If he was that good, You wouldn't be on here looking for answers... Your plumber would have them ;0)

Go onto the OFTEC website and pick someone else for a fresh pair of eyes

Ok sat outside for a hour today watching what the boiler is doing.
After resetting the locked out boiler,the boiler fired and ran first time for 15 mins smoothly.

Then the boiler stops and takes 5-10 mins to refire,but now it is struggling to fire.
It fires,but immediatly stops,and continues to do this 3 or 4 times,
but then fires up again, and runs for 15 mins smoothly.

It repeats this exact sequence 7 or 8 times before finally going into lock-out..

That can mean almost anything. Control boxes, photocells & solenoids on all burners can cause intermittent trouble, but , as i have already said, check the oil pump. If it is 10 yr old, then it is very old for a Riello pump as they are mainly what goes on those burners. I often carry one in from my van with my tools, as nearly always the problem. No point you waiting till winter hits hard, get it sorted with someone who knows what they are doing.

I dont quite know what you are after all the problems that it could be have been, have already been mentioned, no one can categorically say it is anyone of those things without personally testing certain things. You cannot reliably diagnose a problem from sitting at a computer screen. There are some engineers that are extremely good and there are some that are good. I personally dont like to be beaten and I havent been yet, I would be very dissappointed if I could not get a burner going or at least reliably diagnose the fault after one or two visits if the problem is intermittent. I carry about £2000.00p of parts in my van so most parts can be tested on the same visit. Get another engineer around.

I am trying to add as much detail regarding the bloody problem a i can,i am not a engineer and the 3 previous so called engineers have also fkd it up,so you tell me who do i try next????This guy is oftec registered and fully recommended
I live in a rural area so engineers are not exactly abundant.
I am worried that my family are once again going to have no heating again,thats why i am sitting at a computer screen,trying to get information from experts to possibly help with a diagnosis.
You are talking like a average punter should know whats hes talking about..i know nothing about plumbing,i am i roofer trying to get some ideas of were to go next.

You 2 may be the dogs blx,but odviously other engineers are not,which may include the next so called expert that has a look.

Try the above link. They'll probably be more expensive than your local chappies but they only service Grant boilers and will have the backup of their manufacturers.

I hope I'm not one of those dogs balls ...

I am not trying to be funny, but how much money do you want to spend? Or how much money is the engineer going to charge you? I guess that is part of the problem & I don't blame you for not wanting to spend all you have. If you can afford it, you could have a brand new burner for less than some engineers would charge for repairs. But you will need it installed/commissioned. If I was a local, I would sort it no problem. If it was my burner i would repair it unless it was very old or in very bad condition.There are about 6 main parts to your burner, so it's not rocket science, you probably haven't a top boiler guy - oftec trained means nothing much, but experience is way ahead. I have just fixed another one of those burners today, - oil pump broken as usual. This time it was totally gone, so didn't have to think before renewing it. 5min job.

I am in north devon.As mentioned,the oil pump will be looked at next.

If dirt got into oil line then it would clog to some extent oil filter at pipe + oil filter in oil pump + fire valves & everything else. If it is a decent paper element filter ( at tank ) then hopefully it will only be dirty. The 50/70 euroflame is very likely not to start in cold weather if it hasn't been set properly. The CO2 should be set correctly. Make sure the bloke working on it knows what he is doing & uses test equipment. Also he has to be oftec qualified. Oil pumps & motor condensers are what gives trouble on RDB burners.

"Has to be oftec qualified" Certainly does not.
My uncle works maintenance for a local university. A fitter by trade.
He knows heating basics so similar knowledge as first or second year apprentice.
Anyway they sent him on an oftec course and he passed.
He could name the different components of the burner but absolutely no chance of
diagnosing simple lock out faults.
Obviously there's plenty of good guys oftec registered but also plenty of muppets.
This is why I havnt bothered because its extremely unlikely I'll learn anything.
I'll stick with the manufacturers courses for updates on building regulations and keep up to date with my G3.
know oftec though unless you guys know something I don't.

Certainly does. How are you going to get anything passed? What if an oil boiler you serviced developed an alleged dangerous problem, - no qualification, no proof you know anything. Tell a judge you haven't qualifications in oil, but know how to safely do oil work as you do other bits of plumbing just won't be accepted no doubt.
Anyone working on oil boilers has to be OFTEC qualified and registered, or other to prove competent. They will not be able to fill in paperwork without having oil qualifications.
Don't get me wrong, I do entirely agree with you that OFTEC is ridiculous and costly. Money for nothing, and I know oil is not regulated fully.
I have a friend who never worked at plumbing or oil boilers, but he did the OFTEC 101 servicing/commissioning and the 105 oil installation exams no problem.
