Safety first: prevent water damage

• If you hear water continuously filling, the ice maker area is overflowing, or water is leaking, shut off the refrigerator’s water supply valve immediately.
• Unplug the refrigerator (or turn it off at the breaker) if water is near electrical components or outlets.
• Dry up standing water to protect floors and prevent slipping.

Common causes of LG FE

An FE overfill/fill error is commonly caused by one of these:

• Water inlet valve stuck open (mechanical failure or debris preventing it from closing)
• Control signal/relay issue keeping the valve energized too long
• Fill/level sensing problem (pressure switch/level sensor or related circuit not reporting correctly)
• Kinked or misrouted water line causing abnormal flow behavior (less common, but worth checking)
• Ice maker fill tube issue (misaligned tube, ice blockage, or splash causing overflow symptoms)

What you can safely check at home

1) If it’s actively filling or leaking, turn the water off first

Locate the shutoff valve feeding the refrigerator (often under the kitchen sink, behind the fridge, or in a nearby utility space). Turn it clockwise to close.

If water stops immediately after shutting the valve: that strongly suggests the issue is in the refrigerator’s fill system (valve, control, or sensing), not your household plumbing.

2) Drain and dry any excess water

• Remove the ice bin and check for standing water or unusually wet/solid ice clumps.
• Dry visible water around the ice maker area and the bottom of the freezer (if applicable).
• Check for a frozen/overflowed fill tube area (icicles or ice buildup can redirect water).

3) Do a power reset (after water is off and things are dry)

1. Unplug the refrigerator (or switch it off at the breaker).
2. Wait 5 minutes.
3. Restore power.

If FE was triggered by a temporary control glitch, this may clear it. If it returns, keep the water supply turned off until the root cause is addressed.

4) Check the water line and fittings for obvious issues

• Look for kinks in the supply line behind the refrigerator.
• Check fittings for drips (valve connection, line couplers).
• If you see a slow drip, leave the water off and schedule service.

5) If your unit has an ice maker: watch the first fill after restoring water

Once everything is dry and you’ve reset power, you can briefly turn water back on and observe:

• If water continues filling or you hear constant flow, turn the water off again right away.
• If it fills normally once and stops, FE may have been a one-time event (still keep an eye on it).

Tip: If you need the refrigerator running but want to avoid a mess, you can keep the water supply off temporarily. Cooling will still work; you just won’t have ice or water dispensing.

When to call our friendly technicians in yellow

Schedule service if:

• FE returns after a reset
• The refrigerator keeps trying to fill or you hear ongoing water flow
• You have repeated leaking/overflowing in the ice maker area
• The water supply must remain off to prevent flooding

Most repairs involve testing whether the water inlet valve is sticking open, verifying the fill/level sensing circuit, checking wiring, and confirming whether the control board/relay is operating the valve correctly.

What not to do

• Don’t leave the water on if the unit is actively overfilling or leaking.
• Don’t ignore dripping inside the freezer — it can freeze into ice buildup and create a bigger mess.
• Don’t bypass safety steps around water near electrical components.
