LG WM2233H* Clogged drain

I have an LG washer and apparently my drain is clogged.  I'm able to drain the water out using the hose at the bottom but when I finally get all the water out and open the drain pump filter...its empty...but still getting the OE code?

After draining and cleaning filter, reset washer--Unplug unit and hold Start (selector) button for 10 seconds. Plug unit in and restart.
