No general compatibility should be assumed. Both manufacturers' clearances, ventilation and fitting requirements must be met.
What the observation means
Replacing one appliance can change the arrangement even if the old combination fitted. A heating problem afterwards may involve installation conditions as well as the hob.
A useful next step
Tell the service team what was changed and retain installation records. New fitting work is separate from this breakdown service's scope. Do not remove barriers or alter cabinet openings yourself to make an incompatible combination appear to fit.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
