Do any of you know how to disassemble the Jebao MDP DC Pumps?
I have the model rated for 8000 liters per hour, but all of them are basically the same

I basically woke up at 4 am this morning to my siphon-break in the pipe from my return pump to the display tank because the pump "failed" with err04.
Online searches seem to indicate that this means that the impeller is stuck.

I tried moving the rotor/ impeller but oh man, it's stuck pretty good. I see lots of limescale so I'm pretty sure that's the reason.

Anyways, I gave a acid bath but it isn't as fast as I want it to be. So, I was wondering, how could I disassemble this thing so I can access the impeller and scrub it down / better expose it to the acid bath?


Basically the pinwheel, the purplish / pink thing connected to the impeller, has lots of limescale, and so does the impeller, which I'm pretty convinced is the issue.
But the plastic transparent covering doesn't come off (or idk how to get it off).
There are no screws either.

The purplish base does come off, but it's just a stand for anti-vibration purposes.

The white plastic covering in the front comes off just by unscrewing it.
