Samsung Oven E-19 Error Code
Communication error between oven PCBs
What this error means
E-19 (E-83/C-F0 family) is a Communication Error between the main oven PCB and a sub-board—relay board, touch UI, or cooktop interface. Display may freeze or cancel cycles mid-preheat.
How E-19 is detected
When E-19 appears on a Samsung oven, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung NE58F9710WS, Samsung NE63A6511SS, 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-19 calls are resolved without parts: turn breaker off fifteen minutes per samsung hard-reset guidance. 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-19 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
- Loose ribbon cable after console removal
- Power surge during self-clean damaging UART lines
- Moisture on connectors after steam clean
- Failed sub PCB after overheating in the control bay
Step-by-step fixes
- 1Turn breaker OFF fifteen minutes per Samsung hard-reset guidance
- 2Avoid starting self-clean until E-19 clears on standard Bake
- 3Ensure the range cord is fully seated at the junction box—no extension cord
- 4Note whether E-19 appears only in self-clean or all modes for service
When to call a technician
Persistent E-19 after extended power loss requires ribbon inspection and model-matched PCB replacement.
Affected models
- Samsung NE58F9710WS
- Samsung NE63A6511SS
- Samsung NV51K7770DS
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use ovens to prevent E-19 from lint and food debris buildup.
- Record when E-19 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-19; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting E-19; reversed plugs on pumps and valves cause immediate repeat faults.
