Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am APPLIANCE-HVAC GURU a very experienced tech on here and I try to get to as many customers as I can. I just picked up your question now.

Please allow time for me to respond, sometimes I get the questions or responses late so please be patient as I have no control over the site issues. NOTE, I have nothing to do with your payment to the site and did not receive that money.

Answer:

This is an ignition fault code. Meaning the unit has tried to light 3 times and failed. So you should check your gas supply, see if the boiler actually is trying to light up...if not often the PCB board is bad causing the issue. Lastly if it is trying to light but fails the ignition device may be bad on the unit causing the malfunction and will need to be changed.
