Lg ABT72909202 Pump Casing Assembly (Pump Housing) OEM Part

I suspected the 'circulation pump' to be the culprit. I could not find a 'circulation pump' so I deduced via the picture schematics it must be the 'casing assembly, pump' I found on the website. I have heard there have been issues with the 'drain pump' so I also ordered the 'case assembly' on this site which is an odd name for the drain pump. Boxes came with just the part inside no instructions or other info. This was fine as I have been diy repairing things my entire life. I made sure my parts were the right general shape and appearance and I set to work and began disassembly of the dishwasher. This required removing the dishwasher from under the cabinet first. These types of remove and replace repairs are generally simple, just remove things and replace them back when done. One thing you need to do with the Casing assembly is transfer over what appears to be the thermometor unit. Unscrew the center nut which loosens it's hold and pull it out. I used two flathead screwdrivers to get an even pull on the thermometor. I also lubricated the gasket with crisco when I reinstalled it into the new casing assembly as I could tell it would not want to go without some lubrication as it is a tight fit. Screwed in all of the screws, hooked the wiring back up, hooked the plumbing back up and reinstalled it under the cabinet. First tests are successful, dishwasher is again quiet as a whisper.

Replaced the pump assembly.
