I have two different front load washers. One is the common Whirlpool duet style and the other is the GE gfwr4805f0mc with the adaptive vibration control. Which I don't believe applies to this scenario. Regardless, I have replaced the bearings in both machines as well as the dampers and the springs but both of these units, when empty, have a very powerful yet compact (not a lot of moving around) vibration to them at high speeds. Again, that is when empty. Also when ramping up speed at the very low-end (around 200 rpm on the GE) they wobble enough to bang around with two to four strikes against either side of the cabinet before straightening out. This is when they are empty!!! Even worse when clothes are in it!!!! I have looked at everything from the pulley on the Whirlpool duet to the basket as it turns in relation to the tub seal. Everything is extremely tight and there is no off-balance rotation of any kind that is indicated by the pulley or the tub or anything at all. I have completely dissected each unit and inspected 4 missing bolts possibly missing weights and I have full function of the ball bearing balance rings in the GE and there are none in the duet model, the counterbalance, concrete weights are unbroken and completely intact as well as secured to the tubs, the tubs are in perfect shape and the suspension dampers mount to them very well as well as to the bottom of the unit. I am testing these on a concrete floor where there is absolutely no favor of give in any four directions at the base. I have also tested for over spinning and overpowering from the motor control boards. There is no a centering or unbalanced performance when looking closely at the spin of the stator drive on the GE or the drive shaft nut behind the duet. As a repair and salesman I am unable to sell these two wonderful units because of this completely mysterious problem. And I'll just add that I have looked at the spider arm on the GE and it looks practically brand-new and straight and perfect the shafts look perfect and wonderful on both the motors test out perfectly. Also I have made sure that the drum baffles are not full of any build up of grime on the insides of them and nothing is broken off of anything anywhere throughout the entire machine. I'm at a complete loss and I have been allowing these units to sit in my shop for months as I would come back at them with a new possible fix. But nothing has worked so far. Any serious suggestions would be great. Lastly the tubs do not indicate any warpage whatsoever. Happy dr. Martin Luther King day everyone!!

Hello,
This issue is one that is more complex to diagnose and should be viewed by a field technician and is not a service of the Appliance Repair Forum
