In this article, we will analyze all the stages of replacement - from choosing the right detergent to the intricacies of maintenance of popular models (Mijia Smart Liquid Soap Dispenser, Viomi). V3 others).

Xiaomi dispensers are designed to work with liquids of a certain viscosity. Using the wrong soap (such as a thick shower gel) can lead to clogs in the pump mechanism or false alarms of the infrared sensor. We will tell you which formulations are safe for the device, how to properly wash the tank and what to do if the dispenser stopped dosing the product after replacing it. You will also find unique data on the compatibility of the soap with specific models, this information is often not stated in official instructions.

What liquid soap is suitable for Xiaomi dispensers

Not all detergents can be put into an automatic dispenser.

• 🧼 Consistency: Optimal viscosity, like liquid hand soaps (like Dove or Fa) thick gels (like Nivea) or foamy compounds can clog tubes.
• 🔬 Chemical composition: avoid products with abrasive particles (scrabs) or aggressive solvents (acetone, alcohol) >They damage the plastic in the tank.
• 🌿 Eco-friendly: for models with Eco Mode function (e.g. Viomi) V3 Pro) better use of biodegradables.

Manufacturer recommends using the original Xiaomi Mijia soap (article) DJT11LM), But it costs 2-3 times more than its peers:

Important! Avoid oil-based perfumes (such as handmade lavender or citrus soaps) that leave sticky film on the walls of the tank that is difficult to wash.

Preparation of the dispenser for soap replacement

Before you pour a new product, you have to prepare the device properly, and neglecting this step is the main cause of failure of the pump mechanism.

1. Turn off power. If the dispenser is powered by the network (models Viomi). V3 Pro, take the plug out of the socket. For battery versions (Mijia Smart), remove the batteries.
2. Pour the residues of the old soap. Tin the device over the sink and press the dosage button 3-4 times until the foam stops coming out.
3. Rinse the tank. Use warm water (not hot!) and a soft sponge. To remove plaque, you can add 1 tsp of vinegar per 200 ml of water.

For models with removable tank (for example, Viomi) V3):

1. Press the latch at the bottom of the dispenser and pull the container up.
2. Wash it under running water, paying attention to the depression for the pump.
3. Dry all the details in the air (do not use a hair dryer!).

Step-by-step instructions for replacing liquid soap

The algorithm depends on the design of the dispenser, and let's look at two options: a fixed tank and a removable tank.

Option 1: Mijia Smart Liquid Soap Dispenser (Removable Reservoir)

These models have a top cover with a filler hole.

1. Turn the lid counterclockwise to the click. Don't put too much effort -- plastic thread!
2. Pour soap through the hole, without reaching the maximum mark of 5-7 mm (to avoid overflowing when heated).
3. Turn the lid clockwise to the point, make sure the sealing ring is in place.
4. Turn on the power. On models with a display (Viomi) V3 Pro) an indication of the level of the liquid will appear.
5. Test the dosage: put your hand up to the sensor or press a button. The first 1-2 servings can come out with air — that's normal.

Option 2: Removable tank dispensers (Viomi) V3, Xiaomi Youpin)

In these devices, the soap container is separated from the base:

1. Press the unlock button (usually located on the back) and pull the tank up.
2. Fill the container with soap to mark MAX (In some models, it is marked by risk).
3. Set the tank back up by aligning the guide grooves, and there's a snap of the lock.
4. Connect the power. The Refill Complete message (if supported) will appear on the display.

⚠️ Attention: On Viomi models V3 Pro after changing the soap can work automatic calibration of the pump. At this point (10-15 seconds) do not press buttons and do not interrupt the process - this can knock down the dosage settings.

💡

If the dispenser gives too little after replacing the soap, reset the dosage settings. To do this, hold the power button for 5 seconds until the beep (works on most models).

What to do if the dispenser does not work after replacing the soap

Typical problems and their solutions:

If the dispenser makes a buzz, but it doesn't give out soap, the problem is probably the pump.

1. Turn off the device for 10 minutes, then turn it on again.
2. Remove the tank and manually turn the gear of the pump (carefully, effortlessly!).
3. If it does not help – contact the service (on the Xiaomi model there is a 12-month warranty).

Care for the dispenser: how to extend the service life

Regular maintenance prevents 90% of breakdowns.

• 🧽 Weekly cleaning: wipe the case with a wet wipe, remove drops of soap from the sensor.
• 🔄 Replace soap: Even if the product is not finished, change it every 2-3 months (over time it thickens).
• 🔋 Batteries: In battery-powered models (Mijia Smart), replace cells every 4-6 months, even if the dispenser is working.
• 🌡️ Temperature: Do not place the device near heaters or in direct sunlight. The optimal temperature is 10-35°C.

For deep cleaning (once every 3 months):

1. Remove the tank and soak it in a solution of water with vinegar (1:1) for 30 minutes.
2. Wash the pumping mechanism (if removable) under the water stream, avoiding moisture on the contacts.
3. Dry all the details for at least 2 hours.

⚠️ Warning: Do not use chlorine-containing products (like White) to clean the tank, which break down the plastic and leave toxic fumes that are then mixed with soap.

Frequent User Mistakes and How to Avoid Them

Analysis of the service centers shows that 70% Xiaomi dispensers breakdowns linked to misuse-5 mistake:

1. Use of thick gel, leads to clogged tubes and overheating of the pump, always dilute the gel-like products with water (proportion 1:1).
2. Soap overflow, if you pour the liquid above the mark MAX, When heated, it expands and can damage seals.
3. Ignoring leaks, even small stains on the body eventually destroy the plastic, immediately wipe the device dry.
4. Soapless storage. If you leave the tank empty for a long time, the sealing gums will dry out and lose their tightness.
