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
turbo dry with heated air. The first option is more economical since it does not require energy. Besides, there is also an improved one —
with a heat exchanger. It provides significantly faster drying. And the recently appeared new type of drying
Zeolith combines both methods because it firstly collects residual moisture and then generates it into heat, which dries the dishes and belongs to the premium segment models. Note that not all machines can dry dishes to complete dryness; see Drying class for details.
End-of-cycle signal
Signal indicates that the machine has finished working. Many dishwashers are quiet, and without a special signal, it can be difficult to determine if the programme has ended.
Leak protection
It is an automatic system that controls the safe use of water by the dishwasher. If there is a leak, the water supply is blocked. And the already collected water is drained, which prevents the “flood” in the house.
Leak protection can be applied to the body, to the water supply hoses, or to both (full protection). It is worth noting that hoses with leak protection can usually be purchased and installed separately if the machine is not designed with any protection or protection only applied to the body.
Inverter motor
The presence of an inverter motor in the design of the dishwasher.
Inverter motors differ from conventional ones in the absence of a commutator with brushes (which is why they are also called brushless or brushless). Such units have higher efficiency (and, accordingly, less energy consumption), low noise levels and improved safety — the absence of brushes means a minimum likelihood of sparks. On the other hand, other things being equal, models with inverter motors are noticeably more expensive.
Energy class
The energy efficiency class characterizes the efficiency of the dishwasher's energy consumption. Initially, the classes were designated in Latin letters from
A(high degree of economy) to G (high consumption). However, later, with the development of energy saving technologies, more advanced classes appeared than A (
A+,
A++, A+++). The more benefits, the higher the savings. Most modern dishwashers comply with energy classes from A to
A+++(the latter is 30% more economical than the original class A).
Other things being equal, more efficient models cost more, but the difference can be recouped in energy savings. 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 machine may be lower than that of a large class A++ model.
