Problem Possible Reason The Solution
A heating element is
damaged and/or over-
heated.
Switch off immediately, unplug and leave the appliance
cool down.
– Check, if the air flow in the oven is obstructed via lar-
ge parts or sheats of tin foil or baking paper.
– Check, if any cooking dishes (e.g. for cake or gratin)
or any pieces of tin foil are too close to a heating ele-
ment or even touching a heating element. Ensure to
keep a distance of at least 3cm.
– If in doubt, send the appliance to an authorized service
centre for examination and repair.
Do not use the appliance again if any type of
malfunction occurs.
The oven lamp within
the oven compartment
remains dark, even during
operation.
The oven lamp is swit-
ched off.
At each step of operation, you can switch the oven lamp
on and off at will. With the key area locked during ope-
ration, touch the lock button
until a beep sounds, to
unlock the operating elements. Then touch the light but-
ton to illuminate the oven compartment.
Standby mode has been
activated, switching off the
oven lamp automatically.
If required, press the on/off button
and thereafter
the light button
to switch on the oven lamp again.
The oven lamp is out of
order.
Replace the oven lamp. Select the correct light bulb type
suitable for high temperature applications (see: ‘Repla-
cing the Oven Lamp’). If in doubt, take the appliance to
an authorized electrician for exchanging the light bulb.
You have replaced the
light bulb of the oven
lamp, but it burnt out
again in a very short time.
The light bulb has not
been suitable for high
temperature application.
Do not use common light bulbs for the oven
lamp! For usage within an oven, special high tempera-
ture light bulbs are required (see: ‘Technical Specifica-
tions’ and ‘Replacing the Oven Lamp’).
The bulb of the new lamp
has been polluted.
Fat and other pollutants on the bulb burn in, blacken the
bulb, and therefore cause overheating and reduce the life-
time of the lamp. Do not touch the bulb of the new lamp
with your fingers.
The oven switched off
automatically, although
the cooking time did not
elapse completely.
You have forgotten to re-
assume operation after
switching to the pause
function.
With the program interrupted and no buttons pressed, the
oven waits approx. 3 minutes for you to resume opera-
tion by touching the start/pause button
. Thereafter,
the oven cancels operation automatically to avoid unnecessa-
ry energy consumption, if you have forgotten to switch it off.
Problem Possible Reason The Solution
Condensate is accumula-
ting at the interior of the
oven door window and
hot air is coming out.
Depending on the type
of food your are baking,
during operation steam
may escape and conden-
sate on cooler parts of the
appliance.
This is normal. No need to do anything. After some
minutes of operation, the condensate will evaporize.
The rotisserie spit is not
turning.
The wrong program is
running.
Touch the start/pause button
for pausing the run-
ning program. Then, via the selection dial, select one of
the rotisserie programs: (Air Fry) or
(normal
convection). If required, set the temperature and baking
time and start the program.
The rotisserie spit is
blocked.
Switch off the oven immediately and remove the obstacle.
Always ensure that your food does not touch
the heating elements or any other parts within the oven
during grilling. It may not get loose, when the rotor is turning.
Your food has some
burnt areas, although you
selected time and tempe-
rature correctly.
Your food is placed too
near to the heating ele-
ments AND/OR the pieces
of your food are too large.
Always ensure to keep an appropriate distance of at least
3 cm (1-2 inches) to the heating elements.
– With very high temperature settings, you should leave
somewhat more free space to the heating elements:
e.g. use another shelf slot. Try to position your food in
the centre of the oven as far as possible.
– Cut smaller pieces and, if required, bake your food in
portions.
– Ensure that the correct combination of heating ele-
ments and convection is selected. May be, you should
try normal convection instead of an Air Fry function.
– In the lower part of the oven, a better distribution of
heat is reached, when inserting the baking tray in the
bottom shelf slot.
– Select a lower temperature and, if really required, a
higher baking time.
– Distribute a little cooking oil on your food, before baking.
You set the baking time
according to a conventio-
nal oven.
In many cases, the Design Oven Air Fry & Pizza bakes
your food much faster than a usual oven. Check your
food in time (see: ‘Tips for Best Results’).
The consistency of your
food is very inhomoge-
nous.
Dry food or food with a lot of sugar or proteins are brow-
ning much faster than fresh, moist or greasy pieces. Pre-
pare your food accordingly (see: ‘Tips for Best Results’).
