Samsung Washing Machine dE Error Code
Door not locked before cycle start
What this error means
dE (dE1, dE2, dL variants) stops fill and spin because the door lock switch never reported locked. Samsung front-loaders require confirmed latch before the inlet valves open—Child Lock with water in the tub can also trigger dE.
How DE is detected
When DE appears on a Samsung washing machine, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung WF45R6100AW, Samsung WF45T6000AW, 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: remove fabric from the gasket and press the door until a single lock click. 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
- Clothing caught in the door gasket fold
- Broken door hook or misaligned strike plate
- Failed door lock motor—buzz with no click at start
- Child Lock enabled with water in tub and door opened
Step-by-step fixes
- 1Remove fabric from the gasket and press the door until a single lock click
- 2Disable Child Lock from the panel if enabled with water present
- 3Power-cycle two minutes, then close the door firmly and restart
- 4Listen at the lock during start—continuous buzz suggests a failed actuator
When to call a technician
Door physically latched with dE every cycle requires door lock assembly replacement.
Affected models
- Samsung WF45R6100AW
- Samsung WF45T6000AW
- Samsung WW22K6800AW
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use washing machines 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 washing machine—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.
