hello I was wondering if you might know whats going on with my brera machine. we have had the machine now for two years with no problems. but today when we turned on the machine it ran through its normal cycle. all the lights came on like normal. but when i pressed the espresso button all 4 of the upper warning lights came on and stay on but nothing happens. the only thing that I can do is power the machine off. I tried it a couple of times but always the same thing. any ideas. my wife loves the machine and is loosing her mind. any ideas?
