62 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 whether there is sufficient 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 feed water supply in the device has
been set to "INTERNAL".
When using a MELAG water treatment unit:
to c) Set the feed water supply in the
“Settings” menu (function) to
"EXTERNAL” (see Water supply [}page
52]).
63 Very poor feed water quality (conductivity ≥ 65 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.

66 The feed water inflow line between the water
treatment unit and the steam sterilizer has a
leak. Air is also taken in.
When using a MELAG water treatment unit:
Check whether the feed water inflow line to
the steam sterilizer has any leaks and has
been connected correctly.
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 waste water 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 waste water
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.
