You should post your message on the Gardenweb's Laundry Forum, where you'll get lots of responses. While it's simplistic to say this, have you checked that the machines are level? Out-of-level is the most common reason for washer/dryer excess vibration. The appliances will have adjustable screw-in feet underneath to bring them level. You can check whether the machines are level with a bubble level found at any hardware store or Home Depot. Also, putting down plywood under washers is fairly common, and not a big deal, but I don't know that you'd need to cut out the laminate flooring. You can put down the plywood over the flooring, check that the plywood is level and correct where it is not level by inserting shims, then put back the washer and dryer, readjusting the screw-in feet to again keep them level.

my thought is the laminate is a little too slick to hold the machine in place. Could you try putting some non slip type cushion under? Even the thicker rubber pad used as laminate pad may work, or the non slip padding used under area rugs. It would be a simple fix if it works.

... after her whirlpool has started acting up.Started acting up how? What is the model # of the machine? It may be reasonable to repair rather than replace.

Oh, this is a fun one. Can anyone tell me how to link my excel spreadsheet? Or share it? (I haven't been on here in a long time, sorry) Where I live we have long winters, so I use the cold chilly nights to catalog purchases I overlooked, but almost everything! I keep my camera handy, my laptop and once you start doing this I swear you will be obsessed. Take pics, general pics, immediately put them on the computer. Don't wait because it gets overwhelming. Create a photograph folder for each room in your house. Add photographs of each room with general description. Because it can be overwhelming, first take general pics of your living room, dining room, kitchen, etc. And you really should catalog everything. I have a large 3-ring binder with sheet protectors. I keep a photocopy of my receipts in here. Anything major of value that you purchase keep in here. Washers, dryers, artwork, appliances, etc. Keep the warranties in here along with receipts. Great when you need to have something repaired. I keep a disk with photograph details, original receipts in my husband's office as my backup. Why you should do this: for example, if there is a fire, flood or major damage in your home, you can't make an insurance claim by verbally saying I know there was two pearl necklaces and one blue sapphire necklace and two waterford bowls and I bought decorator drapes with the most expensive fabric and the best expensive paint with molding that was $200 sf, and I had 30 Ralph Lauren shirts at full price, etc., You really do have to prove it. We have an old victorian and during a snowstorm our chimneys fell - we had to fight insurance company to prove we wanted historic bricks, custom brickwork pointed a certain way at a certain height and replacement of the fence that the chimney damaged, etc. Anyways, Sometimes that means digging the stuff out of the fire and proving it if it is not recovered (voice of experience) We had photographs and documentation. So this is a fun lifetime project. Once you get it going it's fairly easy. First way to start, starting today every single item you purchase of value, start documenting those items. Years ago I created my own Excel spreadsheet. Because of sheer volume, I purchased a program which is very detailed. My husband is like me, too. For thirty years he has been documenting his items (detailed tool list right down to the values) so combined with the two of us it really called for pics and more organization. I started doing this years ago. Here's my excel spreadsheet which I still keep as a reference. Program I use is called Home Manage by Liberty Street. There is a free trial for it after a xxx amount of days you can no longer access it so don't get carried away playing with it cause you will waste your time if you don't want to pay for it. How do I upload my Excel spreadsheet?
