Warning! Repairs to the appliance are only to be carried out by qualified service
engineers. Considerable danger to the user may result from improper repairs.
If the appliance has been wrongly operated, the visit from the customer service
technician or dealer may not take place free of charge, even during the warranty
period.
Advice on cookers with metal fronts:
Because of the cold surface at the front of the cooker, opening the oven door
during (or just after) baking or roasting may cause the glass to steam up.
