5.7 ANTI-SUCTION VALVE
The anti-suction valve ensures that air
enters the heater during the machine cool-
ing phase. In this way the reduction of
water volume due to cooling does not
create decompressions that may give rise
to drawbacks such as the suction of milk
through the steam wand.
WHEN TO REPLACE
You can assume that there are problems
with the anti-suction valve when:
•
There is a strong smell of rot when mak-
ing steam or water is extracted from the
heater.
•
The water leaving the heater is dirty.
In these cases the valve is closed and is
locked in this condition.
If the valve blocked open because of lime-
stone the signs would be:
•
A continuous slight whistling sound com-
ing from the valve.
•
Condensation drops near the valve.
NOTE
We suggest that the valve (A) be
replaced annually to ensure proper
function and excellent sealing wand.
WARNING
Operation to be carried out with the
pressure in the boiler at zero (0 bar).
HOW TO REPLACE
Using a 19 mm cup hex wrench unscrew the
valve from its housing.
When inserting the new one, coat the
threads with Teflon tape or with a few drops
of Loctite.
