How to change the soap in the dispenser Xiaomi: instructions for all models

Xiaomi's automatic liquid soap dispensers are popular bathroom and kitchen gadgets that save money and maintain hygiene, but even these devices need to replace the detergent. Incorrect pouring can lead to clogs, breakages of the pump or leaks - so it's important to know all the nuances of the process.

In this article, we will break down the step-by-step instructions for all current Xiaomi dispenser models (including the Mijia Smart Liquid Dispenser and Viomi Smart Soap Dispenser), talk about compatible tools, typical errors and ways to fix them, and share life hacks on how to extend the life of the device and avoid common problems.

What Xiaomi dispensers support soap replacement

Xiaomi has several lines of automatic dispensers, and not all of them are designed to replace liquids on their own. Here are the key models in which you can update the detergent:

• 🔹 Mijia Smart Liquid Dispenser (LXD01ZM) — Classic model with a capacity of 300 ml, supports liquid soap and shower gel.

Models without collapsible design (for example, Xiaomi Mini Soap Dispenser with disposable cartridges) are not designed for manual soap replacement - you need to buy branded filling stations. You can specify the type of your dispenser in the Mi Home application or on the sticker on the back of the device.

If your model is not listed, check the documentation or contact Xiaomi support.Some devices (like the Mijia Smart Dispenser Pro) have unique refueling mechanisms that require separate instructions.

What soap can be poured into the dispenser Xiaomi

Not all detergents are suitable for automatic dispensers, and the use of the wrong composition can lead to:

• 🔧 Clogged tubes - due to high viscosity or particles (for example, in soap with scrub).
• 🔧 Breakdown of the pump - aggressive chemical components corrode seals.
• 🔧 Foam formation - some gels when shaken foam, which blocks the mechanism.

Here is the compatibility table for popular models:

Critically, Xiaomi dispensers are not compatible with alcohol-based products (such as antiseptics or disinfectant gels).

💡

Before the first filling of the new dispenser, wash the container with warm water with vinegar (1: 1) - this will remove the factory lubricant and prevent the formation of mold.

Step-by-step instructions for replacing soap

The soap replacement process is slightly different depending on the model, but the overall scheme is the same. Consider the universal algorithm with the example of Mijia Smart Liquid Dispenser (LXD01ZM):

1. Turn off the dispenser. Remove the batteries or disconnect the USB cable (depending on the model) to prevent the pump from accidentally operating during refueling.
2. Remove the top cover. Most models have latches on it -- gently press the side ledges and pull up. In the Viomi V-SD01, the lid is unscrewed counterclockwise.
3. Remove the soap container. In some dispensers, it's integrated into the case -- in which case, just open the filler hole (usually marked with the "OPEN" symbol).
4. Rinse the container. Use warm water and a soft sponge. Baking soda (1 tsp per 200 ml of water) can be used to remove the residue of soap.
5. Fill the new product. Fill the tank with no more than 80%, which will prevent overflows when the pump is running. For models with a foam generator (LXD02ZM), use only special foam formulations.
6. Make sure all seals are in place or leaks are possible. In sensor models (Viomi) after assembly, you may need to calibrate - hold the switch on 5 seconds.

For models with a cartridge system (for example, Xiaomi Mini Soap Dispenser), the process is different:

1. Press the lock at the bottom of the dispenser.
2. Remove the empty cartridge.
3. Install a new cartridge with soap (original or certified only).
4. Wait for the click, which means that the cartridge is fixed.

⚠️ Warning: Do not use cartridges from other brands – Xiaomi’s dispenser sensors may not recognize them and the device will refuse to work.

Frequent Mistakes and How to Avoid Them

Even when following the instructions, users often encounter problems, and here are the most common mistakes and ways to fix them:

• 🚫 The dispenser does not give out soap after filling Reason: Air plug in the tube or pump is not calibrated Solution: Press the issue button 3-5 times in a row to blow the air. If it does not help, restart the dispenser (remove the batteries for 10 seconds).
• 🚫 Soap comes out of itself. Cause: Seal is damaged or the container is full. Solution: Check the rubber ring on the neck of the container. If it's deformed, replace it (you can use a drugstore bubble seal).
• 🚫 The pump is buzzing, but the soap is not coming. Cause: A pipe clog or a too thick product. Solution: Rinse the tube with citric acid (1 tsp per glass of water). If it doesn't work, replace the soap with a less viscous one.
• 🚫 The dispenser gives too much/little soap Reason: Incorrect calibration or failure of settings Solution: In the Mi Home app, go to Device Settings → Calibration and follow the instructions.

If after the soap was replaced, the dispenser began to make extraneous sounds (squeaking, crackling), most likely, garbage got into the pump. Disassemble the device and clean the mechanism with a cotton swab dipped in isopropyl alcohol.

How to extend the service life of the dispenser

The average life of Xiaomi dispensers is 2-3 years, but with proper care, this time can be extended to 5 years.

• 🔄 Clean the container and tubes regularly at least 1 time a month. Use vinegar solution (1:1) or special dishes for dishwashers.
• 🌡️ Storage under the right conditions: Avoid direct sunlight and temperatures above 35°C – This leads to soap dissection and thickening.
• 🔋 In battery models, use only alkaline cells (e.g. Duracell or Energizer) and cheap salt batteries discharge quickly and can leak.
• 🛠️ Blockage prevention: filter the soap through gauze before filling, and it will remove any possible particles.

For models with touch control (Viomi V-SD01) additionally:

• Rub the touch panel with a soft cloth without pile.
• Do not use abrasive cleaning products – they will scratch the coating.
• If the sensor has stopped responding, reset the settings via the Mi Home app.

💡

The use of distilled water to dilute thick soap (in a ratio of 1:1) reduces the load on the pump and prolongs its life by 30-40%.

If you are away for a long time (for example, on vacation), empty the dispenser completely and rinse it. The soap left inside can dry and block the mechanism.

Alternative Refueling Methods (for Experienced Users)

If the standard soap replacement method doesn't work for you (for example, because you don't have the original soap), you can use alternatives, but remember, this can void the warranty.

1. Use of non-original means

Some users successfully fill Xiaomi dispensers with the following compositions:

• 🧴 Baby Liquid Soap (e.g. Johnson’s Baby) – suitable for all models due to low viscosity.
• 🧴 Shower gel without oils (for example, Nivea Soft or Dove).
• 🧴 Homemade solution: 100 ml of distilled water + 50ml liquid soap + 1 tsp glycerol (for softening).

Modification of cartridges

For dispensers with disposable cartridges (Xiaomi Mini) you can:

1. Carefully open the used cartridge with a knife.
2. Wash it and pour new soap.
3. Stick the incision area with heat glue or tape.

⚠️ Attention: When you open the cartridges, there is a risk of damaging the fluid level sensor. E02 (No cartridge, return the original container.

3. Pump replacement

If the pump fails, it can be replaced with a similar one from other devices (for example, from Aqara or Yeelight), the main thing is the coincidence of voltage (usually 3.7V or 5V) and the size of the fitting.

Where to buy original gas stations and accessories

Branded cartridges and soap for dispensers Xiaomi can be purchased:

Original cartridges cost between 300 and 800 rubles apiece, and be careful with fakes, which are often leaky or not recognized by the dispenser.

• A holographic sticker with the Xiaomi logo.

If the original cartridges are too expensive, look for compatible models from the Baseus or Zimi brands – they are cheaper by 30-50%, but require manual calibration of the dispenser.
