Recently opened up a 120v,60hz Coffee machine, and the pump has a large
diode in series with one of its 120v input leads. The pump works either with
this diode, or without. Just wondering why its there?

Thanks

Are you certain it's a diode and not a fusing device? My coffee machine
had two of the latter in series with the heating element.

Yes sounds like a PTC fuse or similar.
