Product review (3 stars): Great easy DIY kit, but mine was missing a couple pieces.
My troubleshooting was a dishwasher that wouldn't drain at all, and wouldn't pump water through the wash cycle. I could ask it to Cancel/Drain, or to run a wash cycle, and all I would hear was a mild hum and it clicked off; then it hummed and clicked off again.

Not knowing any better, I unhooked it, took it outside, and dumped the water... then started looking to find what was broken/jammed. Upon disassembling, I found that the shaft of the main impeller was broken, and that the chopper blade was beaten up, along with the spring being broken. The culprit was a metal nameplate from Kitchenaid, which was all bent/chewed up. (Maybe from a spatula or cheese grater? Meh.)

Well, I wish I had found this really good video first: [...] does a great job showing how to do the disassembly and reassembly with this kit. (If Amazon doesn't allow the youtube link, search youtube for "Dishwasher Repair - Replacing the Drain and Wash Impeller Kit (Whirlpool Part # 675806)" by PartsSelect.) If I had seen the video first, I would have simply scooped out as much water as possible, and used towels/rags to get the rest of the water out. YOU DON"T HAVE TO UNHOOK YOUR DISHWASHER! I would unplug it before you work on it though!

SO. Great news! You can fix your dishwasher, and it really is almost as easy as a few screws/bolts if you are a little DIY/handy.

I would have given this kit 5 stars, but I was missing a few pieces and I had to reuse the old ones. I wondered a bit when I opened the box and the bag had a hole in it already... did someone return it minus a few pieces? (Problems with MY kit: Missing Bolt, Missing Chopper Blade, and the smaller gasket was WAY too small.) I used the old pieces in those places and it worked out fine in the end, no leaks.

This kit is WAY WAY WAY cheaper than a new dishwasher!
