Swish is kinda the noise a vacuum pump makes in normal operation.

Does that really mean anything? Is it producing vacuum? If so, how much?

It seems that a failure of the vacuum pump has some mechanical chatter or clicking before failure. I have been doing a lot of reading on this subject as I am about to rebuild mine.
