Product review (3 stars): No matter how hot the water is, the detergent ...
No matter how hot the water is, the detergent doesn't fully dissolve, so have to run an extra rinse cycle.
This was powdered d/w detergent.  So, I bought the liquid d/w detergent, and then the detergent door didn't open during operation!
So, I had to manually open the dispenser door, and run it again.
