Bosch Cooker hood · your observations
A working light does not tell the fan’s story.
Explain lighting, speed selection and air movement separately. If known, state whether air recirculates through filters or travels through an outside duct. Leave the fitted hood in place; there is no need to climb up or dismantle it.
The fitted air route matters
A recirculating hood and a ducted hood move air through different arrangements. Mention the existing route where known, without removing the unit. A change in sound, fan speed or light response should each have its own sentence.
Speed selection works but airflow seems reduced
Keep sound and air movement separate. The existing filter arrangement, controls and air route can matter to assessment. Do not unmount the hood or reach over an unsafe cooking surface for a closer view.
The result changes between ordinary uses
Keep settings and results from the occasions you already observed. A normal programme between problems adds context, but cannot identify the cause or establish that the difficulty has gone.
When a previous symptom seems to return
Mention earlier work using documents or dates you actually have. Similar behaviour can need a fresh assessment; the same phrase does not necessarily describe the same cause.
When a photograph would help
Use the accessible panel or normal fitted position and check for private paperwork in the frame. Never recreate burning, tripping or dangerous leakage for the camera.
Reading the Bosch label
Where safely available, retain the complete E-Nr and FD from the product label, not just the front range name. Keep the full installed Bosch designation, the actual product type and the existing control arrangement. This name identifies an enquiry route; it does not establish current manufacture, parts stock, replacement compatibility or acceptance of every product.
