When the milk is finally steamed on the dual element system, the machine is ready to continue making more espresso shots. Keep in mind that if you choose to get a single element machine, you’ll need to wait five minutes so that the boiler can cool off naturally and then run hot water through the steam wand for ten seconds in order to purge the boiler of steam.
There's one other area needing fixing, not only in these machines but in all super automatics I've ever tried - tiny puck sizes (diameter) = bad extraction. That's not me saying it. That's Dr. Illy and a wide range of scientific tests that the Illy labs have done finding the optimal puck size for superior extraction. At 46mm, these pucks are too tiny.
3) This machine is crazy smart. It knows exactly when to clean itself, or tells you when to start the cleaning cycle. To clean it, all you do is insert a tablet in the coffee powder drawer and it does its thing. It knows when it needs water, when the filter needs to be changed, etc. In fact, since we have a water filter built into our refrigerator, we just use that filtered water in the coffee machine and therefore we don't need to use the expensive water filters. Bottom line, if you just pay attention and clean the machine on a regular basis when it tells you to, this is a no-brainer machine.
