There are two possible causes for this:
- A grinding noise is caused when the stainless steel skirt is loose. To fix this just push the stainless skirt up into the guide groove and turn to the right until you hear a click. With the skirt secure, the noise will go away.
- If that didn’t fix it, the grinding noise might also be due to a slightly bent stirring shaft. If this is the case, unscrew the clear plastic end cap on the bottom of the device and gently push the impeller until it is centered.
We non-engineers have no idea what a "skirt," "guide groove," "stirring shaft," "pump disk," or "impeller" are. For heaven's sake, we can only guess what you're saying here. A diagram, or at least some definitions, would make it possible for us to stop this awful grinding noise I now always experience when using your appliance.
Hi Richard! May I ask if you have a copy of the manual? If you provide an email address I would be happy to send a PDF version over to you, or you can email support@anovaculinary.com and request a PDF copy. It has labeled diagrams that might make it easier to identify what is being suggested.
On my unit the stainless steel skirt fit is loose even when pushed up and turned firmly. The skirt will rock side to side with little force. I fiddle with it and can usually find a position where the stirrer does not contact it but it is getting worse over time and I fear eventually it will be so loose that it may drift around during use which will make unattended cooking cycles impossible.
Same problem here. The issue is the plastic guide rails the metal cylinder turns onto wear over time (a very short time at that) and quickly it has enough play that it hits the spinning impeller all the time once water starts pushing it around. It's quite annoying, a metal guide railing system would have solved this issue.
As Vaughan mentions, the wear was pretty fast - my unit is not that old. I use it maybe once per week on average. I haven't looked yet - does anyone know if the plastic part is replaceable?
And, related, will the new product (Precision Cooker) have the same problem? I was thinking of buying a few of those for gifts but I don't want to do so if it only lasts a year before needing repair or replacement.
I am having the same problem with the new unit - I only used it a few times and the most recent time I used it the shaft just fell down during use - I am hoping that my unit is faulty and that a replacement will not have this issue. I can't imagine how such a design flaw would have made it through testing.
I have the same issue. I've used the Anova Precision all of 6 times and the steel skirt is very, very loose even when 'locked' into place. I actually put a permanent marker mark on the skirt so I had the 'right position' to lock it in after the 2nd time I used it. And now that mark no longer avoids the metal on metal grind. Seriously, if the skirt had been 1/8 an inch shorter, this could all have been avoided.
Took a hammer (yes, a hammer) and hit the end of the heating element to bend it away from the stirring shaft that was rubbing against it. Reassembled and VOILÀ!!! Problem neutralized. I know I probably voided my warranty, but the grinding has stopped.
Skirt doesn't click locked, it's quite wobbly
Skirt doesn't click locked, it's quite wobbly
Plastic ring that mounts the skirt looks to be deformed from heat. Skirt won't lock, making the whole immersion element wobbly. The impeller shaft seems to be seated ok. If I rock the unit inside the skirt I can find a quieter spot, but the noise doesn't go away.
Followed your suggestions, wiggled the propeller shaft to ensure it was in the middle and it worked beautifully 🙌🏻 Thank you!
I took the skirt off, then re assembled. I felt the nice click. Turned the unit back on, and it worked!
