Bosch NIT8665UC Cooktop
Frequently Asked Questions (10)
What cookware is compatible with the NIT8665UC induction cooktop?
Only ferromagnetic pans are suitable for induction cooking, including enamelled steel, cast iron, and special stainless steel utensils designed for induction cooking. You can check if your pan is compatible by testing whether a magnet is attracted to the base. Pans made of thin normal steel, glass, clay, copper, or aluminum should never be used. (Page 9)
What does it mean when the power level flashes on an element display after I place a pan on it?
A flashing power level display indicates that no pan is present, the pan is made of unsuitable material, or the pan is not the correct size for that element. Place a suitable ferromagnetic pan on the element to stop the flashing. If you take longer than 90 seconds to place a suitable pan on the element, it will automatically turn off. (Page 9)
What should I do when the error code E2 ("‰ƒ" or similar element overheat error) appears on the display?
The E2 error indicates the element is too hot and has turned off automatically. Remove the pans from the elements and press the display to clear the error once the element has cooled down sufficiently. If the error reappears after turning the element back on, the cooktop is still too hot — turn off all elements and allow them to cool further. (Page 21)
How do I activate the Child Lock to prevent children from turning on the cooktop?
The cooktop must be turned off first, then touch and hold the Clean Lock/Child Lock key until a beep sounds and the D indicator lights up. The cooktop is now locked and cannot be switched on. To deactivate, touch the Clean Lock/Child Lock key again until a beep sounds and the D indicator turns off. (Page 17)
How do I restore the cooktop to its factory default settings?
Factory settings can be restored through the Basic Settings menu, specifically function display "™‹". Turn on the cooktop, then within 10 seconds touch the Timer key until you hear a sound signal, navigate to the ™‹ setting, and select option 1 to return to factory settings. Touch the Timer key for 4 seconds until you hear a sound signal to confirm and save the change. (Page 18)

How do I use the AutoChef™ feature and what pans are required?
AutoChef™ requires a compatible system pan placed in the center of the element — only the Bosch system pans (HEZ390210 small, HEZ390220 medium, HEZ390230 large) are recommended. To activate, select the element, touch the AutoChef key, then choose a frying level using the number keys. Do not place a lid on the pan, as this will prevent the automatic temperature regulation from working properly. (Page 13)
What is the SpeedBoost function and are there any limitations on when I can use it?
SpeedBoost heats large amounts of water faster than the maximum heat level 9 and is available on all elements. However, it can only be activated if no other element in the same group is already operating — if another element in the group is on, the › and Š symbols will flash and the cooktop will automatically revert to heat level 9. In Group 2, the SpeedBoost function may be activated simultaneously for all elements. (Page 15)
How do I safely clean spilled sugar or melted plastic from the cooktop surface?
Sugar, sugar syrup, milk, tomato spills, and melted plastic or foil require immediate removal because failure to do so can permanently damage the surface. While the surface is still hot, use a razor blade scraper held at a 30-degree angle to push the spill off the heated area — wear an oven mitt for protection. After the surface has cooled, remove any residue and apply glass ceramic cooktop cleaner. (Page 20)
Is the NIT8665UC covered under warranty if I have it repaired by a non-authorized technician?
No — if you choose to have someone other than an authorized service provider work on your cooktop, the warranty will automatically become null and void. BSH warrants the product against defects in materials and workmanship for 365 days from the date of purchase, but only when repairs are performed by a BSH-authorized service provider. Authorized service providers are independent entities specifically trained on BSH products. (Page 23)
Why does my induction cooktop make humming, whistling, or crackling noises during operation?
These noises are normal and are a result of induction technology's use of electromagnetic fields to heat cookware. A low humming sound occurs at high heat levels and quiets when the heat is reduced; quiet whistling happens when the cooking vessel is empty and stops once food or water is added; crackling results from cookware made of multiple layered materials vibrating at their contact surfaces. Loud whistling can occur with multi-layered cookware used at maximum output on two cooking zones simultaneously and quiets when the heat level is reduced. (Page 22)
