Frequently Asked Questions - KIH 8645-6B Kernau

What type of cookware can I use on this induction hob?
Only cookware with a magnetisable base, such as cast iron, stainless steel with magnetic base, or enamelled steel. Avoid copper, aluminium, glass, and ceramic. The base must be flat and at least 110 mm in diameter.
How do I activate the Power Boost function?
Place suitable cookware on the zone, then slide your finger all the way to the right on the slider until 'P' appears. The boost activates for a maximum of 5 minutes before automatically reducing to the highest normal level.
What does the residual heat indicator mean?
The 'H' symbol appears when a cooking zone is still hot enough to cause burns. It disappears when the temperature drops to a safe level. Use residual heat to keep food warm.
How do I lock the control panel to prevent children from operating the hob?
Press and hold the Control Panel Lock button for 3 seconds. 'Lo' appears in the timer display. To unlock, press and hold the same button again for 3 seconds.
Can I use the hob if the glass surface is cracked?
No. Immediately switch off the appliance and disconnect it from the power supply. Contact customer service. A cracked glass poses a risk of electric shock.
What should I do if an error code like 'HE 54' appears?
HE 54 indicates water or an object on the control panel. Dry the area and remove any items. For other codes like 'HE 1' to 'HE 7', refer to the error table in the manual. If the problem persists, contact customer support.
How do I clean the induction hob properly?
Use a damp cloth or soft sponge without detergent. For stubborn stains, use a glass scraper or a paste of baking soda and water. Avoid abrasive cleaners, steel wool, or scouring pads to prevent scratches.
What is the Maxi Zone function?
It allows you to combine two adjacent cooking zones into a single large zone (e.g., for an oblong fish pot). Press the Bridge Switching button to activate. The power is controlled via one slider. Press the button again to deactivate.
Does the hob require special electrical installation?
Yes. It must be installed by a qualified electrician. The hob requires a 400 V 2-phase connection with a 4 x 2.5 mm² cable and a 16 A fuse per phase. A DC-sensitive residual current device (RCD) is recommended.
How long can the timer be set for?
The timer can be set from 1 to 99 minutes for each cooking zone independently. Use the '+' and '-' buttons to adjust. When the time elapses, a buzzer sounds for 30 seconds and the zone switches off.

Kernau KIH 8645-6B - PRECAUTIONARY MEASURES BEFORE COMMISSIONING - 1

GENERAL SAFETY INSTRUCTIONS

  • The electronics (relay) can cause audible switching noises during operation. The cooling fan may also be audible. The cooling fan can continue to run even after cooking is complete in order to cool the electronic components. These noises are normal during operation and do not constitute a defect in the hob.
  • Switch off the cooking zones after each use.
    • Overheated fats and oils ignite quickly. If you prepare food in fat or oil (e.g. chips), you should monitor the cooking process.
  • When you cook and fry, the cooking zones become hot. Therefore, beware of burns during and after using the appliance.
  • Ensure that no electrical cable from a free-standing or built-in appliance comes into contact with the glass or the hot cooking zone.
  • Never cover the cooking surface with a cloth or protective film; these could become very hot and catch fire.
  • This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.
  • Cleaning and user maintenance must not be carried out by children without supervision.
  • Children should be supervised to ensure that they do not play with the appliance.

Kernau KIH 8645-6B - GENERAL SAFETY INSTRUCTIONS - 1

WARNING:

If the glass surface is cracked, switch off the appliance immediately to prevent the risk of electric shock.

• Metal objects such as knives, forks, spoons and pot lids should not be placed on the induction hob as they could become hot.
- Do not leave the induction hob unattended due to the very fast reaction at high cooking level settings!

Kernau KIH 8645-6B - WARNING: - 1

CAUTION, RISK OF BURNS!

Metal objects such as rings, bracelets, watches etc. can become hot in the immediate vicinity of the induction hob. Non-magnetisable objects (e.g. gold or silver rings) are not affected.

• If there are pets in the home that could reach the induction hob, activate the childproof lock.
- If a pyrolytic oven is installed under the induction hob, the induction hob should not be used during pyrolytic operation. The surface induction hob's overheating protection could be triggered.
- The overheating protection can also be triggered if the surface induction hob is not sufficiently ventilated and/or an inadequately insulated oven installed under the surface induction hob is in operation.

PROTECTION AGAINST DAMAGE

  • Do not use pots or pans with an unpolished or damaged base. These can scratch the glass ceramic plates.
  • Please note that grains of sand can also cause scratches.
    • Glass ceramic is insensitive to temperature shocks and very resistant, but not unbreakable. In particular, sharp and hard objects that fall onto the hob surface can damage it.
  • Avoid touching the edges of the glass pane with pots.
  • Do not use the cooking zones with empty cookware.
  • Avoid placing sugar, plastic or aluminium foil on the hot cooking zones. These materials melt, stick and can cause cracks, breaks or other permanent changes to the disc when it cools down. If such substances nevertheless get onto the hot cooking zones, please switch off the appliance and remove them while it is still hot.

As the cooking zones are hot, there is a risk of burns!

Kernau KIH 8645-6B - PROTECTION AGAINST DAMAGE - 1

ATTENTION:

The cooking process must be monitored! Even a short-term cooking process must be constantly monitored!

Kernau KIH 8645-6B - ATTENTION: - 1

WARNING:

Unattended cooking on a hob with fat or oil can be dangerous and cause a fire!

Kernau KIH 8645-6B - WARNING: - 1

FIRE HAZARD:

Do not store any objects on the hob.

• Never place hot cookware on the control unit. The electronics under the glass could be damaged.
- In order to achieve sufficient ventilation of the electronics in the induction hob, an air space of 20 mm is required under the hob.
An air gap on the front of the kitchen unit is not required.

- No flammable objects (e.g. aerosol cans) may be stored in a drawer under the hob.

- The cutlery trays in the drawer must be made of heat-resistant material.

- Do not heat closed containers (e.g. tins) on the cooking zones. The resulting overpressure can cause the containers or cans to burst, posing a risk of injury!

Kernau KIH 8645-6B - FIRE HAZARD: - 1

PRECAUTIONARY MEASURES IN THE EVENT OF DEVICE FAILURE

• If a fault is detected, the appliance must be switched off and disconnected from the power supply.
• If breaks, cracks or fissures appear on the glass: switch off the induction hob immediately, unscrew the fuse for the induction hob and contact our customer service or your specialist dealer.
- Never open the device itself.
- Repairs to the appliance may only be carried out by specialised personnel.

PROTECTION AGAINST FURTHER DANGERS

- Make sure that the cookware is always centred on the cooking zone. The base of the pan must cover as much of the cooking zone as possible.

- People with pacemakers or implanted insulin pumps must ensure that their implants are not affected by the surface induction hob.

The induction hob must not be switched off, as an electromagnetic field is generated in the vicinity of the appliance when it is switched on (the frequency range of the surface induction hob is 50 kHz).

If in doubt, please contact the manufacturer of the pacemaker or your doctor.

Kernau KIH 8645-6B - PROTECTION AGAINST FURTHER DANGERS - 1

NOTE:

The use of unsuitable pots or adapter discs for induction leads to premature termination of the guarantee.

The manufacturer accepts no liability for any damage that may occur to the induction hob or its surroundings.

CHAPTER 7. CLEANING AND CARE

  • Remove soiling as soon as possible to prevent dirt from burning in.
  • Remove light, not firmly caked-on dirt with a damp cloth or a damp, soft sponge without detergent.
  • Do not use washing-up liquid as it can leave a bluish discolouration.
  • Sometimes stains stubbornly burn onto the hot hob and are difficult to remove. The stains can usually be removed with a glass scraper. Apply the glass scraper evenly over the entire surface and scrape with light pressure. If you don't have a glass scraper to hand, you can also use baking powder: Simply mix baking powder with a little water to form a creamy paste. Then apply the paste to the glass ceramic hob, leave to act briefly and then wipe off again.

- Light, silvery shimmering stains can be caused by aluminium residues from some pots. Such stains can be removed with a glass ceramic cleaning agent once the hob has cooled down.

- Limescale stains are caused by boiling water or pots with a wet outer base. The heat causes the water to evaporate, leaving limescale stains on the glass ceramic. Limescale stains can be removed after the hob has cooled down using a glass ceramic cleaning agent or vinegar.

- Avoid placing sugar, plastic or aluminium foil on the hot cooking zones. These substances melt, stick and can cause cracks, breaks or other permanent changes in the glass structure when cooling down. If this happens anyway, please switch off the appliance and remove these substances while It is still hot.

Kernau KIH 8645-6B - CHAPTER 7. CLEANING AND CARE - 1

CAUTION:

The cooking zones are hot, there is a risk of burning!

- Never use abrasive or scouring cleaning agents, hard sponges, steel wool or stainless steel spirals. Scratches will occur.

Possible causes of scratches

Glass ceramic hobs have a very hard, resistant surface. Should scratches nevertheless occur, the usability of the glass ceramic hob surface is not restricted.

How scratches can occur:

When cleaning vegetables, grains of sand and fine dust get onto the glass ceramic cooktop. If a pot is then placed on the glass ceramic cooktop, the grains of sand can cause scratches.

Pots or pans with an unpolished or damaged base can scratch the glass ceramic panel.

The glass scraper cants under strong pressure or a scraper blade that has broken off at the edges continues to be used. Do not use the hob as a work or storage surface.

CHAPTER 8. SAFETY DEVICES

Protection against overheating

A temperature sensor monitors the temperature inside the induction hob. If an unacceptably high temperature is detected, the induction hob switches off automatically.

Detection of small objects on the surface induction hob

If unsuitable or too small cookware or small items (e.g. knives, forks, keys) are placed on the cooking zones, the appliance switches off after 1 minute. The fan cools the induction hob for a further minute.

Protection through automatic switch-off

This safety protection function switches the induction hob off automatically if you forget to switch off the hob itself. The standard operating times for different power levels are listed in the table below:

Power level(s) Automatic switch-off after
1-3 360 min.
4-6 180 min.
7-8 120 min.
9 90 min.
