Troubleshooting dead Calypso

Glad you got it all figured out!

Sucks that it failed in the first place.  I did not see where you found out what was the cause of the failure. 

I know you love this machine.  It is your daily driver right?

I've chased my tail on this kind of fault. Not only does the substitute device have to be "known good", so does the installation.
 
 
Brent, the touch panel was bad.  Yes, daily driver since approx Oct 2008 (I thought it was a year longer).  My IWL12 and FAV6800 are secondaries, and usually one other but I haven't pulled anything out of the garage to refurb since my aunt's Norgetag was done and sold.

It pretty much was obvious the panel was the problem since everything else checked out up to that point in the chain, but I was thrown off-kilter when I couldn't get a positive key matrix test on any of the three panels.

Electronics ... gotta love 'em and hate 'em.

Anyway, it's back ready for use this evening.  I changed the pump to the newer style (had a spare), and selected what should be an updated machine control board from the spares.  Will be interesting to see what differences may be in the cycle sequences.  For sure the post-spin fluff should be reduced from 30 seconds to 8 seconds.
 
 
I peeled the (strongly-adhesive) overlay off the bad panel.  Beneath it is basically an extension of the ribbon cable (also securely adhered) with mechanical momentary-contact switches for each selector button and associated LEDs.

There are seven extra LEDS that aren't visible through the overlay.
