Samsung Front loader, error message nd, wf330anw / xaa 01

Hello,
I use this washer a lot. I'm getting an nd message and the washer won't drain at all, even after cleaning the filter.

So I discovered that if unplug it between loads it will drain normally.

If I don't, it won't drain at all.


Any idea what this could be?

I don't want to pay $75 for a service call if it's going to be a big job. But I'm a full time student and single mom and would like to fix it if it's reasonable.

Could it be a simple fix?

Thanks!
Kris
