Ultimaker 2 Hot End Cleaning

I need to disassemble my Ultimaker 2's hot end so I can really clean out the nozzle (soak in acetone etc). The "Atomic" method isn't cutting it - I still get a lot of under extrusion and jamming due to gunk in the hot end.

Anyways... I've successfully disassembled the nozzle - removed the side fans via their four screws, unscrewed the collar to free the nozzle block, then removed the probe and heat heads via the long screw on the heater block.

So far so good.

Unfortunately I'm unable to safely reassemble the nozzle block to it's rotating collar. every time i try it goes in at an angle.

So is there some trick to getting the nozzle block back into its collar safely? I feel the screw that goes into the block (that seems to keep the heater and probe in place) might be causing any misalignment. Alternatively is there some gunk blocking things perhaos?

(I also want to order a new nozzle in case I can't clean it well but the damn Ultimaker store is NOT processing orders.)

    ... omissis ...

    I also want to order a new nozzle in case I can't clean it well but the damn Ultimaker store is NOT processing orders.

     

    Why do you say "Ultimaker store is NOT processing orders" ?

    I just received today ... 10 days after the order/PayPal payment ... a bag of spare parts that I ordered: Bowden tube, ...

    So ... it is true that they are quite slow processing orders, but ... soon or late ... if you enter the order ... you receive your goods :)

    The ordering processing website seems currently to be broken. I've tried multiple times to order the spare part I need and the processing site would not let me continue.

    It's broken.
