Enquiry preparation
Dishwasher: mention a relevant recent change
For a dishwasher enquiry: A moved appliance, interruption or different setting may provide context. Describe what actually happened and avoid treating timing alone as proof of a cause.
Model and requested work checked before an appointment is agreed.

Filling, spraying, heating and emptying are separate stages. Note the last stage you recognised and whether the programme ended normally.
Why the detail helps
The dishwasher 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.
