The biggest fault with dishwashers is that something small gets in the drain pump and jams the impeller, just remove the item and it's all good.
The second biggest fault is that someone uses normal dishwashing detergent in them and they over suds and then overflow, this causes a small float switch under the machine to cut the machine out, and usually the drain pump runs all the time.
This happens a lot when people have had a party and some good samaritan decides to load the dishwasher and start it for you.
The best way to kill the bubbles is to add some hair conditioner into the machine, it works really fast and that's what most Hotels do.
I once did a house call and found the drain pump blocked, I stuck my hand into the dirty water and I pulled a used hypodermic needle out of the drain pump. I was not impressed.
Another time I stuck my hand into the dirty water and found they had filled it up with hydrochloric acid to try to unblock the machine, that burnt.
