Jobo ATL-1000 water bath problem
I'm using an ATL-1000 which hasn't seen much use in a while. On the B&W program, the water bath never fills, and the processing begins immediately. I've confirmed that it works as expected for E6 processing, filling the bath, heating the water and running the recirculation pump.
The manual says the unit won't try and fill the bath for B&W if the developer is over 24C, but I've verified that the developer is well under that (I tested with 19C water).
One possibility is that the unit is not reading the temperature of the developer correctly and thinking it's over 24C. Does that sound reasonable?
Any suggestions on troubleshooting this?
