Many people believe that the dishwasher always saves energy compared to hand washing. In general it is true, but how you use it makes a difference. A very common—and little considered—habit may be raising your electricity bill without you noticing: Prewash dishes under the tap before putting them in the dishwasher.

It seems untrue and even contradictory, but no. We explain why you should avoid this common mistake in the daily use of the dishwasher (an error that not only affects your bank account without you realizing it but also adds work unnecessarily).

Why this mistake makes you spend more: don’t do this with the dishwasher

The problem is not just the water. When you rinse the dishes beforehand, the dish washing machine It loses efficiency because its sensors detect less dirt and adjust less intense but equally long cycles. This causes it to use energy without valid need and adds extra consumption due to the previous hot water.

In addition, many modern equipment is designed precisely to work with abnormal dirt, not with “already clean” dishes.

Another habit that makes the bill more expensive

Use long or high temperature programs “just in case.” In practice, intensive cycles consume more electricity and do not always improve the result if the load does not require it.

He long machine program, If activated frequently, it increases the accumulated expense at the end of the month. And many times it is not necessary!

How to use the dishwasher efficiently

Believe it or not, small changes can make a real difference in the use of your dishwasher:

  • Load well, without saturating: If it is too full, it washes worse and may require repeating cycles.
  • Choose the right program: The “eco” mode is usually sufficient for most uses and requires less energy.
  • Avoid pre-washing: Simply remove large food remains.
  • Use it full, but not overloaded: Constantly putting it at half load is less efficient.
  • Take advantage of cheaper hours: In many US states, electricity is cheaper at night.

Really I really like a dishwasher? It depends on the model and use, but, in general, a standard cycle can consume between 1 and 2 kWh. He eco mode nick that consumption but it is important to keep in mind that daily use with bad habits can significantly increase the monthly bill.

The most common mistake when using the dishwasher

As we said, there is a common mistake that you should banish: thinking that “more prior cleaning = better result.” It is now clear that, in reality, it is the opposite: it makes the dishwasher work worse and you spend more.

The dishwasher can be an ally in saving time and energy, but only if it is used well. Avoiding pre-washing, choosing appropriate programs and optimizing the load are simple decisions that, repeated every day, end up making a difference in the bill.
