Modern bathroom gadgets, such as the Xiaomi Mijia Automatic Induction Soap Dispenser, are designed to simplify everyday life and maintain hygiene at a new level. However, many owners face a typical problem: how to open a Xiaomi touch soap to add fluid or replace power. The device design looks monolithic and lacks obvious screws or latches in plain sight, which often confuses users.
In fact, the company's engineers have designed a rather elegant but obscure mechanism for accessing the insides. An improper opening attempt can cause plastic mounts to break or damage electronics. In this article, we'll go into detail all the steps of dismantling, replacing batteries and maintaining the dispenser.
It is important to understand that before you start any manipulations, you need to make sure that the device is not in active mode to avoid accidental operation of the sensor, and it is also worth preparing a clean fabric and possibly tweezers to extract small parts. Next we will consider a step-by-step algorithm of actions that will help you safely disassemble the case.
Features of the design of the Xiaomi dispenser
The device is a sealed unit, where the main elements are a soap tank, a pump mechanism and a battery compartment. The touch panel is located on the front side and has no mechanical buttons, which increases the moisture protection of the housing. Inside there is an infrared sensor that responds to the movement of the hands.
The upper body is attached to the lower base using hidden screws and plastic latches. Xiaomi Mijia uses a standard approach to assembly of consumer electronics, where the aesthetic of minimalism hides all the fasteners, which is why without understanding the logic of the assembly, it is easy to damage the outer walls.
⚠️ Attention: Do not try to put the top cover with a knife or screwdriver from the dispenser - this will lead to the appearance of chips on glossy plastic and violate the tightness.
The liquid tank is removable and attaches independently of the main body with electronics, which allows you to wash the container under running water without removing the motor, but the pump assembly itself requires careful handling when removing the bottle from the neck.
Necessary tools for disassembly
Before you start the procedure, you need to have a minimum set of tools, you don't need a complex professional repair toolkit, you don't need enough basic things that every home has, and the right workplace preparation is also important.
- 🔧 Small cross screwdriver (size) PH0 or PH00) screw-up.
- 🧤 Dry rubber gloves for better grip on smooth plastic surfaces.
- 🧻 Paper towels or soft rags to wipe the body from moisture.
- 🔦 Lighting for hidden mounting zones (optional).
The use of metal tools should be kept to a minimum so as not to scratch the plastic. If you don't have the right sized screwdriver, you can try using a thin blade, but you should be extremely careful. The main goal is not to damage the screw thread and the integrity of the latches.
Step-by-step: how to remove the top cover
The most common question users have about the top module, where the electronics are located, is that you have to do a sequence of things to access the battery compartment, and the key is to find the hidden screw, which is often overlooked.
First, flip the dispenser up, and on the bottom, you'll see a rubber cap or a little recess, and that's where the locking screw is hidden, carefully remove it or unscrew it using a prepared screwdriver, and then the case will be looser, but it will still hold on the latches.
☑️ Checking before disassembly
Then, take the device with two hands: one hold the base, the other hold the top with the sensor. Smoothly but confidently pull the top up or turn it counterclockwise (depending on the specific revision of the model), you should hear the characteristic click of the latches' pullaway.
Replacement of batteries and maintenance
When you remove the lid, you'll see a battery bay. Most Xiaomi models use four standard AA batteries. When replacing them, it's important to observe the polarity indicated at the bottom of the bay. Contact oxidation is a common problem if the device has been with discharged cells for a long time.
If you're planning to replace batteries with batteries, make sure they have enough capacity and voltage. The sensory mechanism is sensitive to voltage drops, which can cause the dispenser to malfunction, and you can also wipe the internal contacts with dry cloth.
⚠️ Warning: Never mix old and new batteries, as well as different types of cells (alkaline and salt) in the same compartment, this can lead to leakage of the electrolyte.
In parallel with the replacement of the power supply, it is recommended to check the condition of the fluid intake tube. It should be clean, without claws. If a crust of dried soap forms at the end of the tube, it should be carefully cut or soaked in warm water.
Cleaning of the tank and pumping mechanism
The hygiene of the device depends on regular cleaning of the tank. The removable flask can be washed with any detergent, but the pump unit that is inserted into the neck requires a more delicate approach.
To clean the pump, wipe the outside with a wet wipe, and if the mechanism is clogged, you can only lower the bottom of the tube into warm water and turn the dispenser on several times so that it pumps clean liquid, which will help dissolve the residue of dried soap inside the channel.
| Element | Cleaning method | Frequency | Danger. |
|---|---|---|---|
| Reservoir | Washing under the tap | Once a month | No. |
| Pump | Washing with wet cloth | With every replacement | Water entering the engine |
| Sensor | Dry microfiber | As pollution progresses | Abrasives |
| Corps | Wet wipe. | Weekly | Strong chemistry. |
After all procedures are completed, make sure all parts are completely dry before assembling the device back. moisture inside the housing can lead to short circuit or corrosion of the contacts.
Device assembly and initial start
You put the batteries in the reverse order, you make sure they're installed correctly, you put the top lid on the base, you put the guides together, you press until you click the right click, or you turn it to lock, and then you twist the screw from the bottom.
After assembly, turn on the device. Usually, activation requires a short tap or triple tap on the touch zone, depending on the model. The indicator should light up, signaling readiness for operation. Xiaomi Mijia often has a charge level indication that will help monitor the state of the batteries.
What if the dispenser does not work after assembly?
If the device makes sounds but doesn't deliver soap, check if the tube is completely lowered into the liquid. The air in the system can interfere with the necessary vacuum to lift the soap. A few blank runs usually help solve this problem.
Frequent problems and ways to solve them
In the process, users may experience a number of typical malfunctions, often not in the electronics, but in the common blockage or battery discharge, and the diagnosis begins with the simplest causes.
- 💧 No soap, probably a meter nose or a tube with a traffic jam, you need to clean or pump.
- 🔋 Weak pressure: batteries run out or too thick soap is used. Try diluting the gel with water.
- 👁️ Sensor fails to respond: contamination of the infrared sensor or oxidation of contacts.
Sometimes users pour soap with large abrasive particles into the dispenser, which is strictly forbidden. The pump mechanism is designed to work with liquid gels of a homogeneous consistency. The use of inappropriate means can lead to mechanical jamming of the gears.
💡
Use liquid soap without large scrubbing particles to extend the life of the pumping mechanism of the dispenser.
If no method is working, the motor itself or the control board may have failed, and in this case, self-repair is complicated and requires soldering, so it is better to go to the service center or replace the device.
💡
Proper operation and use of high-quality soap without abrasives is the key to the long service of your Xiaomi touch dispenser.
