It’s exactly what I would have done , does sound like board now , bloody expensive to try , are you using bell wire ?

Have you connected to 3 & 4 on x21 ?

 

[Gasmk1]

Yes 3 and 4 have done several before on the 100. at my last house I installed it on the 200 never a problem till this one. Boiler is about 5 or 6 years old I am leaning more towards the board being faulty

Long shot , still under warranty ?

no these only came with 5 year customer never had it serviced before now, no books all lost or misplaced when house renovated

Pffttt, if its board try fixed repair it maybe cheaper

 

[Gasmk1]

will just let customer know how much but it takes the savings out of the equation. take a lonhg time to recoup the costs. unless anyone has a freebie board they have removed )
