FE

Fan Error

Severity

Low

When a LG Dishwasher shows FE on its display, the internal diagnostic system has flagged a condition known as "Fan Error". Most repairs for this code are straightforward and can be completed at home.

Owner's Summary

Your LG dishwasher's drying fan has stopped working. The machine still washes normally — it just won't blow hot air to help dry the dishes at the end of the cycle. This is a convenience issue, not an urgent repair.

Symptoms

LG dishwasher not drying dishes, FE displayed at end of cycle

Common Causes

Failed drying fan motor
Fan blade jammed by debris
Wiring fault to fan motor
PCB fan control circuit failure

How to Fix

1 Inspect fan housing for debris or blockage
2 Test fan motor continuity and spinning resistance
3 Check wiring harness connector to fan motor
4 Replace fan motor if it fails electrical test

Tools You'll Need

Multimeter Electrical Contact Cleaner Flashlight

These are simple, low-risk fixes most homeowners can do with tools already in a basic toolbox.

Technical Explanation

LG uses a condensation drying system with a small fan to circulate air. The PCB monitors fan motor current to confirm operation. FE is posted when the fan does not reach the expected RPM during the dry phase — indicating motor failure or physical blockage.

Is It Safe to Keep Using?

No immediate risk to the appliance or to food safety. Fix within a few weeks.

Technician's Pro Tip

Toothpicks and small food debris are the most common cause of FE on LG dishwashers — they get sucked into the fan housing and jam the impeller. Remove the fan cover and inspect the impeller before ordering a new fan motor.
