The Miele Waterproof system
Provided your dishwasher has been
installed correctly, the Miele Waterproof
system will provide extensive protection
against water damage throughout its
lifetime.
Water intake
Water in the dishwasher must
not be used as drinking water!
– The dishwasher must be connected
to the water supply in accordance
with local regulations.
– The water quality should at least
satisfy local drinking water
requirements.
A high iron content can leave to
external rust deposits on the wash
load and the dishwasher itself.
A chloride concentration greater than
100 mg/l in the process water
significantly increases the risk of
corrosion for the wash load..
– In certain regions (e.g. mountainous
regions), the water composition may
cause precipitates to form, requiring
the use of softened water for the
dishwasher.
– A device for preventing the return
flow of water is not necessary, if local
regulations permit.
– The water pressure (flow pressure at
the connection point) must be
between 30 and 1000 kPa (4.5 -
145 psi).
If the water pressure is lower than
this, the fault message
Water intake
will appear in the display (see
“Problem solving guide”).
If the water pressure is too high, a
pressure reducer valve must be fitted.
– A water shut off valve with a
3
/
4
inch
male thread must be provided on
site. The valve should be easily
accessible, since the water intake
should be shut off whenever the
dishwasher is not in use.
– The intake hose is an approx. 1.5 m
(59") long DN 10 pressure hose with
a
3
/
4
“ female thread. A 1.5 m (59”)
flexible metal hose (certified for a
pressure of 14,000 kPa / 2030 psi) is
available as an extension. Do not
remove the dirt filter and the flow
regulator in the screw connection.
