My Heating on my old potterton 80 combi is not coming on, I recently fitted a siemens rdj10rf to it and has been working fine for four weeks then today it was calling at the stat and receiving the signal at the receiver but boiler was not firing although there was a slight click when calling, hw is coming on fine so I ruled out firing issue, also checked connections and all were home, refitted system loop l to swl on boiler and boiler fires up straight away, I'm confused .com
Any ideas would be appreciated
