Samsung groups 8C with MEMS-sensor errors. It is a different code family from Ub/Ur imbalance; do not assume rearranging one load repairs it.
Samsung washers whose own manual identifies the displayed code with the meaning below. Codes can differ by generation; this is not a universal parts diagnosis.
Wait for motion to stop and the door or lid to unlock. Water may be hot. Isolate power and follow the exact manual before any user filter maintenance. Never open a filter against a full drum, force a lock or bypass an interlock.
Compare the behavior
A movement-related sensor message and a balance retry can coexist with shaking, but they are not synonymous. Preserve the code distinction before attributing everything to the load.

Code-specific checks
Document the move
Record whether the washer was moved, installed or serviced immediately beforehand. Observe external stability and obvious installation changes without dragging a full or stacked washer. The timing supports a service history, not certainty that a sensor was physically damaged.
Compare 8C with Ur
A balance retry and a sensor error answer different questions. Ur describes another balancing attempt; 8C is a sensor-related fault category. Preserve the exact display rather than reporting both as unbalanced. Do not buy suspension rods solely because the washer also shook.
Where owner checks stop
Use only the owner-manual restart instruction. If the code returns, stop testing and arrange service. Sensor, mounting, wiring and control checks need the appropriate model documentation; opening the cabinet is not necessary to provide the technician with good observations.
If the warning returns
Check safe external installation; recurring 8C needs sensor-system diagnosis.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
