So I went to the Dollar Tree and bought a 708 gram box of dishwashing machine detergent for $1.25. It came to $1.36 with tax.
I watched a youtube video StashingAway here on the forum shared with me and the guy in the video said the cheap Great Value powder does a good job, so I figured maybe this even cheaper stuff does as well. In the video he uses 33g of detergent per load. Video:

So I just washed a load of dishes in our new Bosch Series 100 we bought earlier this month, with this Dollar Tree detergent. I measured 33g which is 2 lightly rounded soup spoons. (I poured the box of detergent into a Lock & Lock container and threw in a soup spoon as a measuring device for each load.)
The dishes came out clean and spot free. I'll alternate back and forth between it and the Finish and report back after a while.
The finish was costing us 19.4 cents per load with sales tax. This box of DT detergent contained 708 grams; at 33g per load it will give us 22 loads per box. $1.36 / 22 = 6.2 cents per load. 6.2/19.4 = 32% the cost of the Finish pods.
At 19.4 cents per load, one load per day, the Finish costs $71 per year. In contrast, the DT detergent is $23 per year; a savings of $71-23 = $48 per year.
I also bought a box of cascade powder from walmart and it's around 11 cents per load with tax; I'll try it out as well.. it's a lot cheaper than the pods but the DT is super cheap lol. (I would of got the GV powder he mentions in the video at 5.2 cents per oz but my Neighborhood Walmart didn't have any.. I'll have to keep an eye out for it.. will probably switch to that from the Dollar Tree detergent then.)
I'll look into the sensor thing more. I think a lot of the problems people have with the Bosch dishwashers is that they don't clean the filter perhaps? I am cleaning it once per month. Really easy to do.
