Stack when vibrating - HP Compaq nc6120 Notebook

look the really heavy duty floor pads used in horse stables very dense and thicker than anti vib because even it restacked extra weight wont stop the vibration

Make sure they have the same bluetooth stack, or at least a compatible stack.
To understand what it means, before you look up what stacks your devices have, look here:
Bluetooth stack

Assuming that you've installed the stack kit according to instructions, you should check the following:
1. The dryer should be securely attached to the washer and not wiggle or move. The washer must always go on the bottom of the stack.
2. Washer should be level and have all four level legs making solid contact with the floor, no wobbling.
3. Make sure the drain hose is not pinched or restricted (or there is not debris in the drain pump) as a slow pump out will accentuate vibration problems.
4. Make certain you've removed all of the washer packing bolts before using the machine (see owners manual for description.)
5. The floor must be solid with no "springy" or "spongy" feel. No matter what you do to the laundry set it will vibrate on a less than solid floor. This occurs on upstairs installations or other wooden floors, especially in an older home. Sometime the floor can be braced to stiffen it. Also, vibration pads are sold that might help minimize the vibration. The walking is a symptom of vibration.

Experience shows that most problems of this sort result from incorrect installation and/or flooring issues, not the laundry. You should not attach it to the wall. It is possible the washer has a problem in which case a technician would need to check the unit. They can check the suspension and drive system for proper operation.

A paper jogger is a machine that has a bunch of little motors inside it that spin really fast causing the bin where the paper is to vibrate. The vibrations combined with the force of gravity causes the pages to line up in the squared off corner of the bin. When the paper squares off it make a nice clean stack like when you first open a package of printer paper.

I wouldn't. Not without a proper shelf for the washer.

Washing machines are heavy because there's a huge lump of concrete placed over the drum to dampen down any vibrations. A tumble dryer is hollow, has little structural strength.

Put the machine on top of the dryer, you're going to get a crushed dryer if not a crushed foot, leg or child. Please be very careful.

Hello, welcome to FixYa.

I understand you have a problem with your stacked washer & dryer, thank you for providing the model number (of both) that is a good start... however I need to follow that up with a couple of questions.

Are these "new to you" machines or have you had them prior to this and just never stacked ?

Also had you run the washer before they where stacked and not noticed an vibrations violently/noise like a hammer spinning inside?

Finally, what method did you use to fasten the dryer to the top of the washer and did you remove the cabinet top of the washer before stacking...for the record it should not be removed as was the case with some other manufactured machines.

Let me know if you can add anything further along with the make & model. I will wait for your reply to move forward.

Thank you for choosing FixYa.

you could have a bad balance ring or if the machine is on a floor that is not very sturdy it could cause the machine to vibrate or "walk". if the tub is loose it may need to be tightened which usually isnt the case. most vibration i notice is from the floor or the machine not being level.

I have ordered KE shake away pads. I'll have to see how they work.

possible the bearings are going. place yor hand in the bottom of the drum and run the drum around and feel the bearings for any wear/ noise/vibration. alteratively the bearings in the motor could have gone and spinning with the belt removed would prove this.

check to make sure the machine is properly balanced. an off balance machine will vibrate causing that sound.
