First locate the capacitor - take the cover off the back very probably.
Next look on Google and select Images - enter Start Run Capacitor to see what they look like - then find you machine's capacitor.
Then take a picture of it so you can tell how to wire the replacement correctly.
Then take it from the machine and read the specification.
1) Farads - microfarads written as uF
2) Voltage - the maximum rated voltage - no problem if the new one has a higher voltage
Then use Amazon to buy a new one.
Good Luck..., September 2016
