Hi there,
long time lurker first time poster. I have an external grant boiler with a reillo rdb burner.
My tank ran dry last week got it topped up yesterday and so my trouble began.
I bled the burner as I normally would. Heating fired no problem went back into house and realised the heating was not on...back out to boiler. I noticed when moving the wiring junction box that it sparked the burner into life and it fired for a minute or two and then knocked off. When I got back into house I noticed the heating controls had gone and the fuse had blown. I replaced the fuse and it blew again immediately.
I isolated the pump checked the motorised valves all with same result. When I isolated the boiler limit stat I found that the fuse didn't blow, heating controls were back on but the reillo burner was dead....
All my electrical connections are sound and untouched by the elements.
Anyone have some suggestions as to what the issue is from info above? Does the burner need the high limit to receive its power?
oh I had a spare stat so I went ahead and replaced it but same issue occurs.
thanks in advance
