How a semi-automatic washing machine works

Semi-automatic washing machines are clearly inferior to modern automatic washing machines in terms of functionality and convenience. However, they continue to be produced because they are cheaper and don't require central utilities. They're an excellent option for a summer house or country home. Washing with older machines is more difficult—they require more hands-on experience and knowledge. To avoid confusion, let's look at how a semi-automatic washing machine works and the different types available.

How does a semi-automatic machine work?

The design and operating principle of the semiautomatic machine are quite simple. The machine itself consists of a large tank with a motor. As soon as the user selects the “Wash” mode using the mechanical programmer, the motor begins to spin the activator – a circle with longitudinal bulges-blades. As the spinner rotates, the activator "ribs" constantly "stir" the laundry and foam the detergent. Ultimately, the fabric is washed clean.

Semi-automatic washing machines don't have a pump. The drainage system consists of a valve and a drain hose, but there's no pumping system—the waste liquid drains away by gravity. The user simply needs to switch the programmer to the "Drain" position, which opens the valve flap.

Semi-automatic washing machines are equipped with an activator – a circle with convex “combs” that are spun by a motor.

The main problem with semi-automatic machines is the lack of a transition from wash to rinse. To rinse the laundry, you need to perform a series of steps:

• drain dirty water;
• rinse the tank with the items in it with plenty of clean water;
• empty the tank again;
• rinse the items again (repeat until the foam has completely left the tank);
• drain the water;
• collect clean water;
• start the washing mode.

Another option is to transfer the washed items to a bathtub filled with water, rinse them, and then immediately spin them. This will reduce the washing time, but the process will be more labor-intensive. You'll have to haul the heavy items around several times.

The second difficulty concerns filling the drum with water. A semiautomatic machine can be connected to a central water supply, but more often than not, water must be drawn manually. You need to heat a bucket with a kettle, dilute it with cold water, and fill the drum.

The best semi-automatic washing machines

Semi-automatic washing machines have been serving people for over 30 years, but their design hasn't changed much. Modern washing machines remain just as inexpensive, reliable, and easy to operate. However, the range has expanded significantly, with manufacturers producing more models with varying features and prices. Let's take a look at the most popular ones.

• RENOVA WS-30ET. This freestanding, top-loading, actuator-operated washing machine holds up to 3 kg of laundry.

The washing machine is controlled by a mechanical programmer, ensuring a long service life. The machine measures 41 cm wide, 33 cm deep, and approximately 64 cm high. Prices start at $40.
• Evgo WS-30ET. This white and maroon washing machine features a top-loading actuator.

In semi-automatic washing machines, laundry is placed into the drum through the top lid.

Semi-automatic machines are the best option for a summer house or a private home. They're more difficult to wash, but still easier than doing it by hand.
