n° TROUBLE CAUSE REMEDY
9 The bowl does not open, even
operating
by hand on
emergency ball valve BV1
(Tab.21), which substitute
solenoid valve YV1.
Shortage of water: see at
trouble 7) - shortage water line.
See at trouble 7). Enlarge water
line inserting a large diameter
pipe and/or installing a surge
tank.
Worn-out gaskets of bowl
valves (Tab. 03).
Clean bowl valves and replace
gaskets.
10 The bowl does not open,
opening takes place only
operating by hand on
emergency valve BV1 (Tab.21)
Non opening of solenoid valve
YV1 due to:
which substitute solenoid valve
YV1.
- cycle disconnected; Activate cycle.
- solenoid valve broken or
obstructed by limestone.
Clean or replace solenoid valve
and check hardness of water.
- wrong electrical connection
to the solenoid valve
Check the connection.
- not correct calibration of
timers T2, T3, T4.
Regulate times.
- the PLC has a problem Check the PLC exit Y1. If the
corresponding warning light is
lighted contact our technician.
Worn-out gaskets of bowl
valves (Tab. 03).
Replace gaskets.
11 The
bowl does not open
correctly.
Not correct calibration of
metering device (if present) due
to:
- Insufficient quantity of water
line.
Regulate the necessary water
capacity
screwing the
regulation screw (see Tab. 05 -
05.340.0).
- Low air pressure Check (RPD and RPA) and the
3-way solenoid valve (YV31)
Insufficient pressure and/or
capacity of water line.
Check and provide: pressure
must be higher than 2 bar.
Enlarge water line inserting a
large
diameter pipe and/or
installing a surge tank.

Pressure reducer out of
calibration.
Regulate pressure at 2,5 bar.
