This is a good washer, and basically the only one that would fit my 26" space. (One more inch and I could have gotten a 27" model!) I've had it a week now, and have done half a dozen washes.
During the agitation cycle very early in the washer's run (right after the washer drum fills with water), it makes this fairly loud grinding noise - back and forth, back and forth. I've never heard any washer make that sound, ever. Fortunately, this is a normal sound that the washer is supposed to make.
How do I know this is normal? This website has a page where you can listen to the various sounds that the washer is supposed to make. There is a QR code to scan in with the registration/owner's manual that takes you right to that page. And yup, it sounds just like the video they've posted. I was relieved to find out that there was nothing wrong with my washer.
Unfortunately, this grinding sound is very jarring. Other agitation cycles I've heard during my entire life sound a lot smoother than this so that they just become sort of background noise, white noise. When the washer starts it's agitation cycle, you definitely know it. What is interesting is that GE was so aware of this being a weird sound that they put it on their webpage . . . instead of working on a solution to make the sound less annoying.
This stacked unit is a replacement for an older GE stacked unit I had; about 15-20 years old, I would think. The washer failed - it wouldn't drain, and repairs would have cost about 25% of the cost of getting a new one, so it was time. What I also find It interesting is that my older GE stacked unit didn't make this annoying agitation noise.
The dryer works just fine. One nice improvement they've made from my older unit to this one is that they've increased the amount of drying time. My old one would only dry for 50 minutes, which was never enough. The new one can be set for up to 90 minutes, which is enough. Also, the old one made this very loud and annoying mechanical buzz - EHNNNNNNNNNT - when it was done. This one doesn't make any noise when it's complete.
This annoying agitation cycle grinding is the only reason I have dinged my rating from 5 stars down to 4. If you're going to place your washer/dryer in a location where you can't hear it, this is not a problem at all, and I would rate the W/D the full 5 stars.
The "writing a review guidelines" say I shouldn't mention store names or cost. Staying within those guidelines, I'll simply say that this product is available online for significantly less than the amount shown at this GE website.
