I can confirm this, it took 45 seconds from stand-by today.
Another advantage of the machine is its internal structure, which makes cleaning very easy. You remove the brew group and two magnetic parts and have access to the interior, which has no 90° edges or corners. The surface is closed and with a simple wipe with a mop it is 99.9% clean - no comparison with the old one, which had edges, slots and screwed-on parts. The Siemens is really clean in less than 5 minutes.
