Product review (5 stars): Very doable job, working washing machine after OE error
I had been receiving the dreaded OE error on my LE WM2010CW intermittently for some time.  I was able to unplug the washer to reset it or clean out the filter and be back in business.  However, the last time the error arose, I could not get the machine to finish a cycle and manually draining the machine has pretty much ruined my wood floor.

Like others, I did some reasearch and determined the nature of the OE error--the drain pump had failed.  Before ordering the part, I was confident there were no blockages and I watched several YouTube videos of others making this repair and was confident I could handle the task.

The process of installing the pump after disconnecting and draining the machine is to remove the screws holding the cover of the machine, (located on the back of the unit), sufficiently removing the front control panel to get access to the screws holding on the front panel of the unit, removing the spring clamp securing the door gasket, the door sensor connector and eventually the pump.  Washing machines aren't that complicated.

I found my unit disassembled slightly differently from the YouTube videos.  If a part wasn't coming off, locate what is keeping it on (usually a hidden screw) until everything is out of the way.  The hoses and harnesses for the pump came off pretty easily and i and I used the opportunity while the unit open to clean out the inside, which had accumulated some grime and soap that I presume overflowed from the detergent drawer.

The pump itself was easy to replace and overall, the process was pretty intuitive once I understood how to get inside.

I was able to do the entire job with a Phillips screwdriver and a set of pliers.  I was concerned about replacing the spring clamp that holds the gasket for the main door.  It took a little bit of adjusting but forming rings with zip ties to pull the spring instead of the special LG pliers worked great for me.  I also learned that the polarity of the motor connection doesn't matter when you replace the connecting wires (but I marked them when I took them off just in case).

Delighted with the outcome.  My washer works perfectly now.  If you can use a screwdriver and are organized and methodical to keep track of the screws and the order of things, this is a doable job.  Hardest part was I stacking and moving the washer out of the laundry room so I could access it.  The actual dismantling, installation and reassembly took a little over an hour and it I had to do it a second time, I could probably handle the job in 40 minutes.  Sure I saved at least $300 doing this myself and did not have to wait around for a service call.
