Samsung Dishwasher dE Error Code
Door not latched or switch open
What this error means
dE halts the cycle because the door switch never confirmed closed—Samsung will not fill or energize wash motor with an open door circuit. Child lock combinations can mimic dE on some models.
How DE is detected
When DE 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 DW80R9950US, 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 DE calls are resolved without parts: push the upper rack fully in and clear the gasket fold. 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 DE 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
- Upper rack rail stopping the door before latch engagement
- Utensil handle caught in the gasket
- Warped door latch hook or striker misalignment
- Failed door switch assembly
Step-by-step fixes
- 1Push the upper rack fully in and clear the gasket fold
- 2Close the door firmly until one audible latch click
- 3Inspect the striker plate on the tub frame for looseness
- 4Power-cycle and retry—listen for fill within 30 seconds of start
When to call a technician
Door closes flush with dE every start requires door latch switch replacement.
Affected models
- Samsung DW80B6060US
- Samsung DW80R9950US
- Samsung DW80N3030US
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dishwashers to prevent DE from lint and food debris buildup.
- Record when DE 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 DE; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting DE; reversed plugs on pumps and valves cause immediate repeat faults.
