Yet another problem argh!

What is worrying me more and more is the fact that the problem could have numerous causes. I just don't now know who I can get to solve this, with 3 RGI's letting me down.
Do I now call a big company (Swale Heating is suppose to be good but work on the clock) BG (swore I wouldn't have them in the house again), someone else from the WB site? This is my main dilema.

Plumbing alone takes a while - gas is and always was a different ball game .As was servicing. A lot of those who know boilers assume they know pipework - sadly they don`t.

I am very sorry you have had such a problem.
Very unfortunately many people doing boiler work dont know everything that they should. the electrical aspects are the most common cause of problems.
But from a very early posting of yours:-
Pretty obviously the whole point of a power flush is to clean the water in the system.
After power flushing a system the water should be pretty clear.
A boiler I went to on saturday has such clean water that to demonstrate to the owner how good it was I even drunk a little! ( No, I am not suicidal in spite of some of the things I sometimes read on here. )
If the water is still black the call back the flusher and ask him what he has done wrong. Power flushing should cost about £300-£500 and take about 4-5 hours and use chemicals !

Phoned WB at 7.10 am this morning and had engineer arrive at 8.30 am - can't say they don't provide service
Anyway - at first he didn't think it was the boiler but there was no power between the boiler and pump valves etc. Said he would change the circuit board and it worked !!!!!!
One more problem to solve however, when he first took a gas pressure reading at the boiler it was only 15mbar. He took another 5 minutes later and it was 18.5mbar then again before he left and it was 17mbar. He says that I have a fluctuating gas pressure problem and called Transco out. He suggests that it is either a faulty governor or 'water in the main supply pipe'!
He has switched the gas off at the meter and I am now waiting for Transco to turn up. Was told that it would take about 2 hours so fingers crossed they come out today.
One day - I might have a fully functional gas central heating system
Thanks to everyone on this board for all the help and suggestions.

Oh dear, you have done and tried everything to get your boiler/system sorted and working. I actually feel quite sorry for you. It just seems that as soon as one issue is resolved another rears its ugly head. Chin up, keep smiling and don't bother doing the Lotto for a while, if you where lucky enough to win I expect you'd loose the ticket. The way your lucks going.
Spoke WB again and they got their engineer to phone me. I explained that if and when the boiler does eventually decide that it will fire, the water is circulating in the radiators fine, all radiators getting hot, so how could it be a pump problem.
He said that he would arrange for them to come out tomorrow and change the heat exchanger, could be it got mucky during the power flush. Apparently the HE also has all the sensors on it as well, so if that doesn't do it I am on my own.
Have arranged to get a new pump fitted tomorrow as well - so if none of that sorts it out I am at a complete and utter loss.

Just a thought, but if this is down to a flow problem, wanted to ask if the new automatic bypass valve could be responsible. It was put in at the same time as I had the power flush done and is set to number 3. I have noticed that, if and when the boiler has been running, and it switches off the temperature on the display increases. I thought the automatic bypass valve was to stop this.
So could the flashing bracket issue be down to the automatic bypass valve (clutching at straws here!)

You can adjust the by-pass to a lower setting, do you know which make it is?. I'm still very concerned that you have a 15/50 pump installed, do you know what size pipework has been used from the boiler to pump/valves?
Hi heatingman - make of bypass is not obvious - red with a black dial underneath with numbers I am getting a 15/60 pump installed on Thursday I think that with the new boiler a 15/50 isn't large enough for 22 radiators. Also getting an air vent fitted as I have been told that upping the size of pump could pull more air into the system. Size of pipework I am uncertain about but it is largish.
WB are coming back tomorrow to fit a new heat exchanger, they say the sensors are also on this. Then with a new pump if the problem isn't solved I am moving
Then of course I have the issue of the fluctuating gas pressure. Transco came out very quickly today and they fitted a new governor so I hope this has solved the problem, otherwise looks like it could be water in the mains gas pipes = good grief - how on earth does water get into mains gas pipes

open the bypass to number 1, I do belive the boiler is having trouble shifting the heat, it could still have a hard blockage somewhere.
When you switch it on observe the digital temp display, does it rise fairly rapidly. If its going up at 1 deg per second its too quick.
Was the guy that powerflushed the system called Richard Head, sometimes helped by his brother Nobby.
