Technology Connections' videos are a bit long for my taste. This one and its follow up really only have a few takeaways:
Dirt sensors might mean that deliberately leaving crud on the dishes (rather than rinsing first in the sink) leads to longer and better washes
Run your kitchen sink hot water a little before starting to get warmer water into the dishwasher
The first cycle is just water, before the detergent tray pops open, so put detergent into the pre-wash tray or just straight into the tub to make it do more cleaning in that cycle
But don't put two pods in, i.e. one in the detergent tray, and another detergent pod into the tub because these pods are very concentrated and harsh and will damage plates. Only add a little extra powder
