EcoTech Heat exchanger
This dishwasher is equipped with a heat
exchanger in which fresh water for the
rinse cycle 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 program.
If you do not wish to use this function it
can be switched off (see "Settings -
EcoTech 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 system
will appear in the
display when the
button is pressed.
No other functions are available during
this process.
Automatic drainage cannot be inter-
rupted.
The heat exchanger can be manually
drained for transporting the appliance,
e.g. before moving house (see"Settings
- EcoTech Heat exchanger").
The heat exchanger should only be
used in conjunction with a cold-fill
water supply.
This function should be switched off
if your dishwasher is connected to a
hot water supply.
