These machines seem to be all over all of a sudden. Maybe they always have been on AW? There was/is an Avocado machine in Detroit, and Lawrence's machine in Atlanta. I just got a white one recently, and have had the Coppertone machine since this summer.
Here's what I do Jim when I first get a machine:
1) Plug it in and turn the timer to a spin cycle. With the lid UP so it won't spin, turn the machine on. Listen for a quiet idle. I have had a few machines not pass this first step, but most do. If the transmission idles OK, the pump turns, the basket drive pulley is smooth, etc. you'll know it now.
2) Put the machine in spin. This is a good test for the belt, the bearings, etc.
3) If both the above pass, then you may as well put some water in it (for a low level wash) and see what you get. At that point take the service panel off the machine, and look for leaks on the floor underneath the triple dispenser, the pump (opposite side of the machine) and for water coming between the tub and the baseplate.
Sometimes there are tell-tale signs of leakage in machines that I see on their baseplates. If I see these, I will pull the basket and tub and correct those before bothering to put water in them, but in your case I'd just fill the machine and see what happens.
If you have any questions about any of the steps above Jim, let me know - I'll be happy to help or walk you through anything that I can.
