Oven cleaning is a regeneration programme.
If the self-cleaning panels in the oven are no longer
adequately cleaned during normal day-to-day
operation, they will be regenerated with this function.
They will then be fully functional again.
The oven light is switched on.
After 30 minutes the light automatically switches off
again. The oven does not heat up.
