Not sure of the original post on this, but I just got a Spectra 11 and it is incredibly loud! It seems that some of the noise comes from vibtation of the plastic casing. If I lightly press down on the motor housing a lot of the noise diminishes. I managed to slip some business cards under the housing cover to cut the noise down.
Has anyone done any creative adaptations to insulate the plastic parts? I've been thinking of using some electrical tape as gasketing for the cover and between the body top & bottom (but I'm afraid to avoid the warranty)!

First, if this is a new machine it should not be making that much noise. 2nd, if it is a new machine this is totally covered under warranty and you shouldn't be doing any modifications to it. Contact the seller and get it fixed or have them send a replacement.

Well, I guess that is an option. I was just wondering what others have experienced as far as excessive noise on a machine that is loud when running normally, and what may have been done to alleviate the problem. Thanks, Jim B.

Sorry if I seemed short, I did not intend to be.
I'm just concerned that if it is a new melange, then it should not be that loud. Heck, even if used for a year it shouldn't be all that loud. I mean they are not inherently quiet but they should not be so loud it is uncomfortable.

Have you checked to make sure all the screws are tight? Like Chip says, a new grinder shouldn't make a lot of noise from loose parts. It may also be worth opening it up and making sure everything is tight on the inside.

Hi Ben, That's kind of what I was thinking, but I didn't want to do anything that might void the warranty. I'm still thinking that something to insulate the plastic parts from each other (like a strip of electrical tape) would help in any event.

If something's loose, it could easily escalate into a larger issue. I'd recommend figuring out what the root cause is.

That's a really good thought, Ben. I think I will open it up, then, and check things out. I've got about 3 hours left on this batch and then we'll see!

Follow up... I tried to open the case, but it was not as easy as the photos on the "Changing the Melanger Motor & Maintenance" page of the alchemy site. I guess the newer models with the central shaft have a different way of being disassembled. Any help on that? Looks like I might need a special tool to release the shaft. All that being said, I'm pretty certain that it's the plastic case making all the excessive noise.

You need to take the black ring off the shaft. It just pulls off with a little effort. You can then undo all the screws and take the bottom off

Hi Mark, That did the trick! I wasn't sure when I first read that - I thought that the white cone-shaped bushing would have to come off first. What I hadn't noticed was that the black part was more than one piece. With the ring off, the rest was easy. Everything seemed tight, but there are a lot of places where the plastic can rub with the normal vibrations from the motor and grinding wheels. In the morning, I'll see about trying to insulate the plastic with some electrical tape.
Thanks, everyone, for the help! I'll let you know if this works.

Following up... Following Mark's instructions I was able to open the cover. The screws for the motor housing were tight but there were some alignment tabs on the housing that might have been rubbing against the cover, so I removed the screws for the housing so that I could add some electrical tape as an insulator. Surprise! There are rubber washers between the housing and the cover - presumably to act as standoffs and insulation. Unfortunately, they were so compressed that the plastic parts were in contact with each other anyway causing all the noise! I wrapped the edges of the housing with the rubber tape and replaced the motor housing on the cover, taking care not to overtighten the screws! Once it was all reassembled I plugged it in and turned it on and it was MUCH quieter. I suspect that if I did the same thing with the main body and cover (this time properly tightening the screws) that it would be even a bit less noisy. So, thanks to you all; mission accomplished!

Good to hear it worked for you Jim. As you'll have seen after dissembling, it's really a very simple piece of machinery, so you'll mostly be able to find and fix any issues quite easily. Ours have been going strong for years without any major issues.

Jim B Good to know all of this. Yeah, I really enjoy mine but it definitely roars along unless you feel it pretty full of chocolate/etc. At least 2.5 lb. Update: did the same, open the outer housing and remove the screws that cover the white plastic motor cover from the white base. Covered all overlapping plastic tabs and added thickness to the rubber washers on those screws using some very short donut-shaped loops of heat shrink tubing. The entire unit seems much quieter.
