I'm having issues with my dishwasher where they dishes are just not getting clean. I checked out a few things and it looks like the drain hose is very dirty, and likely not pumping out all the dirty water before it bring in new water for the next wash / rinse cycle.

My issue is I don't really know why this is happening. I've got the high loop installed under my sink so I don't think that's the issue. Is it possible the drain hose is too long? I need to buy two standard ones from Home Depot (10ft I think) to make it reach from the dishwasher to the sink. That's the only thing I can think off, but I don't want to try a somewhat difficult solution (where I simply extend some plumbing behind the dishwasher so the drain hose is shorter) if that's not the issue.

EDIT: I did replace the dirty drain hose about 6 months ago as I thought it was just the fact that the old owners hadn't done that in a long time. However, it's just as dirty again in that short amount of time.
