My Kenmore Washer Elite HE3, front loaded, makes a very loud knocking noise when it spins ?

Check the tensioner pulley that keeps the belt tight. It is next to the motor and the bearing may be shot.

the plastic is the drum has dropped so its eating a way the plastic on the back of the drum so no not worth fixing the mould is an easy fix just soke a cloth with neat bleach and leave over night make sure you do a rines after woulds as you don't want bleach on your cloths ok

Read the article by RSteve!!!

Check the Vibration damper rods to be sure that...
1. They are there and mount is solid.
2. If they are broken in 1/2.
3. The plastic knuckle mounts are not missing/broken.
4. There is oil in the shock absorber/spring section of the rods.

Also - there are suspension springs on the bottom of the tub that could be broken and/or missing.

Replace/repair as necessary.

it could be the drum is not in place

yes!! the F/11 is triggered under high voltage conditions like high speed spinning. The part is called the MCU motor control unit. if it goes into failure while using your machine and locks the door, just wait 3 minutes and the door will unlock after the MCU resets. Try using you machine with a low speed spin for awhile.

It could be that you are not setting the water level high enough when you do large loads.also the strap that holds the cement block could have come undone and now the block is unsecure.

Remove the lower front panel 3 screws across the bottom. Pump will be behind this panel.

Your problem may not be a broken spider assembly. My Kenmore Elite (model # 110-42822-203) had a kocking problem as well. After taking the back off, I discovered that the nut holding the pulley to the drum shaft (on the outside of the outer basket) was slightly loose. I simply re-tightened this an the knock went away. The pulley was shifting on the shaft ever so slightly, leading to the knock. Cost of fix: $0. :-).

Ours started knocking several months ago and then progressed to a high pitched sound when in the spin cycle. I manually turned the drum and heard and felt a bearing roughness. I lifted the drum assembly and felt a fair amount of play, which I think the initial knocking noise came from. On the sears web site a new rear drum mount cost 293.00. Today we went and bought a LG model wm2455hw at Home depot, on sale until 2/20/08. I couldn't see paying to repair a machine that only lasted four years.
