Additional Details and Usage

Cooking functions and convenience

Keep warm function to maintain dishes at a preset low power level.
Switch-off timer that turns off a cooking zone at the end of a set time (e.g. for boiled eggs).
Count-down timer with acoustic signal at the end of the set time (e.g. for pasta).
Count-up timer showing elapsed time since activation (e.g. for potatoes).
quickStart function automatically selects the cooking zone with cookware when switching on.
reStart function restores previous settings if the hob is unintentionally switched off and switched on again within 4 seconds.

Ventilation operation

Automatic switch-on of the ventilation system when a cooking zone is used.
Sensor-based, fully automatic adjustment of fan power levels via an advanced algorithm.
Three algorithm modes: low-noise oriented, balanced, and performance-oriented.
Automatic delayed shut-off after cooking to remove residual odours (approx. 12 minutes in ducted extraction, 30 minutes in recirculated extraction; can be shut off manually).
Manual fan control remains possible via the dual lightSlider user interface.

Cleaning and maintenance

Grease filter and liquid collector unit can be removed conveniently with one hand via the floating glass ceramics handle.
Large-scale, high-performance stainless-steel grease filters with 12 filtration layers and a black top layer are fully dishwasher safe and heat resistant.
Upper liquid collector unit (200 ml) and lower liquid safety collector (700 ml) are dishwasher safe and easily accessible; the lower collector is detachable from below.
Watertight blower system designed to handle spillages via a powerful drainage system.
CleanAir Plus odour filters are easy to access and remove from above, with filter saturation notifications via the user interface and Home Connect app.

Installation notes

Suitable for ducted or recirculated extraction in four configurations: unducted, partly ducted and fully ducted recirculation, or ducted extraction.
Included accessories support unducted recirculation and allow planning in worktops with depth ≥60 cm.
Installation possible in island and wall-oriented configurations.
Maximum immersion depth is 223 mm below the worktop surface; the appliance must be freely accessible from below.
No false floor required; drawers or shelves in the floor unit must be removable; only a cut-out for the air outlet is needed in the back panel.
For unducted recirculation, a vertical aperture of at least 25 mm behind the back panel is required (50 mm suggested for ideal performance).
For partly ducted and unducted recirculation, a return-flow aperture of ≥400 cm² in the plinth area is required.
Air outlet on the back can be directly connected with a male flat duct element (DN 150); blower is pressure-drop resistant for ducting up to 8 m with three 90° bends.
When installing with ducted extraction and a chimney-vented fireplace, the power supply line requires a suitable safety switch (not required for recirculation).
In ducted extraction configuration, a one-way flap or backflow trap with max. opening pressure of 65 Pa should be installed.
Worktop bearing capacity and stability must be considered, especially with very thin worktops.

Lighting recommendations

For optimal visual appearance of the glass ceramics surface, the use of halogen, LED or daylight light sources is recommended. Neon and energy-saving bulbs are not recommended.

Frequently Asked Questions

Can this hob be installed with both ducted and recirculated extraction?

Yes. The induction cooktop has a fully integrated downdraft extractor and is suitable for ducted or recirculated extraction configurations. It supports unducted, partly and fully ducted recirculation, as well as ducted extraction, with appropriate accessories.

What cabinet size and worktop depth are required?

The hob is suitable for installation into a 60 cm base cabinet. The required niche size is 223 × 750 × 490 mm (H × W × D). The included accessories for unducted recirculation allow planning in worktops with depths of at least 60 cm, and additional kits are available for worktops of 70 cm depth.

How does the automatic ventilation control work?

When a cooking zone is used, the ventilation switches on automatically. Sensors and cooktop data are used to adjust the fan power via an algorithm. You can choose between low-noise oriented, balanced or performance-oriented modes. After cooking, the system can run at ultra low-noise level for a delayed shut-off period to remove residual odours.

Are the filters and liquid collectors dishwasher safe?

Yes. The stainless-steel grease filters, the upper liquid collector (200 ml) and the lower liquid safety collector (700 ml) are fully dishwasher safe and heat resistant. They are designed for easy removal and cleaning.

What smart features are available with Home Connect?

With Home Connect, you can remotely monitor the hob, check whether it is switched off, and access recipes or additional functions via the app. The dish assistant helps you find suitable temperature settings for dishes, and the app provides notifications such as cleanAir filter saturation and convenient re-order options.

What safety features does this hob offer?

Safety functions include 2-stage residual heat indicators, control panel lock, control panel pause (blocking all touch buttons for 30 seconds), a main on/off switch and automatic safety switch-off if heating is not used for a preset time. The product and accessories also comply with specified flammability and needle flame tests.
