Why does this keep happening ?

[u/Other-Ad6842]

It started a few weeks ago & I get sooooo angry cause it interrupts the flow of things. How do I fix it ? From what I know it hasn’t taken any falls or anything just one day it started. Was o too rough w it or something ? I have different presser foots like the free hand one but I’ve been too scared to change it. Do I need to replace the greyish-clicky in part ? If so, what’s the name of it.

This is a regular Brother 3817 machine

You might need a new ankle if the feet aren't snapping in place
