut the dishwasher off and avoid continuing to run cycles until the cause is clearer. Watch for slip hazards and protect nearby flooring if water is escaping the unit.
Quick Checks You Can Try
- Turn the dishwasher off. If the unit is actively filling or draining strangely, stop the cycle.
- Reset power once. LG commonly recommends powering the unit off, switching the breaker off for about 10 seconds, and then restoring power.
- Check for oversudsing. If regular dish soap or too much detergent was used, extra suds can confuse water-level sensing and trigger this code.
- Look for obvious water buildup. Check the tub and the area around the dishwasher for signs of excess water or leaking.
- Confirm the dishwasher looks level. LG notes leveling and door alignment can contribute to FE or AE-style water errors.
- Do not keep forcing cycles. If FE comes right back, repeated use can make leaking or water damage worse.
What This Code Usually Means
On LG dishwashers, FE generally points to a fill error — in plain language, the dishwasher thinks there is too much water in the unit. LG says the machine may automatically run the drain pump when this happens. Depending on the model and what caused the event, the root issue may be oversudsing, excess incoming water, a leak-related condition, leveling or door alignment problems, or a component that is no longer reading water level correctly.
Model-to-model details can vary a little, so FE is best treated as an overfill or water-management warning rather than assuming one exact failed part from the start.
Most Common Causes
- Too much detergent or the wrong soap creating excess suds
- Too much water entering the dishwasher
- Dishwasher not level
- Door alignment issue allowing abnormal water behavior
- Leak condition or moisture where the dishwasher should not detect it
- Water-level sensing problem
- Fill valve issue allowing too much water in
- Water getting into the Heat Dry blower area
Likely Parts or Areas a Technician May Check
- Water inlet valve
- Water-level sensor or pressure-sensing system
- Drain pump operation during the fault
- Door alignment and seal area
- Base-pan or leak-detection area
- Hoses, sump area, and internal water path for leaks
- Leveling and installation setup
When to Call Beacon
If the FE code returns after a basic reset, if the dishwasher appears to be overfilling, or if you notice leaking, it is a good time to stop there and have it checked. This is not one of the better codes to ignore because water issues can become cabinet, flooring, or repeat-service problems.
Our friendly technicians in yellow can help track down whether the problem is detergent-related, installation-related, leak-related, or caused by a failing component.
Prevent This Next Time
- Use only dishwasher detergent made for automatic dishwashers
- Avoid overfilling the detergent dispenser
- Wipe up obvious leaking or spillover quickly
- Do not ignore repeated drain-pump behavior or unexplained standing water
- If the dishwasher was recently installed or moved, recheck leveling

Frequently Asked Questions
What does FE mean on an LG dishwasher?
FE usually means the dishwasher has detected a fill error, which commonly means too much water is in the unit.
Is LG dishwasher FE a leak code?
It can be related. LG links FE or FE/AE-type events to excess water, leak detection, and other water-management problems, so it is smart to look for signs of leaking.
Can too much soap cause an LG dishwasher FE code?
Yes. Oversudsing from the wrong soap or too much detergent is one of the common causes LG lists.
Should I keep running my dishwasher if it shows FE?
Usually no. Since FE is tied to too much water or water-related faults, repeated cycles can make the problem worse.
Will turning the breaker off reset an LG dishwasher FE code?
Sometimes. LG commonly recommends turning the unit off, switching the breaker off briefly, and then restoring power. If the code returns, more diagnosis is usually needed.
What part usually causes LG dishwasher FE?
There is not just one guaranteed part. Common possibilities include the inlet valve, water-level sensing system, leak-related components, or an installation and leveling issue.
