I moved to a new condo 2 months ago. The condo came equipped with the Fisher Paykel dishdrawers. I use Cascade powder, and it does a good job. I just cleaned the filters yesterday, and I should have done it when I moved in. The previous owner obviously didn't clean them at all. They were filthy like you wouldn't believe.
Do I like them? Let's say I don't hate them, I will use them for now. I do miss my Bosch dishwasher from the previous house. Main reason is the small capacity of the dishdrawers. There is always one drawer full at the end of the day, and we are only two people in the house. And the way the racks are set up, you can only put large plates and small plates on one side. The other side is mainly for glasses and cups, and you can't fit too many of those. 2 rows of 4 or 5 glasses, depending how big your glasses are.
One good thing is the fast cycle. If you use Fast cycle, and eco option, you get a full wash, and a full rinse in about 25 minutes.
Am I saving energy by running a half dishwasher daily, compared to a full dishwasher every two or three days? I don't know.
One good thing, if you have a drawer running, you can still put in dirty dishes in the other one. Same thing when you are slow at unloading a clean load, you keep filling up the other drawer. While the clean dishes sit in the other drawer.
