Why to Disassemble Xiaomi Dispenser and When It Is Needed
Xiaomi’s liquid soap dispensers are popular devices in the brand’s smart home lineup, combining compactness, stylish design and functionality, but sooner or later, the owner faces the question of how to open the case to fill the tank, clean the mechanism or troubleshoot. Unlike traditional soapboxes, Xiaomi’s smart dispensers have hidden latches, seals and electronics, which require careful disassembly.
The main reasons users are looking for instructions to open the dispenser are: fluid replacement (especially if the model does not support top refilling), cleaning the nozzle from dried soap, replacing batteries or battery, and repairing the motion sensor or pump. Incorrect disassembly can damage plastic mounts or leaks, so it is important to follow proven methods.
In this article, we will look at the unique features of the mounts in different models of Xiaomi dispensers (for example, Mijia Smart Liquid Dispenser and Xiaomi Youpin Fresh Soap Dispenser),
The tools you need, the step-by-step instructions with the photo-analogues, and the typical mistakes that users make when they first open, if your dispenser stops responding to movement or gives out soap in jerks, you probably solve the problem by simply cleaning it, but you need to take it apart correctly.
What Xiaomi Dispensers are and their Features
Xiaomi has released several versions of automatic dispensers for liquid soap, and each has its own design nuances, below is a comparison table of the most common models that are found on the market.
| Model | Type of refueling | Volume of the reservoir | power supply | Features of disassembly |
|---|---|---|---|---|
| Mijia Smart Liquid Dispenser (LXD01ZM) | Top (through the lid) | 300 ml | 4×AAA batteries | Magnet cover, bottom latched. |
| Xiaomi Youpin Fresh Soap Dispenser (LXD02) | Lower (through compartment) | 400 ml | Built-in battery (USB-C) | Hidden latches on the sides, sealant |
| Xiaomi Smart Soap Dispenser Pro (LXD03) | Side (through hatch) | 500 ml | Battery 18650 (removable) | Fixing on screws under rubber legs |
| Deerma DX700 (joint-brand) | Upper. | 250 ml | 3×AA battery | Simple clip, but fragile plastic |
If your model is not listed in the table, pay attention to the way you refuel - this is the main reference point. LXD01ZM) They usually have a removable cover that opens without tools, but models with a lower or side hatch (for example, a sleeve, LXD02 or LXD03) Remove the tank because the tank is hidden inside.
Before you start the autopsy, check:
- 🔋 Power type: if the dispenser is battery-powered, it can last 3-6 months. Battery models last longer, but require periodic recharging.
- 💧 Nozzle condition – if the soap is not uniformly issued, it may be enough to clean the hole without completely disassembling.
- 🔄 Presence of warranty stickers - some models (for example, LXD03) have seals, the violation of which cancels the warranty.
Preparation for disassembly: tools and precautions
To open the Xiaomi dispenser without damage, prepare the following tools:
- 🔧 Plastic blade (or mediator) - to separate the latches.
- 🔩 Screwdriver cross (PH0 or PH1) — screw-model.
- 🧴 Isopropyl alcohol - for cleaning contacts and seals.
- 🧻 Soft cloth or wipes – to wipe the spilled soap.
- 📸 Smartphone - for photographing the dismantling stages (useful when assembly).
Warnings that are often ignored:
⚠️ Note: If the dispenser is connected to the network (models with the USB-C), Turn it off 10 minutes before disassembly, and the capacitors can hold a charge, which will short-circuit the circuit board inadvertently.
⚠️ Warning: Do not use metal tools to separate plastic latches, they leave scratches and can break the mounts.
If you're taking a dispenser apart for the first time, look at sealants that are sealed, and they prevent leaks, but they can break if you open them in a careless way. LXD02 and LXD03 seal is glued to the lid - it can not be torn off by force, otherwise soap will flow out through the slits.
💡
Before disassembling, take a picture of the dispenser from all sides, which will help to properly assemble it back, especially if the latches or wires are not symmetrical.
Step-by-step: how to open a Xiaomi dispenser
Consider the universal disassembly algorithm on the example of the popular Xiaomi Youpin Fresh Soap Dispenser model (LXD02). For other versions, we will point out the key differences.
Step 1: Power outage and preparation
1. If the dispenser is powered by batteries, remove them. If the battery is powered by batteries, completely discharge the device (press the soap release button several times until the pump stops working).
2. Turn the dispenser down with a nozzle and drain the remaining liquid into a separate container (if the tank is not empty).
Step 2: Remove the bottom cover (for models with a battery)
1. Place the dispenser on a flat surface with the button up.
2. Insert the plastic blade into the gap between the bottom cover and the body (on the side) USB-Carefully guide her around the perimeter, snapping clips.
3. When the lid starts to move, remove it completely. Underneath it, you'll see the battery and the control board.
What to do if the lid does not lend itself?
Step 3: Removing the soap tank
1. Once you remove the lid, you'll see a transparent tank with a tube. Carefully pull it upwards, it should come out of the grooves.
2.If the tank is not being retrieved, check if it is clamped by sensor wires. LXD03 The tank is attached to an additional screw under the rubber leg.
Step 4: Disassemble the top (to clean the nozzle)
1. The top nozzle cover is usually attached to two latches on the sides, and then you can shovel it back (from the button side).
2. Under the lid is a pump and motion sensor. Don't pull the wires, they're fragile!

Differences for other models
Mijia Smart Liquid Dispenser (LXD01ZM):
- 🔄 The lid opens with a simple click on the side clips (without tools).
- 🔋 Battery compartment is located at the bottom - unscrew 1 screw screwdriver.
Xiaomi Smart Soap Dispenser Pro (LXD03):
- 🔧 Under the rubber legs hidden 4 screws - they need to be twisted.
- 📱 Battery 18650 removable - can be replaced with wear.
💡
The rule of thumb when disassembling is that if something doesn't lend itself, you've missed a hidden latch or screw. Don't break the plastic, look for an alternative way!
Cleaning and maintenance: what to do after opening
Once the dispenser is disassembled, it's time to do a preventive cleaning.
- 🛑 Nozzle clogging - soap is given out in drops or not given out at all.
- 🔄 Uneven operation of the pump - the liquid is jerking.
- 🚫 False alarms of the sensor – the dispenser reacts without a hand.
How to clean the nozzle:
1. Remove the top cover (as described above).
2. Wash the nozzle under warm water using a toothpick to remove dried particles.
3. Blow the hole with compressed air (for example, a canister for cleaning equipment).
Cleaning of pump and tube:
1. disconnect the tube from the pump.
2. Wash it in soapy solution, then rinse with clean water.
3. check the pump for corrosion (especially if an aggressive fluid, such as an antiseptic, has been used).
Motion sensor maintenance:
1. Wipe the sensor lens with a cotton swab soaked in alcohol.
2. Check the sensor mounting - if it is shattered, fix it with glue or tape (temporary solution).
⚠️ Warning: If the dispenser still doesn't work properly after cleaning, it could be the electronics. LXD02 and LXD03 Often the transistor on the control board fails, and this will require soldering or replacement of the module.
Common Mistakes and How to Avoid Them
Even with careful disassembly, users often make mistakes that lead to breakdowns.
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of metal screwdriver for latches | Scratches, chipped plastic, broken clips | Use only plastic shoulder blades |
| Strong pressing on the tank when extracted | Cracks in plastic, leaks | Pull the tank smoothly, without distortions |
| Getting water on board during cleaning | Short circuit, failure of electronics | Wipe wet parts only after power out |
| Loss of sealing gum | Soap leaks, contact corrosion | Take a picture of the sealing position before removing |
Another common problem is the wrong build, like if you confuse polarity when you install a battery (in models). LXD03), The dispenser won't turn on, or if you don't close the lid, the soap will leak out through the cracks.
To avoid mistakes:
- 📸 Take photos of each stage of disassembly – this will help to assemble the device in reverse order.
- 🔄 Check the dispenser after assembly - whether it gives out soap evenly, whether it responds to movement.
- 🛠️ Don’t improvise with tools – if there’s no plastic shoulder blade, use a credit card or guitar mediator.
What to do if the dispenser does not work after disassembly
If the Xiaomi dispenser fails to turn on or malfunctions after assembly, follow the following steps:
- Check the power: 🔋 For batteries: make sure they are inserted correctly (polarity observed). 🔌 For battery models: connect to charging for 30 minutes, even if the indicator is not on.
- Reset settings: In models LXD02 and LXD03 Press the soap button for 10 seconds – this will reset sensor errors.
- Check the connection of the tube: If the tube is not sitting tightly on the pump, the liquid will not be supplied. Remove it and put it back on.
- Diagnose the board: Check the board for darkened elements (a sign of burnout). If you have a soldering iron, check the chain with a multimeter.
If the dispenser still does not work, it may be damaged firmware (in smart models with Bluetooth), in which case only the firmware through the official Mi Home app or contacting the service will help.
⚠️ Note: Xiaomi Smart Soap Dispenser Pro (LXD03) When you disassemble, you may lose the sensor calibration, and to restore it, press the button for 5 seconds until the indicator flashes blue.
