If the Samsung WF50BG8300 fills and washes but will not spin, work through four things in this order: the door, the drain, the load balance and the level. Samsung's manual is blunt that for safety the washer will not tumble or spin unless the door is closed, that it will not spin while it still holds water, and that an unbalanced load ends in a UB code and a slow or stopped spin. The washer is rated to spin at 1200 rpm, so a drum that will not get up to speed is telling you something is holding it back.
Differential
Likely causes of “Samsung front-load or top-load washer will not spin or leaves clothes soaking wet”, and how to tell them apart
- 1
A door that is not fully closed or has not locked
What separates it The washer fills and washes but never starts the spin, and the display asks for the door to be closed
How to confirm Close the door until it clicks and press and hold Start/Pause; Samsung says the washer will not spin with the door open
- 2
Water still in the drum because the drain filter or hose is blocked
What separates it The drum is wet at the bottom at the end of the cycle and the display shows 5C
How to confirm Follow the drain checks: filter, hose kinks and the 6 to 8 inch hose depth
- 3
An unbalanced load, especially a small one
What separates it The display shows UB or the spin starts and stops repeatedly
How to confirm Redistribute the load by hand; Samsung notes one or two items can unbalance and keep the load from spinning completely
- 4
A washer that is not level on a firm floor
What separates it Spin attempts make the cabinet rock and UB appears again after rebalancing
How to confirm Press down on each corner; Samsung's repair guide says there must be no movement and the leg height is adjusted if there is
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the drum has water in it at the end of the cycle and what the display shows
- What the load was: one or two heavy items, a single large item or a mixed full drum
- Whether the four corners of the washer rock when pressed and whether the shipping bolts were removed
Try in this order
0 of 5 completedStop the cycle and check the door
ReversiblePress Start/Pause to stop the washer, open the door, look for laundry caught in the seal and close the door firmly. The manual says the WF50BG8300 will not tumble or spin unless the door is closed, so press and hold Start/Pause (Hold to Start) to resume.
Empty water from the drum if there is any
ReversibleIf the drum still holds water, work through the not-draining steps for this model: clean the drain filter, check the hose for kinks and make sure it is 6 to 8 inches into the standpipe.
Rebalance the load
ReversibleA UB on the display means the load is unbalanced. Open the door, spread the items evenly, add a couple of towels to a very small load and press Start/Pause (Hold to Start) to resume. Samsung says small loads of one or two items often fail to spin completely.
Check level and the shipping bolts
ReversiblePress down on each corner of the cabinet. If it moves, turn the leveling feet until it does not. Confirm the shipping bolts were removed at installation; a washer still fitted with them will shake and stall in the spin.
Power off and try again
ReversibleIf the cycle still stops, turn the washer off for 2 to 3 minutes, turn it on and run Rinse+Spin with the drum empty. A code that keeps returning after that needs Samsung service.
Model-specific
What is true of this model and not of its siblings
- Spin behavior
- The door must be closed and the drum drained before the WF50BG8300 will spin. UB signals an unbalanced spin; the load can be rebalanced and the cycle resumed with Start/Pause (Hold to Start).
- Motor
- Digital Inverter motor, 10-year part-only warranty. The Repair Guide gives 15 ohms between each pair of motor wires as the technician's test value.
- Tools and supplies
- A bubble level, towels for a very small load and a wide container in case the drum needs the emergency drain.
- Parts for this problem on the WF50A8600 (RepairClinic, 2026-09-20)
- switch door lock, part number DC34-00028A, at $173.20; shock absorber, part number DC66-00470D, at $67.94.

Stop boundary
When this stops being a self-service repair
- !If the drum will not turn by hand with the washer off and unplugged, or a grinding or scraping sound comes from the drum, stop and call service
- !If the display shows 3C (motor) or AC6 (control board communication) and powering off for 2 to 3 minutes does not clear it, contact Samsung service

Exact questions
Common questions
Why does my Samsung WF50BG8300 fill but not spin?+
The manual's own list is a door that is not closed, water still in the drum, an unbalanced load and low power. It will not spin with the door open.
What does UB mean?+
UB is Samsung's code for an unbalanced load during spinning. Rebalance the laundry, make sure the washer is level and on a flat, stable surface, and press Start/Pause (Hold to Start).
Is a wet load at the end of the cycle normal?+
No. Samsung suggests using the High or Extra High spin speed, using HE detergent to reduce suds and checking the drain hose is not kinked or clogged.
Can a small load cause the problem?+
Yes. Samsung says small loads of one or two items can become unbalanced and not spin completely.
What if the door lock light stays on and the door will not open?+
Wait. After a pause the door stays locked for one minute, and after an information code and a drain it stays locked for 3 minutes. If the light is still on after that, power off, unplug and use the emergency drain.
What do 3C and AC6 mean?+
3C is Samsung's motor code and AC6 is the PBA communication code. Power the washer off, wait 2 to 3 minutes, power it on and try again; if either returns, call service.
Does the shipping bolt matter?+
Yes. The manual lists removed shipping bolts among the checks for excessive vibration, and the repair guide asks the technician to confirm the washer is level and does not rock after any service.
Why will this washer not spin with the door open?+
Samsung says that for your safety the washer will not tumble or spin unless the door is closed, so a door that is not fully latched looks like a spin failure.
Should I fill the drum with only one or two items?+
Small loads of one or two items can become unbalanced and not spin completely, so add a few items of similar size or a couple of towels.
What spin speed should I pick for a wet load?+
Samsung suggests the High or Extra High spin speed when a load comes out wet, together with HE detergent to reduce suds.
How do I resume after an unbalanced load message?+
Rebalance the laundry in the drum, then press Start/Pause (Hold to Start) to resume, or power the washer off for 2 to 3 minutes and start again.
Is spinning slower than 1200 rpm a fault?+
Not necessarily. Bedding, for example, has a recommended maximum spin of level 2 or 3, and the washer adjusts spin counts to the load it detects.
