How to properly fill the dispenser for Xiaomi soap: detailed instructions with nuances

Xiaomi’s automatic soap dispensers are not just a fashionable gadget, but a practical solution to keep your home clean. Contactless fluid supply, stylish design and integration into the Mi Home ecosystem make these devices popular among smart home users. However, even such a simple device requires proper handling, especially when it comes to its first refill or changing detergent.

In this article, we will not only discuss the basic steps to fill the dispenser, but also reveal the nuances that the manufacturer does not mention, such as why some liquids clog the mechanism, how to avoid leaks, and what to do if the device stopped dispensing soap after refueling, and you will also learn which detergents are compatible with the Xiaomi Viomi Automatic Soap Dispenser and its analogues, and which are better to refuse, so as not to shorten the life of the gadget.

If you have just purchased a dispenser or faced problems during its operation – this instruction will help to avoid typical errors and prolong the life of the device.

What Xiaomi dispensers are and how they differ

Before you refuel the device, it's important to understand what model you're holding. Xiaomi has several different dispensers, and their designs affect the filling process.

• 🔹 Xiaomi Viomi Automatic Soap Dispenser is the most common model with a capacity of 300 ml, contactless infrared sensor and the ability to mount to the wall. Supports liquid soap, shower gel and antiseptic.

The main difference between the models is the type of product (liquid or foam) and the volume of the tank. For example, foam dispensers require special detergents with low viscosity, otherwise the mechanism will get clogged, and models with a UV lamp can not be filled with perfume agents, this can lead to yellowing of the plastic.

Also, pay attention to the type of attachment: some dispensers can only be installed on a flat surface (for example, a washbasin), while others come with a wall-mounting kit. This affects the ease of filling - in the suspended version, it is easier to drain the remnants of old soap.

What soap or gel can be poured into the dispenser Xiaomi

Not all detergents are suitable for automatic dispensers, the main criteria for choosing:

• 🚫 Prohibited components: chlorine, bleach, solvents (acetone, alcohol more than 70%).

It is best to use special products for automatic dispensers (for example, Viomi Foaming Hand Soap) or ordinary liquid soap without additives. If you want to save money, you can dilute the thick gel with distilled water in a ratio of 1: 1, but make sure that there is no precipitation.

⚠️ Attention: If you use a UV disinfectant dispenser (such as Mi Smart Antibacterial), do not fill it with essential oils or perfumes. Under the influence of UV light, they oxidize and leave a sticky coating on the nozzle.

Step-by-step: how to fill the dispenser of soap Xiaomi

The refueling process seems simple, but there are a few critical aspects that affect how the device will work, so follow this instruction to avoid leaks or breakdowns:

1. Turn off the dispenser. If the model is powered by batteries, remove them. USB — disconnect the cable, and this will prevent the pump from accidentally operating during refueling.
2. Remove the top cover. Most models have counterclockwise spins (like the Viomi); some models, like the Mijia Foam, have latches on the top, press them simultaneously.
3. Remove the liquid tank. Some dispensers have removable fluids, others have stationary fluids (you need to pour soap right into the body). MAX and MIN.
4. Rinse the tank (if it's not your first refill). Use warm water and a soft sponge. Don't use hard brushes or abrasives, they scratch the plastic, and dirt builds up in the microcracks.
5. Fill the detergent. Fill the tank to the mark. MAX, For Mijia Foam, only pour the liquid to the middle, and the volume will increase when you foam.
6. Put the tank back in place. Make sure it's firmly in the grooves. If the dispenser is crying (leaking from below), then the O-ring has shifted.
7. Close the lid and turn on the power. In models with batteries, check the polarity. USB-Wait for the charge indications.
8. Test the work. Put your hand up to the sensor, the device should give out the soap evenly, without jerking, if the fluid is intermittent, then the air in the system (refill).

If the dispenser does not work after refueling:

• 🔋 Check the batteries (they should be new, 1.5V).
• 💡 Make sure the infrared sensor is not closed (e.g. by labeling).
• 🔄 Reboot the device (remove the batteries for 10 seconds).

Typical gas station errors and how to avoid them

Even experienced users sometimes make mistakes that cause the dispenser to break down or deteriorate, and here are the most common ones and ways to prevent them:

• 🚰 If you pour soap above the label, MAX, When heated or shaken, it can leak through the valve. In foam dispensers, excess fluid leads to nozzles clogging.
• 🧴 Mixing different means, for example, if you put an antiseptic in a tank with residues of a shower gel, it can form a sediment that will clog the pump. Always flush the tank when you change the type of liquid.
• 🔋 Use saturated batteries. When the charge is low, the pump is jerked, and the liquid is released unevenly. Change the batteries every 3-4 months (or use Eneloop batteries).
• 🌡️ Operating at extreme temperatures: If the dispenser is outside or in an unheated room in winter, the liquid may thicken or freeze: +5°C +40°C.

⚠️ Warning: If you fill the dispenser with a thick gel and it stops working, do not try to push the liquid through with repeated pressing. This can burn the pump motor. Instead, disassemble the device, rinse the tank and tubes with warm water with vinegar (1:1), then dry for at least 12 hours.

Another common problem is nozzle clogging, which happens when you:

• A tool with insoluble particles was used.
• The dispenser stood idle for a long time (the liquid dried in the nozzle).
• Dust or pile got into the tank (for example, when filling with a sponge).

To clear the nozzle:

1. Remove the nozzle (usually it is unscrewed counterclockwise).
2. Wash it under a stream of warm water.
3. If the hole is clogged, use a toothpick or needle (carefully!).
4. Blow the nozzle with compressed air (for example, a canister for cleaning equipment).

💡

If the dispenser starts spitting unevenly with soap, try to scroll the pump manually, and if you turn off the power, press the issue button and hold it for 5-10 seconds, which helps remove the air traffic jams.

How often to fill the dispenser and when to change the liquid

The frequency of refueling depends on:

• 🧻 The volume of the tank (for example, 300 ml is enough for 300-400 servings at a standard dosage of 0.8 ml).
• 👨‍👩‍👧‍👦 Number of users (in a family of 4 people, the dispenser is emptied in 2-3 weeks).
• 💦 Type of means (foam is consumed more economically than liquid).

The recommended frequency of fluid replacement is once every 1-2 months, even if the tank is not empty. Over time, bacteria multiply in the soap, especially if the dispenser is in a high-humidity bath.

• 🤢 There was a bad smell.
• 🎨 The soap changed color or consistency (became cloudy, stratified).
• 🦠 On the inner walls of the tank, a raid is visible.

For models with a UV lamp (e.g. Mi Smart Antibacterial), the life of the liquid is extended to 3 months, but only if:

• You are using special antibacterial agents.
• The lamp is switched on automatically after each use.
• The dispenser is in a dry place (not in the shower).

How to prolong the life of the dispenser: care and maintenance

To ensure that the dispenser lasts more than a year (the average service life is 12-18 months with heavy use), follow these tips:

• 🧼 Monthly cleaning: Wash the tank and nozzle with warm water with vinegar (1:3) or special tablets for coffee machines (they dissolve lime plaque).
• 🔋 The right batteries. Use an alkaline battery (Duracell, Energizer) or an Eneloop battery. Cheap salt batteries quickly land the pump.
• 🌡️ Storage: If the dispenser is not used for a long time (for example, in the summer cottage), drain the liquid, flush the tank and store the device in a dry place.
• 🛠️ Blockage prevention: Every 3 months, pour 100 ml of distilled water through the dispenser, which removes the residue of soap from the tubes.

For touch-controlled models (such as Viomi), it is important to:

• Do not touch the sensor with wet hands - this can cause false positives.
• Wipe the body with a microfiber wipe (not paper towels – they scratch the plastic).
• Avoid direct sunlight – the IR sensor may fail.

If the dispenser starts to work worse (for example, it gives out soap with a delay or unevenly), try resetting the settings.

1. Remove the batteries for 30 seconds.
2. Hold the issue button for 10 seconds (until the indicator flashes).
3. Install the batteries back and test them.

💡

Regular cleaning of the tank and the use of quality detergents increase the service life of the dispenser by 30-50%.

What to do if the dispenser breaks after refueling

If the dispenser stopped working after refueling, don't panic -- 80 percent of the time, you can fix the problem without repair.

1. Check the power. Make sure the batteries are new and properly installed (plus to plus). USB-models check the cable and power supply (5V/1A).
2. Make sure the tank is installed correctly. If it's not fully twisted or the sealing ring has shifted, the pump won't be able to pump fluid.
3. Check the viscosity of the product. If the soap is too thick, dilute it with distilled water (1:1) and mix it.
4. Clean the nozzle. Remove the nozzle and rinse it under a stream of water. When you get a big blockage, use a needle or compressed air.
5. Reset the settings. Remove the batteries for 1 minute or press the reset button (if any).

If nothing helps, the following breakdowns are possible:

To disassemble the dispenser you will need:

• Screwdriver. PH0 (bottom-screw).
• A flat screwdriver (for slacking latches).
• A toothpick or needle (to clean the nozzle).
• Isopropyl alcohol (90%) for cleaning contacts.

⚠️ Attention: If you disassemble a dispenser with a UV lamp, don't look at it on, it can damage your vision. Also avoid touching the lamp with your bare hands (fat marks shorten its lifespan).

If the dispenser is warranty, do not disassemble it yourself - contact the Xiaomi service center. A list of official SCs can be found on the Mi Service website.
