Possible cause: The temperature sensor in the oven chamber is defective.
The oven cannot be operated until the defect has been remedied.
Remedy: Replace sensor.
: Core temperature probe defective or wrongly fitted
Possible cause: Probe is not fitted in socket. Probe defective, socket for probe defective or short-
circuited (due to water or fat).

require the use of the steam generator can still be used.
Remedy: Replace heating element with sensor.
: Condensation sensor defective
The oven can still be operated even if the defect is not remedied. However, the temperature in the
drain will exceed 60°C and the defect should therefore be remedied as soon as possible.
Remedy: Replace sensor.
: Water shortage in steam generator
The maximum water level in the steam generator has not been reached after 2 minutes of filling.
Possible cause: Solenoid valve or dirt filter clogged, water supply blocked or water pressure too

water pressure is min. 1.5 bar.

The temperature of the upper heating element in the steam generator is above 130°C.

The program cannot be used until the defect has been remedied.
Remedy: Stop the oven for approx. 5 min., then resume the program that was interrupted.
: Breaking of phase
Possible cause: One or more phases in the power transmission to the oven is lacking, possibly due
to a defective fuse. The program cannot be used until the defect has been remedied.
Remedy: Check switchboard. Replace defective fuses, if any.
