Last big purchase of 2018 - a new dishwasher

Air blowing

To my knowledge, only the TOL Thermador models have the Zeolite. What you hear is pressurized air being released through the vent in the water inlet.

Whoops, didn't see that youvwere from the UK. Never mind about the Thermador then. Still, the whistle sound is most likely air being released.

Siemens - sound

Hi H!

It’s more like a fan that is running in the tub somewhere - definite “blowing” sound

 

[logixx]

See... this is what I get for half-reading comments during my lunch break.

Okay, the sound you hear is with the door open. Yes, that can indeed be the Zeolite fan going. I once opened a higer-end Bosch with Zeolite during the prewash and was surprised to find the Zeolite fan continuing to run with the door open.

Thx

Hey Logixx!

Ha ha - no probs always appreciative of feedback. Ok that makes sense re: Zeolith Fan - just surprised
That it seems to run throughout the cycle !?

The Zeolith mineral is dried by a seperate heater in the Zeolith compartment during the cycle.
When how with which parameters I don't know, but it would make sense that it's running all the time with the Zeolith heater on during all the wash operations and then just turns off once drying.

I don't know if it runs the entire (washing) cycle. I don't think so. I know that the steam emitted from the drying of the mineral is to help heat the wash water - so it should switch off once the water heating cycle is over.
