Vaillant Arotherm Plus or rather Vaillant Aro Horror plus nightmare

installation content: DHW cylinder, Hydraulic Station 97/6, MHT 150, VRC720, AI and VR71.

what a mistake to make, first day straight F.1100, then either runs DHW or heating but never together, happily passes all tests, even immersion test  but after restart gives me F.1100. who from vaillant come up with that stupid idea? why would immersion heater blow up , isn't it easier to put a fuse , clever engineering or playing ? On top of it, pressure goes up / down whenever it feels like. what a piece if metall-plastic waste.

i should never ever buy germany made again, their time is vorbei.
