Duetto 1 sirai steam tank autofill leaking?

floydo

Haven’t found anything on this searching the web, but overnight the steam boiler overfills on the plumbed in (2bar regulated) Duetto. Suspect the
sirai valve is not completely sealing. This is flange mounted with a spring clip on top. Overfill after removing hot water from steam tank operates normally. Can I pull clip, disassemble and clean, remove and replace, or?

I thought there might be some knowledge on the process here :)

Suggestions?

Thanks

To overfill overnight, it would be leaking when plumbed in…this means a clean could well solve the problem of it not sealing completely. The clip and coil can be removed and the solenoid opened for cleaning, or simply buy a replacement from BB etc.. if that doesn’t work.

Cleaming it would be far easier of course, as removal is…cramped….and Izzo loved doing two things which really ticked me off:

Using permanent strength threadlocker
preassembling component groups and then fitting them, making removal difficult sometimes without removing an awful lot of things. A 10 minute job turning into a mountain of disassembly and hours of work.
