According to the information on this page, they are divided into three types:
Built-in – the machine is completely installed in the headset. This method of installing is the most preferable, as it allows you not to violate the uniformity of the kitchen surfaces.
Fixed / partially built-in – such a machine can be partially integrated into the headset, that is, without a facade or put separately where it is convenient. Also, such models have one advantage – they are somewhat more convenient to use due to the placement of the control panel on the door. Thus, in order to start an already loaded machine, it does not need to be opened, the timer shows the time and the countdown of minutes until the end of the cycle.
Portable (tabletop) – it connects to the tap and is placed on the countertop. The capacity of such a baby is 4-6 sets of dishes. For a family of three or, say, one bachelor, this will be enough.
The capacity of the dishwasher should be 2-3 times more than the required minimum.
Capacity shows how many sets of utensils a model can wash in one cycle. The 1 set of dishes includes two plates (deep and flat), a cup with a saucer and a fork with a spoon. Dishwashers can accommodate from 4 to 17 sets. Small portable dishwashers hold just 4-6 sets of dishes. Narrow dishwashers hold 10-11 sets of dishes. Full-size models can wash from 11 to 17 sets of dishes. Since the dishwasher is most convenient to run once a day, it should contain all the dishes accumulated from breakfast, lunch, dinner, and snacks of all living in the house. So, for example, for a family of three, you should choose a dishwasher for at least 9 sets. It is advisable to add on pots and pans to this minimum.
Pay attention to water and electricity consumption.
The less water a dishwasher consumes per 1 cycle of operation, the less you will pay not only for water but also for electricity. Most modern models spend no more than 14-15 liters per cycle (0.85 kWh / cycle). Outdated models with a water flow rate of about 20 liters per cycle are rare. If you want to save even more, look for models with a flow rate of 8-9 liters per cycle (0.62 kWh / cycle). True, such economical dishwashers are more expensive. When choosing a dishwasher, pay attention to the flow of water both when working in economy mode and in a normal mode.
A standard set of 5-6 programs is enough.
It is advisable that the dishwasher has a half load function. Do not strive for a large set of temperatures and functional programs.
A basic set of 5-6 operating modes is enough:
Normal; Intensive; Quick; With preliminary soaking; Economic mode for washing lightly soiled dishes; The washing mode for fragile dishes ( glass goblets or expensive porcelain, etc.).
Here are some more useful additional features:
Half-load mode – allows you to wash not only a small number of dishes but also to wash dirty vegetables before cooking dinner.
If you like to make preparations for the winter and make jams, as well as if a family has/is planning a small child, then the sterilization function will not be out of place.
Very useful is the ability to delay the timer. It will allow, for example, to load the machine in the evening, and set it to turn on automatically at night, when everyone is asleep, and when water and electricity are cheaper.
For a family with a child, you should choose a model with the child protection option when the door and / or control panel of the machine is locked. It also protects children from hot steam.
Grade A washing quality class is the norm.
Even the simplest modern dishwashers have an A washing class, which means that the machine does the dishes very well. Want to wash your dishes perfectly? Choose models marked A+ (the more pluses, the better and more expensive the dishwasher is).
It is advisable to choose a machine with full leakage protection.
There are two types of leakage protection system:
The complete leakage protection system stops the water supply when a minimal excess or damage to the hoses is detected.
Partial leakage protection is provided by low-cost machines. They are designed in such a way that the water supply is interrupted when the special tray is overflowed.
A quiet dishwasher should have a noise level of up to 45 dB.
Turbo-drying is preferable if the priority is the speed of the machine
Almost all modern dishwashers have a drying function – either condensation type or a turbo type.
The simplest models dry dishes in a natural way: first, washed dishes are rinsed with hot water, then they simply dry, and condensate builds up on the walls of the chamber and, finally, flows into the drain. This drying principle is inconvenient for its duration. And while the dishes are drying, the machine does not signal a finish.
More expensive models have a fan that blows warm air overall wet dishes and dries them pretty quickly.
