Thanks everybody. It was a jammed valve. Not sure if the motor also burnt out, but I'll save that for another day. You have all been fantastic, thank you.

Thanks again

I feel like I am getting closer, but your expert advice thanks. I removed the head body and I think the valve was stuck, it's moving about a 1/4 of a turn now. A question as always please, what activates the microswitch? I thought it was the gold lever but on manual there is a gap and it...

Thanks, you are correct. Even though I changed the motor in the other one :) :)

Thank you so much for your advice Madrab.

Hi, the latest. I fitted a new isolation (full bore) valve as the old one had failed. Don't know where the rubber seal has gone! I also fitted a guage to the pressure reducer. It shows approx. 3.75 BAR. I tried to adjust the valve but it showed no difference. Interestingly, there wasnt a...

It's a Deva. The old one wasn't any better.
