Heat exchanger
This dishwasher is equipped with a heat
exchanger, in which fresh water for the
programme is pre-heated, in order to
save energy. The heat exchanger is re-
filled with fresh water towards the end
of each phase that uses fresh water and
is held there ready for the next part of
the programme.
If you do not wish to use this function it
can be switched off (see "Settings, Heat
exchanger").
If water in the heat exchanger is not
used for several weeks, it will be auto-
matically drained and pumped away for
hygiene reasons. This process takes a
few minutes and will also be carried out
if the dishwasher is switched off or the
door is open.
The display will remain dark. The mes-
sage
Empty accumulat.
will appear in the
display when the
button is pressed.
No other functions are available during
this process.
Automatic drainage cannot be interrup-
ted.
The heat exchanger can be manually
drained for transporting the appliance,
e.g. before moving house (see"Settings,
Heat exchanger").
The heat exchanger should only be
used in conjunction with a cold-fill
dishwasher.
This function should be switched off
if your dishwasher is connected to a
hot water supply.
