Jobo cpp-2 processor problem

[gdi]

I just bought a used CPP-2 processor and everything seems to work properly

except it will not heat the water.

 

I tried resetting the overload switch and I think I did but I can't be sure. The

reset seems to be on the left end of the machine and accessible via a hole in

the housing. These is a little silver metal slide switch I believe that will

slide toward the back of the machine and stays there.

 

I have no manual and have been using the resources on the Jobo site. That info

seems to indicate that the reset is on the back of the machine and is a white

button. I suppose I have an old model of the CPP-2 and the switch design has

changed.

 

Is anyone familiar with the CPP-2 and the reset switch? Is yours on the side or

back of the unit? Any tips for me which may confirm whether I need a new heating

element or not, (like how to test it?)

 

thanks!

Does the water pump and rotation motor run ok?

How about the temperature display; is is stable, or do the numbers jump all over the place?

It may be nothing more than a blown fuse, or it could be the heating element itself, or one of the PC boards. Download the manual from www.jobousadarkroom.com and read through the troubleshooting section. Information about the fuses is there. Hopefully, it's not a pc board, they're VERY expensive.

Thanks David - I did resolve the problem, the reset switch had become dislocated during shipping. I took the cover off and repositioned it and it is fine now.

That's good to hear! I'm glad it wasn't anything serious.
