Problem
Food is not adequately
defrosted, heated or
cooked at the end of
the selected cooking
duration.
The microwave function
is working but not the
oven lighting.
Strange noises are
heard when the
microwave oven is
being used.
The time of day in the
display is not accurate.
Food cools down too
quickly.
Cause and remedy
The duration or power level were insufficient to cook
the food.
 Check whether the correct power level was
selected for the duration set.
The lower the power level, the longer the duration
required.
 Check whether the programme has been
interrupted and not restarted.
The lamp is faulty.
You can then operate the appliance as normal, but
not the lighting.
 Contact Miele Customer Service if you need to
replace the lighting.
The food is covered with aluminium foil.
 Remove the aluminium foil.
Sparks are being created by the use of crockery with
a metallic finish.
 Please observe the information on suitable
containers.
The time of day must be reset following an
interruption to the power supply.
 Set the correct time of day.
In the microwave oven, food begins to cook from the
outside first, the inside of the food relying on the
slower conduction of heat.
If food is cooked at a high power level, it is possible
that the heat may not have reached the centre of the
food, so it is hot on the outside but cold in the centre.
During standing time heat is transferred to the centre
of the food.
 When reheating food with different densities, such
as plated meals, it is therefore sensible to select a
lower power level and lengthen the duration
required.
