how do u clean your jebao dcp pumps?

[marysea]

have 4 jebao DCP pumps--two 13000, one 18000 and one 2000. each time i clean one very well in vinegar for a couple of days, rinse well, dry completely, test, then put away for about 6 months. BUT when i go to use one, i get an error message E04--stuck impeller. what gives? anyone have the same problem? how do u fix??

Do you take it all apart and wait until everything is completely dry before re-assembling?

Some pumps use certain plastics in them that don't react well to vinegar. Jebao may be one of them.

what do u recommend using instead of vinegar?
guess the pumps should be used until they stop working and then throw them away.

Buy a 5lb bag of citric acid from Amazon. Use about 1 cup per gallon of water to mix a soaking solution. Soak overnight or even a day or two. I've soaked until a layer of mold went across the surface....probably not recommended.
Brush off well while rinsing. Be sure to disassemble and clean all moving parts.
Great sticky above on vinegar the great pump killer or some such, and it is. I've lost some pretty expensive plastic covered pump magnets to soaking in vinegar.

do you use any lubricant on the inside of the pump?

I agree that citric acid is better than vinegar. I don't use any lubricant on a DCP6500, the ceramic bearings don't need it.

The only thing I can suggest is that you have a build up on the ceramic shaft or bearings. On mine the impeller turns very freely with no hint of friction/grinding.

Use citric acid.

I use a denture brush to clean my jebao pumps, once a year. no chemicals. take about 20 minutes
