Hi, Just had an engineer round to fit a new PCB unit in my Ferrolli Optimax HE31 C combi boiler. Apparently once this is fitted you need to press a combination of buttons to get the boiler going...he didnt know what this was and arrived too late to phone Ferrolli
We have been without hot water for a couple of weeks now and I was hoping someone might know what this combination of buttons is?
Would be extremely grateful if anyone knows the answer.
Thanks
