Causes of damage

Caution!

Accessories, foil, greaseproof paper or ovenware on the 

cooking compartment floor: do not place accessories on the 

cooking compartment floor. Do not cover the cooking 

compartment floor with any sort of foil or greaseproof paper. 

Do not place ovenware on the cooking compartment floor if a 

temperature of over 50 ºC has been set. This will cause heat 

to accumulate. The baking and roasting times will no longer 

be correct and the enamel will be damaged.

Water in a hot cooking compartment: do not pour water into 

the cooking compartment when it is hot. This will cause 

steam. The temperature change can cause damage to the 

enamel.

Moist food: do not store moist food in the cooking 

compartment when it is closed for prolonged periods This will 

damage the enamel.

Fruit juice: when baking particularly juicy fruit pies, do not 

pack the baking tray too generously. Fruit juice dripping from 

the baking tray leaves stains that cannot be removed. If 

possible, use the deeper universal pan.

Cooling with the appliance door open: only allow the cooking 

compartment to cool when it is closed. Even if the appliance 

door is only open a little, front panels of adjacent units could 

be damaged over time.
