Has anyone had the need to replace the CPU/motherboard in a WSII?

If yes...what are the Gotcha's for both replacement and programming?

Thank you...

If you can, either review or print the current wash setup. Also be sure to get any account information. Otherwise it's pretty straightforward and can be done in about 30 minutes.

Thanks Greg.....the tips and tricks where helpful.
The replacement was pretty strait forward and if you take your time to check things it was a 30 minute job.
Reason for replacement.....lost the relay that sent the signal to the razor for the top wash. I attempted to change relays (recommended by the Unitec manual) but it turned out to be a short on the CPU/mother board that was sending a false signal to the razor.
