What are the consequences of running the dishwasher without water or regenerating salt?
If the water supply is closed, the 'Water Inlet / Drain' indicator will flash and the cycle will not start. If the machine is run without regenerating salt when water hardness is above 0.7 mmol/l, limescale deposits may form on the dishes and in the tub. A dedicated indicator light signals when the salt level is low.
