For a dishwasher to last a long time and be economical with water and electricity, it must be used properly. Our 5 tips.
The dishwasher is handy when you need to clean large quantities. It can be very economical in water and electricity, as long as you follow a few tips.
Avoid rinsing dishes under running water.
The great advantage of the dishwasher is that it consumes very little water: it can wash up to 160 pieces of dishes with only 10 to 12 litres of water. So it would be a shame to waste water by rinsing the dishes before putting them in the dishwasher.
If you really want to rinse a very greasy dish, use the water that was used to wash vegetables or cook pasta or potatoes instead. It is put aside and at the end of the meal, it will still be hot and super efficient for rinsing.
Fill the dishwasher well
No need to run the dishwasher after each meal if it is not completely full. It will consume proportionally more than a full machine.
Choosing the right program
If the dishes are lightly soiled, the quick program may be suitable. However, if the dishes are very dirty or have dried out, it is better to use the economy program. It lasts longer but uses less water and energy.
Check the operating instructions for the consumption of each program in your dishwasher:
Newer machines are often equipped with an auto program, which is supposed to adapt consumption to the amount of dishes and the degree of soiling. Consumption would thus be lower when the dishwasher is not completely full and the dishes are not very dirty. The concern is that we have no control over consumption: we let the appliance decide and more often than not, consumption will be higher than the economic program.
Programming your dishwasher to start at the best possible time
The dishwasher is an appliance that lends itself well to programming. The ideal time to start it depends on each situation:
If you have a two-hour meter, you’d rather use the dishwasher during off-peak hours to pay less for electricity. This is usually between 10 pm and 7 am and on weekends.
If you have a simple meter, the electricity is at the same price whatever the time of day. It is best to avoid the peak consumption period (18-21h) and to favour the times when electricity production is most abundant, i.e. during the day.
If you have photovoltaic panels, the time when their production is at its peak is best: between 12 noon and 4 pm.
Maintain your machine well
For good washing results, the filter is cleaned regularly at the bottom of the tank. If any debris remains on the plates or dishes, it will end up there.
If 3-in-1 tablets are not used, make sure there is enough salt to soften the water and rinse liquid in the tank. The rinse liquid can be replaced with vinegar, provided that you first check that the machine’s seals are not made of rubber. Vinegar can make them porous.
It is also a good idea to wash the seals from time to time to prevent the development of mould.
