Repair guidance / Mercury / BR5
A warning appears when cooking starts
Copy the exact code and note whether one zone or the whole hob is affected. Include the sequence between pan placement, control selection and warning. Similar code formats on different product families must not be treated as an interchangeable diagnosis.
A different pattern: the supply protection operates
Switch off and stop use if the hob trips a protective device. Tell us whether the event happened immediately, during a setting change or after a period of cooking. Never bypass protection or repeatedly reset it to keep the hob running.
Equipment sharing space with other fittings
Mention stacked equipment, adjacent storage or a cupboard arrangement that limits access. An external picture can be useful. Leave the surrounding fittings in place until the person assessing the job confirms what access is required.
Identify this Mercury model
Include the full model, fuel type, serial number and which oven, hob zone or control has failed. Gas work and engineer qualification must be confirmed before acceptance.
A clear Petts Wood repair brief
Use the complete BR5 postcode for the Petts Wood address. Write the displayed error exactly, including spaces or leading zeros where present, and distinguish it from the appliance model. Those two identifiers serve different purposes.
Questions for this repair enquiry
What details help with “a warning appears when cooking starts”?
Keep the last successful operation separate from the first sign of the problem. For a report of “a warning appears when cooking starts”, say what still works and what no longer happens. If the other pattern, “the supply protection operates”, has also occurred, include its timing as a separate observation. Send these details with the full model and your Petts Wood postcode; they prepare the enquiry without identifying a part in advance.
How does “the supply protection operates” change the enquiry?
Treat that as additional evidence rather than proof that both symptoms have one cause. Explain whether the two patterns began together or appeared at different times. Include the fitting context — equipment sharing space with other fittings — so the assessment can account for safe access as well as the reported behaviour.
