• Undo the screw 5 to remove the baffl e and screw 6 to remove the electrodes.
Propercleaning of the nozzle is obtained by removing the fi lter and cleaning the
slots andspraying hole with petrol, rinsing it with fuel oil. When reassembling
everything, payattention to the correct positioning of the electrodes-baffl e.
Condensate tank
To access the condensate tank, open the lower cover (Fig. 35).

4.4 Troubleshooting

Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler
fault, the display will fl ash together with the fault symbol (9 - fi g.1) indicating the
faultcode.
There are faults the cause permanent shutdowns (marked with the letter "A"): to
restoreoperation, just press the RESET button (3 - fi g.1) for 1 second or use the RE-
SET on the remote timer control (optional) if installed; if the boiler does not restart, it
is necessary to eliminate the fault indicated in the operation LEDs.
Other faults cause temporary shutdowns (marked with the letter "F") which are
automatically reset as soon as the value returns within the boiler's normal working
range.
Circulating pump diagnostics
Some faults linked to the circulating pump are signalled by the LED located around
thespeed selector (fi g.38).
