While we strive to offer helpful advice for DIY appliance repairs, variations in models and configurations can lead to differences in troubleshooting steps, error codes and part replacements. For the most accurate guidance, we strongly recommend consulting the technical sheet for your specific appliance model.
What the error code means
The UB error code on a Samsung washer is an indicator of an unbalanced load, which simply means that the distribution of clothes inside the drum is uneven. This imbalance can prevent the drum from gaining enough momentum to loosen up tangled clothing.
An important safety feature integrated into Samsung washers triggers this error to protect both your appliance and laundry from potential damage due to unsafe spinning conditions.
Safety precautions
When working on any appliance, remember to keep safety first. Here are some tips to keep in mind:
- Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
- Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
- Take your time and don’t rush while working to prevent accidents and personal injuries.
- Work in a well-lit area so you can clearly see and access the interior parts.
- Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
- Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
- Check your user manual to see if there are specific installation or safety instructions for your part or appliance.
- Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
- Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury.
- If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it.
- Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
- When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
- Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water. Have towels ready for any residual water in the system when removing parts.
Troubleshooting steps
Rebalance the load
- Pause the washer and open the door or lid.
- Visually inspect the laundry items inside the drum.
- Untangle any tangled clothes or bunched-up fabrics in the drum.
- Redistribute your laundry evenly, ensuring that heavy items are not all on one side of the washer drum.
- Add or remove clothing items as necessary to create a more balanced load; this may involve adding more small garments or removing some large, heavy items from an overloaded drum.
- Close the door or lid and restart the washing cycle.
Check for obstructions
- Make sure there are no items caught between the washer drum and the outer tub.
- Check for any loose items or small pieces of clothing that may have fallen inside the washer during loading.
- Inspect the drain hose for any kinks or clogs that may be preventing proper water removal.
- Ensure that the washer is not placed on an uneven surface that impairs its stability and balance.
Check the suspension rods
To verify if the suspension rods are functioning correctly, follow these steps:
- Turn off the washer and unplug from the power supply.
- Check if there are any visible damage or wear and tear on the suspension rods.
- Push on each rod to check for any movement or looseness.
- The suspension rods should be firm and not wobbly; otherwise, they need replacement.
- If you suspect that at least one of the suspension rods is damaged, fix or replace it.
