The spin cycle will not balance at high speed. The machine wants to vibrate extremely!

If the problem is vibration when in the spin cycle, you probably have either bad drum bearings (there are two and a seal) or most likely a broken drum spider ( only available for Kenmore as an assembly with drum included ) ,this repair can easily exceed 400 bucks just in parts, it is a very common problem with this machine because the aluminum drum support corrodes and breaks one or more of its 3 arms causing the vibration in high speed operation.

The machine uses automatic load sensors to balance the load and when you put something in the machine that is big, like a comforter, it knows that it cannot balance that item. So with a front loader it wont spin at high speed because it would be off balance and either damage the machine or the machine would "walk" because of the off balance motion.

I can't offer a definitive answer but I have had a little experience.

It is possible it is spinning too fast. The brain of the machine needs to know how fast the motor is spinning in order to control the speed. The motor is fitted with a tachometer sender for this purpose. It is important any replacement motor is fitted with an identical tachometer to the original.

The brain is programmed to cycle the spin slowly at first at increasing speeds to allow the washload to settle and for most of the water to be removed so when full speed is reached there will be less vibration. Perhaps the cycle is incomplete or absent and it is starting on a high speed spin...

The washtub suspension can become worn and weak even though it appears intact...

It is conceivable the drum is imbalanced - a drum that is nicely balanced will not vibrate when spinning without a washload.

Hello !

It's possible to be the shock absorber worn out.

I've just uploaded a service manual.

relevant info pasted below: --

Regulate a specific spin speed that generates excessive vibration and noise as follows:
1) Put an unbalance part (rubber) inside of the drum.
(this is a special weight that service people use. It clips into the drum. If you don't have it, throw in about 4 to 6lbs of damp laundry.)

2) Start the QC test mode (Refer to section 7-2).
7-2 says turn the washer off, then press 'spin speed' and 'soil level' at the exact same time. Then, while holding both buttons, press power to start "QC test mode"

3) Press Delay Wash button, then ' tst ' is displayed on lcd
4) Press the Spin Speed button repeatedly to select Extra High.
5) Press the Quick Cycle button, the spin speed is displayed.
6) Press the Start/Pause button.
7) Press the Beeper button repeatedly to set spin speed (600, 800, 1000, 1200 rpm) and check if there is vibration
and noise.
8) If there is no vibration and noise, increase the spin speed by pressing Beeper button.
9) If there is vibration and noise, rotate the Cycle selector knob clockwise to reduce the Spin Speed (reduce by 50
and 100 rpm). In case of 600 rpm, it can not reduce the spin speed.
10) If vibration and noise are reduced, press the Quick Cycle button to store (2 beep sounds).
* If you want to return to factory default spin speed setting, repeat above steps except step 9)

Typically this is due to either having an VERY uneven (weight) load, (like having a blanket shift all to one side) or the washer needs to be levelled physically (like balancing a car tire.. high speeds tend to show imperfect weight distribution).

Because front load washers are VERY HEAVY, they shake if you have a wooden floor. If your front loader sits on concrete and it still shakes, then you have to make sure all is balanced. If it still shakes, then inside the system there are shock absorbers that need to be checked.

make sure you have all the shipping material out of unit..4 bolts in back and styrofoam under tub if so ,then get a adjustable wrench ,,,put unit in drain spin cycle or spin cycle only..when unit gets to fastest spin ,,thats will come when its about 8 minutes left..tighten each leg lock nut on unit until unit stops vibrating..only turn the lock nut not the leg..only adjust lock nut on legs in high speed spin

(I know this is an old question, but its probably a common question for new owners - including me a couple of weeks ago...)

Power the unit back on, press the spin speed button and it will select the "drain and spin" cycle. Pressing the spin speed button again will select different spin speeds as well as just "drain".

Something you might try instead of medium spin speed is to turn on "SpinSense". To turn this on (and off), press and hold the "Stain Cycle" button for 3 seconds while any wash program is in process.

What SpinSense does is measure the imbalance by doing a very slow spin before cranking the spin speed up (and measuring how constant the very low spin speed is). If the balance is out too much, it will stop, let the clothes drop, and then try another slow spin. It will try this over and over many times until the balance is decent. Then it will let it rip. It makes a huge difference, but it can spend a lot of time getting a good balance some times.

SpinSense also seems to be able to detect if the machine is shaking terribly, shut the spin down and try again.

Our LG 2688 is on our 1st floor (wooden floor). Without SpinSense, the vibration was terrible and with it, it is tolerable.

For some reason we typically get less vibration with "Extra High" spin speed compared to "High" so that is another option you might try.

Had the same problem but the motor pump was loose
