I just saw an advert for a Bosch dishwasher, which reminded me that there’s a common misconception about how much water dishwashers use compared to a human dish washer. The ad says that a Bosch dishwasher uses as little as 9 litres of water, which is, “a lot less water than washing up by hand – saving as much as 50 litres for a similar load”. The ad also describes how much more hygienic dishwashers are too because they can wash in higher temperatures.
