Using a dishwasher can save you time, water and even electricity and to prove it, My Kitchen Rules contestants have been put to the dishwashing test!


Finish Bosch Dishwasher Challenge

Did you know that a dishwasher can use as little as 6.5L of water per cycle? This means a family of four could save on average 57 litres of water per load, compared to handwashing. Can you imagine being able to clean 144 items with 6.5 litres of water?

By switching to a dishwasher, the amount of water saved over a year, compared to handwashing dishes can be more than 10 thousand litres per household.

The current drought woes have highlighted the need for efficient water management systems and concerted conservation efforts by all South Africans. While good winter rainfalls may relieve some of Cape Town’s water issues, droughts will continue to hound Cape Town and greater South Africa.

According to the Water Research Commission, South Africa will demand 17% more water than exists by 2030. The commission reports that the country’s water supplies are almost fully allocated, making it difficult for new enterprises to access water licences and placing a dampener on future economic growth.

“There is increasing pressure on South Africa’s water supply and if current population growth trends continue, domestic and industrial water demand will more than double by the year 2050,” says Dr Konanani Khorommbi, Project Manager: Institutional Reforms and Realignment for ‎the Department of Water and Sanitation.

“Now more than ever, we need a strong social, financial and political commitment to reduce future water use,” he continued.

Finish marketing director Raheel Dhaduk says water conservation should not only be the responsibility of the public sector.

“Corporate South Africa has an important role to play from an awareness and education perspective. The debilitating drought in Cape Town has highlighted just how important it is for every sector of the economy to get involved in addressing the crisis.”

Within this context, leading dishwashing brand, Finish, has leveraged its partnership with Bosch to demonstrate how dishwashers can support water conservation initiatives in the country and to do that, they enlisted My Kitchen Rules Season 1 contestants Andrew Ross and Brent Lindeque to take up the challenge in their quest to save water.

But there’s so much more to your dishwasher than just “loading it up and hitting wash.”

Dig a little deeper and you’ll discover a whole gamut of time-saving, grime-fighting tricks hidden up its sleeve! By the time you get to the end of this list, you’ll never see a dishwasher in the same way again.

1. Your Dishwasher has been Over 100 Years in the Making

Robert Bosch first established his workshop for precision and electrical engineering way back in 1886. However, it wasn’t until 1964 that Bosch Home Appliances released its first dishwasher. With more and more people looking to save time on housework in the 60s, Bosch’s contribution made washing dishes by hand a thing of the past and illustrated that cleaning up after a party doesn’t need to be a drag!

2. Uses Less Water than Hand-Washing

There’s a widespread myth that dishwashers use more water than hand-washing. however that couldn’t be further from the truth. A standard dishwasher uses around 7 liters of water per wash, while hand-washing generally uses up to 40 litres. And the new Bosch machines use as little as 6.5L of water per cycle. When you add up the numbers, switching from hand-washing to dishwashing can save you up to 9,200 litres of water per year.

3. Does not Necessarily Spike Your Electricity Bill

Another widespread myth is that dishwashers use a lot of electrictiy yet this isn’t exactly the case either! Modern dishwashers are designed to be energy efficient and use around 0.67 Kwh per load (depending on the washing programme) to heat up, pump and recycle the water in the machine. Hand-washing with heated tap water on the other hand can use up to 2.6 kWh per load!

4. It Cleans Dishes Better Than You

Let’s think about it: if you wash your dishes manually, you’ll be 1) using sponges which are hotbeds for accumulating bacteria such as E.coli and Salmonella, 2) potentially using cold rather than hot water, and 3) allowing your dishes to accumulate dust as they dry. Does that sound hygienic? Fortunately, using your dishwasher takes all 3 germ-preserving variables out of the equation!

5. Comes in 3 Different Construction Types

Free-standing: Standalone units like 60 cm, slimline, compact and tabletop dishwashers can be placed freely on the kitchen floor or tabletop. 60cm and slimline dishwashers can also be installed under the kitchen counter but they will not have a continuous plinth panel or be flushed with kitchen cabinetry.

Built-under / Integrated: Installed under the kitchen counter, built-under or integrated dishwashers have a visible fascia panel on the front of the dishwasher. As they have a continuous plinth panel and no worktop, built-under and integrated dishwashers have a flush fit with your kitchen cabinetry. What makes an integrated dishwasher different from a built-under unit is that it allows you to install a furniture front on the dishwasher door to match your kitchen cabinetry.

Fully Integrated: Installed under the kitchen counter, fully integrated dishwashers are seamlessly concealed behind your kitchen cabinetry. With a full-panel furniture front on the door and a continuous plinth panel, the fascia panel of fully integrated dishwashers are integrated into the top of the dishwasher door and can only be seen when the door is ajar.

6. Forget About “Pre-Wash”

Although many prescribe to “pre-washing,” it’s a waste of time, water and energy. All you need to do is to scrape off large bits of food that can get stuck and clog the drain filter with a spoon. Load it up then sit back and trust your dishwasher to do what it’s designed to do.

7. Filter Cleaning is Crucial

Every dishwasher has a filter which prevents large food particles from clogging up the drain. However, over time, this filter will accumulate grime. If you use your dishwasher regularly, you’ll need to do a bit of maintenance each month. Don’t worry though, it’s quite simple – all you need to do is remove the filter thoroughly with hot soapy water!

8. Your Dishwasher Needs You to Place Items Upside Down

This may seem like common sense, but have you been loading up your dishwasher the right way? Placing items upside down ensures that the water jets from the spray arms can give your dishes a proper clean.

9. Wash Certain Dishes by Hand

While it may be tempting to automate how you clean up everything in the kitchen, there are some items that you should keep well away from your dishwasher. For example, wooden dishes may warp or crack, glass which is not dishwasher-safe may become irreversibly cloudy, non-heat resistant plastic may be bent out of shape, and copper and aluminium wares may discolour. Do the right thing for the sake of your kitchenware!
