240° is waaaay too hot for PLA. It likes something like 180° or so I think ....?

Yep, you said it Bill.. I am yet to see PLA that takes that sort of heat. When you heat PLA up to that extent you have very wierd issues...

The heats travels up the filament and makes like a meter go chunky and unusable. That excessive heat has also most likely blocked the nozzle as the PLA got cooked in there. You will need some ABS to flush that out (or plastic that likes high temps) if you don't want to mess with the nozzle.

1. Set your filament diameter in Replicator G to 1.80mm
2. Cut off a good meter of that PLA, or at least back to the roll.
3. Try to load it again at 200c.
4. If you can, load ABS or something else through that has different properties, you want to melt the blockage and that's hard unless you have plastic that melts at a higher level and can mush up the bad stuff and push it out.
