Trouble shooting
Notes
–
Each time the mains power is switched on or
following a power failure, a sound is produced
when the gas valves are started up. The illuminated
rings around the control knobs will be lit green for a
few seconds and then turn yellow. Wait until the
illuminated rings switch off.
–
When the gas cooktop is switched on, the
electronics open up the gas supply, which
produces a short sound. A sound can also be heard
when the setting is changed. This is normal.
Demo mode
The demo mode is activated if all of the illuminated rings
around the control knobs light up white for 10 seconds
after switching on the appliance. The burner does not
ignite. The illuminated ring around the active control
knob lights up orange.
You can deactivate the demo mode as follows:
1
Turn all of the control knobs to 0. Disconnect the
appliance from the mains power supply. Wait at
least 30 seconds.
2
Reconnect the appliance. The illuminated rings
around the control knobs light up green for a few
seconds and then turn yellow. Wait until the
illuminated rings switch off.
3
Then deactivate demo mode within three minutes as
follows:
Turn any of the control knobs anti-clockwise to
position 12.
4
Turn the control knob clockwise to position 1.
5
Turn the control knob anti-clockwise to position 0.
Wait until the illuminated ring lights up yellow.
6
Turn the control knob clockwise to position 1. The
illuminated ring lights up green.
Wait for five seconds. The illuminated ring now
turns yellow.
Demo mode has now been deactivated.
To save the
setting, always exit the menu as follows:
7
Turn the control knob to 0. Then turn the control
knob anti-clockwise to position 12. Turn the control
knob clockwise to position 1. Turn the control knob
anti-clockwise to position 0. Wait until the
illuminated ring goes out.
The appliance panelling becomes
slightly raised at the corners when it is in
operation.
The metal from which the cook-
top is made expands as it heats
up.
This is normal. It will contract again once it has
cooled down.
