Thoroughly inspect the presence of limestone or
oily residues by unscrewing the valve base.
These residues may obstruct the free movement
of water, favouring the stagnation of water in the
filter holder.
NOTE
In the presence of oily residues properly
instruct staff using the machine to perform
regular deep cleaning.
