Samsung Washing Machine 4E Error Code
No water entering the tub
What this error means
4E is Samsung's Not Filling error. The inlet valves energize but the water level sensor never sees a rise within the programmed fill window—often within two to four minutes depending on cycle. The machine aborts before agitation to avoid running dry.
How 4E is detected
When 4E 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 WF45T6000AW, Samsung WF45R6100AW, 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 4E calls are resolved without parts: turn both wall valves fully counterclockwise and confirm other fixtures have normal pressure. 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 4E 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
- Hot or cold supply valves closed or only partially open
- Kinked inlet hoses pinched against the wall
- Mesh strainers at the washer connections clogged with sediment
- Drain hose inserted too far into standpipe causing siphon during fill
Step-by-step fixes
- 1Turn both wall valves fully counterclockwise and confirm other fixtures have normal pressure
- 2Straighten hoses and keep 4–6 inches clearance from the rear panel
- 3Disconnect hoses at the washer, rinse the internal screens into a bucket, and reconnect
- 4Verify the drain hose standpipe insert is 6–8 inches deep—not deep enough to siphon fill water out
When to call a technician
Strong flow at the hose ends with a dry tub after fill usually means a failed dual inlet valve or pressure switch—not a plumbing issue.
Affected models
- Samsung WF45T6000AW
- Samsung WF45R6100AW
- Samsung WA50R5400AW
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use washing machines to prevent 4E from lint and food debris buildup.
- Record when 4E 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 4E; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting 4E; reversed plugs on pumps and valves cause immediate repeat faults.
