Washing machines with laundry weighing function

Not all washing machines with auto-weighing are actually capable of accurately calculating the weight of loaded laundry. This is more of an advertising ploy, allowing you to raise the price of the machine and distinguish it from less “modern” units. A truly weighing washing machine is equipped with a special sensor that can scan kilograms and adjust the wash cycle to the number of items. We’ll explain how automatic kg calculation works in the article.

Mechanism for determining the amount of laundry

A regular machine can guess how much laundry is in the drum, but only approximately. The function of such “weighing” is assigned to a pressure switch, which, through measurements of the water level, guesses the number of loaded items. It works like this:

• the hatch door closes;
• the machine begins to draw water, turning the drum to completely wet the laundry;
• the pressure switch controls the amount of incoming water and transmits information about the rate of intake to the control board;
• the electronic module analyzes the data received and approximately determines how much water is spent on absorption.

The slower the water rises, the more things there are in the drum. True, the pressure switch does not provide accurate data, since many lightweight fabrics absorb liquid less well, creating the illusion of an overfilled tank. But still, level measurements allow you to save water consumption by 20-30% and adjust the program according to the read data.

How is dry laundry weighed?

Modern machines with a laundry weighing function operate on a different principle. They are able to accurately determine the weight of things loaded into the drum in kilograms.Based on the measurements, refuse to start the cycle due to excess or propose a special program to save energy and water consumption.

The engine acts as a laundry scale. The motor in such models is located directly on the axis of the drum, which allows you to monitor the rotational force and the voltage generated by the engine. Using the obtained values, the washing machine processor calculates the load and displays the weight of the laundry.

It is prohibited to exceed the maximum weight of dry laundry allowed in a particular model!

Moreover, the program will not start until the machine has weighed. Conventional machines will immediately display the washing time after pressing the “Start” button, and then automatically start the cycle. Auto-weighing washing machines first determine the weight of the laundry, and only then offer the user a specific mode with the amount of water required, spin intensity, temperature and duration. This allows you to significantly save costs. Let's look at several models that offer weighing of laundry before washing.

Siemens WM16S740

By choosing Siemens WM16S740, you can accurately determine the weight of loaded items. Moreover, together with the measurement, the system will analyze the degree and type of contamination present, select the optimally suitable program from the 14 provided modes and immediately start the wash without the need to confirm the start. Due to the quick response and accelerated scanning, this will not take much time - the full cycle will be completed in 15 minutes. The quality will not suffer due to haste, things will be washed perfectly, and water and electricity will be saved.

Users will also be pleased with the AquaSensor water transparency control sensor.It is equipped with a special photocell, which, when rinsing, records the degree of cleanliness, and with excellent performance, reuses it. Full protection against leaks is also provided - AquaStop, which controls the movement of liquid and blocks the operation of the machine at the slightest suspicion of leakage.

The machine’s arsenal also includes a child lock and an accidental key lock, washing sound, delayed start for 24 hours, class A energy saving, imbalance and foam control. The control is electronic, so the system can simultaneously wash several types of fabric at once. Drum capacity is 8 kg with dimensions 60/85/59. The model will cost $296.

Gorenje Premium Touch WA 65205

With Gorenje Premium Touch WA 65205 you can find out what real weighing of laundry is like before washing. It is enough to load the drum and turn on the machine, after which the system will calculate the kg and offer the user the optimal washing program. The ideal selection of cycle duration, temperature and spin force is guaranteed by special sensors and UseLogic electronic intelligence. This technology allows you to collect and analyze information about the type of fabric and the nature of contamination, as well as ensure the minimum required consumption of water and electricity.

On Gorenje Premium Touch WA 65205 you can save the selected mode and use it if necessary.

The machine is controlled via a liquid crystal display, and all programs and commands are displayed in Russian. Information about the water heating temperature, spin speed, remaining washing time and liters and kW/h consumed is also displayed here.There is a cycle sound, as well as a delayed start for 24 hours, foam control, auto-dosing, and child lock. Safety is ensured by numerous sensors that record the degree of overheating, overflow and leakage.

In addition to the above, the machine offers 29 programs along with the option of “easy ironing”. The capacity of the model is 6 kg, dimensions are 60/85/59 cm. The unit costs about $455.

Electrolux Calima EWFM 14480W

The washing machine with auto-weighing from Electrolux is also not far behind. It also reads the weight of the laundry loaded into the drum, evaluates the nature of the existing stains and displays the most suitable program. The “trick” of the model is the Time Manager function, which allows the program to change the time on the selected system at its own discretion, speeding up or slowing down the engine. Thanks to this feature, washing machine owners receive optimal washing duration, high-quality results, as well as economical consumption of water, detergents and electricity.

In addition to convenient intelligent control, this front camera guarantees complete protection against leaks, 15 standard programs and child locking of the panel. The machine also boasts a drying board on the top panel, which is suitable for both synthetic and delicate fabrics. The drum capacity of 7 kg of dry laundry with a compact size with a depth of 60 cm is also pleasing. The cost of the model starts from $268.
