Boiler has no lights on, high pressure and is leaking Breakdown Bible wet edition and Partsarena

🔧 leaking boiler and no display 🔧
Customer called to say their boiler was dripping and there was no lights on the display…
On arrival I saw a Worcester Bosch 30si on the wall dripping from the back left, no lights on and the pressure was at 3.5 bar….
I managed to use the Breakdown Bible wet edition and Partsarena to assist me on this breakdown which definitely didn’t go straight forward…
