Suprima HE nightmare

[martinthefirst]

OK I could tell the whole story but this is where I am now . The boiler will work for a day or two and then lock out with ignition fault. Reset and it may go for another couple of days. Heating engineer could find no fault & said wait until it fails altogether. Thought I might as well change the PCB, got a refurbished one and it locked out immediately but with circulation fault! I surmised I had been sent a dodgy board, sent it back for a refund, bought a brand new one and this does the same, , circulation fault!! Arghh. Put back the old one and back to 2 days running then ignition fault. So.... must I presume the old PCB is knackered and is displaying the fault incorrectly & I really do have a circulation problem??

How old is the pump ?

About 10 years, It is on setting 1 of 3 I could turn it to 2 and see what happens?

 

[ShaunCorbs]

Yes turn it on 2

 

[martinthefirst]

Yes turn it on 2

OK, will do, I turned it down a few years ago as I was having to bleed the radiators and I think it was pulling in air, and it solved that problem. Maybe the pump is getting tired.
