What this guide covers

Error codes: UB, UE, UR · Symptoms: Won’t spin / keeps going out of balance

This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Safe troubleshooting sequence

Start with the observations and external checks that can be verified without opening energized assemblies. The interactive version asks these in order and changes the path based on your answers.

  1. Check the load distributionSamsung says unbalanced-load codes often mean laundry has collected unevenly in the tub.
  2. Check washer stabilityAn unlevel or unstable washer can reduce spin speed and contribute to imbalance.
  3. Is this happening repeatedly?A one-off Ur retry can be normal; repeated failures on ordinary loads deserve more attention.

What the answers can lead to

Rearrange the load and restart

The current load distribution matches Samsung's documented unbalanced-load condition.

Evidence strength: Strong

Level and stabilize the washer

Samsung specifically recommends checking that all four feet have solid contact with the floor.

Evidence strength: Strong

A one-time Ur retry may not indicate a fault

Samsung notes that Ur can simply indicate the washer is adding water and trying to rebalance the load before spinning again.

Evidence strength: Strong

Repeated imbalance on normal loads needs diagnosis

With load distribution and leveling addressed, repeated failures can require model-specific inspection.

Evidence strength: Moderate

When professional diagnosis is the safer next step

With load distribution and leveling addressed, repeated failures can require model-specific inspection.

Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.

Repair or replace?

A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
