Fitted a HE recently on existing system. The system was power flushed prior to installation. Took temperature readings from flow and return and it was normal when system was operating properly.
Of late, once it has ran for an hour or so, it will shut down and relit for a few seconds, than ignition light will flash red for a sec and try and relight. It will continue to do this.No real fault code appears for any length of time. I happened to be there when this was happening and took temperature readings from flow and return. They were the same or the return was a degree hotter than flow. I have checked pump and it is working.
The pump is on the return directly above boiler. Polarity is correct and flow swirth is working correctly. System is zoned and has a by pass.
Was with boiler for four hours checking over system and no fault was showing in that time, it has however started acting up again.
I firmly believe that the fault is not on the boiler but on a system component. No matter what speed the pump is on , it could happen.
My first thought is to change pump. What do ye think, please?
