Product review (5 stars): Designed to fail
I also bought a Kitchenaid, based on my experience of decades of reliable, high quality product ownership.  If you are reading this,  you already know what a complete piece of junk your dish washer is because you're once again repairing the thing.  My upper dish rack height adjustment mechanism self destructed after only one year, sending small pieces of plastic into the water flow.  Of course they ended up in the food chopper and thus, trashed the blade and plastic shaft assembly.  Whirlpool refused to send the part, even though I was offering to repair the dishwasher myself.  They wanted to order a service call, at their expense, which I have no time for.  Back to this part, thanks to Amazon, it's here at a good price and free Prime shipping.  The new part looks exactly the same with no structural improvements so Whirlpool continues to put out inferior parts to go perfectly with their inferior products.
