Overflow all the time !!

Hi can anyone help, just having a issue with my heating system, bolier is a potterton promax he which is located in the kitchen , my tank is located in top floor bedroom, I believe it's restricted tank it think, tribune, as my last plumber could not touch it as he was not trained, its just had a service so was running OK, all of a sudden the over flow pipe is constant, its a large flow of water running straight out side, pressure cold is 1 bar, and it runs without having heating on, there are two small tank above it !
Anyone got any ideas

You have an unvented cyclinder (the two other 'tanks' are expansion vessels) and you need to contact an engineer with a G3 ticket.

Have a look at page 21 on the attached link http://www.elan-homes.co.uk/wp-content/uploads/2013/05/tribune-he-install-manual.pdf

Turn off the water supply and boiler until you can get the plumber back.

I have played around with both pressure relief valves and turned water back on and now it's all working again !!
I know the issue is not sorted so any ideas would be helpful !!

I will turn off then and call a plumber tomorrow, thanks guys

Chances are when it was serviced one of the safety valves didn't close properly, your playing with it has re-seated it.

You need to get the qualified guys back in, tell them the symptoms and they need to check the safety systems again.

It started again after ten minutes so have switched boiler off and cut supply to the tank .
Thanks for all the advice guys !!!☺
