Question: Does this work on these new front loading washers that have a flat top?
Document: Doesn't really fit my new washer or dryer. I am using it and did get it to work out but I can't put much on it as it is just barely resting on top of the washer. It won't even fit on my dryer.
I'm a short person and can't reach the laundry shelves on the wall way above my washer and dryer. I thought these would be perfect, but boy was I wrong. I have a white toploader washer and front loader dryer, both whirlpools. The shelves didn't fit because the top of the washer and dryer both slope up and back, and the shelves drooped toward the wall, the brackets never touching (even after moving them forward and backward). Nice idea but it doesn't work well in this instance.
This has been a great solution to the problem of things falling behind the washer and dryer. These are very easy to assemble and install. Because they are wire, you can just bend them to get them to fit as needed. We have two: one behind our washer which is flat on the back (the controls are on the front of the machine), and one behind the dryer which has the raised area with the buttons and dials. Both fit fine.
This is really a great idea. Unless your washer thrashes less than mine I would only use this on the dryer. Very adjustable however I think over time the bolts will loosen and the nuts and flat washers disappear into never never land behind the unit making them impossible to recover. Recommend this ship with lock washers which is why I held back a star.
Such a simple device, and I am so happy to have found it. Our laundry area has zero storage, and this simple shelf has solved that problem. Installation was a breeze, and my laundry area stays nice and neat now. We have a top-loading washer with a squared off control panel on the top, as shown in the picture. Will probably not work is the control panel of your washer is rounded.
Good storage for the money! Wish it was a little more sturdy but it's good storage and I already had one for the washer so purchased another for over the dryer. Just make sure that your machine is flat across the top or it will not sit level.
This would have been nice to have years ago when it was produced. With newer washers, the design is dated. I love the idea, and I ended up making it work but not without some extra work myself. I am happy though and wont return it. It is doing what I purchased it to do. I just had to make some modifications.
It was great. Too bad I could not adapt one to my new washer. It has too many curves on the top panel. Make one that adjusts to any type washer and dryer.
Got a new washer with an uneven/rounded lid and narrower sides. I used to be able to keep the soap on top when closed or even on the side when open but now it is impossible either way. My washer is between my stove and a window so there is no other place to put stuff. This works great.
This one is a horrible design. It does not mount on the wall or on the dryer. it just sits on top of the control board (where the knobs are) and puts all of the weight on the control board (which is made to take ZERO POUNDS)  the two strips that you see on the wall behind the dryer is not part of the shelf. Skip this one, or buy one and use it only to have a repair bill for your new dryer.
Answer: The shelf is mounted on top of the control panel of a washer or dryer as seen on the picture.If your appliance doesn't have that top control panel, the shelf will have no support to keep it in place.
