Samsung Washing Machine ND Error Code
Water not draining from the drum
What this error means
ND is Samsung's No Drain error—the drain pump ran but the water level sensor still read high after the allotted drain window. The washer stops before high-speed spin to avoid running with a full tub.
How ND is detected
When ND 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 ND calls are resolved without parts: open the small access panel at the front bottom, drain into a pan, twist out the filter. 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 ND 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
- Pump filter clogged with lint, coins, or hair at the front access panel
- Drain hose kinked behind the washer or pushed too deep into the standpipe
- Excess suds from non-HE detergent trapping water in the pump
- Failed drain pump motor humming without moving water
Step-by-step fixes
- 1Open the lower front access panel, drain the emergency hose into a pan, and clean the pump filter
- 2Straighten the drain hose and keep clearance from the wall so it cannot kink
- 3Disconnect at the standpipe and confirm water flows freely during Spin Only
- 4Run Rinse & Spin with no detergent if suds were visible before ND appeared
When to call a technician
Pump hums during drain but water never moves—the impeller or drain pump motor needs replacement.
Affected models
- Samsung WF45T6000AW
- Samsung WF45R6100AW
- Samsung WA50R5400AW
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use washing machines to prevent ND from lint and food debris buildup.
- Record when ND 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 ND; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting ND; reversed plugs on pumps and valves cause immediate repeat faults.
