Re: Jobo CPP2 not heating
I'd double check all the electrical contacts. Years ago had intermittent heating problems with a processor. All the electrical contacts visually looked to be fine, but one of them was not. Cleaned it up and the intermittent problem disappeared.
Re: Jobo CPP2 not heating
If you can’t seem to get it to work, pop a sous vide immersion cooker in one of the bottle slots. Cheap, easily found/sourced, and can be dedicated solely to keeping your processor at temperature :)
Re: Jobo CPP2 not heating
Thanks for the replies, I’ll try the first suggestion and if that doesn’t work go for the second, great tips!
Thanks.
Re: Jobo CPP2 not heating
If you run hot tap water over the thermal switch it will pop. I popped mine with maybe 125-130 F tap water. I use a toothpick or a small tool to fully depress, gently, that little breaker to get it reset. I've never fiddled with the breaker, not sure about contact cleaner. I would be gentle, maybe start by gentle cleaning with a toothpick or Qtip and a drop of alcohol (not with any added glycerin etc) I have a small bottle of ancient Kodak movie film cleaner, cfc113 and heptane. Tremendous solvent /cleaner also banned.

Thanks for the information, just so I’m clear, should I remove the thermal switch from the machine before running it under a hot tap? Or does it only function if the machine is powered up? I’m hoping the former!
Thanks.
Re: Jobo CPP2 not heating
Just to update, I changed the fuse and put contact spray on the connectors. The thermal cutoff switch was moving freely so I left it alone. After putting it back together it is very slowly getting up to temperature but it’s really too slow, it’s taken 3 hours to rise 3*C
Does anyone know if there’s a way to speed up the heater element?!
I suppose if it maintains a temperature of say 38*C then it would be fine, just a case of mixing the water as close as possible prior to processing. It would be a pain though if I have b&w and then colour to process as I’d need to dump the 20*C temp water for fresh hotter water.
Any info on the heater would be great, thanks.
Re: Jobo CPP2 not heating
I'd also take a look at the heating element and see if it might be covered in calcium. no idea if this would be a cause for really slow heating though. If you need to heat things up quickly, I'd just add hot water to the reservoir.

Call Omer Hecht @ CatLABS. He's official service for Jobo. There's several things that it could be. The heater connections could be dirty, the heater could be defective, etc. He takes older units on trade :rolleyes:

Thanks for the tip, I’m based in the U.K. but hopefully I could get some advice from him at least.
