Troubleshooting
Table of the alarms
Note: During overheating ERROR the burner stays ON to
cool down the boiler
In any situation of alarm or blocking the machine understand the cause referring to the following tables. Solve the
problem before resuming normal operation.
I n case of block of the machine the alarm lamp always remains ON, while
the numbered lights are to be blinking (1sec ON, 1sec OFF) depending on the
type of alarm activated.
Operations that must be done by assistance technicians
ERROR
MEANING REPAIR
1 Error caused by inconsistency signals
from sensors (S1 =OFF, S2=ON)
-Check/clean boiler water sensors
-Check boiler sensors connections
-Verify electronic ground at the feet of the water tank
-Check/clean water level chamber
-Verify water quality
2 Flame failure error – The phocell
doesn’t detect flame within 7 second
from diesel solenoid valve opening.
- Check/clean diesel filter
-Check if burnerfan runs/ignition transformer
-Check/clean/ set ignition electrodes
- Clean/replace diesel nozzle
-Verity diesel quality
-Verify/set diesel pressure
3 Boiler water shortage – Sensor S2
doesn’t detect water within 120sec
from pump starting
- Check/clean boiler water sensors
- Verify electronic ground at the feet of the water tank
-Clean water filters
-Verify water pump flow-rate (set pressure)
-Verify water qality
4 Water tank failure- The water tank
sensor S3 doesn’t detect water within
120sec from level shortage
-Check water mains connection
-Verify if water is present inside thetank
-Check/clean water tank sensor
- Verify electronic ground at the feet of the water tank
5 Overheating coming from opening
signal of TS1 automatic safety
thermostat
/TS2 manual safety
thermostat.
-Verify correct working pressure (pressure switch)
-Boiler dirty with soot
-Heat exchanger with limescale/clean
1+2 Overvoltage from power supply (the
PCB works within 41vdc) -Verify power supply voltage
1+3 Water pump error – The water pump
works more than 4 min.
-Check/clean water filter
- Check/clean boiler water sensors
-Check water pump suction hoses/water ilter
-Verify water pump flow rate/set pressure
