20.2 Replacing the oven light bulb

the oven light bulb.
Note: Heat-resistant, 40-watt, 230 V halogen bulbs are
available from the after-sales service or specialist retail-
ers. Only use these bulbs. Hold the new halogen bulbs
only with a clean, dry towel. This increases the service
life of the bulb.

WARNING ‒ Risk of electric shock!
When changing the bulb, the bulb socket contacts are

is switched off in order to prevent a potential electric
shock.
Also unplug the appliance from the mains or switch
