Cove dishwashers

When we built our house, we wanted Miele dishwashers, but it was pandemic times, and Miele was so hopelessly back ordered that they turned off their order system for dishwashers. We purchased Cove dishwashers (we have 2, one in the kitchen and the other in the butler pantry.)

My experience with Cove has been disappointing. They are well-designed and quiet, but they do not clean dishes as well as the Miele and Bosch dishwasher we have had in the past. I have changed settings and read about how to load the machine. One of the advantages of having two of anything is that you can compare one to another; in this case, both perform equally poorly. It's not a water quality issue because our house has an RO system, and the water coming out of the pipes is better than the bottled water.

I talked with a repair tech who was at our house for something else, and he said this is a common complaint he hears about Cove. I'm wondering how Subzero got this so wrong when they made such a big deal about how long it took to develop this product.
