We bought this dishwasher to replace a 16 yr. older GE model. I expected this dishwasher to be quieter than the older model because it was newer but it wasn't. It's not louder either I just thought after 16 years they would have made some improvements. The insulation wrap was like a thin piece of fiberglass wrap,
The dishwasher itself does a good job. We usually pre-rinse dishes in sink before we wash but sometimes the dishes sit a while before we start wash cycle. This causes food to harden on plates. We’ve had   no problems to date with dirty dishes if we use the steam cycle also. Oher wise a normal wash cycle is just fine.
