Replacing components

The user must replace only the stated compo-

nents

: in case of a fault or for extraordinary mainte-

nance, contact the Dealer, requesting service from an 
authorised technician.

For replacements, always use original spare parts 

to be requested from the Manufacturer

using 

non-original spare parts could cause suboptimal perfor-
mance of the equipment and serious damage to people 
and the equipment itself not recognized under warranty.

Before carrying out any replacement work, it is 

necessary to disconnect the power supply of the 

appliance (by acting on the system switch).
Any replacement must be carried out with the oven 

completely cold and wearing adequate personal 

protection devices (e.g. gloves, etc.).

REPLACING THE DOOR GLASS

REPLACING THE INTERNAL BULB AND GLASS 

 

Fig.44

Before replacing the bulb, 

switch off the power

 to the appli-

ance (acting on the system switch); it is not enough to use the 

ON/OFF 

 key, because bulbs can still be live.

Never tough the bulb glass with your bare hands

; always 

wear gloves. 
Never switch the oven on without having refitted the bulb pro-
tective plate.
