Energy class
The energy efficiency class characterizes the the economy of a dishwasher's electricity consumption. Initially, the classes were denoted in Latin letters from A (high degree of economy) to G (high consumption). But later, with the development of energy saving technologies, more advanced classes than A appeared. They are denoted by the letter A with a certain number of pluses (
A+,
A++, etc.); the more benefits, the higher the economy. Most modern built-in dishwashers comply with energy classes from A to
A+++(the last is 30% more economical than the original class A). More high consumption models, such as classes B and C, are much rarer and gradually disappear.
More economical models cost more, but the difference can be recouped in energy savings. Also note that the energy consumption class does not describe efficiency in general, but in comparison with other similar models; therefore, the actual consumption of a small class A device may be lower than that of a large class A++ model.
Noise level
The approximate noise level produced by the dishwasher during operation. In modern models, this parameter can range from 37 – 39 dB (muffled human voice) to 59 – 60 dB (loud conversation); more detailed decoding of what sound corresponds to a particular number of decibels can be found in special tables. Anyway, the
low noise level contributes to the comfortable use of the device. It is especially important if the dishwasher is to be used at night (for example, if there are reduced electricity rates at night).
Dimensions (HxWxD)
Dishwasher dimensions in height, width and depth. An obvious parameter; we only note that when determining the amount of space required for integration, the width and height of the unit are important.
In most modern built-in dishwashers, the width corresponds to one of the standard values (about a centimeter):
45 cm for narrow models,
60 cm for standard ones and
55 cm as a compromise between these dimensions. As for the second dimension, dishwashers with a height of up to 60 cm inclusive are usually classified as
compact, they require installation at a certain height above the floor.
Full-size models, with a height of more than 60 cm, can also be installed at floor level.
