GE Spacemaker Washing Machine Not Draining

Model: WSLS1100H0WW

I was given this combo unit a while back and it recently stopped draining.

Upon troubleshooting, I found:

* It will spin if select “Spin Only” and there is no water present.

• If I put the hose on the ground, it will siphon drain. (I brought it outside to troubleshoot and I ran it with clean water, no soap)
• The drain pump makes a humming noise
• The drain pump is not clogged with anything
• None of the hoses going to the drain pump are clogged.
• I recently purchased a replacement Official GE drain pump and it still will not drain
• The washer is able to detect when the lid is not shut because it beeps to close lid when it’s running a cycle. I’m not ruling this out, but it’s at least a little functional.

After a while of the washer not draining, it says “Drain” on the display. Basically it wants me to drain it so it can advance to the next cycle.

So, before I start buying more parts, I want to ask the friendly people of ifixit!
