c)
The boiler level probe have lime
scales on its end: the machine
does not operate correctly and
water is fed in continuously.
d)
Interruption on wires and on
connection contacts of the level
gauges on the electric panels.
e)
Electronic groups failure.
c)
Disassemble the level probe
and carefully remove lime
scales from the gauge bodies
by means of emery cloth.
Make sure that the
pin/electrode does not rotate
inside the gauge holder, if
necessary screw the upper
nut tight.
d)
Restore continuity on wires
and connection contacts
between level gauges and
electric panel.
e)
Replace one or both the
electronic stations inside the
electric panel.
4.
No water in the boiler with
consequent heating elements
burning due to the failure of the
electronic level control group.
4.
A failure of the level gauges or of
the electronic groups would burn the
heating elements.
4.
Performs the checking
procedure as per pos. 3C.
Replace the level gauges or one
or both the electronic groups.
5.
No water in the boiler due to
a failure of the water feeding
group (electric valve, tubes and
connections).
5.
Causes:
a)
No water from the feeding
system.
b)
The water filter assembled on the
electric feed valve is clogged.
c)
Electric feed valve failure.
d)
Lime scales clog tubes and
connections.
5.
Solutions:
a)
Make sure that water is fed
into the machine by removing
the rubber pipe mounted on
the feeding pipe holder.
b)
Clean the filter net by
disassembling the rubber feed
pipe holder.
c)
Check if the coil of the feed
valve is burned, if so replace
it.
d)
Free and clean tubes and
connections from lime scales.
6.
The pump does not work.
6.
Causes:
a)
The pump rotor is blocked by
scales.
b)
Pump Motor burned.
6.
Solutions:
a)
Try to operate the pump rotor
by rotating the motor shaft by
means of a screw driver
applied into the slit on the
pump motor side. If this fails,
the pump cover must be
disassembled, the brass fan
must be cleaned and the
correct rotation checked.
b)
Replace the pump motor.
BREAKDOWNS ON THE CONDENSATE RECOVER TANK AND ON THE ELECTRONIC
LEVEL CONTROL
(IF EQUIPPED)
1.
No water in the tank, due
to a failure of the water feeding
group (electric valve, connection
tubes).
1.
Causes:
a)
No water from the feeding
system.
b)
The water filter assembled on
the electric feed valve is
clogged.
c)
Failure of solenoid valve to feed
water in the tank.
d)
Discontinuance of electrical
continuity for level probe and
grounding.
e)
Lime scales clog tubes and
connections of tank.
1.
Solutions:
a)
Make sure that water is fed
into the machine by removing
the rubber pipe mounted on
the feeding pipe holder.
b)
Clean the filter net by
disassembling the rubber
feed pipe holder.
c)
Check if the coil of the feed
valve is burned, if so replace
it.
d)
Restore the correct
connection for the level probe
and grounding.
e)
Free and clean tubes and
connections from lime scales.
2.
Water doesn’t reach the pump.
2.
Causes:
a) Failure of solenoid valve to feed
water in the tank.
2.
Solutions:
a)
Check if the coil of the feed
valve is burned, if so replace
it.
