Hi all,

It's been a while since I've last posted here. Hope y'all been well.

Recently my Jobo CPP2 started acting up. The motor was getting sticky, struggling on reverse rotation. This I was able to remedy by replacing the motor with a spare I had lying around. The thermostat is whack, but that can be compensated using a thermometer.

The big issue is the pump. One day it just stopped pumping the water. I took it apart and manually rotated the impeller, after which it was rotating fine, albeit with a ton of noise. I put it back, processed some film, but the next time I fired it up, it was not pumping again. I took it apart, put some WD40 through it, and it was rotating fine again, this time with a little less noise. Processed some film. And the next time I fired it up, it's not pumping again. Electricity is being supplied, as I hear a hum when I turn the pump ON.

Anyway, I think I need to do a serious repair of the pump, but I don't see an obvious way of taking apart the pump unit. Long story short, does anyone have any resources on servicing the CPP2 pump?

Thanks!!
