Hoping for some ideas please! .....our washer gets stuck at the spin cycle and won't drain; accompanied by the OE code. I've removed the drain pump to check for obstructions and bench checked it for power. I've checked to make sure the drain hose isn't clogged or kinked; I've even cleaned it out, though there wasn't enough junk in it to be a problem. I thought maybe the main control board was possibly not giving voltage to the drain pump ( I grasped at that only because the wife said the washer controls had locked up on her and/or didn't respond); I replaced the main control board and still have the same issue. Anything else I should check? At my whits end, here.
Thanks

Hi,

I found this here that I hope can help.

our washer gets stuck at the spin cycle and won't drain

Is the drain pump running?...getting power? No power and we likely have a control or wire issue. Power to the pump but no pumping is likely a pump issue.

Hope something here helps,

Thanks for response, Jeff. I did find that info on the LG site. I put AC voltage to the drain pump when I had it out on the bench and it ran. Do you think I should put a voltmeter to the connector at the pump to see if it is getting voltage when the spin cycle starts? If it is not, I'm assuming the problem would be from the main control board; which I replaced. Thanks for the help,

I thought I saw somewhere that the lid lock switch could be a possibility. Did I read that right? If I can hear the lock engage (and lid physically seems to be locked) does that eliminate that theory?
Thanks again.

Doesn't mean anything when it is not under stress like a tub full of water.

Yes.

If it is not, I'm assuming the problem would be from the main control board; which I replaced

Or a broken/loose wire between those....wire diagram -might- also help to tell you what else is between the pump and board.

I didn't see that, but nothing should work if t he washer things to lid is open.

Thanks Jeff.

Sooo.... it ended up being a broken wire at one of connectors on the two-wire harness for the pump. I removed the two connectors from the pump and disconnected the connectors from the main harness to the two-wire pump harness. I did a continuity check of both wires. The wire casings themselves looked good so I removed the plastic cover of the female connector to find that the wire had separated from the crimp. Too bad I didn't find this forum before I jumped to the wrong conclusion and bought a main control board and installed it.
Thanks for the help, Jeff!

Good catch!
Glad that was all it was
Thankx for the update.

It was your tip about the loose/broken wire that sent me in the direction I went. Like I said, wish I had found this forum 4 or 5 days ago before I had a control board in the mail.
