Warm Up With Empty Shot It's recommended that you allow a good 20 minutes to allow the machine to heat-up fully before you use it. That is too long! Instead, just pull an empty shot through the machine and this will heat up the portafilter, group head and the boiler. Awesome!
If You Want Easy, Use The Double Wall Filter If you want a more forgiving coffee extraction then use the double wall filters. These are pressurized filters that are much more forgiving when you don't have the grind settings exact for the coffee beans. It's not as good as the single wall filters but it's a good starting point if you want a great cup of coffee.
