I take your point, the issue is that some parts of a boiler are deemed

has no intention of it being repairable.

It's very odd. As you say most makers only supply new ones. No need to go
to the bother of fixing them if they can con you into paying for new.

My Viessmann PCB hasa several PCB fuses - the soldered in sort so not user
replaceable, unlike the main one. Yet they don't offer a repair service
for it. So why make it more expensive to manufacture than actually needed
- if it is a throw away part when faulty?

I entirely agree with your sentiment, hence why I wholeheartedly support
the likes of Geoff.

Not so long ago, circuit diagrams were published for TVs and video
recorders and the like.


My old (1976) Tandberg reel-to-reel came with a full circuit diagram. The design was very simple and easy to work on. I was told this was because the director of Tandberg back then (who had a fairly simple knowledge of electronics) would only allow the manufacture of things that he could personally understand and fix.
