Since descaling my Mini Vivaldi ii S1, as soon as the brew boiler is at temperature, the electrics in the house trip. It was working for +/- 1 week after descale perfectly before developing this fault...I have replaced the boiler/element and have also taken the wires off of the element legs to try to eliminate but the problem persists...I just can't seem to get to the bottom of it!!.... Any other ideas as to what the problem could be? I can pour espresso, the problem is when the steam boiler tries to engage....Thanks very much in advance.
