Jebao WP-25 not working...very low flow

[reefer_madness_01]

I have a Jebao WP-25 that is about 6 months old that I had in my frag tank that I took down. I moved it to my brute can for mixing saltwater for my main tank and noticed the flow is WAAAY lower now. It didn't really have any coraline algae build up but read that maybe a vinegar bath would help but it didn't. It is pretty much clean and spotless and still has low flow. All the setting seem to be working but it just doesn't pump much water. I read somewhere that the controller can be "reset" somehow but I can't find instructions anywhere. Does anyone have any ideas to get it working again?
Thanks in advance!

Did you take it apart when you soaked it in the vinegar? If you didn't you could still have some buildup of something hung up in there. Just a suggestion.

Take a toothbrush and remove the impeller just scrub inside where the impeller goes and scrub the magnet on the impeller. Basically get any thin film algae off from in between the magnets.
