Ub, UE, U6, and related codes mean the washer cannot balance the load well enough to complete the spin. A Ur display usually means it is retrying automatically.
What Ub / UE means
Ub, UE, U6, and related codes mean the washer cannot balance the load well enough to complete the spin. A Ur display usually means it is retrying automatically.
What you may notice
- The timer increases during spin
- The drum repeatedly speeds up and slows down
- The washer shakes or stops
- Laundry is still very wet
Most likely causes
- 01One heavy item is sitting on one side
- 02The drum is overloaded or nearly empty
- 03Items are tangled together
- 04The washer is not level
- 05Suspension components are worn
Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Pause safely
Wait for the drum to stop and the door to unlock before reaching inside.
Redistribute the load
Untangle items and spread them evenly. Pair a single bulky item with a few similar items when care labels allow.
Correct the load size
Remove items from an overloaded drum or add a few compatible pieces to a very small load.
Check that the washer is level
Make sure all feet contact the floor and the cabinet does not rock diagonally.
Know where to stop
Do not steady or move a washer while the drum is spinning. Stop using it if it walks, strikes a wall, or makes a hard banging sound.
When to call a technician or support
Service is appropriate if balanced loads repeatedly trigger Ub or if the empty drum sags, knocks, or moves excessively by hand.
When you call, have the exact product or vehicle model, model year where relevant, the complete code or symbol, and when it appeared.
