Daan Tech broke their firmware update mechanism for lots of dishwashers in the field by losing their keys, more than once too. I own one such dishwasher and can't update the firmware without replacing the main board. They could certainly prevent cartridge resetting in newer dishwashers.

Where can I find more details about this?
