Alarm Code PROBLEM SOLUTION
The blower fan is working but there is no
ignition spark or no flame in the burner.
1. Check if the Burner control board is correctly supplied
2. Check connection wires between Burner control and Blower
control board.
3. Check Orange light on pins 11-12.
4. Check fuse link on Burner control board.
5. Check the insulation of ionization measure plug and its wire.
6. Check ground on pin 16 of Burner control board.
7. Check continuity of high voltage HF cable ( max 1,5 k-Ohm )
on the igniter and on the spark plug.
8. Check the spark plug ground connection
9. Check diagnostics on Burner Control board.
10. Dismantle the spark plug and check the electrodes.
The blower fan is working but the spark
spread out of the burner
1. Check continuity of high voltage HF cable ( max 1,5 k-Ohm )
on the igniter and on the spark plug.
2. Check the spark plug ground connection.
3. Check ground on pin 16 of Burner control board.
4. Dismantle the spark plug and check the electrodes.
The blower fan is working and the spark
is good but there is no flame ignition.
1. Check the inlet gas pressure.
2. Check gas valve power supply
3. Check gas nozzle
5. Increase gas pressure regulation (PR.ADJ.) until the burner
ignition. (see section 4.3.1.)
6. Check gas pipe fixing
7. Check that the outlet pressure of the gas is free
8. Clean the blower fan air intake
9. Check outputs of heat exchanger on the top of the oven
Detonation at the ignition
1. Dismantle and check the spark plug.
2. Check combustion and gas parameters.

The flame is lighting but after some
seconds the flame goes off.
1. verify the flame detector cable
2. verify the correct power connection (see chapter 4.2.3)
3. check the small led on the burner control board for status
informations and/or diagnostic mode.
4. measure the ionization current.
