Which is better: an inverter motor or a standard motor in a dishwasher?

Most modern dishwashers are equipped with inverter motors. Their predecessors, commutator motors, are now found in even the most budget-friendly models. However, manufacturers are trying to eliminate commutator motors altogether, even though these motors significantly reduce the cost of the equipment.

Let's find out whether an inverter or standard motor is better. Is it worth paying extra for an upgraded motor? We'll also tell you which dishwasher models are worth considering.

Advantages and disadvantages

Technology never stands still. Manufacturers strive to produce equipment that meets all quality standards and regulations. Today, the emphasis is on resource conservation, which is why inverter motors are preferred.

If we talk about the advantages of the inverter, they are as follows:

• low power consumption;
• long service life without maintenance;
• silent operation;
• the ability to automatically determine the energy consumption required to complete a cycle, depending on the load of the dishwasher.

Speaking about the disadvantages of inverter motors, it is worth noting:

• high cost;
• the ability to operate normally only with constant voltage in the electrical network (otherwise there will be failures and breakdowns);
• expensive repairs.

At first, inverter motors were installed in microwave ovens and air conditioners. Companies were trying to solve the problem of high energy consumption. Later, inverters began to be installed in washing machines and dishwashers. Today, these motors are the preferred choice in the production of household appliances.

Compared to engines of classical design

To understand why an inverter is better than a commutator, you need to understand how each motor operates. A standard motor maintains a constant speed and doesn't take into account the dishwasher's load. Therefore, even with a minimum load of dishes in the dishwasher, energy consumption will be the same as with a maximum load.

The inverter adjusts the rotation speed based on the dishwasher's load level.

An inverter motor doesn't always operate at maximum speed. A special sensor installed in the dishwasher detects how much the machine is loaded with. Based on this, the optimal motor speed is selected, preventing excess power consumption.

The collectors contain gears and belts that produce loud noises during operation. Dishwashers equipped with inverter motors operate virtually silently. This is due to the fact that there are no moving parts in the inverter design.

The best dishwashers with the latest motors

Choosing a new dishwasher is no easy task. Manufacturers offer a variety of models to suit every taste and budget. What should you consider when choosing your appliance?

• Dishwasher capacity (the number of place settings that can be washed in one load).
• Dimensions. This is especially true for built-in appliances.
• Manufacturer.
• Engine type (it is better to give preference to machines equipped with an inverter).
• Software "stuffing".

When choosing a new dishwasher, we recommend considering the Bosch SMV 25AX00 E. This full-size unit holds up to 12 place settings. It boasts complete leak protection, which is essential for safe operation.

Main technical characteristics of Bosch SMV 25AX00 E:

• type – fully built-in;
• energy efficiency class – “A+”;
• number of washing modes – 5;
• drying – condensation type;
• dimensions 60x82x55 cm;
• noise level – 48 dB.

The dishwasher has five wash modes: Automatic, Quick, Intensive, and Economy, as well as a Soak option. The dishwasher also features a water purity sensor and a delayed start timer (3 to 9 hours).

The modern Bosch SMV 25AX00 E dishwasher is equipped with an inverter. A special sensor determines the device's load level, after which the control module starts the motor at the required speed. This results in energy savings.

Another decent dishwasher in this price range is the Beko DDS 28120 W. This narrow model is only 45 cm wide. Its capacity is impressive – up to 11 place settings per wash.

The Beko DDS 28120 W is a freestanding unit. It has 8 wash modes, including:

• auto;
• delicate;
• fast;
• intensive;
• half load;
• economical;
• soak;
• self-cleaning.

Model specifications:

• capacity – up to 11 sets;
• drying – condensation type;
• energy efficiency class – “A”;
• noise level – 46 dB;
• Delay timer to start the cycle from 30 minutes to 24 hours.

This model has three load levels. Average water consumption per cycle is 8.7 liters. It has five temperature settings. A water purity sensor monitors water levels at all stages of the cycle.

When searching for a built-in dishwasher, consider the Weissgauff BDW 6039 DC Inverter. This modern and efficient dishwasher features a high-quality inverter motor and a special infrared beam that notifies you when the cycle is complete.

The machine features a large display. The wash chamber contains three functional baskets for cutlery. The dishwasher can hold up to 13 place settings at a time, with dimensions of 59.8 x 82 x 57 cm.

The machine has nine efficient programs (including three automatic smart modes) that will always help you select the optimal settings depending on the type of dishes and the level of soiling. The door opens automatically at the end of the cycle, ensuring natural air circulation.

Another interesting built-in model is the Midea MID45S130i. The dishwasher can be controlled remotely using the MSmartHome smartphone app. Key features of the dishwasher:

• capacity – up to 10 sets;
• dimensions – 44.8x81.5x55 cm;
• energy efficiency class – “A++”;
• noise level – 49 dB;
• number of washing modes – 5;
• Delayed start timer – from 3 to 9 hours.

The Midea MID45S130i features full leak protection. This slimline dishwasher uses up to 10 liters of water per cycle. Wash modes include Quick, Standard, Intensive, Economy, and Half Load.

A full description of the dishwasher, its software features, and resource consumption can be found in the equipment manual.

The next dishwasher, the Gorenje GV561D10, holds 11 place settings. It has been awarded the highest energy efficiency rating, A+++. The narrow design measures just 44.8 cm wide.

The dishwasher has five wash modes. It features a digital display, a load sensor, and a delay timer. At the end of the cycle, the door opens automatically.
