I've got a barely 3-year old Kitchenaid KDTE104ESS1. It wasn't washing the dishes properly. Sometimes the soap packet would be just sitting in the bottom of the dishwasher at the end of a cycle and the dishes would still be dirty.

I cleaned out all the filters and the spray arms. I replaced the turbidity sensor and inlet valve. That didn't fix the problem. I called a repair guy and he said the only thing he could think of was the full pump and motor assembly.

I decided to just replace the entire pump and motor assembly. Now it seems to run through a full cycle and clean the dishes but they aren't dry at the end.

When I remove the filter at the bottom there is still a good cup or two of gray water in there. If I hit cancel (drain) that last cup of water drains out fine.

Also the heating element looks like it's corroded. It used to be a solid dark gray now it has patchy spots on it. When it's running the heating cycle to dry the dishes and I open the dishwater the element is not at all hot. However when I open the dishwasher during the wash cycle the water seems plenty hot and steamy.

HELP! I just want to buy a new dishwasher but I feel I'm "pot committed" because of all the parts I've replaced so far.
