Code 14 (50-60-70-90): Overheating during flame
• The water inside the heat-exchanger exceeds of 221º F
The overheating sensor opens while the
flame is burning.
The causes are the same as in the Code 06, with the difference that the overheating sensor has a bad
contact and does not reads properly the temperature.
Code 09 (40-70-90):
• Solenoid valve circuit open (gas valves)
The circuit connector is loose
Insert correctly the
connector.
• Broken control panel
Change the control panel.
Code 12 (60-70-90): Error in the flame detection at start-up
• The control panel does not recieves flame detection during the safety ignition time before the burner
has lighted up (there was no flame before).
1. There is no sparkle between the electrodes in the burner
• Check if there is a brocken electrode.
• Check if the control panel is broken (you can hardly hear the sparkle inside the control panel)
Change the control panel.
2. No flame detection
There is flame but electrodes continue giving sparkles until the safety flame-
up time is exceeded.
• Check if the flame-sensor (ionisation-sensor) is broken and replace it.
• Check the cable from control panel to the flame-sensor.
• If the flame-sensor & cable are ok, replace the control panel.
3. Wrong Gas supply to the burner-becks.
• Lack of gas supply
Check the gas pressure at inlet regulator (20 mbar) with the boiler working
If
no pressure at all, check the gas valve if closed or the main gas supply.
• The solenoid valves are not opening
Check that solenoid conector at the control panel reads 12 V
DC
.
If not, change the control panel.
