Photograph labels clearly
Keep the complete appliance in one photograph and the accessible model label in another. Do not remove the unit or obscure an existing A Brassett service label.
Describe the fault too
A clear label cannot distinguish a switching complaint from a drainage leak. Include the operating method, symptom and first wet or noisy location so the enquiry reaches the appropriate assessment.
A useful distinction
If a badge names a product family but no full reference is readable, keep the uncertainty explicit. A service enquiry can still start with the overall installation and symptom, with compatibility confirmed later.
