Enquiry preparation
Washer-dryer: read the whole rating label
For a washer-dryer enquiry: Use paperwork or a label that is safely visible in the normal fitted position. Copy product suffixes and service references as well as the large brand name.
Model and requested work checked before an appointment is agreed.

Explain which half of the combined appliance changed. A successful wash followed by damp drying needs a different account from a drum that never drains.
Why the detail helps
The washer-dryer reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Before an appointment is agreed
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
