Here's a general boiler sequence HOT WATER DEMAND 1. Demand for DHW 2. Domestic hot water flow switch operates (continuity) 3. Control PCB sends 240Vac to the pump and the pump runs. *** If the pump fails no fault condition is displayed, but boiler will still operate 4. The C'HTG (primary)...

Does the boiler spark? You'll notice small clicking sound?

So just an update ive manged to fix the boiler and its now giving me hot water. So special thanks to DP and AGAS. Saved myself £££££££ from these rip off gas engineer's. Everyone should do bit of research and have a go themselves.

What to tell what the boiler sequence is. Had a gas engineers look at it. Most of them are useless. They dont know themselves how it works

Can someone tell me the sequence of operation is for ravenheat rsf 82e boiler so i can get a better understandings. Could the aps failed making the fan run fast and slow and not letting the burner kick in?

Yes,he did say he had only the central bit of the test to do. He did say there was a bit of water on the connector on the ignition board when he removed it so could be why it kept blowing the fuse on the main pcb until the water moved away but now the fuse doesnt low and fan just kicks in...

Why do i do your head in? If you don't want to respond anything productive to my post then why bother at all? It a forum for help and advice. I pay to get a gas certificate only to have a call to say boiler doesn't work now when its been fine just seems like a coincidence.

Are you sure the Gas safe engineer is is not called adam911? :ROFLMAO::ROFLMAO::ROFLMAO::ROFLMAO::ROFLMAO: Adm911 cant sign off gas certificate so wont be him.

If i messed with it i would have said as have done boiler work in the passed hench why i carried on this old post from 2 years ago as it looks like the same symptoms but only this time the the fuse was blowing at first and now its not but now the fan is going fast slow fast slow and burner not...

So do you think its the ignition pcb board at fault making the fan oscillate? All i wanted was a certificate but hes done summa to the boiler now.

I was looking at something like this https://www.victorianplumbing.co.uk/triton-t80si-pumped-9-5kw-electric-shower?campaign=googlebase&gclid=EAIaIQobChMIxuDemsLv2wIVmvhRCh0uVgttEAQYASABEgJRqvD_BwE&gclsrc=aw.ds The pump is integrated into shower. I think u just connect a header tank to the shower

Just been looking on screw fix website they sell electric pumped shower that are gravity fed so i think i could use a tank on it. Not sure though.

I get the low pressure light come on and the water goes cold untill tap is off. My parents have got same sort of shower and we could open 3 taps at the same time and dont get low pressure at all.

I could have my own new supply but would cost a lot more and would mean digging my drive up which i don't want to do.

Ok so thats not an option. Would buying a shower pump solve my problem? Not really sure what it does? My shower runs fine if no one opens a tap it just when the tap is opened im getting low pressure. What other options do i have apart from getting rid of the mains old lead pipe as that would...

I just wanted some advice. I have a triton 9kw electric shower thats fed from cold mains. I have a problem with low water pressure and flow. When the shower is running and someone opens a tap i get low pressure on the shower or even if next door opens their tap we get low pressure on our...

He is gas safe but i will get a gas safety certificate from another gas safe engineer that i normally use.

Thanks for that. I thought there might have been something in the glass to tell which way the glass goes in.

It was a baxi duotec 24 kwh. Outside is ok hes installed a 40mm drain pipe for the condesing pipe and sealed the brickwork around the flue.
