Can someone help.
I have an apollo 50 si boiler. the PCB and electrode lead have been changed twice over 6 months. The pilot is playing up again. It shuts off after about 5 minutes. When the PCB and electrode were changed in Feb 09 it has been working until now.
What could be the problem ?
Thanks to those who responded. What is an RGI and why is it that system was working until now.
