Jebao DCP rotor repair

[Pny]

Just wanted to share some photos from my Jebao DCP5000 rotor repair, success story. Pump say error 04, ie: "rotor stuck", and indeed the rotor was stuck! The ceramic bushings that holds the plate on the rotor was cemented to the rotor shaft. Even after 10 hours of vinegar bath, the parts was as glued together...

Above: Loosen the bushings using a small screwdriver.

I first removed the shovel wheel and the black plastic plate. I did this with a large screwdriver. Then I separated two bushings by putting a very small screwdriver into the holes and carefully rotate it. After that I took a polygrip and rotate it until it came loose...

After another vinegar bath, the parts was ready to be reassembled again.

- Saved myself the trouble of buying a new rotor!

Do those pumps calcify quite easily?

Do those pumps calcify quite easily?

I might be dosing my alkalinity a little too close to the pump... (?)

Bumping an old thread. I purchased a new DCP8000 to replace one with this very problem. Finally got around to repairing the replacement and the rotor was stuck. Getting the impeller wheel off was most difficult in my case. Once removed I loosened the bushing with ease. I wonder if I disassembly is required, perhaps loosen the bushing can be accomplished without disassembly?

Thanks OP!
