greta, here is my answer to a similar question "if it won't drain check this items according to the Service Manual from here
1. Check Wire Harness connections.
2. Check Drain pump.
3. Check Drain pump motor.
4. Check that the Drain hose and Drain Pump Filter are clear of foreign objects.
5. Check the CCU.
Page 52 of the same manual tells you how to run a diagnostics. See what error code you get on your washer. Of course when you get to the drain pump (available here) check the inlet and outlet for missing socks ;-) etc. sometimes you will find the weirdest things in there." Hope this helps, good luck.
