Samsung Washing Machine Error Code Ub
The washer cannot balance the load well enough to spin safely, so it slows down or stops. This is normally about how the laundry is loaded, not a broken machine.
Also shown as: UE, E4, Ur
Common causes
- One heavy item washed alone, such as a bath mat or duvet
- Laundry tangled into a single ball
- Washer standing on an uneven or soft floor
- Load far too small or too large
What to check, in order
- Pause the cycle and spread the laundry evenly around the drum.
- Add a couple of towels when washing a single heavy item to balance the load.
- Check the machine sits level and does not rock; adjust the feet if it does.
- Restart with a spin cycle.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, taps opened. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the machine back in and restore the water supply.
- Run a short rinse and spin, or the shortest wash programme, and watch the stage where the code appeared before (filling, washing, draining or spinning).
- If the cycle finishes with no code, the fault is cleared. If the code returns at the same stage, write down the code and that stage before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code Ub, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Parts that may be involved
Suspension rods (top-load models)
Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
