The dishwasher can be easily protected from the carefree frolics of children by locking out the controls. We no longer need to worry about any accidental switching off the dishwasher or changes to the settings. Everything is washed according to plan!
The dishwasher uses a modulated sound tone to indicate a finished washing cycle, ready to be unloaded so nothing is left in for longer than required, especially when we are in a hurry. A long and steady tone is used to indicate a problem that we need to solve now.
