I think I've blown a fuse from gripping the heat block too tight
I was doing the xyz calibration and it just gives me error, then I check the nozzle to make sure there was no plastic stuck to it. And there was nothing on the nozzle, then I saw plastic coating the where the nozzle met the heat block(?). I've removed the nozzle to cleaned before this (my first problem I ran to right after finished 2nd print). Is it possible that it's because I didn't screw the nozzle it tight enough?
My question is how best should I clean it up?
edit : I've removed the nozzle and cleaned out what I can and I put the nozzle back in and I think I've shorted the whole thing cause I gripped the hot ended too tight. I'm guessing I blew something. Where should I look? I'm so new at this and I really really don't wanna clutter up the forum, but I need help.

➡ if you think you've blown the fuse for the hotend, have a look at f3:

I just pulled the F3 fuse, and yes it is blown ( looked from the underneath and there was only little connection on one side and nothing to the other side, where I'm assuming there should be if it's fine, right?) Can I just go to the store and tell them I need ato 5 amp fuse? or is there something specific I need to tell them?

Fuses for muse. Any power connection should be mechanically firmly tightened, or soldered and aligned correctly! There lies success and little or no issues with power supply.

It's a standard car spade fuse. so a car parts shop would be your best bet. Even the local petrol station may be able to sell you one. Just make sure you get a 5 Amp of the correct physical size.
You probably shorted the extruder heater cables with the pliers.
And yes, it is quite likely that the nozzle wasn't hot tightened after being installed. You need to screw the nozzle in as far as it will go, unscrew half a turn and then tighten up the heat break onto the nozzle. Heat the nozzle to 250 degrees and tighten. For removal you again need to heat to 250 degrees before unscrewing the nozzle, otherwise you could damage the heat block threads.

Yeah, I picked up a few spares 5 amps as well as the 15 amps and it is now on, except I still can't get it calibrate.
