Samsung Dishwasher OE Error Code
Overfill—too much water in the tub
What this error means
OE reports the water level above the safe threshold—often inlet valve stuck open, failed float switch, or suds mimicking high level. Samsung stops fill and may run drain to protect the kitchen floor.
How OE is detected
When OE appears on a Samsung dishwasher, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung DW80B6060US, Samsung DW80N3030US, 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 OE calls are resolved without parts: turn off the supply valve under the sink immediately. 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 OE 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
- Inlet valve solenoid stuck open after power surge
- Float or pressure sensor hose disconnected
- Excess detergent creating foam that reads as high water
- Drain failure leaving water from prior cycle plus new fill
Step-by-step fixes
- 1Turn off the supply valve under the sink immediately
- 2Cancel and run drain-only to lower the level
- 3Inspect the float assembly in the tub bottom for free movement
- 4Retry with half the recommended detergent on the next cycle
When to call a technician
Tub fills with supply off—replace inlet valve before next use.
Affected models
- Samsung DW80B6060US
- Samsung DW80N3030US
- Samsung DW80R7031US
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dishwashers to prevent OE from lint and food debris buildup.
- Record when OE appears in the cycle and whether it clears after a 60-second power reset on your Samsung dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for OE; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting OE; reversed plugs on pumps and valves cause immediate repeat faults.
