About water tank cleaning

#1: Post by **9coffee** » June 11th, 2022, 8:55 am

When I don't use a commercial espresso machine for a while, should I drain the tank?
Or should I sometimes change the water?
I care about hygienic issues.
Please advise me.

Plumbed in with no chlorine or chloramine reduction? It's hard to see how the brew boiler is greatly different than your supply plumbing. The brew boiler isn't generally open to the environment (vacuum breaker on the steam boiler though).

Even with a filter, the boiler is getting to close to boiling for a comparatively long time.

If it is a pour-over machine, I'd clean that reservoir regularly even with constant use.

Flushing the steam boiler to keep mineral concentration down is a good idea no matter what. One technique is to periodically draw off some water from the hot-water wand, assuming it is connected to the steam boiler.

Sounds like a great idea. Thanks Jeff!

Thank you Jeff,
Sorry, My English is poor.
The machine is Marzocco FB80.
I use a everpure for a filter.
I will change the water and flush the steam boiler.
That's kind of you.
