F02 Error Code on Whirlpool Duet & Kenmore Elite Front Loaders

Guru...like my daughter would say "YOU ROCK"! Well, I did what you said and I found a hair tie clogging the pipe and quarters in the trap. Thanks for the great advice..you saved me $50 and the wait for my home warranty repair person.

Just finished up the instructions you have posted. Thank you very much for saving me the time and money for a service call. Very easy to do and I found a "rotten sock" in the filter. Now the mildew odor is gone and machine does not have the SUDS problem like before.

THANK YOU !!!!! and thanks to my 15 yr mechanically inclined son...he did do what the instructions said but we couldn't get 00 so we did the drain/spin option. tub didn't drain. so we started from step one to clean out pump basket & then we attached the wet/dry vac to the discharge hose and you could feel some kind obstruction release...I'm pretty sure the obstruction was the rubber backing from area rugs that after awhile dries out & gets brittle and when wet.....falls apart in the washer & can plug everything up.

so advice to all you people out there.....when an area rugs rubber backing becomes dried out...its cheaper to replace the rug then have to replace parts on a washer.

Its great knowing that this website is here & experts like jsrock516 is willing to share his knowledge to help other people out...

Thanx JSROCK516 !!!!

JS you Rock ! 
I'm the guy that would have taken the drain plug off and had a gallon of water on his hardwood floors.
So after removing the water, I took the plug off and found a nickel, penny, and a pen cap that must have been stuck in the impeller of the pump. The cast iron rod for the impeller snapped. I'm assuming from the pen cap getting stuck. 
So I'm off to get a new pump. Thanks for saving me the call to the  Repair man. 
You Rock!
