potterton boiler pressure way too high - HELP!

[Steve100]

I've got a potterton boiler which has been no end of trouble! The pressure gadge is up to 4 and it cuts off probably for safety reasons. I have bled the radiators, and released the water from the flexible pipe attached to the two vavles.#


Just checked it again after all that and now the pressure is 1.4 then it goes to lock out.

What do you suggest I do?

call a gsr engineer,you may have a faulty filling loop,expansion vessel and a pressure relief valve

it has error number E 0.1
Looked up the manual and nothing there to help either, the pressure is back up to 3.5 then it cuts out.
