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.
Display
The preserence of
display in dishwasher. Typically, it is the simplest LCD screen capable of displaying multiple symbols. However, even such a screen provides additional convenience and makes the operation more visual: various notifications can be displayed on it, especially about the current operating mode, the remaining time, set timers, the remaining detergent, etc. More advanced dishwashers can be equipped with
a TFT display with advanced features. But this does not affect the washing process.
