Huh. I have a Whirlpool dishwasher and it’s been working fine for over 5 years–no problems, ever.
I also have a Kitchen Aid mixer which is, indeed, the shit.
Add the Consumerist (www.consumerist.com) to your list. They’re now owned by Consumer Reports, I think. If something appears on their blog, generally speaking it gets fixed.
Take it back to Costso. If you have the receipt, they will accept returns for life, I am pretty sure.
This is good advice, as Costco is wonderful about returns! However, by the time the crap started falling apart, we didn’t have the receipt any more. So, two lessons learned: One, don’t buy KitchenAid crap; two, if we buy something from Costco, keep the receipt.
Actually, I’m guessing (if memory serves, and it doesn’t always. . .) we paid under $30.00 for the set. So $30.00 for two valuable lessons is something of a bargain, don’t ya think? 
The Simple Human dish rack we bought at Costco about four years ago, OTOH, though we paid far more for it than I ever thought I’d pay for a dish rack, has been worth its weight in gold! Simple Human’s service department rocks.
Also, given the proper circumstances, Costco can reproduce your receipt. Best to remember that if you’re askng them for such a service, it’s them doing you a favor.
Yes, I always keep this in mind. Once we bought some gummy multi-vitamins from them (the kind made for kids). We’d bought them a number of times before with no trouble. On this particular occasion, though, one of the three bottles we purchased (we had a coupon) turned to gelid liquid in the bottom of the bottle before we could use them! We didn’t have the receipt any longer, but I took it back anyway. I approached the customer service desk like this:
Me: “You probably can’t do anything about this, but. . .”
Desk: “What seems to be the trouble?”
Me: “Well, these gummy vitamins. . .you probably can’t help me because we don’t have the receipt, but. . .”
Desk: “Oh, yeah. Every once in a while, this happens with that particular supplier; go get another bottle.”
I’ve worked in customer service before, and I know what’s most likely to get results. That’s why, with KitchenAid, I started out saying “These pieces have worn out (sooner than I expected them to); where can I order replacement parts?” It was only after several non-answers that I made it clear I would NOT be doing business with KitchenAid again!
OTOH, Simple Human has had such awesome customer service, that I have emailed them, letting them know “I’ve had such great experiences with your products/service that I will buy any item I can from you in the future!”
I believe that, for every ounce of effort you are willing to expend complaining, you should be willing to spend at least that much effort on praise for what’s done right!
Well, from looking at some of the stuff that simplehuman sells, there is clearly a LOT of markup for their stuff…
Of course, there are plenty of places that mark up their stuff and still have crapy service, too, so I guess it’s nice of them to at least treat you well.
Well, I’ll tell you. . .before I bought my Simple Human dish drainer, you would never have convinced me I’d spend $30.00 on a freakin’ dish drainer! (When you can get one for $3.00 at Family Dollar, Dollar General and the like). BUT. . .it’s very deep. I don’t have to worry about stacking dishes deep/high and them ‘overloading’ the sides and tumbling out; and most of the parts are stainless steel, so I can safely put heavy-weight glasses on the cup drainers, and not worry about them overloading the plastic prongs and tumbling to the floor. And the pieces that are plastic can be configured/arranged any way I want, and can be easily removed for cleaning. Add to all this the fact that, when the plastic clamps for my stainless steel cup drainers started to develop cracks, I emailed Simple Human only to ask where replacement parts could be bought, and they would not sell me new ones! Instead, they sent me new ones, free of charge, Priority Mail!
I’ve had my dish drainer for four years, and am delighted with it. If I’d settled for a cheap one, I’d have probably spent $20.00 (on the original, plus replacements), and been aggravated with them much of the time anyway.
So, IME, Simple Human has earned a customer-for-life. Good products+good service are worth quite a bit, IMHO.
