One appliance in the home that almost everyone uses regularly is the dishwasher. It’s one of those appliances that make our lives just a little bit easier. But have you ever stopped to think about how much electricity your dishwasher is using?

In South Africa, we are constantly being bombarded with news about load shedding and how we need to save electricity. So, it’s only natural to start thinking about ways to save power in the home. In this blog post, we will take a look at how much electricity dishwashers use in South Africa and some tips on how to reduce that amount.

How much electricity does a dishwasher use in South Africa?

Dishwashers use between 1 and 2 kWh of electricity per day in South Africa which is about 60% of the average daily use for a household. The average dishwasher in South Africa uses about 12 – 15 litres of water per cycle.

The national average price of electricity in South Africa is around R1.50 per kWh, so a dishwasher would cost about R3.00 to run each day.

How dishwashers work

A dishwasher is a household appliance that cleans dishes. The first dishwashers were manual and operated by a hand crank. Today, dishwashers are automatic and use electricity to operate.

Dishwashers work by spraying hot water and detergent on dishes. The detergent breaks up the food particles and the hot water washes them away. Dishwashers also have a rinse cycle that uses clean water to remove any residual detergent or food particles.

Most dishwashers have a built-in water heater that increases the water temperature during the wash cycle. This helps to improve the cleaning performance of the dishwasher.

Tips on reducing the amount of electricity your Dishwasher uses

Dishwashers use a lot of electricity which is an average of 1,200 watts per cycle. The good news is that there are ways to reduce the amount of electricity your dishwasher uses.

Here are some tips:

• Use the energy-saving setting: Many dishwashers have an energy-saving setting that reduces water temperature and cuts drying time. This can save you up to 50% on electricity costs.

• Scrape, don’t rinse: Rinsing your dishes before loading them into the dishwasher wastes water and energy. Just scrape off any food scraps—the dishwasher will do the rest.

• Don’t run partial loads: It’s more efficient to run a full load than a partial one. If you must run a partial load, select the appropriate cycle for the size of your load.

• Let dishes air dry: Use the air-dry setting or open the door when the cycle is finished to let dishes air dry. This can save up to 10% on energy costs.

• Avoid Overloading: Ensure that your dishwasher is properly loaded. Overloading the dishwasher can cause it to use more energy than necessary.

• Avoid Pre-wash cycle: Avoid using the pre-wash cycle if possible. This cycle uses a lot of water and electricity and isn’t always necessary.

• Select lower temperature setting: Choose a lower temperature setting when washing your dishes. A lower temperature will use less energy and still get your dishes clean.

• Use your dishwasher at Night: Run your dishwasher at night or during off-peak hours. This will help you save on your electricity bill.
