Thanks for the reply... I have taken apart both of those valves and even swapped them to see if the issue would switch sides.. I swapped the wiring too. No change. As far as the solenoids getting a signal, as soon as I disconnect one, the machine gives an error code, so I'm assuming that the electrical side of things is good. I have taken apart and inspected every solenoid involved with the drive circuit and they all look good. This machine is getting extremely frustrating. With an issue this obvious, I would think I should be able to find an obvious cause. Thanks for all the effort you are putting into this.
