I have the kenmore elite h3, and had the same problem. Eventually it stopped draining, very bad smell. Called to get it looked at, which was not easy task since we live in a rural area. Sent complaint letter to company.

Now here is what I found out:
I had washed a few kitchen rugs etc. in the past. Don't do this. The tech tilted the machine back, and removed lower panel. Unscrewed some sort of "trap", and use a wet dry vac. Disgusting odor, and it took him over 15min. to get all the junk out. There was even a pencil in there. He told not to use Gain detergent. Washer works fine now. If this happens again, my husband and I will definitely try to do this ourselves (tech. cost $160). If the machine does not drain, which will eventually happen if this "trap" gets clogged, the machines "computer" will sense it, and it will no longer work.
Hope this helps
