A repair enquiry concerns the existing appliance and agreed work. New installation projects are outside this service's stated scope and require a separate suitable arrangement.
What the observation tells you
Replacement can involve different ventilation, furniture-door connections, split ratios and electrical access even when the new unit looks similar. It should not be assumed to be a simple continuation of a repair visit. Compatibility must be assessed before purchase.
A useful next step
Tell the booking team whether you want diagnosis, an agreed repair or replacement installation. Keep the tasks clear so the appropriate provider and preparation can be arranged.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
