If I read you correctly, you added new machines to a farm of older machines and they all are going crackers in the same fashion?? Mine did just as you described and it was the power supply, on a brand new machine. No problems now after replacing it. But, in your case again if I'm reading you correctly, all machines now are having a similar problem. It just might be the room circuit is overloaded. Drag several extension drop cords from nearby rooms, on a different circuit, and see what happens when you plug the new machines to another source of juice. If this seems to do the trick, then remove the front of your electrical panel where all the circuit breakers are, identify the wire from that room and get an amp-probe to read just how many amps you're pulling on that circuit. Look for corrosion while you're at it, clean the leads to the breakers, your white common and the ground wire. Check the main L1 and L2 leads to your box (those two really BIG wires at the top) and make sure that the load (running amperage) is balanced between the two. Kick on the dryer, start the dishwasher, open the door to the fridge, if your stove is electric turn on some burner eyes and the broiler and see what you get when other loads kick in. Sure sounds like low-voltage to me. While you're at it, check the big L1 to the big aluminum ground wire, then the L2 to the same ground, for voltage. If you see -any- difference and your home is an older one, it's time to clean the meter box. It happens a lot. Alert your utility company. If it's not your meter box, then it's the transformer on the pole getting ready to spew nasty fluids. They'll do the checking though.
