theres no fault codes come up either , forgot to mention that.as i said it seams to make a strange whooshing sound as thought its trying to go through the cycle but just gives up !

Hi Thanks for the replies jajodu, Yep the boiler does start up and sometimes it you can her the valve opening in increments till its on full flame then starts making a whooshing sound and cuts out the cycle and starts again with slight temperature rise on each occasion but never reaching the set...

Hi ECotecplus637 showing full flame on the info panel yet temperature is only on 29 degrees and radiators cool appreciate any info
