Enquiry preparation
Washing machine: keep a short fault diary
For a washing machine enquiry: Record a few ordinary occurrences with the programme and stage. Do not deliberately recreate smoke, tripping, leakage near electricity or uncontrolled movement for a video.
Model and requested work checked before an appointment is agreed.

Apply this to your product
Start with the last wash: did water enter, did the drum turn, and was water left afterwards? Record any warning before discussing the next step.
Why the detail helps
The washing machine 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.
