DeLonghi ECZ351: Loose unit nozzle

Hello,

the unit nozzle (photo, No. 9) of the firing unit was dripping. So I tried to disassemble it, but even after many turns it would not come loose: because the whole filter, including the gasket, was also spinning.
I finally managed to hold the filter with pliers and loosen the fixing screw. Now the filter and gasket have been removed.

But: the nozzle of the assembly does not come out, the edge turns with it. (see photo)

Is there any way to repair it without disassembling and opening the boiler?
