MAINTENANCE OF THE BOILER
According to the hardness of the water and the number of
selections made, a periodic descaling of the boiler is
necessary.
This operation should be carried out by qualified
technicians only.
To descale the boiler, it is necessary to remove it from the
machine.
For descaling use only biodegradable, non-toxic and mild
products.
Thoroughly rinse all parts before reassembling.
When reassembling make sure that:
- the electrical contacts (terminals, fastons etc.) are thor-
oughly dry and correctly connected;
- the safety and anti-boiling thermostats are suitably posi-
tioned and fastened;
- the hydraulic connections are correctly made.
IMPORTANT NOTICE!!!
If for any reasons the heating system of the boiler is
operating without water, check the correct function-
ing of the boiler temperature sensor before restarting
the machine.
If dry heating continues until the safety thermostat is
activated (see hydraulic system) the boiler temperature
sensor could be damaged permanently and therefore
need to be replaced;
a thorough check of all components of the system (pump,
boiler heating element, tubing etc. in indispensable in any
case.
