... the water container has become harder to put into the
appliance and take out again.
Lightly lubricate the coupling seal on the water container with
silicone grease, as described in "Cleaning and care /
Coupling seal".
... the heating-up phase lasts an unusually long time.
Check the bottom of the water container.
If a thick layer of limescale has built-up, check the water
hardness level that has been set. Set the correct water
hardness level for your water supply (see "Settings / Water
hardness"), and descale the appliance as described in
"Cleaning and care / Descaling".
If the water hardness level was in fact set correctly or the
problem occurs again, contact the Service Department.
... after moving house the appliance no longer switches
from the heating up phase to the cooking phase.
Altitude affects the boiling point of water. If you move house,
the appliance will need to be re-set for the new altitude if this
differs from the old one by more than 300 m. To do this,
descale the appliance (see "Cleaning and care / Descaling").
... during operation an unusually large amount of steam
escapes or steam escapes from parts of the steam oven
where it does not usually.
Check whether
– the door is closed properly.
– the door seal is fitted correctly. If necessary, press it in all
the way round the door to make sure it is fitted evenly.
– the door seal is damaged, e.g. cracks can be seen. The
seal must be replaced with a new one.
If this does not solve the problem, call the Miele Service
Department.
