This is, by far the worst dishwasher out there. 
1. The bottom rack falls off the track every single time I open it. 
2. The glasses put on the middle rack never got clean and I have to wash by hand after. 
3. The top rack does not clean anything. I stopped putting silverware up there. 
4. We get constant error messages. 
This was a new dishwasher and it hasn't worked properly since the moment we got it.
