I used to do appliance repair long long ago, more clothes washers than dish washers, but some.
With dish washers it was usually food gunk or grease preventing the water level float from moving freely, so not filling or overflowing :)
I am sure with newer models they have introduced more points of failure though ;)

We used to have customers looking at basic washers and deluxe washers side by side.
The would ask - What's the difference?
We would say - They're the same inside, but it's $100 per button on the panel.
