Product review (5 stars): Don't waste your time with attempts at diagnostics
After my parents told me that they watched a youtube video on how to fix their washing machine and fixed it... that was when I figured if they could do that I don't have an excuse not to!
Don't waste your time with attempts at diagnostics. If you see the dreaded "OE" error and during drain cycle the noise is a little louder than usual and the machine just gets stuck there: Drain the water using the little hose (open the front door below the main door) it's on the left (you won't miss it)- the little hose is there. You might need a large vessel.  Once drained remove the filter- if there's no clog: - order this part quick, and you'll get it in 24 to 48 hours. Most you tube techs show full pain in the a** disassembly way starting with the top, after getting a hand from a friend dropping the 200lb 2007 dark red LG TROMM on it's side, then I popped the bottom open like I saw in a non-pro video...
Use old school screw driver when tightening new pump into place (else you'll kill the thread and will need to use spare holes with existing screws or go with a slightly larger screw.)  Feel challenged? Take pictures of everything as you disassemble one step at a time. And don't mix up which motor wire goes where!

If you got that pedestal aka storage base under the washer, you'll have to pop the stickers on all 4 plates connecting the base to the washer. Due to vibration and failure of the double sided adhesive tape (hey it was industrial strength a decade ago, but a decade later it's a joke) on the 4 connecting plates, used self tapping small screws to connect the upper part of each plate to the washer's body.

Believe in yourself! You are only 2 hours away from a working washer once you pop the pump parcel open. Ancient people knew how to make their shoes, clothing, dwellings, you name it! This is just a stupid washing machine :)
