Thanks again for all your help. I can check the airvent is clear myself, and I can also check the dhw stat no probs. I recently flushed all the rads and then treated them with inhibitor so i dont thinki there is a problem there. I f I get know joy with tha suggestions then i will get a gas man...

you have to re format your sd card. i cant remeber if it is ntfs or fat32. just try both, it only takes a few seconds I did this on mine and it worked

I think we are on to something here. when i run the hot tap and the burner kicks in all is fine. leave it on for a min or so then close tap, the burner goes out as it should. I can hear a noise similar to air sucking in or blowing out until pressure is equalisied, similar to opening a fizzy...

Thanks for that. Just tried what you suggested, when the tap turns off, the combi shuts down straight away, within 1 second. The pilot light only goes out when it has been running for a full bath or a shower.

I have just quickly run the hot water and the ch and the pilot light stays lit when the bioler is fired up

Thanks for all the advice. Pressure is at 1.5 on the dial. Where will i find the themister? I will have a look at this, and if it does not fix the problem then I'll get a gas man to look at it. thanks

Thanks for the quick reply. Do you mean mains water pressure? The pump doesnt sound noisy The flue is clear, its second floor height. and I dont know about the gas pressure

I wonder could someone could possibly help? When I run the hot water for some time either for a shower or to fill a bath, once i shut the hot water tap and the boiler fires down, the pilot light goes out and will not light for about half an hour. It only does this if the hot tap is running...

it was a genuine part. strip it back down and clean? any ideas on the pilot light not relighting?

I replaced the diverter valve on my boiler earlier on this year, the diaphram was damaged. When my heating is off, but hot water for the taps is called for, it still heats the radiators. Anyone have any ideas? Also some times the pilot light will go out and will not relight at all, sometimes...

ok, just an update. removed diverter valve from boiler and stripped it to find that the diaphram( is that spelled correctly?) has perished and has a hole in it. ordered a new one from plumb centre and re fitted. problem now sorted and house nice and warm again. I removed the time clock...

thanks for the advice. just a couple of questions is the diverter valve, the 3 way valve as it is called in the manual? is it possible to do away with the timer and fit an aftermarket timer which will be more reliable than the ravenheat timer? thanks again

no power cuts or disruptions to power supply. just had a look, and the timer works fine, but it doesn't always act up until after a day or so. so it's hard to find an intermittant fault.

thanks for that speedy reply. i'll look at getting the diverter valve replaced. looking at the clock now as we speak. does it have a battery? just a thought

I have a Ravenheat RSF820/20 combi boiler fitted for the last 5 years. For the first 4, it has been faultless, but over the last year, there are one or two problems appearing. First of all, the timer seems to alter itself, changing the on off times and days of it's own accord...
