							Thermal cut-out
This machine has a resettable heater
limiter which will shut off the elements in
the event of over-heating. This could be
caused, for example, by large articles
covering the heating elements or if the
filters in the wash cabinet are blocked.
If the fault code:F01 - F03,F18,F19,
F27(water was not heated up in the
wash cabinet and the programme is
taking too long) shows in the display,
proceed as follows:
^Remove the cause of the fault.
^Remove the service panel.
^Press the reset button on the heater
limiter located on the right-hand side
of the plinth.
If this switch trips again, contact the
Miele Service Department.

							Cleaning the drain pump and
non-return valve
If water has not been pumped away at
the end of a programme, the drain
pump or the non-return valve might be
blocked. They are easy to clean.
^Take the filter combination out of the
wash cabinet.
^Release the locking clamp.
^
Lift up the non-return valve and rinse
under running water.The drain pump is situated under the
non-return valve (see arrow).
^Before replacing the non-return
valve, check that the drain pump is
free of obstructions.
^Carefully replace the non-return valve
and secure with the locking clamp.
For safety reasons, the load should
be cleaned and disinfected again.

							Cleaning the filters in the water
inlet
Filters are incorporated in the screw
connection of the water inlet hose to
protect the water inlet valve. If these
filters get dirty they need to be cleaned,
otherwise insufficient water flows into
the wash cabinet.
,The plastic housing of the water
connection contains an electrical
component. It must not be dipped in
water.To clean the filter
^Disconnect the machine from the
mains supply.
^Turn off the stopcock and unscrew
the water inlet hose.
^Clean the large area filter (1) and fine
filter (2), and replace with new filters
if necessary.
^Replace filters and the seal. Make
sure they are sitting correctly.
^
Reconnect the inlet hose to the
stopcock, making sure it goes on
correctly and is not cross-threaded.
Open the stopcock gradually to test for
leaks.
If there is a leak, the inlet hose might
not be on securely or it may have been
screwed on at an angle.
Unscrew and reconnect the water inlet
valve correctly.
