Baxi 105 - leak on the C/H diverter side

[astirl]

hi all

Thanks to all the great advice here I have in the past fixed the infamous dripping dhw side.
However, got the same drip on the heating side. Pin pushes out and makes contact with ease, heating side fires up, but when it retracts it drips .

Is it the same process?. Isolate electrics, drain heating side. Remove micro switch, undo back nut on sensing tube and then the top 4 screws. Then replace diagprahm spindle and the top nut with the internal o ring and washer.

I know it's old but it's worked great. Having an extension in the spring so it will be replaced but if this fix keeps it going until then over winter then I'm happy

Thanks

I have the service kit. Just making sure this is the correct way
