Fault
Possible cause
Troubleshooting
Baking tray/universal pan
warped, bent, bounces
Not a fault.
Improper use.
-
If cold or frozen food is placed onto a hot (preheated) baking tray, the great
difference in temperature can cause sudden and strong deformations of the baking
tray/universal pan.
-
Strong and sudden deformations of the baking tray/universal pan may also occur if
the baking tray/universal pan is removed from the cooking compartment with food
on it while still hot and set down onto a cold surface.
-
These deformations are not reversible.
-
Examples of cold food items are frozen pizza, frozen bread rolls or even cold water.
-
Deformed baking trays remain warped, or warp when the temperature increases.
-
There are no baking trays or universal pans that are resistant to such great
differences in temperature and that do not warp.
► Advise customer:
To prevent permanent deforming of the baking tray, only place cold or frozen food
onto a cold baking tray
Remove the baking tray from the appliance before pre-heating it.
Please note that only hot liquids may be placed on a hot baking tray (heat liquids
first).
Alternatively, a wire rack with greaseproof paper or a glass tray can also be used.
Do not set a hot baking tray/universal pan down onto a cold surface.
