Potterton boiler Error code E 01 with lockout

Posted by Morgan Ayanbisi, on
Manual states primary pressure too high and I have released the pressure via the primary pressure release valve on the Potterton Powermax HE boiler. It also states to check, adjust or replace primary expansion vessel. Can this be done by us or a heating engineer?

Hi, You really need to get a heating engineer as you shouldn't be touching the boiler unless you're qualified and gave a valid gas safe registration!
