Hello, I bought a karcher HDS 895 from 1995 and it worried me that using only cold water in the window on the boiler you can see a jumping spark. Therefore, my question is whether the transformer should give a spark all the time or only when switching the switch to 2 stage (hot water)
Maybe someone tells me exactly where the transformer should be connected, maybe you connected it wrong?
