Is the electrode and lead in good condition?

they are any ideas were id get the user manual

Don't think it's a user manual you want so much as a service. Get a RGI in, it's not a DIY job.

if you go on the wb website you can download discontinued boiler paperwork/instructions

Agree with all the above! To check the flame rectification probe etc you have to remove combustion cover, unfortuneately not a job that is safe for you to do!

had a 15/19 cbi.just a bigger output but same problem.
1.pcb.
2.water leaking from right side made insulation soggy and fall on sparkers or sensor for flame.
3.air flow device tube blocked partilly.
4.has it gone off with a louder bang before stopped working.
5.ensure gas tap at meter is fully on.

really a job for a registered engineer or the makers espically if leaking water .

good luck.
