What needs to be clarified
Separate load, installation and floor flexibility through repeatable manufacturer-permitted operation, without presuming drum failure.
Materials to prepare
- Model-specific installation manual
- Acceleration video identifying programme and load
- Floor plan, foot photographs and specialist access
What to compare
A specialist checks feet, transport locks and clearances against instructions. Permitted trials synchronously record cabinet and nearby floor vibration. Repeat cycles document load, movement and external contact; testing stops if dangerous movement occurs.
Possible outcome of the analysis
A mode log and vibration-path diagram may evaluate checked factors and specify service diagnostics for suspected internal faults, with examination limits stated.
Limits of the conclusions
Spin-up vibration does not prove bearing damage. Different loads or flooring do not automatically reproduce the original complaint.
