New Siemens Dishwasher iQ700 - curious about what a noise is

[RinseAndRepeat]

I bought a Siemens iQ 700 dishwasher recently, free standing model, and it's a very nice machine. No complaints at all. Washing flawlessly and the 'Zeolith Drying' works far better than I was expecting it to.

The blue lights are a bit sci-fi but, they're an interesting aesthetic.

I just have one technical question that someone who's perhaps a bit more familiar with these more recent BSH machines might be able to answer:

If you open the dishwasher after it's started, like say even 5 or 6 mins into the wash there's a sound which is like a fan or a vague hiss that keeps running while the door's open. It's not very loud, just like a vague sound of something blowing air. It's definitely not a fault, but I was just wondering what component / system would be making that sound?

My boss 800 does the same thing and I don't know why but I really just figured it was part of normal operation so if anyone can enlighten us with what that noise is and what it's for we'd appreciate it

I was wondering if it's something to do with the zeolite system or something.

Perhaps reading the Owner's Manual might give you a clue.
