Suspect one of the gas solenoids may be shot.

Hi
Thanks for your suggestions
It turned out that the changeover valve spindle was failing to activate the microswitches reliably.
A full turn of the adjuster screw breaks and makes contact every time now.
Thanks again
Great website

Thats just hiding the fault for a while.

A new diaphragm will be required as Mr Dole pointed out.

This is now a very old boiler and you should be starting to save up for a replacement.

Changing the diaphragm may be an interesting job.

Why?

ChrisR · 21 Jul 2006

The diverter valve looks fairly normal, plastic box sitting on top with microswitches inside. Box held to brasss casting by a metal spring clip. So to inspect, you can just pull out the clip, and take the switches off, yes ?

Yes you can, but when the water hits the ceiling you realise you shouldn't have...

Funnily enough , a mate told me in the boozer last night that he did just that. (customer stood behind him shaking his head in disgust)

Its good when its someone else, don't you agree?

Why is that then?

Thanks for your additional comments guys.
I changed the diverter valve (including the diaphragm) about a year ago so I hope it`s going to be OK.
Fingers crossed!

Yes, I`m saving up for a new boiler because it`s old and the price of gas

Agile · 27 Jul 2006

Perhaps it was just not set correctly a year ago then!

Save up quickly! With the price of gas not many people are going to be able to afford to operate non condensing boilers.
