Operating instructions

Cleaning the filters in the water
inlet
The machine has the following filters to
protect the inlet valves:
–
in the free end of any water inlet hose
–
in the water inlet valve(s) for connect
-
ing the hose(s) to the machine.
To clean the filter in the inlet hose:
^
Turn off the stopcock.
^
Carefully unscrew the knurled cou
-
pling connecting the inlet hose to the
check valve which is attached to the
stopcock (see "Plumbing").
^
Remove the rubber seal from the re
-
cess.
^
Using pointed pliers, take hold of the
plastic filter bar, remove the filter and
clean.
^
Put the filter and seal back in the re
-
verse order and reconnect the hose
to the check valve. Turn on the stop
-
cock and check the connection is
watertight.
The filters in the inlet hose should be
checked and cleaned approx. every 6
months.
Inspect the inlet hose as it is subjected
to high pressure while the machine is in
operation. The hose should be re
-
placed if there is any sign of damage
such as stress cracks in the surface.
If replacing the inlet hose only use a
hose tested to withstand a pressure of
at least 70 bar. Miele original hoses are
tested to this standard.
To clean the filter in the water inlet
valve:
^ Using pliers, carefully loosen the
ribbed plastic nut on the inlet valve,
and unscrew.
^
Using pointed pliers withdraw the
plastic filter by the bar (see illustra
-
tion).
^
Clean the plastic filter.
^
Put back in the reverse order.
Both filters - one in the pressure
hose union and one in the water inlet
valve must always be replaced after
being cleaned.
