TROUBLESHOOTING

Maintenance operations must be carried out by an authorised company (e.g. Authorised After-Sales Technical Assistance Cen-
tre).
There can be three possible causes for this anomaly:
Trouble
Smell of gas
Repeated ignition blocks
Irregular combustion or
noisiness
Non-optimal ignition of
first ignitions of the
burner.
Frequent trips of the
overheating safety device
thermostat function.
Siphon blocked
Heat exchanger blocked.
Abnormal noises in the
system
Abnormal noises in the
condensation module
Poor production of
D.H.W.
Red pump LED (UPM3)
Trouble
Low power supply voltage
Rotor seized
Electrical error
66
Possible causes
Caused by leakage from gas circuit pipe-
lines.
No gas. Condensate drain clogged.
Dirty burner, clogged primary heat ex-
changer, incorrect combustion parame-
ters, intake-exhaust terminal not correctly
installed.
The first ignitions of the burner (after cali-
bration) may not be optimal.
Lack of water in the appliance, little water
circulation in the system or blocked pump
(Par. 1.29 - 1.30).
Dirt or combustion products deposited in-
side.
Obstruction of the siphon.
Air in the system.
Air in the module.
Clogged condensing module or D.H.W. ex-
changer.
Possible causes
After about 2 seconds, the LED switches
from green to red and the pump stops.
Powering the pump with the rotor seized,
after about 4 seconds the LED switches
from green to red,
Check sealing efficiency of gas intake circuit.
Check the presence of pressure in the network and that the gas adduction
cock is open. Restore/release the function of the condensate drain,
checking that the condensate has not affected: combustion components,
fan and gas valve. Check the function of the condensate sensor.
Check the indicated components.
The system automatically adjusts the burner ignition until the best
ignition conditions are found.
Check on the pressure gauge that the system pressure is within estab-
lished limits. Check that the radiator valves are not closed and also the
functionality of the pump.
Check that there are no residues of material blocking the flow of
condensate.
Check that there are no residues of material blocking the flow of
condensate.
Check the opening of the cap of the air vent valve (Par. 1.32). Make sure
the system pressure and expansion vessel pre-charge values are within
the set limits. The factory-set pressure values of the expansion vessel
must be 1.0 bar, the value of system pressure must be between 1 and 1.2
bar.
Use the manual air vent valve (Par. 1.32) to eliminate any air present in
the condensation module. When the operation has been performed,
close the manual vent valve.
Contact After-Sales Assistance Service that has procedures to clean the
module or D.H.W. heat exchanger.
Wait for the power supply voltage to rise; when the pump restarts, the
LED will turn green again with a delay of about one second. Note: The
flow rate decreases as the supply voltage decreases.
Carefully act on the screw in the middle of the head to manually release
the crankshaft; circulation starts up immediately after the rotor is
released and the LED switches from red to green after about 10 seconds.
Check that there is no fault on the pump (on its wiring or electronics).
