[Build up of filament on printer head]

ok I will try this thank you for the advice

 

 

do you know the cause of this and how to prevent it from happening again

 

Probably there's not enough pressure among those 3 components that are vertically in line between the top & bottom plates of your printer head.   If you can reach in with your fingers and spin that aluminum cylinder which sits atop the white plastic coupler, then it's too loose.  The way to tighten it would be to rotate the metal ring that has the visible holes (just below the white plastic coupler).  You'd need to do that after cleaning, and while the nozzle is warm.... maybe 150-170C.  The cylinder should be snug but not really tight.   Too much pressure would deform the white plastic piece.

At first this explanation probably doesn't make sense, because the leak is happening below those 3 parts.    But pressure for the lower joint comes from making those 3 inline parts fit more snugly between the top/bottom plates
