LG dishwashers Innovative Technology Review

Of course, LG consumer electronics does not require the introduction. LG TVs, air conditioners, projectors, washers, microwave ovens, etc are very popular among consumers. Dishwashers are no exception. For many years, LG dishwashers have successfully competed in the market. In 2016, the company introduced the new QuadWash series, including the very successful LDF5545ST QuadWash.

As known, 10 January 2018 at CES 2018, LG Electronics introduced a new concept of smart kitchen with voice control, which includes the InstaViewThinQ refrigerator, LMV 2031ST microwave, EasyClean oven and QuadWash dishwasher based on the LG ThinQ platform.

In theory, the LG EasyClean oven can send information to the QuadWash dishwasher, which selects the optimal cycle based on the cooked dish. For example, such intelligent dishwasher will choose a longer cycle with hotter water for washing dishes after cooking a greasy dish.

Innovative technologies

All LG consumer electronics uses a large number of innovative solutions and dishwasher are no exception.

LG dishwashers use following technologies.

1.The innovative QuadWash technology uses four sprayers instead of the traditional two, increasing dishwashing efficiency.

In addition, each of the blades can rotate in two directions. Periodic change of rotation direction ensures dishwashing from all sides.

2.TrueSteam provides preliminary cleaning of dishes from large food debris with the help of hot steam, which under high pressure enters the washing chamber.

Hot airflow effectively removes large and hard food particles. The integrated steam generator automatically adjusts the pressure and temperature of the steam.

3.EasyRack Plus increases the capacity due to the optimizing the configuration of the racks depending on the dishes size.

4.Steam Dual Spray function adjusts the intensity of the upper and lower racks. It provides the choice of the optimal mode for each rack while simultaneous washing, for example, fragile plates and pans.

5.Invertor Direct Drive increases efficiency by adjusting the steam supply intensity. Additionally, inverter technology provides high reliability, significantly reduces noise and electricity consumption. Usually, manufacturers give a guarantee of up to 10 years on inverter motors.

6.MultiMotion uses a rotating spray with detergent to reduce cycle times. The full cycle in this mode usually does not exceed 60 minutes.

7.SmartRack is an optional third rack for knives and forks. Usually, one of its compartments has a height adjustment to accommodate small cups.

Other features

1.SmartDiagnosis works similarly to the corresponding function of LG washers. The program analyzes the device failure, informs the user and displays the instructions. This option requires the LG Dishwasher & DW app on the smartphone. Typically, the diagnostic time does not exceed 1 minute.

But LG LDF5545ST does not support Wi-Fi. It uses NFC (near field communication), requiring the phone touching to the door top.

2.LoDecibel technology in conjunction with a multilayer soundproofing coating reduces noise. Typically, the noise of models with LoDecibel does not exceed 42 dB, which corresponds to a quiet conversation.

3.UV sanitization uses an UV lamp on the wall of the washing chamber to sterilize dishes.

According to the company, it removes up to 99.9% of bacteria. The mode works during 25 minutes after the end of the cycle. In addition, the UV sterilization cycle is programmed to run a second time if the dishwasher door has not been opened after two hours.

4.In addition, some LG models use Dual wash (washing dishes with various degrees of pollution), Extra Hot (maximum heating the water up to 80 ° C), and Sani (rinsing dishes at 77 ° C). The latest models have Auto mode, in which the device selects the time and temperature of the washing dishes based on data from turbiditimeter.

In general, LG LDF5545ST compares favorably with most popular models of the middle price segment up to $ 600, offering high quality washing dishes and excellent functionality. For example, it successfully competes with the popular Frigidaire Gallery FGID2466QF, and even Bosch SHPM88Z75N.

For 3 consecutive years, these factors have provided this model with a place in various TOP-lists among the best built-in dishwashers. 2019 was no exception and many experts again included the LG LDF5545ST in the list of the best models.

Of course, taking these factors into account affects the choice of the optimal dishwasher.
