LG dishwasher error codes
Extra LG dishwasher codes beyond the common OE/IE set: these cover heating, sensor and drain faults. Find your code below for meaning and safe checks.
| Code | Meaning | Severity | First action |
|---|---|---|---|
| FE | Water fill fault (overfill) | Often fixable at home | The machine detected water above the expected level — inlet valve stuck or pressure switch faulty. |
| HE | Heater fault | Engineer usually needed | The dishwasher could not heat water to temperature — heater or thermistor fault. |
| AE | Leak / waterproof system | Often fixable at home | Water was detected in the base pan, so the machine has shut down for safety. |
Safety first
Unplug before any check. Never open panels beyond the filter flap. Anything involving internal wiring, the heater or gas must go to a professional — see each code page for its "call a professional when" line.
