He was from Heat Team and the problem appears to have flummoxed all who have looked at it which is a bit of a worry. The noise literally just came back on for 3 secs and went off. I'm wondering if I need to call them and insist on most experienced engineer as it's not cost effective for them...

Thanks very much for your earlier comments - they make sense and I would like to think the next engineer would check the things you've said automatically, but if not, I will certainly ask him to. Best, Hazel

Forgot to add that the boiler is in a first floor bathroom against next door's party wall and is in it's own purpose built cabinet. It almost sounds like a fan/buzzing noise and after 2 hours has just gone off but no doubt it will start up during the night.

Have underfloor heating downstairs and rad heating and hot water...

Sorry to sound like a complete incompetnt but I'm not technical - it was the 3 small box type structures that sit below the Honeywell Timer that he replaced - and I'm now unsure if they are just called motor switches - or are they known as the 3-way valve? Apologies for being confusing.

Hi Dave, He did, yes.

Hi Everyone, I recently posted a message as my Potterton Suprima 80L was turning on and off day and night intermittently whether or not the timer was on or off. Was keeping us awake with fan being activated and turned off and other odd random noises. Had new PCB changed as have call-out...

Don't think he does. Just interesting that you had suggested what it actually turned out to be and how useful information sharing can be. Thanks again.

I mentioned it but it was a different engineer and he was much more clued up than the others. He agreed the forum is very helpful.

Engineer arrived today and boiler happened to do what it's been doing while he was here. Investigations showed it was a faulty valve on the 3 way valve system. He repaired it and all is silent - keeping my fingers crossed it stays that way. Thanks for all your good advice guys - it was very...

Thanks Tony - I will mention these things to Engineer No. 3 tomorrow - really appreciate you taking the time.

Hi Tony, Am in Ealing, West London. In first posting, I did say where boiler was fitted - in a first floor bathroom in specially designed shelf cabinet - back of it is on party wall to next door - the side is by external wall and vent leads directly out. Hope that helps? Thanks .....

Dave, Thanks for v quick reply. Engineers looked briefly at valve but not sure how thoroughly they checked. I can mention that tomorrow. Don't know if I have frost stat - no bypass(?) fitted - will ask engineer to check. We moved in 2 years ago and house was totally renovated 5 years...

Hi there, This is my first posting - apologies if a similar problem to this has been posted but I've had a good look and couldn't find one. It seems to have confused 2 different engineers too ...... I am at my wit's end with our Boiler - Potterton Suprima 80 L - Honeywell Timer. About 3...
