I have a 520m Karcher pressure washer and the water is coming out of the handle. I am a single lady, could I repair it myself?

I think I need to replace trigger gun on my Karcher 520 MH, as the water keeps coming out of the end of the hose, at the gun connection end. What do you think?

Also, if I need to replace the gun, my existing part number is 4.775-400.0. What do I replace it with? Are there new compatible models out now?
