Cleaning and care
Once the flow of water ceases,
remove the fluff filter completely and
clean it.
Remove any foreign bodies (e.g. but-
tons, coins, etc.) and fluff.
Turn the impeller by hand to check
that it is free to rotate. Any foreign ob-
jects causing an obstruction should
be removed.

Clean the inside of the fluff filter hous-
ing.
Remove any deposits of lime scale and
detergent or foreign bodies from the
thread of the filter housing and filter unit
(as these objects can cause a leakage
of water).
Replace the fluff filter and screw it in
tightly.
