I would not use the type of flexible copper pipe fittings you have mentioned because they are not rigid and could fracture for several reasons. Also the type i think you are talking about would cause turbulance in the flow of water. To the RGI's, i am lost with what they class as competent ...

I have found a recon board on fleabay for £25.53 + postage. I am reluctant to buy it coz i am thinking that there is not really a lot that can go wrong with a relay and the only reason that it would be smoking is if it is overloaded caused by another component failure. money is an issue...

no i haven't, i will give them a try. hope that it is just the board. I have just bought this house and found the boiler is in need of some major attention. will probably end up buying another 1 when i have the money.

Where can i buy a new or recon p.c.b for a vokera 20/80 rs flowmatic ? The relay on the board has gone faulty and is smoking !! Not sure if this is caused by another part failing and putting extra load on the relay ?

Seems like its not only your baxi that suffers from this problem. Same problem occured with my boiler ( ariston microgenus 23 ) and i helped someone out in the thread below and it cured their problem too. Thanks for the info ! //www.diynot.com/forums/viewtopic.php?t=61538

can't believe the installation of this system, besides 'appearing' to be immediately dangerous because of the flueing/intake arrangement it is so unsightly it begs belief. At college my tutor said if you wouldn't have it in your own home then don't expect others to. That flue is extremely unsafe...

As i said i am not familiar with the boiler so i can't say how the boiler would react to flame failure! On hot water mode the boiler modultes the flame to give the correct heat required for the desired hot water temp.

Ok, you may have cured the flame sensing problem, but did this cure the " whistling " noise ? i don't think it would have been anything to do with this. As micky p says it sounds like the heat exchanger also requires cleaning out and the seals condition checking. Blocked heat exchanger would...

I wouldn't jump straight in and replace the pcb, have you looked for dry joints on the old board? Have you checked the electrodes are in good condition ie not dirty, corroded or broken and that they are also in the flame? the flame itself completes a circuit between the electrodes but we are...

i have a microgenus 23 mffi ( would not have another ). was having a similar problem you are having. after many strip downs i found that the electrodes were corroded and causing the flame rectification circuit to fail when the boiler flame size reduced due to the modulating action of the boiler...

what is your pressure gauge reading?

sounds like you have an air lock around the pump. Is it a combi boiler? Is the automatic air release valve open?

i would bridge the plastic just to protect against the fact that the bonding ( after the plastic section ) could be disconnected at a later date either for repairs to be carried out or by a person who doesn't know better. The water in the pipe is capable of conducting electricity and therefore...

seems to me like the first radiator is getting hot through gravity circulation and you still have a problem with the pumping of the water around the system ie voltage supply to the pump, blockage in the return pipe or an air lock in the system. just a few thoughts that you have probably already...

hello Chris, have you checked the pressure in the expansion vessel? is the automatic air release valve open? are you getting any drips from the pressure relief outlet ( blow off pipe )? Andy.
