F21 error code and washer will not drain and spin
I hope that I can help you. I had the very same situation today 9/1/2009. After working on it for quite some time and thinking that I may have to replace the Central Control Unit (CCU) it is back to normal and working just fine.
Our original trouble indication was that the washer stopped somewhere between starting a load and what should have been spinning and emptying. We didn't know what a trouble code was early today...now we know a lot more about the system and how it should work. I called Sears about a tech. coming out to repair it and they quoted me $129.00 service call plus parts minimum. I asked them if the people were experiened and they said that they didn't know who it would be or where they would be coming from and they named four towns/cities where they could be coming from. I don't mind paying for quality service and a super tech, but I decided I wasn't going to pay for just anybody and not knowing if they were experienced or not.
First thing I did was to clean out the drain pump filter. it's located under the bottom front cover. you need to remove the three 1/4 inch screws located at the top of this cover. the maintenance book is located inside this cover also.
Pull the cover out to the front and set it aside. Inside is a large round stove knob looking item. this is the drain pump filter clean out. Taurn it counter clock wise (left) to remove it. You may need to catch some water when it gets loose. I packed three towels under it and saturated all. I found a 8 inch long platic ty-wrap, a plastic flosser, a paper clip, two sheet metal screws, a hairpin, matchstick, two rocks, earring, a foam earplug, .380 bullet, (lead only) and a chemical hand warmer bag along with some messy stuff. I cleaned the filter and inside of same throughly.
That may be all you need to do to get it back working. Put the drain filter back together and the bottom cover on and try it. Good luck at this point...I wasn't so lucky. Mine didn't work and the symptoms didn't change. I went through the book and found nothing to match my washer situation. The code I had was a F21, but the symptoms didn't match. It would not fill the tub and wouldn't start. I found the internal water valves would not operate to let water in...the dispenser motor was stopped in position III and not moving. My symptoms were a combination of code F21, and some of codes F27, F28, F30, and F01.
The book states in many places "Verify CCU operation by running a Diagnostic test or any cycle." I ran the diagnostic test so many times I can do from memory... I still kept getting the F21 display error code.
I finally stopped doing the diagnostics tests and tried something else and it worked. The CCU unit must have been in a situation which it couldn't change correctly.
I unplugged the washer for two minutes per the book. Plugged it back in. Then I attempted to use the washer as if it wasn't broke. I went through each wash cycle and each one failed and gave me the F21 code. Continuing with each cycle...if it failed I pressed the stop button twice and turned the power off. Then I attempted the next washing cycle...each one failed and gave the F21 code.
Then I went turned the washer on and went to the "Drain and Spin" cycle which is the same one used in the dianostic mode...but I didn't enter the diagnostic mode...rather I just pressed the "Start" button. Victory was so sweet! The tub started to turn, the motor for the dispenser moved to another position and it seemed to be better. I let it spin for approximately two minutes. Then I put it into the 'Normal/Casual mode and pressed start. everything worked as it should and the codes were gone. It works just fine.
The CCU wasn't working properly as long as I kept attempting diagnostics, but when I started the "Drain/Spin" mode something in the processor changed and it worked as it should.
I hope this helps someone else. At one point I came very close to ordering a new CCU unit...but kept testing/trying things and am glad I did.
Good luck to you and may the good lord take a liken' to ya'.
