Enquiry preparation
Washer-dryer: make a short sequence of events
For a washer-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
Tell us whether the wash completed before the drying difficulty. Include dry-only or combined selection, load and any remaining water rather than simply saying the machine is cold.
How this supports the discussion
The washer-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.
