51/5 faults...

[Gasescape]

Red lockout & 2 flashes ( gas valve circuit ) fault
Boiler has had 3 pcb's & sensors in the past 14 months ....
All of which have got the system up & running.....
Had similar fault 2 yrs ago & baxi's tech. Support told me to change
Gas vale & lead aswell as pcb & sensor.....
4 months later this boiler failed with the same fault & system was replaced with pro 28......
Now have this problem again... Voltages , polarities , & resistances have all been checked as per mi's & baxi's tech ....
Baxi advise that the gas valve me be drifting/ spiking ?!?!?!? When system running & taking out pcb & sensor......
Anyone able to shed any light on this fault ???????

Loosing the will to live with these electronic bbu's ....... Chucking pcb's & sensors as a quick fix isn't my style !!!!!
( by the way it wasn't me who replaced all the pcb's ) just got landed with the ongoing faults....

You have not described your involvement.

If a Gas Reg engineer then ask in the Combustion Chamber as we dont give advice on gas/combustion issues here.

If the owner then call an RGI !

A BG or Baxi fixed price could have been cheaper. And BG cover would have been much cheaper!

I have attended both repairs & yes I am a Registered Engineer...
The initial job I attended 2yrs ago was a social housing repair .....
The most recent job is for private landlord who has contacted me.....
As per my initial post I have attended both repairs & have been able to get the systems up & running by replacing the pcb & sensor....
I contacted baxi's 2yrs ago & they advised to replace all the parts mentioned after which the system failed 4months later & the boiler was replaced,,,
The most recent job I attended this week & as before the system will not reset from lockout unless the pcb & sensor are replaced ( I carry these parts as van stock )
I spoke to baxi again yesterday who can shed no light on this fault & advise a dual visit......
I have spoken to several repair engineers & others have seen similar issues with these electronic baxi's.....
I did advise the private landlord that a bg contract would probably be a better option but he wanted the boiler up & running .....
As I said before replacing a pcb & leaving isn't my style ..... Getting to the cause of the fault is what I'm looking for ....
Cheers....
