My 8 year old Kenmore Elite washing machine 110.20992991 makes an awful clunking/grinding noise when it is the spin cycle prior to the rinse cycle and also the final spin cycle. It fills and agitates fine and is nice and quiet.
Here's the sequence of what I did based on trying to trouble shoot the problem myself by reading some of the blogs posted on this website and reading the Sears repair manual.
1) I bought the Sears manual and found some Whirlpool education manuals for technicians.
2) Found 4 destroyed agitator dogs in the top of the agitator and replaced
3) Removed the motor coupler which while the rubber holes were a little elongated was still serviceable. I replaced it anyway with a new one.
4) I found no other pieces or grindings or powder under the machine
5)Restarted machine & still same clunking/grinding noise. Noticed the agitator is still operating when in the spin cycle and seems to go in overdrive as it is spinning faster than any of the agitation speed settings on the washer.
Decided to tear the machine totally apart down to the bare bones.
6)Found no obvious damaged parts example plastic tub block, clutch and brake assembly including the white plastic brake cam driver looks good.
7) Next dismantled the transmission and examined the spin pawl trip lever and latch pieces. I found the end of the spin pawl to be mashed down some. From a prior blog on someone elses machine they said to replace the spin pawl in a case like that so I bought a rack retainer rebuild kit with all of the parts the spin cam, cam lever and latch and replaced all of these pieces.
Note: When I took the transmission apart and replaced the parts described in 7) I did not take apart the end of the agitator shaft that goes into the transmission so I do not know if there is anything wrong in the area of the agitate gear, cam follower or agitate cam. I also really did not stare at the shift actuator but did not see anything unusual.
Everything else inside the transmission appeared fine so I reassembled it and you guessed it same thing happened same clunking/grinding noise when in the spin cycle with the agitator spinning like crazy. When operating the washer with the cabinet off the noise sounds like it may still be in the transmission or around the clutch brake area. If I push down on the top of the agitator while it is spinning in the spin cycle the sound gets dampened somewhat but is still there.
I have not checked any electrical items when doing the above diagnostics.
Anyway I would appreciate some guidance on what to do or check next I took the day off and would like to get this fixed today if possible.
