• Clean the water inlet filter (35 or 14): refer to what has been explained previously.

an authorised assistance centre to buy the new filter.

It is normally enough to put the pin (24) supplied through the hole of the nozzle to
clean it. If the results are not good, replace the nozzle purchasing it from an authorised
assistance centre.
The nozzle can be replaced using a 14 mm box spanner (not supplied).
