Enquiry preparation
Tumble dryer: make a short sequence of events
For a tumble dryer enquiry: Describe selection, operation and outcome in that order. Add anything that still responds normally, keeping your observation separate from a suggested failed component.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Name vented, condenser or heat-pump format and describe the last load. Finishing too soon, failing to turn and finishing with damp clothes are distinct observations.
How this supports the discussion
The tumble dryer reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Confirm the proposed attendance
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
