Enquiry preparation
Dishwasher: agree the proposed work before choosing components
For a dishwasher enquiry: Ask what labour, parts and further attendance would involve. Website guidance cannot establish that a particular part is needed, available or included in a final charge.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
A dishwasher that never takes in water is different from one that washes then leaves water behind. Keep the last message, whether the programme declared completion and the condition of the dishes in one short account.
The purpose of this detail
The dishwasher reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
What still needs agreement
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
