How to fill the Xiaomi Mijia dispenser: full instructions

The Xiaomi Mijia automatic soap dispenser has become an essential element of the modern bathroom, offering contactless hygiene and stylish design. However, many owners face difficulties when first trying to replenish their supply of detergent for fear of damaging electronics or improperly assembling the mechanism. In this article, we will discuss the refueling process in detail so that you can enjoy the convenience of a smart gadget without unnecessary problems.

The first thing to remember is that the automatic pump requires careful handling of the pump mechanism. Unlike conventional bottles, it uses a complex foam system that is sensitive to fluid viscosity and tightness of the connections. The right sequence of actions guarantees long service of the device and stable operation of the sensor.

Before you start replacing the contents, make sure the device is off or away from water sources to avoid accidental switching on and short circuiting. Safety when working with appliances and liquids is priority number one. Let's take a closer look at each step.

Preparation for refueling and choice of means

The process does not start with the vial itself, but with the preparation of the workplace and the selection of the right liquid. Xiaomi dispensers are designed to work with special gels of a certain viscosity. Using the wrong tools can lead to clogging of the tube or failure of the pump motor.

If you plan to use the original replacement units, the task is simplified to a minimum. However, if you prefer the reusable use of a glass bulb, you will need to purchase or prepare a special gel.

⚠️ Warning: Never pour thick household soap, gels with large abrasive particles or alcohol-containing liquids in high concentrations into an automatic dispenser, as this can destroy pump seals.

For the refueling you will need:

• 🧴 Xiaomi Dispenser with an empty or discharged bottle.
• 💧 Liquid soap or special gel concentrate for auto-foam.
• 🚿 Warm water for washing the system (when changing the type of soap).
• 🧻 Dry napkin or towel.

Make sure you have everything you need before disassembling the device, which will avoid the situation where an open system is left unattended, which is especially important if there are children or pets in the house.

Dismantling of the pumping mechanism

The most important step is to remove the top of the device correctly, and the pump mechanism is attached to the threaded joint, but because of the pressure inside or the dried soap, it can unscrew with force, and it is important not to apply excessive force to the plastic elements so as not to break the thread.

Take the vial with one hand at the base, and the other firmly embrace the top cover with the motor. Start rotating the lid counterclockwise. If you feel strong resistance, try tapping slightly on the sides of the connection or warming the neck with warm (not hot!) water for a few seconds.

💡

If the pump doesn't unscrew, don't use tools, it will damage the body. It's better to heat the connection slightly with warm water to soften the frozen soap.

Once successfully unscrewed, you will have a view of the suction tube and the electronic unit. The electronics should remain dry, so try not to turn the lid over immediately after removal, letting the residue of soap drain back into the container or onto the napkin.

Visually inspect the tube for clogs, if you see crystals of soap or contamination, they need to be removed, and the cleanliness of the internal channels is the key to the stability of the foam sensor.

System washing and maintenance

Regular preventive cleaning prolongs the life of the device. If you change the type of soap or notice that the foam has become less thick, it is recommended to flush the system. To do this, lower the suction tube into a container of warm water and press the forced feed button (usually located on the end of the device).

Drain clean water 3-5 times through the system until a clear liquid without colored impurities comes out of the nose, which will remove the residues of the old gel and prevent mixing of different chemical compounds, which can cause reactions and clogs.

After washing, thoroughly wipe all available parts with a dry wipe. Pay special attention to the foam exit and the sensor area. Moisture on the sensor can lead to false positives or, conversely, to block the device.

Allow the parts to dry completely in the air for 10-15 minutes if water was used. Assembly of the wet mechanism is unacceptable, as water can get into the battery compartment or on the engine contacts.

Filling the bottle with soap solution

Now, to fill the container, if you're using the original Xiaomi removable unit, just insert it into the case, and if you have a reusable glass flask, pour the liquid carefully, trying not to create a lot of foam inside the vial until it's assembled.

The optimal filling level is before the neck narrows or before a special MAX mark, if it is provided by the design, and overflow can create excessive pressure when the lid is twisted, which will lead to the soap leaking out.

To prepare the solution with your own hands, mix liquid soap with water in the proportion recommended by the gel manufacturer (usually 1: 3 or 1: 4).

Once filled, wipe the bottle's neck dry again, ensuring that the thread fits tightly and the connection is tight.

Assembly and installation of the cartridge

Put the pump mechanism back in the vial. Put the thread together and start to twist clockwise. You don't have to put in a titanic effort -- tight enough to the point with your hand. Excessive tightening can deform the O-ring.

Make sure that the suction tube inside the vial is straightened and touches the bottom, but does not rest too much on it, which could block the current of the liquid.

If you use a model with magnetic charging or contacts, make sure that the contact area on the lid is clean and dry.

⚠️ Note: When assembly, make sure that the silicone pad does not jump out of its groove and does not skew, otherwise the tightness will be broken, and soap will flow along the walls.

Configuring and calibrating the dispenser

After installing the new cartridge, it may take several trial taps to fill the system with new fluid and start producing stable foam. Press the forced feed button or hold your hand to the sensor 2-3 times.

Some Xiaomi models allow you to adjust the portion size and sensitivity of the sensor through the Mijia app. Connect the device to your smartphone via Bluetooth to access advanced settings.

If the foam is too liquid, it may be too watery. If the foam is not going at all, check if the net is clogged at the exit. Adjusting the parameters in the application helps to adapt the device to a specific liquid.

This is normal for all foaming agents.

Possible problems and solutions

Even when properly operated, there may be failures, and most users are faced with a situation where the indicator is on, but the foam is not going, which may indicate the discharge of batteries or air entering the system.

Replace the batteries with new, preferably alkaline batteries, as they are better at keeping the load on the engine. Lithium batteries also show excellent results in the cold season.

• 🔋 Blinking: Replace batteries or charge the device.
• 💨 Spitting with water: too much air in the tube, do a few blank runs.
• 🚫 Reacts to the hand: wipe the sensor or check the distance (optimum) 3-5 centimeter).
• 📉 Weak pressure: clean the outlet or change the mixture to a less viscous one.

💡

90% of problems with the dispenser Xiaomi solved by replacing batteries with quality Alkaline or simply washing the tube with warm water.

If nothing works, the pump engine itself may have failed, in which case it is more advisable to purchase a new mechanism than to try to repair the old one, since it is easy to break the sealing of the factory assembly, and it is difficult to restore it.
