Samsung Washing Machine UR Error Code
Unbalanced load—redistribute and retry spin
What this error means
UR is Samsung's Unbalanced Reload code—the drum could not redistribute laundry enough to safely reach spin speed. The washer pauses and displays UR so you can open the door and rearrange items.
How UR is detected
When UR 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 WA52A5500AW, 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 UR calls are resolved without parts: open door and redistribute clothes 360° around drum. 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 UR 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
- Heavy items clumped on one side of the drum
- Single large piece such as a comforter without balancing towels
- Washer not level or transit bolts still installed on new delivery
- Worn shock absorbers allowing excessive tub sway
Step-by-step fixes
- 1Pause, open the door, and spread clothes around the full drum circumference
- 2Add similar-weight items when washing one heavy piece alone
- 3Level the washer with a bubble level on top and lock jam nuts on the feet
- 4Confirm four rear transit bolts with spacers were removed after install
When to call a technician
UR on every balanced full load after leveling suggests shock absorber or suspension spring replacement.
Affected models
- Samsung WF45T6000AW
- Samsung WA50R5400AW
- Samsung WF45R6100AW
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use washing machines to prevent UR from lint and food debris buildup.
- Record when UR 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 UR; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting UR; reversed plugs on pumps and valves cause immediate repeat faults.
