Incident Possible causes What you can do
67 Only when using a water treatment unit:
The waste water cannot flow off. A rinse
must be performed after a further 2 or 3
program runs.
a) The outlet hose is kinked or installed
sagging.
b) The siphon or the building-side waste
water line is blocked.
c) The Quick-Program B and S are mainly
used. These programs do not do not have
automatic rinsing.
a) Check the installation of the outlet hose.
This must be installed without kinking or
sagging and at a constant decline.
b) Check whether the building siphon is
blocked. Please note: If multiple devices are
operated simultaneously, we recommend the
installation of an additional siphon.
c) Start another program e.g. the Universal-
Program, Gentle-Program or Prion-Program
to perform the necessary rinsing.

of the internal storage tank (feed water) is
stuck.
When using a MELAG water treatment unit:
c) The water supply is set to INTERNAL"
despite external water supply.
When using the internal storage tank:
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) Set the feed water supply in the
Settings menu to EXTERNAL (see Water
supply [}page55]).
72 Poor feed water quality (conductivity ≥ 40µS/cm).
When using the internal storage tank:
a) Water of insufficient quality e.g. tap water
was used.
a) Empty and clean the right-hand chamber
of the internal storage tank (feed water side)
and fill it with water of the required quality
(EN13060, AppendixC).
When using a MELAG water treatment unit:
b) MELAdem40: The mixed-bed resin
cartridge is exhausted.
c) MELAdem47: The mixed-bed resin
cartridge, the pre-filter or the activated coal

b) MELAdem40: Replace the mixed-bed
resin cartridge in accordance with the
applicable operating manual.
c) MELAdem47: Replace the mixed-bed
resin cartridge and if necessary, the pre-filter
and activated carbon filter in accordance with
the applicable operating manual. Empty the
pressure tank (if possible until it is half full)
and wait until it has been filled again. An
empty pressure tank requires c.1 hour to fill.
Please note: The notification may also
continue to be shown after the filter has been
