Interesting. Really, really interesting. One of the tips I got was
to run the water in the sink until it's hot, then start the
dishwasher.

I used a temperature probe and realized that if I don't do this, the
water only makes it up to about 125 degrees, WITH the heating cycle.
Only about 104 degrees without it.

I've run about 5 loads now, using this tip, and absolutely NO food
residue. And I was about to drop $1300 on a new Bosch!
