A fault occurs...
... if the brewing cycle takes longer than
normal, or
... if the valve of the water reservoir has
become leaky, or
... if the appliance has accidentally
been switched on without water in the
reservoir
the water reservoir needs to be descaled
(see section Descaling).
... if hot water is ejected through the
reservoir lid, or
... if the valve does not open although the
boiling process is complete,
the water reservoir (3 ) has been
overfi lled.
When fi lling the reservoir, be careful to
observe the minimum/maximum water
levels.
