Glowworm 24ci , no display on interface board

[Gareth Smith]

Its a little more involved than just replacing PCBs and by doing it your self its now cost you money, you have either damaged the board that you have fitted or fitted the wrong part, we don't only need experience with gas our trade covers more than what people think and it takes us meny years to gain our knowledge.

Do you mean your own diagnosis? Or a long distance guess without multi meter? (an essential when diagnosing electrotechnical faults)

Original diagnosis was by a heating engineer who consulted with glowworm

Who then provided a quote to fix ? and the OP decided to cut out the middleman?

I have a range of test equipment and have been working with electronics for a number of years so the electrical side I feel competent to test inspect and hopefully diagnose , haven't really got the time to search for and study wiring diagrams so I was hoping to get some help here, back to topic , the new PCBs are in and I have an error code of F12, first check on error code was loom between PCB and interface , checked and replaces loom between and still nothing , also used new loom to be avail , further searching in to f12 and it seems to be a bit of a can of worms

I decided to cut out the middle man , engineer knows me and knows i am more than competent to change a PCB as glowworm had diagnosed to be the fault , didn't want to take that route again as if glowworm couldn't correctly diagnose I thought you guys with your time on the job, hands on with the equipment would be better to ask for advice

And is your engineer friend coming back to test and make sure that the boiler is working safely ? its not just a case of replacing the boards other things to be tested afterwards
