This is the big cause of issues for us (Bosch 800). Either the arms are blocked or the holes clogged, or the middle rack's hose junction hasn't properly mated with the water source at the back of the machine.

Overall I'm really happy with this machine though; worth the pretty penny it costs.

Depends on the size of your household a bit. If it runs every second day, it should not be a problem. If you save dishes for a week or two, the additional water from the intensive program really helps to get rid of dried out dirt.

In that case it's called not a dishwasher, but a Cockroach Breeding System.

No, for that you have the rats eating the cockroaches.

Ours runs 2-3 times a day, but even still, I typically soak all the cutlery in a tall glass or pitcher full of water in the sink, and load it last minute. There are just too many nooks and crannies for stuff to get stuck in on a fork or knife, and they cleaning they get in a three-rack machine is too gentle for anything other than a sterilizing rinse.
