My whirlpool duet gets to the spin cycle and gets to the super, fast speed and starts to shake Is there anything I can check before getting a repair person involved?

Hi Paul, first piece of advice is to make sure the loads of laundry are consistent. A pair of jeans or a bath towel in a load of lighter clothes can cause an off balance condition, causing the machine to constantly try to re balance the load and never reaching high speed spin. Other than that,make sure your spin speed option is set to high. If those don't solve the issue,contact a local repair company to come out and take a look. Hope that helps.

Possible Defective washer transmission. Do you overload the washer with heavy items like towels or blue jeans very often? That can cause early failure.

Almost certainly faulty bearings check for vertical movement in the drum if so, not good very expensive repair

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.

Check wire harness connections between the Drive Motor/Tachometer and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU)
Check the Drive Motor
Check the MCU
Check the Wire Harness

I have a 7 year old duet washer. It started to shake during the spin cycle. It is level and the shocks and springs holding the drum are working. When the washer gets to the spin cycle, it is apparent that the drum is off center.
I tore the machine apart and found that there is a bracket at the back of the drum. This bracket sits in water so it was covered in slime. I found several large cracks in the bracket. Once these cracks occur, there is now way the drum can spin correctly. The bracket is welded to the back of the drum, so it has to be completely replaced.
What a poor design. I would guess that many, many other people will be seeing the same problem within a couple years. I was lucky in that I did not pay for a repairman to try to fix it.

Careful of overloading the front-loading washers. Too much of this will result in the bearings in the drum to go bad. When this happens, the rpms on the drum slow down due to belt slack. You can only see this with the back off of the unit and in the middle of the cycle. They do not sell replacement bearings...you'll have to buy the whole drum (bearings pressed inside) and for 1/2 the cost of a new washer. I hate front-loaders. I'll never buy one again.

Press 'end of cycle' for over 3 seconds. Perhaps you have to check your filter, maybe clogged.

bad motor most likely. easy fix

Just wondering: did the technician also replace the motor control unit? Or is that the 'spin unit' that you mentioned?

See pages 4-7 and 5-4 in the repair manual.
