I found fix online and it seemed to be the exact site I was looking for. I entered my dishwasher's model number and was shown a diagram to choose the part I needed and I ordered the parts. I got a box quickly but as quickly realized they sent me the wrong parts. Also, they appeared to just dump the parts in a box and then sent the box to me.
So I called the customer service number, explained the parts were wrong and they said they needed to make a claim with their warehouse. A half dozen emails later they simply stopped emailing. I waited nearly two weeks and called again. Now they said I need to wait two more weeks for the warehouse to decide if they want the parts returned. Until they decide I don't get my refund.
I would choose another site simply because they can't put customers first and if you need to return a part you better saddle up for at least a month of hassles. Not worth it.
