Use the definition in the model's programme table. Capacity figures commonly refer to a specified dry load, so weighing saturated laundry can give a misleading comparison.
Understanding this situation
Water absorbed by towels or bedding changes weight considerably without describing the original permitted amount. Bulk and fabric restrictions still matter, and a load suitable for one programme may exceed another's limit.
A useful next step
Check the exact model guidance before loading. Do not use a wet weight calculation to justify compressing more laundry into the drum. For a performance enquiry, describe the dry items and programme as accurately as possible rather than relying on a post-wash number.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
