The Miele Waterproof system
Provided your dishwasher has been in-
stalled 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 strict accor-
dance with current local and national
water authority regulations.
– The water used must at least comply
with national regulations for drinking
water quality.
If the water supply has a high iron
content, there is a danger of corro-
sion occurring on items being
cleaned in the dishwasher, as well as
the machine itself.
If the chloride content of the water
exceeds 100 mg/L, the risk of corro-
sion to items being cleaned in the
dishwasher will be further increased.
– 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 backflow preventer is not required;
the dishwasher corresponds with the
applicable standards for the protec-
tion of drinking water.
– The water pressure (flow pressure at
the connection point) must be be-
tween 50 and 1000 kPa (0.5 and
10 bar).
If the water pressure is lower than
this, the fault message
Intake
will ap-
pear in the display (see “Frequently
asked questions”).
If the water pressure is too high, a
pressure reducer valve must be fitted.
– A faucet with a
3
/
4
inch male thread
must be provided on site. The valve
should be easily accessible, since the
water supply should be shut off
whenever the dishwasher is not in
use.
– The DN 10 inlet hose is approx.
59" (1.5 m) long terminating in a
3
/
4
inch female thread. A 59" (1.5 m)
long flexible metal extension hose
tested to 140 bar (14,000 kPa) is
available as an optional accessory if
required. On no account may the inlet
filter or the flow regulator be re-
moved.
