Just another thought. The flow through the boiler is much greater when using the bath as all other taps have flow restrictors on them. But having said that, you still get the noise even if you turn the tap down low as well.

That was my initial thought, but if you're in the bathroom the tap itself doesn't appear to be noisy. We have pretty hard water here and all the taps have ceramic valves and a couple of them can emit a high pitch 'squeal' depending on how open they are, but ironically not the bath tap. I guess...

Pressure looks fine - doesn't change much over time just the occasional top up every few months. No air trapped in the heating system. It's not the same sort of noise that you get when there is air gurgling around the system and only occurs when bath hot tap is on. Strangely doesn't seem to...

Our Potterton Promax Combi has started to become very noisy when drawing hot water for a bath. When any other tap is used you can't hear any noise of water going through the pipes, but when drawing hot water for a bath there's a high pitched whooshing sound. Almost like you sometimes get from a...

Hopefully you've figured this out by now, but the DID is the code you need to enter to get access to your camera. Depending what system you have, it is either on the camera itself or on the back of the display screen. You may also need the security code for which the default is usually 123456...

OK - here's an update with some additional info. It happened again this morning, but this time also when drawing hot water from a tap rather than just with the shower. Thus ruling out the shower as being the problem. I have posted a couple of videos to show what's going on. If you turn up...

Sorry - I'll try explain again. The problem has only happened when running the shower. After a few minutes the water has run cold, but if the shower is left running and the hot water tap is then turned on to increase flow rate, the boiler still won't fire. Admittedly it looks like a shower...

Flow rate seems fine. As I mentioned in the original post, increasing the flow rate through the boiler by turning on the kitchen hot water tap makes no difference.

No suggestions? Installation engineer just as bemused. Did it again this morning, have the manufacturers engineer coming out next week. Any bets on what he might find?

Any ideas about what may be causing this: Shower type: Bristan Aristan thermostatic bar. Boiler type: Potterton Promax Combi Both less than 18 months old. Ongoing intermittant fault since Christmas (has occurred 4x) Seems to happen on particularly cold mornings Thermostatic shower...

Thanks for your suggestion, I'll have a look when I get home. As an alternative, is this what would happen if the diverter valve was stuck open after a demand for DHW? Should be able to tell if it is sticking open, by looking at the position of the pin that activates the microswitch the...

I have a strange problem with our Halstead Ace High combi in that every now and then the CH switches itself on. Even if the dial is set to just DHW hot water is being continually being sent to the rad.s which get very hot. While this is happening the hot water LED (but not the CH LED) on the...

Yes - I think you're completely correct there, 'bodge it' describes it perfectly; the rubber collar is not angled as it should be. So long as the roof doesn't leak I'll have to live with it - I really don't want them back again to bodge it even further and risk them loosening slates. Still...

Well for what it's worth they've finished and disappeared into the sunset. Didn't even bother to knock to let me know they were done. The repointing job looks OK - I guess only time will tell. As for the chimney - you decide :cry: Pathetic - but what do you expect from a bloke with...

Well the Lone Ranger has turned up with a couple of 'his lads' - obviously has decided not to get the original contractors to sort this out so they're up there at the moment - hopefully repointing the ridges (subject of another thread). If you can picture one of those episodes from Rogue Traders...
