Dishwasher about 12 years old.
I think it started with bad smell after washes (which came out perfectly clean though) and I learned to keep the bottom filter clean (I never really knew it was there and just assumed the dishwasher/food disposal took care of food bits).

Recently it was starting the cycle by filling the bottom with water as it should but then stopping. I had to press cancel/start button and that's all I could get the machine to do.

I checked the float sensor on the bottom seemed good.
The clear hose leading to the food disposal seems clean but does have some dark smudges within it but I don't think a slightly clogged exit hose is causing the problem.
I pulled the unit out to get familiar with the pump assembly since that's what researching lead to be a likely problem. But while I had the unit pulled out and ran it, it went through the complete cycle and seemed fixed by itself. I pushed it back and used it a few times no problem except that the bad smell after washes came back quite obviously. So I made sure filters were always clean but it would still smell and now it's not doing a great job at washing. I sometimes have to run it twice and set it for 'heavy, pots and pans', and now it just doesn't wash nearly as good as it should and still smells pretty much constantly.

Try soaking the inside down with apple cider vinegar and I mean soak it down. I always suggest filling up a spray bottle and soaking down everything on the inside, gaskets, anything you can see spray it..let sit for an hour then run an empty wash, repeat if necessary... this usually takes care of this sort of issue.

I think it might have only been a clog in the P trap and the line from the secondary sink. The dishwasher runs into the food disposal under the main sink and there's a side sink that connects to just above the P trap, well the horizontal pvc running from the secondary sink was a tad unlevel in the wrong way. I noticed the side sink was draining slow so I thought it was the P trap. I took all the PVC apart. The vertical pvc from the side sink was almost clogged shut, the P trap was clean. I'm hoping it was simply that when the chunks of food fill the P trap, it enters the horizontal PVC from the side sink and then struggles to push everything up and out the P trap. Thus was getting cloudy dirty water sometimes and the smell was also coming from the side sink (although much more noticeably when the dishwasher was opened, which seems sort of contrary to the clogged PVC from the side sink being the cause which should smell as bad above the sink as the dishwasher smelled.

Anyway, it's being working fine though mostly for the past few weeks from starting this thread, but then just now cleaned major clogging in the pvc so hopefully that's all it was.

Good to hear!
FYI.. Apple cider vinegar is still a good way to clean the inside and drainage of a dishwasher... I have always had good luck with it and via recommending to others.
Glad to hear you are back in business!
