I have had 2 of these for the past couple of months and one of them has been very noisy for quite a while. Gave them a good vinegar dip to clear off all the junk yesterday and the noise seems to be even worse.
I don't mind a bit of noise, but I can hear it in the other room. Even a bit of a rattle would've been fine by me, but I can't stand the high pitched/whistle noise. Any ideas what it could be? Nothing looks broken at least...
E: forgot to mention. I'm using the 'nature' setting (randomized flowrate) for both of them. When it starts ramping up the noise gets very loud. At the lowest flowrate I can't hear the noise.
