Frequently Asked Questions (FAQs)

How the hob reacts	Cause	Solution to problem
The hob detects pans that are standing closely together as just one pan, and in the display it indicates fewer pans than are standing on the hob.	The user turns the hob on when the pans are already standing on the hob and are positioned very closely together.	Lift up the pans one after the other and wait until the hob responds to this (pan display moves or appears in dotted form) before putting them back down again. Or move the pans apart.
The hob cannot detect which pan is where and clears all the settings apart from one. It's not possible to tell which this will be. Depending where the pans are repositioned, the hob detects a single pan where there are more than one.	The user is moving more than one pan at a time.	Lift up the pans one after the other and wait until the hob responds to this (pan display moves or appears in dotted form) before putting them back down again. Only move one pan at a time.
Not all the pans that are standing on the hob are shown in the display.	Either not all the pans are suitable for use with induction hobs or two pans were moved at the same time.	Use pans that are suitable for use with induction hobs. Only move one pan at a time.
The display suddenly shows two pans, one above the over.	The user is tilting the pan, e.g. when stirring a sauce, then standing it back on the hob. The hob thinks that when a pan is tilted it's being moved. When it's put back down flat, the hob thinks that a second pan has been placed next to the first pan and so shows a second pan in the display.	Lift up the pan and wait until only one pan is shown in the display. Then set the pan down on the hob.
Two pans with the same size are shown with different sizes on the display.	Depending on the magnetic bottom side of the pan and the position of the pan it can cover 4-7 coils. The appliance cannot exactly detect the size of the pan.	Lift up the pan and set it up again Check if the whole bottom side of the pan is magnetic

Loss of Performance and Functionality

The appliance does not have enough power, and often indicates that maximum power has been exceeded.

The appliance originally had a 2-phase connection and then a 3-phase connection. As a consequence, power consumption was limited to 7,400 W.

Solution: In the user settings, under Assistance functions, increase the power consumption to 11,100 W.

The GourmetGuide functions are not working properly (temperature is too high).

The user moves a pan that is using the GourmetGuide function (melting, keeping warm, reheating, simmering). It takes a certain amount of time for the temperature sensors below the glass to measure the correct temperature. During this time, the temperature in the pan can go up.

Solution: Pans being used with a GourmetGuide function should not be moved.

Within minutes of cooking, the fan is already running at full power. The fan is loud.

The kitchen cabinet provides insufficient ventilation.

Solution: When cooking, open the drawer below the hob slightly. Have your cabinet fitter rectify the problem.

It is not possible to operate the appliance and the user cannot switch off the demo mode.

The appliance was delivered with the demo mode activated.

Solution: In the user settings, under Service functions (code 6301), uncheck the demo mode option.

No good heat distribution

Coils that have bad coverage have to be shut down because of EMV regulations. Depending on the position the coverage can be better or worse. Pans without aluminum core (for example Iron cast pans) have worse heat distribution.

Solution: Replace the pan to another spot (not just a slight movement)
Use pans with bigger and permanent aluminium cores (induction compatible)

Reference water boiling speed

Pan: WMF without cover, Diameter = 150mm
Volume: 1 liter of water, 10°C to boiling point
Coils: 3 coils running (green)
Time: approx. 4min

Maximal power per phase

GK11TIFKZ(S) (31062) & CTI6T-31134: 3.7 kW per one-third at 11.1 kW.
At 7.4 kW connection, 3.7 kW each half

GK11TIXFKZ (31093) & CTI6T-31132: 7.4 kW on the whole cooking hob

Installation Errors

Issue	Description/Cause	Solution
Scratches on the bottom side of the glass after removing the sealing bead	The color got removed with the knife	Don't remove the sealing bead or do it with the fingers and without other tools
Connection cable and drawer getting caught	Cable is not installed correctly	Put the connection cable and LAN cable into the brackets
