MYTH: Dishwashers are expensive to run

MYTH: Dishwashers are expensive to run.

Karl, the Bosch Engineer reports that the average energy cost for running a full dishwasher cycle is only 14p. Even with water and detergent included, it could cost you around 40p to wash a full family load in a Bosch dishwasher - that's less than a 2nd class postage stamp!
40p based on average water, energy and detergent prices paid (Ofwat, uSwitch, Nielsen 2014).

MYTH: Dishwashers use a lot of energy

MYTH: Dishwashers use a lot of energy.

When you consider how much time and effort is needed to wash up after a big family meal you might expect a dishwasher to use a lot of energy to do the same job. In fact, a modern Bosch dishwasher uses only 14p worth of electricity to heat up and circulate the water needed to make your dishes sparkling clean.

MYTH: A dishwasher fills up with water

MYTH: A dishwasher fills up with water.

Anyone who opens their dishwasher door mid-wash will see a surprisingly small amount of water – less than a bowlful in the base of the machine.
This is because a dishwasher heats, circulates and cleans very small amounts of water in each cycle. It's been calculated that 10 litres of water used in a Bosch dishwasher has the equivalent cleaning effect of 4,000 litres passing through the machine, with the most efficient using as little as 6.5 litres per cycle.

MYTH: Dishwashers are only for large families

Let Karl Explain Dishwashers

Many people think they won’t have enough dishes to fill a dishwasher and so not use it efficiently. However, dishwashers come in a range of different sized models, some as narrow as an open magazine at 45cm! Bosch compact dishwashers can fit on worktops.
Installing a slimline dishwasher is perfect for smaller families with limited kitchen space.

MYTH: You still need to pre-wash dishes

Let Karl Explain Dishwashers

Pre-washing may have been necessary with some dishwashers 20 years ago, but dishwashing technology has come a long way since then. There is no need to wash your dishes in the sink first when using a modern Bosch dishwasher along with the super-charged cleaning power of Finish.
Simply scrape off the heavily soiled items, load up and enjoy the time to be more productive.
