6. Fault messages
A fundamental difference is made between two types of fault:
♦ Faults which permit further use
(fault is limited to cooking zone(s) or module)
♦ Faults which do not permit further use
(fault has an effect on the entire hob)
6.1 Cooking zone
The fault where the temperature sensor on the coil is defective (sensor breakage or sensor short-circuit)
can occur on one single cooking zone. If this is the case, the power to the corresponding cooking zone
is switched off (cooking level > 0) and an F appears in the actuator display corresponding to the cooking
zone. No fault is indicated if the cooking zone is switched off.
The other cooking zones can continue to be used.
6.2 Module
The fault where the pulse for the mains-synchronising activation and deactivation of the cooking zones
is not available can occur on one module. If this is the case, the power to the corresponding cooking
zone (cooking level > 0) is switched off and an F is shown in the actuator display corresponding to the
module. No fault is indicated if the cooking zone is switched off.
The other module can continue to be used.
6.3 Hob
The faults listed below result in the hob not being able to be used. If the fault is already known when the
main switch button ON is activated, the fault code is then displayed. If the fault occurs during use, all
cooking zones are switched off and the fault code is displayed.
Faults which affect the entire hob are indicated in the following form:
The display goes off after 10 seconds or if the main switch button OFF is activated before expiry of the
time.
