I had the same problem with my machine this morning. The 1 and 2 cup lights were solid green and the warning triangle was on. When I opened the machine to clean the infuser it was impossible to reach. I unplugged the machine and on switching this back on the infuser came down to its normal position. I have just cleaned it and turned the machine back on and it has just made me, finally, my morning coffee. Good luck
