What's the meaning of the E20, E21, and E24 error codes on my Kenmore washer model 41744092500?

My washer Kenmore #41744092500 not draining. First,it showed E20. then E24 . I pulled the outer hose in the back and put it in the bucket, it drained a little, but the inner hose didn't drain until I open up the back. When I test to use the drain cycle, I can hear the buzzing sound and it stops draining and the BUZZING sound is ON. Now the error code is E21. Please tell me, do I need to replace the pump or circuit board?

The E20 is a group error code that indicates one of the following problems occurred:

E21 - Water did not pump out fast enough from the washer

E23 - Drain pump relay on the control board failed

E24 - Same as above, drain pump relay on the control board failed

To determine the exact error code, you can use the procedure in the first image below to recall the code on the display.

If the code recalled is E23 or E24 then the electronic control board in the washer will likely need to be replaced. If the code is an E21, then I recommend that you take the following troubleshooting steps:

Check the drain hose of the washer for kinks or clogs.

Check the washer drain to see if it is draining properly.

Make sure that your drain hose is installed properly to prevent siphoning of drain water back into the washer. Check to see if the drain hose is stuck way down the standpipe behind the washer. If it is then I recommend pulling it out so that it only protrudes down the stand pipe about 6" to 8".

Unplug the washer and remove the bottom front service panel as shown in the second image below. Arrange towels to catch residual water and check the drain pump for clogs or restrictions. NOTE: You should only conduct this check if you are completely confident in your technical ability to safely access and check the pump.
