My dishwasher didn't drain today. It makes the sound as if it is trying to drain but the water doesn't drain. I unhooked the drain hose from the sink pipe and let the dishwasher go through a drain cycle. Only a few drops of water came out. I'm not sure if the hose is plugged with something or if this is a mechanical problem.

I'm thinking I need to get at the drain hose where it attaches to the dishwasher itself. Then I can replace the hose and run it through the drain cycle again to see if there is a plug in the hose. Is this at all possible, to get a plug in the hose?

If the hose cannot get plugged then I assume I would need to take the drain apart to see if there is something plugging it up inside.

Given that the dishwasher sounds like it is trying to drain itself it seems to me that there must be a plug somewhere. I just wanted to see if my thinking is correct here and that I may not need to replace any of the parts, except maybe the drain hose if it can get plugged. Could the dishwasher still make the draining noise and still have some mechanical issues?

Thanks,

Okay, so I took the drywall off in the garage and there is a wooden wall there. I did not expect that. I guess since it is somewhat of an outside wall I can understand it. I'm just used to interior walls I guess. So that plan has come to a halt.

Currently I am taking the dishwasher apart to see if there is something blocking it from draining. I have taken the bottom sprayer arm off and have gone down a few levels from there.

There is a gray circular piece that is about 1/2 inch thick with a top and bottom disc with vertical pieces every couple of inches running from the top disc to the bottom disc. This is as far as I have gotten and now I need to figure out how to get further into the pump as I cannot get this disc part off. Maybe it just takes more force than what I have used so far but I want to make sure that I don't break anything. :)

Thanks,
