Not every malfunction can be ascribed to a defect
of your cooker. If your appliance should not function
properly, search for the fault in the list below. If you
are not successful in remedying the fault with the
aid of the list below, then contact your Gaggenau
after-sales service.
The cooktop does not work
Check that the household fuses for the appliance
are OK. Check if there has been a power cut.
The cooktop cannot be switched on. The main
switch flashes repeatedly when touched.
An object lies on one of the sensor keys (e.g. a dish
cloth). Remove the object and switch on the
cooktop as usual.
The cooktop functions but does not heat up. A
spot lights constantly on the timer display.
The cooktop is on show room mode after
installation. Disconnect the cooktop from the power
supply for at least 10 seconds. Reconnect the
cooktop and within 3 minutes carry out the
following procedure:
1 Switch on cooktop at main switch l. Timer
must be off.
2 Touch the symbol d and keep the finger
pressed down. Within 3 seconds touch and
release the main switch l. The cooktop
switches off.
3 Remove your finger from the symbol d. A signal
will sound. The spot on the timer display goes
off.
The cooktop has switched itself off
The main switch was touched accidentally. Switch
the cooktop back on.
A cooking zone has been in constant operation for
too long. The safety deactivation was activated.
Switch off the cooking zone. It can be switched on
again immediately.
Er display and numbers
If an Er and numbers appear on the display, there is
a fault with the electronics. Switch the cooktop off
and, after a few minutes, on again using the
household fuse or the circuit breaker in the fuse box
(reset). Disconnect the cooktop from the electricity
and call the after-sales service if the display
appears again.
Alternating K and 7 display
A cooking zone which is set on level 8 or 9 is too
hot. This cooking zone is reduced to level 7. When
K disappears you can select a higher setting again.
K display
The cooktop is too hot and has switched itself off.
Remove the pots from the cooking zones.
K disappears from the display when the cooking
zones have cooled sufficiently.
Wait a few minutes until the cooking zones have
cooled down slightly. If K appears again after the
cooking zones are switched back on, the cooktop is
still too hot. Switch off the cooking zones and allow
to cool further.
F1 display
A cooking zone has faulty electronics.
Switch the cooktop off and, after a few minutes, on
again using the household fuse or the circuit
breaker in the fuse box (reset). Disconnect the
cooktop from the electricity and call the after-sales
service if the display appears again.
F4 display
The control panel is too hot and the cooktop has
switched itself off. Check whether there is a hot
pan on the control panel.
Remove the pan from the control panel. Wait a few
minutes until the control panel has cooled down
slightly. If F4 appears again after the cooking zones
are switched back on, call the after-sales service.
