How to pour soap into the dispenser Xiaomi: instructions for all models

Xiaomi's automatic liquid soap dispensers are a popular solution for the bathroom or kitchen that combines convenience and technology. But even with such a simple device, there are nuances: improper refueling can lead to leaks, clogs or breakage of the pump. In this article, we will examine all the steps of pouring soap, from choosing the right liquid to solving typical problems.

It is important to understand that dispenser models (e.g. Xiaomi Mijia Automatic Soap Dispenser or Viomi V3) differ in tank design and feed mechanism. We will look at universal rules and unique features for specific versions that the manufacturer often does not mention in official instructions. If your dispenser suddenly stops dispensing soap or dispenses too much of it, here you will find reasons and ways to eliminate it.

What Soap Is Right for Xiaomi Dispensers

Not all hand washing fluids or dishes are compatible with automatic dispensers.

• 🧼 Consistency: optimal viscosity, like a regular liquid soap (not gel or foam), too thick compounds clog the pump, and watery ones flow through the valve.
• 🌿 Composition: Avoid soaps with abrasive particles (scrabs) or large insoluble additives (such as beads) that damage the mechanism.
• 🔋 pH neutrality: Aggressive alkaline or acidic agents (e.g., to clean sewers) corrode the plastic tank.
• 💧 Alcohol-free: Alcohol-containing antiseptics can damage sealing gums, especially in models with an infrared sensor.

The manufacturer recommends using the original Xiaomi soap (ZNMS01JM), but analogues from Unilever, Procter & Gamble or Ecover will also work if they meet the above criteria. For a test before full refueling, pour 20-30 ml of the selected product and check the dispenser for a day.

⚠️ Warning: Soaps with fragrances or essential oils (such as lavender or citrus) may leave sticky sediment on the motion sensor. If the dispenser has stopped responding to the hand, wipe the sensor with a cotton swab dipped in isopropyl alcohol.

Preparation of the dispenser for refueling

Before you pour a new soap, you need to prepare the device correctly, and skipping this stage is the main cause of leaks and malfunctions.

Disconnect the dispenser from power (remove the batteries or disconnect the batteries) USB-cable)

Remove the remnants of old soap (if any)

Wash the tank with warm water without detergents

Dry all parts in the air (at least 30 minutes)

Check the integrity of the sealing rings-->

Pay special attention to the sealing ring on the tank lid. In Xiaomi Mijia models, it often deforms when closed improperly, leading to darts. If the ring loses elasticity, replace it with a similar one (suitable for medical vials with a diameter of 50 mm).

To flush the tank, do not use hot water (temperatures above 40°C can deform plastic) and hard sponges. The best option is a soft toothbrush and vinegar solution (1 tbsp. spoon per 200 ml of water) to remove lime plaque. After washing, thoroughly rinse the container with distilled water to avoid precipitation.

Step-by-step instructions for pouring soap

The refueling algorithm is the same for most models, but there are nuances for touch-controlled dispensers (such as the Viomi V3 Pro) and a mechanical pump (such as the Xiaomi Youpin).

1. Remove the top cover. In magnetically mounted models, pull it upwards, in threaded models, turn counterclockwise. Don't put too much effort: if the lid doesn't lend itself, check if the soap in the neck is blocking it.
2. Pour soap slowly along the wall of the tank to avoid bubbles. The optimal level is 1-2 cm below the maximum mark (some dispensers have a special valve to relieve excess pressure).
3. Close the lid and make sure it sits tight. In motion sensor models (such as Xiaomi Smartmi), after refueling, you need to hold your hand under the sensor for 3 seconds to calibrate.
4. In button dispensers (such as Viomi V2), press Mode to select a portion (usually 0.5 ml, 1 ml or 2 ml).

For dispensers with USB-Powered (e.g. Xiaomi Mijia 2) after refueling, disconnect and reconnect the cable - this will reset possible pump errors. In battery models (Viomi Mini), remove and insert the batteries back.

💡

If the soap is given out in jerks or with a delay, try turning the dispenser upside down for 10 seconds - this will help remove air plugs from the pump tube.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when refueling, and here are the most common ones and ways to solve them:

Pay special attention to batteries. Xiaomi dispensers often use AAA-type elements, but cheap ones (such as Trophy) may not provide enough voltage for the pump. The best option is Eneloop (1900 mAh) batteries, which can withstand up to 500 charging cycles.

⚠️ Warning: If the dispenser makes a loud buzzing sound after refueling, but no soap is supplied, it is a sign of a jammed pump. Immediately turn off the power and rinse the system with distilled water with a syringe (no needle!). Using running water can damage the electronics.

Features of refueling for specific models

Xiaomi’s dispensing device design has evolved, and each new model has unique nuances.

• 🔹 Xiaomi Mijia Automatic Soap Dispenser (1st generation): The reservoir is mounted on the thread, but the plastic is brittle - don't twist the lid with force).
• 🔹 Viomi V3 Pro: It has a double soap and lotion pump. When filling, make sure the tubes are not tangled (left for soap, right for lotion).
• 🔹 Xiaomi Youpin Smart Dispenser: Equipped with a UV lamp for disinfection. After refueling, press the button UV 10 seconds to activate.
• 🔹 Smartmi Automatic Foam Dispenser: Converts liquid soap to foam. To work properly, dilute the soap with water in a 1:1 ratio.

In models with a Wi-Fi module (for example, Viomi V3 Pro) after refueling may require reconnecting to the Mi Home application.

1. Open the application and go to Devices → Dispenser → Settings.
2. Select Reset and re-add the device via Add Device → Quick setup.
3. Update the firmware if a new version is available (in the device menu).

💡

For dispensers with Wi-Fi, always update the firmware after refueling - this prevents failures in the pump due to the incompatibility of the old software with the new soap composition.

How to extend the service life of the dispenser

The average life of the automatic dispenser Xiaomi — 3-5 years, but with proper care, this period can be increased to 7-8 years.

• 🔄 Clean every 2 months: Disassemble and flush the tank, even if it looks clean.Use a toothpick to clean the pump hole.
• 🌡️ Temperature: Do not install the dispenser near heaters or in direct sunlight. The optimum temperature is 10-35°C.
• 🔋 Power: In battery models, replace cells every 4-6 months, even if the dispenser is still working.
• 💡 Storage: If the dispenser is not used for more than a week, drain the soap and rinse the tank.The residue of the soap dries and blocks the mechanism.

For touch-controlled models (such as Xiaomi Smartmi), wipe the motion sensor with an alcohol napkin every six months. Dust and fat degrade the sensor. If the dispenser stops responding to the hand, check the sensitivity settings in the Mi Home app (Motion Sensor → Response Threshold).

If you use a dispenser in the kitchen for detergent, flush the system monthly with vinegar solution (1:3 with water), which prevents the formation of fatty plaque on the interior parts. For the bathroom, ordinary water is enough.

What to do if the dispenser breaks after refueling

If you pour soap, the device stops working, don't panic. 80 percent of the time, it's solved without repair.

1. In battery models, measure the voltage with a tester (should be at least one). 1.2In every element. USB-Try another cable and adapter (original power supply Xiaomi gives you a new power supply). 5V/1And).
2. Reset the settings. Most dispensers require holding the power button for 10 to 15 seconds until the indicator flashes, and in Wi-Fi models, the reset is done via an app.
3. Rinse the system. Pour the soap, pour the distilled water and turn the dispenser into continuous delivery mode (if any). Repeat 3-4 times.
4. Look at the pump. The Viomi V2 models show if the mechanism is rotating. If it's not, it may have burned (replacement required).

If the dispenser makes a grinding or crackling, this is a sign of a foreign body entering the pump. Carefully remove it with tweezers, previously turning off the power. In Xiaomi service centers, the pump replacement is performed in 1-2 days, the cost is from 800 to 1500 rubles (depending on the model).

⚠️ Warning: Do not disassemble the dispenser yourself, if it is warranty. Opening the case will cancel the warranty obligations. Official service centers Xiaomi in Russia can be found on the website mi.com/ru/service.
