13 Malfunctions
72
Incident Possible causes What you can do
74 Poor feed water quality (conductivity ≥ 40 µS/cm).
When using the internal storage tank:
a) Insufficient feed water in the right-hand
chamber of the internal storage tank.
b) The float switch of the right-hand chamber
of the internal storage tank (feed water) is
stuck.
a) Check the water level of the feed water in
the right-hand chamber of the internal
storage tank and refill with feed water if
necessary.
b) Check the float switch as follows:
1. Remove the tank lid from the storage tank.
2. Remove the filling funnel if present.
3. Move the float in the right-hand chamber
of the storage tank (feed water side from
below in the tank) up and down repeatedly to
restore its free-movement.
When using a MELAG water treatment unit:
c) The water supply is set to INTERNAL
despite external water supply.
When using a MELAG water treatment unit:
c) Set the feed water supply in the
Settings menu to EXTERNAL (see Water
supply [}page55]).
75 When using the internal storage tank:
a) Insufficient feed water in the right-hand
chamber of the internal storage tank.
b) The float switch of the right-hand chamber
of the internal storage tank (feed water) is
stuck.
a) Check the water level of the feed water in
the right-hand chamber of the internal
storage tank and refill with feed water if
necessary.
b) Check the float switch as follows:
1. Remove the tank lid from the storage tank.
2. Remove the filling funnel if present.
3. Move the float in the right-hand chamber
of the storage tank (feed water side from
below in the tank) up and down repeatedly to
restore its free-movement.
When using a MELAG water treatment unit:
c) The water supply is set to INTERNAL
despite external water supply.
When using a MELAG water treatment unit:
c) Set the feed water supply in the
Settings menu to EXTERNAL (see Water
supply [}page55]).
76 a) The Quick-Program B and S are mainly
used. These programs do not do not have
automatic rinsing.
With connection to the building waste water
outflow:
The waste water cannot flow off. A rinse
must be performed after a further 2 or 3
program runs.
b) The waste water hose is kinked or
installed sagging.
c) The siphon or the building-side waste
water line is blocked.
a) Start another program e.g. the Universal-
Program, Gentle-Program or Prion-Program
to perform the necessary rinsing.
With connection to the building waste water
outflow:
b) Check the installation of the waste water
hose. This must be installed without kinking
or sagging and at a constant decline.
c) Check whether the building siphon is
blocked. Please note: If multiple devices are
operated simultaneously, we recommend the
installation of an additional siphon.
78 a) The left-hand chamber of the internal
storage tank (waste water) is full or was only
incompletely emptied.
b) If the notification is displayed despite an
empty tank, the float switch is blocked.
a) Empty the left-hand chamber of the
storage tank (waste water).
b) Check the float switch as follows:
1. Remove the tank lid from the storage tank.
2. Remove the filling funnel if present.
3. Move the float in the left-hand chamber of
the storage tank (feed water side from below
in the tank) up and down repeatedly to
restore its free-movement.
