Incident Possible causes What you can do
71 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.
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 (function) to "EXTERNAL” (see Water
supply [}page 52]).
72 Poor feed water quality (conductivity ≥ 40 µS).
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
(DIN 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
filter is exhausted.
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
changed until the water remaining in the
pressure tank has been consumed.
