Question about LG Dishwashers
Thanks to other info gathered from this site and
a few quality hours with the washer, I solved this problem for myself.
I experienced the same problem. Did the same things. OE error Drain pump would not drain. Sounded like it was grinding a bit. Just not draining. Checked the strainer. Nothing. I found this link to the service repair manual which has easy to follow instructions on how to disassemble the washer and get to the pump. Removing the door and the pumps is really not that hard.
Don't be scared. I'm a novice and it was easy. Wear gloves. Lots of sharp edges. All you really need is a screwdriver and pliers to remove hose clamps.
Anyway, I got the the top cover off, removed the front door panel section and could easily access the drain pump. I first pulled off all the hoses. All clear. Disconnected the pumps (easy once I figured out the clip the pump unit slides into). Note there are 2 pumps - a circulation pump and drain pump (larger one). All clear. Reassembled. Still nothing.
Ran a few loads of wash manually draining after each cycle (to keep the wife happy with clean laundry). Yes, you can do laundry while waiting on the part to be delivered. Just get a bucket and drain the washer after each cycle - easier if you pull off the main drain hose and drain it that way versus the little emergency drain slow (slow!).
Became convinced it must be the drain pump so I ordered a new one for $50 here. repairclinic.com
Installed new pump and reassembled machine in about 20 minutes. Worked great. NOW HERE IS SOME ADVICE THAT MIGHT SAVE YOU THE $50 for a PUMP:
After replacing the pump, I was banging on the old one to see why the heck it stopped working. During the process, I figured out how to actually pull the pump apart. There is a rubber washer around the housing below the blade - pull on it hard enough and the pump slides apart. When it did - holy cow! It was filled with grimy sandy muck. I cleaned it all out, but did not feel like testing it to see if worked. So I likely have a spare should the new one ever go out.
Hope this helps.
