Try a socket as it’ll be less fiddly than a wrench and also has a lot of thermal mass so it won’t get too hot as you loosen the nozzle. I crack it loose with a 1/4" ratchet, then remove the ratchet from the socket and spin the socket and nozzle out by hand. You also don’t need to be super hot, maybe 180C or 190C and you can shut the heater off once it’s cracked loose (then turn it on when threading it back in). Gloves aren’t a bad idea either.
I got a socket just now, but when I unscrewed the nozzle and tried to extrude some filament, the wheel turned but no filament was extruded. I saw a faint strand of unmelted filament in the hole for the nozzle. Here is a video.
You’ll probably want to strip the whole hotend apart and see what the deal is. Without a nozzle, you should be able to just push the filament through by hand (after loosening the tension arm). I wonder if your PTFE tube is bad. Not sure how your extruder is setup, by my direct drive Volcano clone’s filament path is extruder gear > plastic filament guide > PTFE tube > heat break > nozzle. One of those things is bad. Tear it apart and inspect each part for damage and ensure you can easily feed filament through each part.
I apparently need hot gloves, I tried without them but burnt my finger and possibly graunched the spanner.

A socket? I will consider buying one along with gloves, thanks.
Not sure what you call them across the pond:

I’ll have to contact the manafacturers, it shouldn’t be breaking this often when I use it normally.
You can if it’s under warranty but this is pretty typical of the hobby unleas you’re buying a real high-end machine.
Really, having a problem every week? Anyway, it is under warranty for the first year, and it’s been just over a month, so I’m safe.
