Dryer type
The dishwasher has a drying function. Drying can occur both due to the natural evaporation of water from the surface of the dishes (
condensation drying), and due to its
blowing with heated air; the first option is more economical, since it does not require energy and there is also an improved one —
with a heat exchanger; the second, in turn, provides faster drying. The recently introduced new type of
Zeolith drying combines two methods, as it first collects residual moisture and then converts it into heat, which dries the dishes and belongs to premium segment models. Note that not all dishwashers are capable of drying dishes to dryness; see drying class for details.
Auto door opening
Auto door opening at the end of the programme. This function not only provides additional convenience, but also plays the role of a signal about the end of work; in addition, the open door helps to speed up drying — excess moisture escapes through it.
Energy class (new)
This parameter characterizes the efficiency of electricity consumption by a dishwasher. Classes are denotet in Latin letters from A to G, in ascending order of energy consumption. Actually, more energy-efficient models have not been added to the A class, which eventually received the marking A +, A ++, A +++. Further development of technology has made it possible to go even further, and in order not to produce pluses in energy efficiency marking, manufacturers returned to the previous indices from G to A in March 2021, where
А is the most energy efficient dishwasher. But also
class B,
C,
D and even
E are also quite economical (no worse than A +++). Accordingly, the 2021 models will have modern markings, while older models will be marked in the same way.
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).
Beam on floor
The light indicator of work of the dishwasher. During the operation of the device, a special light mark is projected onto the floor in front of it; at the end of the programme, this mark goes out. Thus, one glance in the direction of the device is enough to determine its current state. And for fully integrated models (see "Type of installation"), this function is also convenient because it is no need to open the door to check the status of the device. Actually, the vast majority of units
with a "beam on the floor" are fully integrated.
Also note that in high-end dishwashers, not just a light mark in the form of a dot can be used, but a miniature projector, which is a
beam on the floor with a time indication or with other auxiliary information.
Control via Internet
Ability to control the dishwasher via the Internet. Thanks to this feature, the owner can control the device from almost anywhere in the world. In addition, most of these "smart" dishwashers are also capable of sending various notifications — for example, about the end of the programme, the remaining detergent and other consumables, interruptions in the water supply, their own problems, etc.
Connecting the dishwasher to the Internet can be done in different ways, but the most commonly used module is Wi-Fi.
The specific features of Internet control may vary. For example, in some models it is carried out through a smartphone, tablet or other gadget with a special application, in others you can use any Internet browser; and the set of dishwasher functions available to the user can also be different. However, this feature provides additional convenience anyway and can be very useful — especially for those who spend most of their time away from home.
