Hey everyone, i heard my DOS kick on for its nightly automatic water change and one of the pumps was making a wicked noise, i can find people on youtube that have had the same issue, but i cant find any threads or resolutions as to what the problem actually is. The motor attempts to spin but just rattles and makes a loud noise instead.
Heres a link to a video of a DOS on youtube with the same exact issue i have.
