Bespoke AI Combo All-in-One Shaking

We also initially had this issue with our new Samsung Bespoke AI All-in-One Vented Combo washer and dryer: thought it was a counter weight issue or manufacture defect in the drum which was noted as two possible issues.  What ended up working for us was the following:

after checking the obvious - no shipping bolts (4), saw Samsung Rep say 4 or 5….not sure where a 5th one would be, unit came with a separate install sheet that notes and diagrams only 4 shipping bolts.  Also, we use a matching pedestal and ensured it was locked into this as well.  Maybe the pedestal contributes to more vibration due to the center of gravity being higher (?), do not know because ours is only on a pedestal.
My solution:  I made sure unit had zero rocking, pushing on sides and it should not shake at all….showing that all four corners are level on the floor.  Ours is on a second story laundry room on a tile floor. Next once unit is firmly on the floor, I used a wood block (2” X 6”), tilted the unit up in front and slid the 2” block in the middle far enough in to pass the edge of the pedestal front edge and where it can support the unit and hold it off the ground in front 2”.  This provides free access to the pedestal feet. I could not get the rear feet to move, believe the rear (L&R) feet are stationary, but the two front (L&R) feet to turn to raise and lower them.  
so what I did was to make sure both front feet were all the way up (counter clockwise), and then I marked with a sharpie a black line on the very front of both L&R feet….this was key, then I rotated (clockwise) down the feet exactly 10 full rotations - both Feet (L&R), so they are calibrated exactly to one another.  This will cause your whole machine to be slightly higher in front but should keep and or make the unit exactly level in front from left to right. 
Next once both front feet are equally set to 10 rotations (yours may differ), I very carefully tiled the unit upward toward the rear to remove the 2x6 propping it up, and carefully set it down, making sure I did not disturb those two front L&R Feet, I just calibrated to 10 full turns.

Next, I went into settings and washer settings and selected both diagnostics and ran that, also mainly “Calibration” setting which seems to focus on calibrating the counter weights to the units current position.  This seemed to be key.  From this point on we had a very  significant reduction of vibration and mostly none.   When the unit starts to spin on highest setting and slows down we may get a temp vibration but now once in a while and that can now just be due to load balance.  This truly has fully addressed and solved our problem.  Now 10 full rotations of both L&R front pedestal feet worked for us, you may need to see which works for you.  From time to time I check the unit simply by grabbing it with both hands and seeing if and where I can shake or rock the unit.  I have had no movement since I tried the steps noted here, but if I had, I would simply use that block of wood, check those feet again and maybe try some small adjustments (1/4 Turn of one or both from feet?   Best of Luck.  Samsung Technical Support only address some of the reasons for this issue.  Here is a real solution from a real long term Samsung Customer.  

We are having the same issues. we have to be very carful on what we load. I'm about ready to bolt this thing to the floor! Seems like this last update made it worse too. not sure. 

Any Updates to this ?   I have only done 3 small loads &  the same problem occurs and it occurs during the rinse cycle, but mine will actually get an error code then I have to remove all the clothes.  Then I have to turn off the power and then power back on and  re-calibrate and  try it again.   Last load it kept failing on Rinse cycle, so I just went to the spin cycle (which seems even faster spinning) but it didn't get an error code.

Maybe like others have , its due to the extra height and "flimsiness" of the very expensive custom Samsung pedestal that we bought to put under the All in one Washer and Dryer.    Maybe its too flimsy and the extra height causes more imbalances.

Mind you its is extremely level - I even have a digital level and checked again and its les than 0.1 degrees off level ! 

I'm very frustrated after paying so much for an insanely expensive machine I should be able to wash my clothes and not have it get error codes and reset for every single wash ! 

I've had mine for years shakes It shakes the whole 2nd floor, yes its a older house but would never of gotten it if I would of known it would cause objects on shelves in other rooms to fall off. Even things on top of a heavy fridge not attached to any walls will occasionally fall. I don't have the pedestal for it actually found this post by accident when googling if getting the pedestal would help with the shaking. Its so bad and drives me crazy since I cant store anything on top of it. Id like to be able to keep my laundry baskets or oxiclean on it with them eventually falling but it doesn't matter how small or large, light or heavy they all fall in the end. I even bought a small heavy duty magnetic shelf with a 60lb weight limit stuck it to the front of the washer just to hold a small  box of dry sheets and a dusting brush I use to clean the lint dryer but it too will randomly fall off every once in a while bc of the shaking. I put ant vibration pads under it a year ago but they have yet to make a difference, at this point they are only still under there bc its not worth the effort it will take to lift the unit again its just too heavy. 

There unit says there isn't anything wrong with it no error codes or messages, all data says its perfect at this point its just something I've been forced to live with needing a ventless dryer option.
