To be fair I've had a good run and very few problems, and the big thing is none have been complete 'show-stoppers' - I've always been able to reset or wiggle something and get the boiler going, or, as in the most recent case, replace with the original board I still had.

Good luck with yours, but what put me off changing to the modified board is you still see reports of failures.

I also keep thinking I'll just dump the boiler, but replacing it won't be trivial as it'll need to go somewhere else.
