How to choose a stabilizer for a washing machine?
It's no secret that city and regional electrical grids are in poor condition. Voltage drops, outages, and surges threaten to damage your washing machine and other appliances. But while you can't do anything about your neighborhood's electrical grid, you can still protect your home. A voltage stabilizer for your washing machine is one such protection measure. This article is dedicated to choosing the right voltage stabilizer for your washing machine.
Types of stabilizers
There are several types of voltage stabilizers potentially suitable for household needs, especially for protecting washing machines and other expensive appliances. They differ in design, operating principle, and characteristics. So, what types of voltage stabilizers for 220V washing machines are available on the domestic market?
- Relay type stabilizers.
- Ferroresonant type stabilizers.
- Step type stabilizers.
- Electromechanical stabilizers.
Relay-type voltage stabilizers are the most common on the market. This is due to their low cost and excellent technical characteristics, which help mitigate most of the risks associated with operating electrical networks.
This stabilizer consists of a group of coils connected in a special circuit controlled by an electronic board, providing a high level of stabilization with minimal error. These devices are ideal for protecting washing machines.
Ferroresonant stabilizers are very expensive, noisy and rather finicky devices. They are extremely rare for household electrical systems, so they are virtually unavailable on the market. As far as we know, only two companies in the world produce household ferroresonant stabilizers: one in Germany and the other in Australia. These stabilizers are not suitable for washing machines.
Important! Ferroresonant stabilizers are more commonly used in industry. In everyday life, they cause more problems than they help.
Step-type voltage stabilizers operate using semiconductor elements that stabilize distortion in stages. This slightly slows the device's response time, but makes it more reliable, durable, and compatible with any 220V power supply. This type of voltage stabilizer is quite popular on the market and is well-suited for washing machines.
Serial-drive (electromechanical) stabilizers consist of tracking units and several transformers, which essentially perform the stabilization. Moreover, the stabilization is very high-quality, with very little error. The cost of the device is also low due to the simplicity of the design and the low cost of the components.True, the working life of such devices is very limited, a maximum of 5-7 years, but for this price, in general, this is not bad.
What technical parameters should I choose for my device?
While it's good to have a washing machine with electrical safety, it's not wise to buy a stabilizer just for it, especially since modern appliances allow you to connect multiple appliances at once. For example, in addition to the washing machine, the refrigerator, dishwasher, and dryer also need protection.
It's up to you to decide which devices to protect and which not. The key is to choose the correct voltage stabilizer power when purchasing. If the stabilizer's power is insufficient, problems may arise, including equipment shutdowns.
What technical parameters should a stabilizer have to effectively protect a washing machine and other household appliances? The main parameter to pay attention to is power. The power of the stabilizer must be sufficient to supply all devices connected to it.
Please note! Calculate the stabilizer's power output before purchasing. When making your calculations, allow for a power reserve of at least 20%.
How do I calculate the power of the stabilizer I need to buy? Let's take a step-by-step approach.
- We determine the number of devices that will be connected to the stabilizer in addition to the washing machine.
- We take the instructions from all connected devices, find the power consumption of each device, and add it up. For example, the total comes out to 3.5 kW.
- Add another 20% to 3.5 kW, which gives 3.5 + 0.7 = 4.2. Accordingly, the future stabilizer must have a power of at least 4.2 kW, and rounding down is not allowed.
Another technical parameter of the device is the number of phases. Some consumers ask whether they should buy a 3-phase or single-phase device to protect their washing machine. This will depend on your home's electrical system. The vast majority of home electrical systems are single-phase, but three-phase systems are also available.
To find out what type of electrical network you have, look at your electric meter. They usually indicate whether it's single-phase or three-phase. If it turns out your electrical network is single-phase, then you'll need a single-phase voltage stabilizer. But If the network is three-phase, then there are options: you can connect either a three-phase stabilizer or three single-phase ones, everything will depend on the load on each phase. You can't do without consulting an electrician here.
When connecting the washing machine to the stabilizer, do not forget to also additionally protect the electrical network by selecting and installing RCD or residual current circuit breakerThis device will protect your machine in the event of a severe voltage surge that goes beyond the stabilizer's operating range.
Overview of stabilizer models and manufacturers
Now that we've covered the general questions, let's review the best stabilizer models and their manufacturers. Our selection was compiled with the help of experienced professionals, and we hope it will help you make the right choice that won't disappoint. So, here's a look at the best stabilizer models suitable for washing machine protection and their manufacturers.
The Voltron PCH-3000 is a voltage stabilizer designed for household single-phase 220V networks. This device combines two stabilizer designs—relay and step-type—to achieve the fastest stabilization with minimal errors. The device has a power of 3 kW. It can stabilize input voltage from 105 to 265V and output a stable 220V. Suitable for installation in unheated spaces. Dimensions are 320 x 220 x 136 mm. Average price: $100.
The device is manufactured by the renowned Russian manufacturer ETK Energia LLC, a company with many years of experience in the electrical equipment market. The company has production facilities not only in Russia but also abroad, particularly in China. Stabilizers manufactured at the Moscow-area facility are considered the best, while the Chinese-made version is inferior.
UPower ACH-3000. A voltage stabilizer for single-phase 220V household networks. This device, like the previous one, combines two stabilizer designs—relay and step-type—for the fastest stabilization with minimal errors. The stabilizer has a power of 3 kW. It stabilizes input voltage from 120 to 280V and outputs 220V. Suitable for installation in unheated spaces. Dimensions: 285 x 192 x 203 cm. Average price: $80.
The device is manufactured by the Chinese company Foshan Nanhai Yinghua, which is quite well-known in certain circles. Over the past 10 years, the company has earned a reputation for producing high-quality products. Indeed, there are virtually no negative customer reviews for Foshan Nanhai Yinghua stabilizers.
Energy ASN-5000. A voltage stabilizer for single-phase 220V household electrical systems. This step-relay voltage stabilizer is ideal for protecting multiple household appliances. Its power is 5 kW. It stabilizes input voltage from 110 to 270V. Can be installed in unheated rooms. Dimensions: 203x192x285. Average price: $108. The stabilizer is manufactured by ETK Energia LLC.
Please note! This stabilizer is quite compact, yet powerful enough to protect several large appliances, including a washing machine.
In conclusion, choosing a good stabilizer for comprehensive protection of your washing machine isn't all that difficult these days. You just need to know the specifications of your home network and the number of appliances you plan to connect and choose a stabilizer based on that. But even if you have trouble calculating the power, don't worry—you can always consult with a specialist.

THANK YOU VERY MUCH!
The stabilizer power is indicated in VA, not in kW!
Which stabilizer would you recommend for my refrigerator? I can't decide which brand is best. For example, I was considering models from Resanta and Rucelf.
