Hi
I wonder if can someone offer any solution... I have a Vaillant ecoMax 828/ 2E boiler which is leaking. To start the repair do I need to adjust the diverter valve to the middle position to purge the boiler? If so what function on the program do I need to go to adjust the diverter valve to the middle position?
