Dee,
After looking at the online manual of that unit I have determined that you have a
bit of a job on your hands.

The plug that you have in your hand is a proprietary plug and more than likely the
socket it fits into is also damaged and both will need to be replaced.

That plug looks like it comes from the heating element in the distiller.
Now if it was the one that pugs into the wall outlet then it would be a easy fix.

But I do not know how any conductors that are in that plug and how much current
is being carried by that plug.
Judging by the size of the cable it can't be more than 10 amps.

can you take a picture of the socket it is supposed to be plugged into?
