I just had my drain hose replaced on my Kitchen Aid dishwasher because the old hose had sprung a leak. I had called the appliance store (in house repair) where I bought it and they told me it was a plumbing problem and to call a plumber. The plumber replaced the hose. Now, the water does not drain well out of the washer. There is one inch of water covering the entire floor of the washer (not just the drain area). I called the appliance store for their opinion and they said that the plumber probably did not use Kitchen Aid drain hose. They said Kitchen Aid washers have to have a Kitchen Aid drain hose. So I called the plumber. He used a universal hose. He has never heard that Kitchen Aid washers have to have Kitchen Aid hoses. Who is right? I already have $264 sunk into this project. Another $264 would buy me a brand new dishwasher instead of two hoses!

Thanks!

Thanks for responding. What is the drain loop you mentioned in your post that the plumber might not have done when he installed the hose?

My model # is KUDI01TJ. The #8269905 is also mentioned.

I'm glad you think that the brand of hose is not the problem here.

The dishwasher is not right next to the sink. The cabinets are in a U shape and the sink is at the bottom of the U with the dishwasher under the cabinets on the side of the U. The drain hose goes down into the basement and then crosses over under the floor to come up into the cabinet under the sink and connects into the garbage disposal. The hose comes up to the disposal from the floor below but is never higher than the opening. Is that the problem? Should it be raised above that disposal opening somehow before it connects with it? I looked at the manual and there is no "air gap" either on top of my sink. We have had the dishwasher in this location with this setup for 5 years with no back up problems. I did notice that the plumber put a metal clamp on the floor joist in the basement so that the hose doesn't hang as it crosses over to go back up to the cabinet. It is held close against the wooden floor joists. Before it just hung loose. Could this be the problem with the water not draining? Any ideas? Thanks for any advise you can give me!
