Suprima 80 boiler, diferent defect

[rocketfixer]

Hi there. I have read through the history of the lockout problems, and I have experienced all of these during 8 years of Potterton 80 ownership.
I have a new defect -
No light up of boiler. I have the upgraded (plastic box type) circuit board. I fitted a recon unit + have had this checked again... aparantly no defect with the Cboard.
The fan runs, the lights flash, the pump runs. There is no ignitor clicking, and I checked for 200dc at the gas valve but read zero. Is there a logical sequence, ie, gas vlv will not open if cb does not detect ignition... or visaversa?? please help. many thanks

You have apparently fitted the new PCB yourself which involves opening the combustion chamber.

You are also happy to do any work on your boiler yourself when you are not gas safe registered.

Since the fault seems to be combustion or safety device related then I will not be able to give you advice to enable you to proceed with the repair. Whilst you are probably reasonably competent to do simple work on your boiler there are many nupties who read these forums who are not.

I am also concerned that you buy "repaired" boiler parts. Quite apart from safety aspects, my experiences of those is that they are NOT always properly repaired and some colleagues have found some which have had safety circuits disabled.

Us registered enginers are not permitted to fit repaired parts because they are not approved by the manufacturer.

Hi thanks for the quick reply 'agile', and comments, but not helpful to progress problem.
The nature of forums dictate that only a brief out line of the history is possible and details of the when, who and how is not normally required.

Although this is a forum, you have taken my vocabulary quite literally. We all know not to work on boilers. I pay a vast amounts of money to Registered engineers, who seem to work their way through parts (normally start with the c/board) until its fixed.
Most guys on the forum have seen the reoccurring defects, and I had hoped to gain some advice to pass on, as the engineers are so busy.
I hear what you are saying about reconn parts, but components from a recognized and well respected supplier ok. Bearing in mind Pottertons reputation/ reliability on new parts very suspect and worrying.
Any help full input much appreciated.

Oh dear.......OP.....buy a new board. Your recon is er in need of reconing....the clue is in the word......con.

Agile, it is possible to replace just the board without opening combustion chamber. My guess tho is this OP would do anything to sort it without calling an RGI.....leave him to it.

If you cut the wires and used choc blocks to join the old and new wires then it would be technically possible without opening the combuustion chamber but no one in their right mind would ever want to do that.

"""I hear what you are saying about reconn parts, but components from a recognized and well respected supplier ok"""

Who is this supplier?

Sorry Agile but the new boards all have molex connections apart from earth and ignition, you pull em off and replace old board and recconect, only if it's an old style board do you replace the harnesses and need to access the combustion chamber

 

[rocketfixer]

Oh dear. As often happens on these great websites/forums, someone hijacks the thread, and a simple request becomes hardwork. My replies do not appear to have been read ..... regarding who is working on the system -RGI.
The Suprima range was one of the largest selling units and most RGI know them inside out.... including that the second generation cb uses molex connectors on a modified harness - 'Agile'... I'm disappointed.
No need to offer any more tech info.
I guess you did your best, thanks anyway.

I dont know why you are disappointed with me!

I suspect that you are annoyed because I dont support you using recon PCBs.

The new types are very much more reliable than old ones and a householder would be very unlucky to experience his failing.

Of course a professional will encounter a few but nowhere near the number of old ones.

I answer any technical questions but you have not told us who this recon PCB came from or really anything about what you are up to!

what light is it showing when its sat doing nothing?

 

[rocketfixer]

Hi nickso, thanks for your interest to help.

We have got the system up and running now. My gas guy was able to find out the start sequence ( my original question before the jobsworths hijacked the post!) and he discovered an intermittent fault with the airflow/vacum switch.... hard to detect because it was intermitent.

This is a great Forum... shame about some of the experts though!
Cheers again.

OP......this was never an issue you would have solved so all you did was waste your time and ours. If you had just called your rgi in he would (and did) resolve your problem

 

[rocketfixer]

You still are not getting it or reading the words . The RGI has worked the fault from the start,, (you desided otherwize).
He struggled because it was not a continous fault and did not want to throw parts at it. This wesite has a wealth of experience.
Please read back over all this listing to acess your performance and perhaps inprove future service.

Why do you bother contributing to a forum, if you arent prepared to read it, but, worse make up your own story to fit your preconseptions.
All that was asked was the start seqence, ie fan, air press swt, gas, ign etc etc. You clearly do not understand.

I think you have inadvertently discredited yourself... Im sure you are ok.
I will not return to this, but I'm sure you will reply anyway.... ego.

Your right i will return the post but ego has nothing to do with it...

No read what you posted....

I have the upgraded (plastic box type) circuit board. I fitted a recon unit

Quite clearly you stated you fitted a recon board.

Why do you bother contributing to a forum, if you arent prepared to read it, but, worse make up your own story to fit your preconseptions.

I did read it that's why we responded as we did. Oh sorry....must have been my ego triping over your stupidity.
