CLEANING THE COARSE FILTER AND FINE FILTER
It is best to check the COARSE FILTER in the
middle of the fine filter after each wash. If there is
dirt in it, turn it anticlockwise and lift it out. Empty
out the dirt and rinse clean. When replacing the
coarse filter, turn it until it snaps into position.
The FINE FILTER is self-cleaning, i.e. it rinses
itself clean during the course of the washing process.
However, the underside may sometimes need
cleaning. When the coarse filter has been removed,
it is easy to pull the fine filter out. Brush it clean
under running water. Handle with care.
MEASURES TO TAKE WHERE THERE IS A RISK OF FREEZING
If your machine is in a'place where it may be exposed
to frost or left unused for long periods, it should be
protected as follows: .
Turn off the water. Disconnect and drain the inlet
and outlet hoses. Finally empty the inlet valve by
setting a programme and running the machine for a
few seconds.
