Ravenheat Rsf 820 20 User Manual Online
I've got a Ravenheat combi boiler which is now 10 years old. I've been told these aren't great boilers and I have had various problems with it over the years.
It was working fine this morning but something's gone wrong this afternoon. Ran a bath and water was only luke warm which is unusual. After I stopped the taps there was an almighty clunking/banging from within the boiler and then a huge hissing noise and the pilot light went out.
Tried putting the heating on and the same thing happened. When I re-lit it and just tried running the hot water, with no heating on, it fired up then the pilot light went out again, but no clunking or hissing.
Now the pilot light won't even stay lit. Obviously I'm going to have to get it looked at after the bank holiday but just wondered if any of you are plumbers and recognise this problem and know what it may be? Or is it time to invest in a new decent boiler?!
Thanks for any help!

- #2Firstly, you're right. Ravenheats are horrible boilers in my view, troublesome, unreliable and expensive to repair.
It sounds like your boiler overheated, first thing to do is check the pressure gauge on the front of your boiler, the needle should read 1-1.5 bar of pressure. If it is below that repressurise your system to said pressure. I assume you know how to do this yourself, if not let me know. - #3Mine played up couple months back (No noise mind you). The pilot light kept going out and I had no hot water. Thankfully I have a cover plan on it and mine is over 10 years old also. If its the same problem as mine, its sludge in the pipes which has built up and stopping the water flowing in the tank. That is if what I was told is true of course? Basically mine is on its last legs (so Ive been told). The plumber bent a pin that he said wasn't quite making the connection to the part that operates the ignition when the water is put on.
I'm opposite now very hot radiators and very hot water.
Send a pm to seacam, he is very helpful on here. - #4Thanks for replying. This was the first thing I did as it had dropped below 1. It is now just over 1.5 but still won't come on.
- #5Ok. To make sure we're both on the same hymnsheet, what model of Ravenheat is it?
When you're trying to relight the pilot do you view any flame through the peephole in the boiler? - #6The plumber bent a pin that he said wasn't quite making the connection to the part that operates the ignition when the water is put on.
Sounds like your plumber is lazy.
He needs to change the diaphragm not just bend the microswitch that it acts on. Eventually the diaphragm will wear away completely and no amount of microswitch bending can rectify that. - #7It's a Ravenheat RSF 820/20 T Fanned Combi.
Yes, the flame lights up when I press the button in but no matter how long I keep it held in for it goes out when I release.

What a D***head. I have a customer satisfaction survey to fill out for Legal And General Home Aplliance cover here. I am so glad I have not returned it yet. Everybody seems hell bent of just ripping them out these days. One thing really really hard to get is an honest reliable plumber (sorry gas safe). Thank goodness for our digital spy friends.:) - #9It's a Ravenheat RSF 820/20 T Fanned Combi.

How long ago did it cut out? If it was earlier today chances are the boiler should've cooled sufficiently to let it be relit, if it still cannot be relit in this case you will probably have a secondary fault. The thermocouple/gasvalve or the overheat stat may have gone. It's not unsual for boilers that have permanent pilots to operate fine for months and when the engineer comes for the annual service the pilot refuses to relight after he has stripped it. In your case the boiler has overheated (for a reason which may require a more indepth look as it might not be solely because the pressure was low) and as the overheat stat is linked to the pilot, it shuts off the pilot as a safety mechanism. Usually it is tracable to the thermocouple but could be either of the above also. - #10Thank you very much for your help. The problems started about 4.00pm today and it still won't light now.
Thanks again for taking the time to help. Will try and get it looked at asap - I can cope with no heating at this time of year..but not with washing my hair in cold water!! :eek: - #11

Adding to Andy advise and it could be a combination of those faults, I want you to do something else, with out risking limbs.
Top right hand corner of combi front casing,---give it a thump, like you have seen in a comedy, whacking a TV, don't dent the case but 1 x firm thump.
Now if pilot stays alight and boiler fires suspect APS = Air Pressure Switchthis will need replacing.
Ravenheat boiler/combi develop a fault where the pilot flame, the size of it is to weak/small to heat the thermocouple, this of course will prevent the combi from operating.
The pilot light reg' can be adjusted but sometime a new PL assembly is required.
The injectors can get clogged, a quick clean/poke with fine wire can resolve this.
Ten years out of a Ravenheat, I've skipped them after 4 so you are not doing bad at all.
I'm wondering if you are on a pre-paid gas meter and you go on to the emergency a lot?
