I was descaling my office control machine this afternoon, anyway it was all going to plan but while rinsing and making sure my wife and I would be able to enjoy a morning brew disaster hit. I pushed the button to run some water through the group head it sounded like the pump was struggling like when it's back-flushed however unlike that there was magic smoke followed by an orange flash before I could unplug it.
I've taken the top off for a look I can't see anything obvious
I'm pretty handy and have figured the vibration pump is toast and that's probably something I can handle myself once I get one but before I do has anyone had something like this happen before and is there any chance it's something else that blew up?
Thanks in advance
