POSSIBLE TROUBLESHOOTING

In the event of problems the boiler-stove stops automatically and runs the shutdown process and the display shows text
regarding the motivation of the shutdown (see the various alarms below).
Never pull the plug during shutdown on account of malfunction.
To start the boiler-stove up again after a shutdown, let the shutdown procedure end (10 minutes marked by a beep) tand
then press the button ESC.
Do not turn the boiler-stove on again before checking the cause of the malfunction and CLEANING/ EMPTYING the
crucible.
INDICATION OF POSSIBLE CAUSES OF MALFUNCTION AND INDICATIONS AND REMEDIES (shown only on the
control panel on board the boiler-stove):
1) Signalling: AL 01 (take action if the water temperature sensor is out of order or disconnected).
Problem: Shuts down due to the water temperature sensor being broken or disconnected.
Actions: - Check connection of the sensor to the control board.
- Verify functionality by means of a cold test
2) Signalling: AL 02 Failure of fume expulsion motor (this trips if the smoke extraction speed sensor detects a fault)
Problem: Shutdown for smoke extraction speed fault detection
Actions: • Check smoke extractor function (devolution sensor connection) and board (DEALER).
• Check smoke channel for dirt
• Verify the electrical system and earthing system.
• Check eletronic circuit board (DEALER).
3) Signalling: SF (H3) Stop/Flame: (this trips if the thermocouple detects a smoke temperature lower than the value set,
which it interprets as the absence of fl ames)
Problem: Turns off due to drop in smoke temperature
Flame may fail for any of the following reasons:
Actions: - lack of pellets
- too many pellets have suffocated the fl ame, check pellet quality (DEALER)
• Check whether the maximum thermostat has caused the problem (rare circumstance since this would
correspond to over heated fumes (technical assistance centre)
• Check whether the pressure switch has cut off electricity to the gear motor because of a blocked fl ue or other
problem.
4) Signalling: AF (H4) Failed ignition (intervenes if a fl ame fails to appear within a maximum of 15 minutes, or if
ignition temperature is not reached).
Problem: Turns off due to incorrect smoke temperature during ignition
Distinguish either of the following cases:
Flame does NOT appear
Actions: Check: - combustion chamber position and cleanliness;
- arrival of combustion air in the combustion chamber;
- if the heating element is working (DEALER);
- room temperature (if lower than 3°C use a fi relighter) and damp.
- Try to light with a fi relighter.
Flames appear, but AF appears on the display after Ar.
Actions: Check: (only by the Dealer)
- if the thermocouple is working (DEALER);
- start-up temperature setting in the parameters (DEALER).
5) Signalling: AL 05 black out stop (not a defect of the boiler-stove).
Problem: Turns off due to lack of electricity
Actions: • Check electricity connection and drops in voltage.
6) Signalling: AL 06 broken or disconnected thermocouple
Problem: Turns off due to thermo coupling failed or disconnected
Actions: • Check connection of thermo coupling to board: Check function in cold test (DEALER).
