Absolute bubble-level is not a factor in vibration. Weight just needs to be equally supported on all four corners. Set the machine into position and adjust one of the front corners while it's spinning to minimize the vibration.

However, you won't fully solve the vibration and transmission there-of if the floor isn't sturdy and stable enough to dampen it.

Your floor looks like it is laminate or perhaps it is hardwood-but I bet it is on a sub-floor with no concrete under it at all to separate you from the unit below you. Dadoes can comment about long term effects, i.e. potential structure damage of any kind, but you may have to work out an agreement with the people below you about when you will run your machine.

Thanks... yeah this thing is powerful. can i put it on bricks or something like that you think? Yeah there is no concrete. Well i found out how to get it to spin on "low" at the end of quick wash cycle which is only 5 minutes.. May end up with that like 2 times a week.. 5 minutes, twice a week... still long term effects do you think.... Dadoes?

Armjim. Yes its to code. Its in the kitchen. I just have the drain pipe like that right now until i can get a proper drain extension.

How do you figure placing it on bricks will help? The vibrational forces will still go into the floor. Some sort of rubber mat may help to a point but any residual vibration, again, has nowhere to go but into the floor.

There's no risk of damage to the machine. Potential for structural damage to the building depends on how much you can minimize it. You could also be at risk of getting in trouble for having the machine from a landlord or condominium board if neighbor complaints continue or escalate. Does anyone else in the building have washers in their apartments?

History: 1949-ish into the 1950s, there was a toploader called the Economat produced by the Bendix brand. It had a rubber tub and didn't spin. The drain pump also functioned as a vacuum pump, which sucked air out of the tub (the lid sealed air-tight) and made the tub collapse to squeeze the clothes around the agitator for extracting the water. It was popular in multi-story apartments at the time and avoided the problem of spin vibration. (Bendix marketed the first automatic washer on the US market in 1937, a frontloader.)

Were the shipping bolts removed from the back?

The very first washer I ever bought was a front loader, delivered and installed by the store - and yep, they didn't remove the shipping bolts so the first time I tried to use it I thought it would shake itself or the house to pieces!

If that isn't the problem, try some carpet padding (maybe a double layer), or thick rubber tile (like you can get for home gyms, under play equipment, or stair tread).

Might be a good idea also to get one of those trays meant to go under washers, to stop a leak from flooding the unit below you.

With the bricks... dunno, guess i just thought since cement slabs are used a lot under washers...? Well, this machine is pretty advanced. I found I can do laundry on 'no spin" .. it just takes 2 hours to dry... OR there is low spin. I only anticipate using it like twice a week and the spin lasts a few minutes...What about centrifuges? A lot of laboratories have those and they are WAY more powerful. I wonder if there is code that those must be installed on cement? Yes the shipping bolts were removed and im thinking about getting one of those gym mats for sure. Im not really worried about flooding. For one im not doing wash when im not here and it really only spits out about a gallon of water with each load. One other person has a washer, but its one of the portable ones you stick in your bathtub. its top load and you can open it while its spin its so minimal.

I've had my washer in my apartment when I moved in. That lasted for one cycle because I had to sit on it during the spin... I didn't try any other locations, as I have laminate flooring throughout. I did try the plywood and it didn't help. Granted, it probably wasn't thick enough and I certainly didn't want to screw it to the floor like one is supposed to. The washer is in another room now with solid flooring.

Am not a fan of these rubber mats. There's a video on YouTube where a washer runs perfectly fine on concrete and then starts to vibrate when placed on the rubber "anti vibration" mat. Gets even scarier with a dryer on top.

A spin dryer would certainly work because - like a top load washer - it doesn't vibrate up and down but sideways. I have one (6 lbs., 2,800 rpm) and it doesn't shake anything. Not even the machine itself, as it spins so fast (if loaded correctly, but that's common sense).

yeah space is an issue. I have a small bedroom and living room other than what is picture. i think ill be ok since i found no spin and low spin options AND my downstairs neighbor is very cool.

Heather what sort of laundry are you doing that dries in a couple of hours after not being spun or spun at low speed? For years I used FLs and my experience is that even on high speed spin if I left a load of towels in the washer for two hours afterwards, they would not have been dry.

Heather Wildcat, is your LG a washer/dryer combo unit that performs both functions? Or do you hang-dry?
