The dishwasher can make household chores easier and, when used correctly, help you make better use of water and energy. However, consumption depends on the model, the program selected and usage habits.
You do not need to buy a new appliance to start optimizing its operation. These tips will help you get the most out of the one you already have.
1. Use the ECO program
ECO programs are designed to reduce resource consumption under normalized test conditions. They may last longer than other programs, but a longer duration does not necessarily mean they consume more electricity.
Consult the manual to learn about the features of the program on your model.
2. Load the dishwasher correctly
Wait until you have an adequate load before starting it, as long as you do not leave food scraps for too long.
Place plates and utensils following the manufacturer’s instructions. A poorly distributed load can prevent water from reaching all surfaces.
3. Avoid unnecessary pre-rinsing
In many cases it is enough to remove solid food scraps before placing the plates. Rinsing them under the tap can waste water you do not need to use.
If the dishes have particularly stubborn dirt, consult the appliance instructions and choose the appropriate program.
4. Dose the detergent correctly
Use a detergent compatible with your dishwasher and follow the manufacturer’s instructions. Adding more than necessary does not guarantee better cleaning and can leave residue.
Take into account the water hardness and the specific recommendations of your appliance.
5. Keep the filters clean
Food scraps can accumulate in the filter and affect the appliance’s operation.
Clean it with the frequency indicated in the manual. Before handling it, turn off the appliance and follow the recommended precautions.
6. Take advantage of scheduling functions
If your model allows you to schedule the start, you can adapt its operation to your schedule or to the conditions of your electricity tariff.
Check that scheduling is compatible with safe use and avoid leaving the appliance running when there are leaks or breakdowns.
7. Do not replace the dishwasher without comparing
If you are thinking of buying a new one, compare water and energy consumption per cycle, capacity, programs and acquisition cost.
A new appliance does not always pay off economically if the current one works correctly and is used little.
