I'll chime in and say that, unfortunately, once you land on a good combo of detergent for your water conditions, sometimes the detergent brand will "reformulate."
You'll then get weird results you're not used to.
I've had this happen in the past.
Procter & Gamble is NOTORIOUS for constantly futzing with their formulas.
Sometimes I have good luck with Cascade pods. Sometimes not.
Cascade powder is pretty consistent, but it doesn't work well in all water conditions.
I've had better luck with Finish products in the past, which are more affordable too. But they also like to change things up once in a while.
Finish powder WAS working best in my 90s era KitchenAids, especially with coffee stains.
But my local stores have all stopped carrying Finish powder :/
Even when I've moved addresses, the differences in water source chemistry often forces me to re-calibrate what detergent to use, and what machine I have.
It's a fun game.
This of course is always dependent on wether your flavor of machine is functioning properly. And from what era.
Older machines tend to not like the pods. Newer machines are programmed to work best with pods.
But SOME older machines can work with pods, but not all brands.
