What UB1 means
UB1 appears on the Samsung WD90F27 series and WD90F53AVS Laundry Combo when the control detects waterproof items in the laundry. Such items can hold water and throw the drum out of balance. The unit asks you to remove them. You will see UB1 on the display, usually just before the spin starts, and the cycle will not spin properly until the load changes.
Common causes of UB1
- Waterproof jacket, mat or cover in the load
- Items that trap water inside
- Load imbalance caused by those items
1. Pause the cycle and open the door. 2. Take out any waterproof items, such as mats, pads or covers. 3. Spread the remaining laundry evenly around the drum. 4. Close the door and tap Start. 5. Wash the waterproof items separately if the label allows.
- If UB1 shows with no waterproof items, we cannot tell whether the balance sensor is reading wrongly.
- We check the drum movement and the sensing circuit before recommending a part.
- We quote in writing before any repair, and our workmanship is covered by a 30-day warranty.
Other Washer-Dryer Combo codes
What counts as a waterproof item?
Rain gear, bath mats with rubber backing and pet pads are common. They trap water and cannot spin evenly. Check pockets and linings as well, because a coated liner can count even when the outer fabric is not waterproof.
Can I put them back with other laundry?
Not in the same cycle. Wash them separately with a small balanced load if the care label allows. Before washing them, read the care labels, since some coated items must never go in a machine.
UB1 appears without such items. What now?
Check the load balance and leveling. If it persists, we inspect the sensing circuit and drum movement. A bunched blanket or a single heavy item can cause the same reading, so rule those out as well.
Still unsure about UB1?
A technician diagnoses it on site and gives you the price in writing before any work starts.
