The issue I'm having is that pin 4 does not work. I ran through the diagnostics, and it seemed to be pointing to the solenoid for that pin. I ordered a replacement part and replaced it, but still no luck. I cleaned all of the switch contacts, and that didn't make a difference either. I did some further investigating, and found that none of the switches would activate that pin, so I'm thinking that it's not a particular switch that is causing it. So I tried using a multi-meter to see if there was anything that would indicate something odd, and it looks like there's current running to that solenoid all of the time, whereas the other solenoids don't seem to have that issue. Any ideas? I'm starting to think a diode or transistor or something on the board might be fried, but I just don't have any ideas. This is my first machine of any kind, so I'm a newbie when it comes to repair on these things.

Any nudge in the right direction would be greatly appreciated!

Thank you for your reply. I'm all for learning, especially since I would like to own this machine for a long time and know how to fix it if things come up. As far as sending the board out, any ideas ballpark what kind of $$ we're looking at, as well as somewhere good to send it?

Thanks!
