Do your airwashers make clicking noises? I had one that did, but was kind of old and beat up. I bought a new one and, sure enough, like 2 months later the clicking was back.

I’ve tried replacing the... little walking thing that moves the discs? (not sure what to call it) that makes the noise but it didn’t help.

I had this issue too at one point. I ended up soaking that part in vinegar (to remove the gunk on it) and then rinsing it off with water, which ended up fixing it. I assume it was just grinding due to mineral build up. Seems like it's a pretty common issue, as it's even listed on their website in the FAQ.

Okay I could’ve sworn I scoured their website for this information. Granted it was a few years ago so maybe it’s new...? I’d found the “push the rubber coupling” tip, which has helped before, but I am breaking out the vinegar as we speak - thank you! I owe you one.
