Sandra: According to ShopYourWay.com:
"The E20 error code is a class code that indicates a drain problem in the washer. This is consistent with the drain and spin problem that you are observing. To determine the exact error code, follow these steps:
Wake the machine by pressing any button
Wait 5 seconds
Press and hold the START and PAUSE/CANCEL buttons simultaneously
The exact error code (E21, E23 or E24) will be displayed.
If E23 or E24 are displayed, you will normally need to replace the control board due to a failed drain pump relay.
If the E21 code is displayed, I recommend that you follow these troubleshooting tips:
Check the washer drain to see if it is clogged.
Check the washer drain hose for a clog or restriction.
Make sure that the washer drain system complies with the installation instructions for the washer.
Try to gravity drain the washer by placing the drain hose in a bucket on the floor. If the washer will gravity drain, you may be able to
unplug the washer
and remove the bottom front service panel using the procedure in the image below. Arrange towels to catch residual water that may be in the washer and check the pump filter and drain trap for a clog or debris. If you find no clog or debris, then you may need to replace the drain pump. NOTE: You should not attempt this procedure unless you are completely confident in your technical ability to safely access and check the pump. Do not disassemble the drain pump hose if the washer is full of water. " There is also a video that may help you, Sandra: https://www.youtube.com/watch?v=s0Wrc2LiCK8
