Thank you all for the suggestions. I had thought of that but don't have such thin wire that would be rigid enough to be useful.
I've managed to unblock it now by repeatedly loading and unloading the filament.
I was using the clear filament and have noticed it seems to be more sensitive to a higher temperature than the coloured ones. At the default 220C then the filament seems to burn if there is an extruder jam resulting in a black blob.
Incidentally, is it a simple process to replace the nozzle if need be in the future?

also if you have a medical needle .. that can work great... or a syringe ... or a acupuncture needle !!
then take the print bed right down.. so you have lots of space for your hands.. then heat up the hot end without any PLA loaded in... and carefully slide in your sharp instrument in and out of the nozzle... that will normally get all the little ol gunk out and get you back printer... plus its a thousand times faster than taking your hotend apart and trying to clean the head out that way... :-)
just becareful of your fingers with the hot hotend !!
Ian :-)
