A bad rotary encoder on User Interface (display) board or just a bad UI board can cause selection issues and explain weird code on screen, does wobbling knob around cause selection to jump around? Also pop the top off and look for cut or abraded wires going to UI and at CCU.

As for the lock; if lock is engaging, that usually means the pin switch is reporting the closed door and allowing the lock to throw. There is a second switch that tells CCU (Main Control) that lock is engaged, that would cause a door lock error if not functional. The more expensive thing is if the CCU isn't seeing the lock switches due to internal CCU error. I've seen both parts fail.

To answer your question : the CCU holds programming and cycle info in EEPROM, if that is corrupted your CCU is dead, or at least beyond reasonable repair.

Installed part today and it seems that the demons have been banished for now.

I am going to let Tsunade Hokage return to her laundry duties and see if she notices.

Enjoy the beer !!!

Thanks,
