We have two dishwashers....
an Amana built in the kitchen
and a veteran Kenmore mobile in the Basement. The Upstairs one gets used
for everyday stuff the basement one is used whenever I am preparing stufff
The Amana takes about an hour the Kenmore just shy of 40 minutes both clean
as well as each other....
When I get mobile again will look at an under the counter dish machine ...
full rack 3 minutes
