Hi all
Just wondering if this is anything to worry about. Worcester 24Ri, one year old. Intermittently the blue indicator light flashes (about once every second). The fault lasts about 2 minutes and is seen to occur maybe once a week (but then I'm not around to see it that much). It's as though the system reaches a state that the boiler doesn't like (maybe a flow issue when hw changes to ch - guessing) and it takes a short while to stabilise. When is occurred this morning I noticed some clicking, but it was not clear whether this was an attempted boiler operation or just expansion noise.
Any suggestions/recommendations appreciated
TIA
Phil
