Samsung Oven E-0A Error Code
Cavity temperature exceeded 650 °F outside clean mode
What this error means
E-0A is an Overheating Error—the probe reported above 650 °F (343 °C) while the oven was on and not in self-clean. Samsung disables heat immediately. A shorted sensor telling the board the oven is cold while heat runs wild is a frequent cause.
How E-0A is detected
When E-0A appears on a Samsung oven, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung NE59M6850SS, Samsung NE63T8751SS, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most E-0A calls are resolved without parts: turn off the breaker immediately if e-0a appears with smell or smoke. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If E-0A returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Temperature sensor shorted reading falsely low to the board
- Relay welded closed on the bake or broil circuit
- Cooling fan not running during broil on convection models
- Failed board logic after power surge
Step-by-step fixes
- 1Turn OFF the breaker immediately if E-0A appears with smell or smoke
- 2Wait until the cavity is completely cool before opening or resetting
- 3Do not restart broil until the code clears and sensor wiring is inspected
- 4Retry standard Bake at 300 °F only after a full cooldown and breaker reset
When to call a technician
E-0A on moderate setpoints after cooldown requires sensor ohms test and relay board diagnosis—safety priority.
Affected models
- Samsung NE59M6850SS
- Samsung NE63T8751SS
- Samsung NV51K7770DS
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use ovens to prevent E-0A from lint and food debris buildup.
- Record when E-0A appears in the cycle and whether it clears after a 60-second power reset on your Samsung oven—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for E-0A; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E-0A; reversed plugs on pumps and valves cause immediate repeat faults.
