Fabric thickness, quantity and initial moisture can change the drying task. Comparing a few thin shirts with a packed towel load can make normal differences appear to be a new fault.
Understanding this situation
The programme and dryness target also need to match for a meaningful comparison. Use observations from ordinary suitable use, not repeated experiments with unsafe loads or a machine already showing concerning signs.
A useful next step
When reporting a change, describe the earlier normal load and the current one as closely as possible. Include spin setting and drying option. This gives context without claiming that timing alone proves a failed component.
