Oh yes… never buy a Miele oven with touch buttons
Two problems:
Buttons stopped working after warranty expired so had to pay for a service call to have it fixed. Luckily no parts were needed. I don't recall the reason right now.
It has a spinny disc, so like a potentiometer but not. It is a flat removable ring and behind it it uses a touch button of sorts
You have to pull it off amd clean it before every use for it to work and when it does work it is very fiddly to use.
I live with my 5 adult sons in a house with a small kitchen. Every hip-level surface gets smacked regularly.
