Samsung dishwasher error codes
Extra Samsung dishwasher codes beyond the main 4E/1E set: these cover drain, sensor and electronics faults. Find your code below for the meaning and safe checks.
| Code | Meaning | Severity | First action |
|---|---|---|---|
| HE | Heater / water heat fault | Engineer usually needed | The dishwasher cannot heat the water to temperature within the allowed time — the heater, its wiring or the thermistor is at fault. |
| 5E | Drain fault (alternate display) | Often fixable at home | On some models the drain fault shows as 5E rather than 4E-style displays: water is not pumped out fully. |
| LE | Leak / water detected in base | Often fixable at home | Water has been detected in the base pan, so the electronics stop the machine and may run a drain-only cycle. |
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.
