We have been replacing our old kitchen appliances and the new ones now come with whistles and bells, the iron beeps if it is left on plate down then turns off. Also beeps if it is left on too long without movement. The fridge and freezer beep if the doors are not closed fully. The washing machine beeps to let me know when it's finished. After the dishwasher expired several years ago and decided not t buy another one as fed up with spots, streaks and odd bits still on dishes. Finally gave in and bought a new one, this doesn't beep, but the crockery, glasses and cutlery have all come out squeaky clean. Adjustments can be made to salt and rinse aid according to water hardness. Just wish I had got one sooner and everything is so quiet.
