Product review (5 stars): This fit my LG Dishwasher LDF7551ST perfectly.
We had been noticing for a few weeks that there was some- but not a lot- of water left in our LG dishwasher (LDF7551ST) after every use.  I cleaned out the drain lines and filters, but there was no improvement in the issue.  After every time we would run the dishwasher, I would have to run the drain function manually to rid the dishwasher of water.  I'm annoyed that this dishwasher has already had this kind of problem after less than 4 years of use, but this review isn't about the dishwasher- just the pump.

I had a feeling that this would be a very expensive repair if I called a service tech.  A little research online and some youtube videos later, and I discovered that I could easily replace the pump on my own.  Yes, it's not rocket science!  I am a small woman, and it took me less than an hour to remove the dishwasher from the cabinet, remove the pump, install the new pump, hook everything back up, and put everything back in the cabinet.  This pump works flawlessly for my dishwasher.  And it's quiet, too!  (*install tip- use vice grips to easily open those spring clamps!)

So if you're having drain issues with your LG dishwasher, skip the service call, save some bucks, and buy this pump.  It's easy to install, and makes your dishwasher run like new.
