Ha!
Thanks!

I believe the BZ02 has a vacuum breaker, so you should be able to put it on a timer with no problems.

Cleaning is pretty simple. Wipe off the dispersion screen and PF after every shot. Backflush and do a PF wiggle with hot water after every session. Backflush with detergent every week or two. Descale about once a year, unless you're using very soft water, in which case you may be able to forego descaling for longer periods.

Enjoy your new machine! You're going to love it. And if it's any consolation, you're getting a good deal compared to what many of us have spent on machines and grinders over the years.
