Several days ago, I found water on the floor by the boiler. I think it had come from the back flow preventer / not sure. I added water back to the system and I believe it re-ignited OK. I do not know if this is related to the problem I'm having.
Yesterday I noticed the boiler was off AND there were no LEDs on (neither red nor green). Would any limit/safety switch cause all of the LEDs to be off? Is there a fuse anywhere? Might the 24V transformer be bad? Any suggestions?
