How to Open Xiaomi Soap Dispensary: 3 Working Methods + lifehack

Xiaomi’s liquid soap dispensers (Mijia, Viomi or Yeelight series) have become popular thanks to automated cleaning supplies, touch controls and stylish design. However, many users are faced with the problem of how to open the device’s case for refueling, cleaning or repair? The manufacturer often does not disclose this process in the instructions, leaving owners puzzled.

In this article, we'll look at all the official and alternative ways to open a dispensary, from the standard mechanism to jamming disassembly. You'll learn how to avoid breakages during opening, what tools you'll need, and what to do if the lid doesn't lend itself. And for those planning repairs, we've prepared a unique spare parts compatibility table for different Xiaomi models.

1.Official way: how to open the dispensary according to the instructions Xiaomi

Most dispensary models (e.g. Xiaomi Mijia Smart Liquid Dispenser or Viomi) V1) They have a magnetic or a snap-cap, and the manufacturer recommends the following algorithm:

1. Turn off the power. USB-cable or batteries (if the model is powered by them) will prevent the sensor from accidentally triggering.
2. Find the lock. The back or bottom panel usually has a small button or lever (often hidden under a rubber plug).
3. Press and pull. Hold the hold, gently pull the top cover over you. It should move off the guides.

If the lid doesn't lend itself, don't put too much effort into it, it can break the plastic latches. 80 percent of the time, the problem is with the dried soap that stuck the mechanism together. You can read the next section on how to deal with it.

2.If the lid is jammed: 4 reasons and solutions

The most common problem is jamming the lid, and here are the typical causes and ways to fix them:

• 🧼 Dry soap in the mechanism. Wipe the seam between the lid and the case with a wet vinegar wipe (1:1 with water). Wait 10 minutes and try again.
• 🔌 If the dispensary falls, heat the cover with a hair dryer (temperature 50-60)°C. This will bring plastic back to its elasticity.
• 🧲 Magnet shifting. Carefully tap the body with a wooden stick, the magnets can fall into place.
• 🔧 Latch break. You'll have to disassemble the case (instructions in section 4).

⚠️ Warning: Never use metal objects (knives, screwdrivers) to open the lid! NFC (if it's in the model).

If the dispensary is equipped with electronic locking (for example, in models with hand recognition), try resetting.

1. Hold the power button for 10 seconds.


2. Connect the device to the Mi Home app.




3. Go to Settings → Reset to factory.

3. Alternative methods of opening (if the standard does not work)

If the official method didn’t work, try one of these methods, which are suitable for most Xiaomi, Viomi and Yeelight models:

Method 1: Push-up latches with a plastic card

You're going to need any hard plastic card (bank card, discount card) that you can carefully run around the perimeter of the lid, press the latches, start at the corner where the latch is usually located. Importantly, don't push too hard to break the guides.

Method 2: Use of a suction cup

Smartphone screen suction cups (sold in electronics stores) are great for dispensaries with a smooth lid. Stick the suction cup to the center of the lid and pull up. If the lid doesn't move, sway it slightly from side to side.

Method 3: Warming up the housing

Heat the body with a dryer (warm air mode) for 2-3 minutes. The plastic will expand and the latches will weaken. Then try to open the lid in the standard way. Warning: do not direct hot air to the touch panel - this can damage it.

4. Complete disassembly of the dispensary: a step-by-step guide

If the lid doesn't open and the dispensary needs to be repaired (such as replacing the pump or board), you'll have to disassemble the body.

• 🔧 Cross screwdriver (usually) PH0 or PH1).
• 📱 Plastic mediator (or guitar mediator).
• 🧴 Residual soap drain container.
• 📸 Phone for photographing the process.

Step-by-step:

1. Turn the dispensary over and unscrew all visible screws on the bottom panel.
2. Carefully put the mediator on the bottom cover, starting at the corner, and it's held on the latches.
3. Disconnect the touchpad plume (if any) and it's usually attached with a connector. FFC/FPC.
4. Pour the residues of soap from the tank into the prepared container.
5. Unscrew the screws holding the upper part of the body, and remove it.

Inside you'll see:

• Soap pump (usually labeled) DC 5V).
• Control board with microcontroller (often ESP8266 or Realtek RTL8710).
• Liquid level sensor (infrared or float).
• Battery (if the model is wireless).

⚠️ Note: When disassembling models with a contactless sensor (for example, Viomi) V2) Don't touch the antenna with your hands, it can interfere with its calibration. Use an antistatic bracelet or gloves.

5.Spare parts compatibility table for Xiaomi dispensaries

If you need to replace a part (pump, board, battery), use this table to select compatible parts.

Parts can be ordered on AliExpress (search by part code) or at Xiaomi service centers. ~500-800 rubles, fees — ~1000-1500 rubles Analogues will cost less, but may require flashing.

💡

Before buying parts, check their compatibility by the serial number of the dispensary (located on the sticker under the body). Some models are identical in appearance, but have different connectors.

6. Frequent breakdowns and how to fix them yourself

Xiaomi dispensers rarely break down, but there are typical faults that can be fixed at home:

Problem 1: The sensor is not working.

Reasons:

• Soap contamination of the touchpad.
• Oxidation of the plume contacts.
• Damage to the board.

Decision:

1. Rub the panel with alcohol.
2. Reconnect the plume.
3. If it does not help, check the board with a multimeter (voltage on the sensor contacts should be available). ~3.3V).

Problem 2: The pump hums, but doesn't pump soap

It's probably a tube or valve that's clogged, and take the pump apart and rinse it in warm water with vinegar (1:3). If the valve is damaged, replace it. YL-V01 most models).

Problem 3: The dispensary is not included

Check it out.

• Integrity USB-cable.
• Stress on the board (should be) 5V entrance).
• Battery capacity (if the model is wireless).

If the board does not show signs of life, the voltage stabilizer (chip) may have burned down. AMS1117). You can replace it yourself if you have a soldering iron.

💡

90% of Xiaomi dispensaries are caused by pollution or wear of consumables (tube, valves), and regular cleaning extends the life of the device by 2-3 times.

7. How to avoid breakdowns: rules of operation

To keep the dispensary lasting longer, follow these recommendations:

• 🧴 Use only liquid soap without abrasive particles. Scrub gels clog the pump.
• 💧 Dilute the thick soap with water (proportion 1:1). This will reduce the load on the mechanism.
• 🧼 Clean the tank and tubes every 2 months. Use vinegar solution or special tablets for coffee machines.
• 🔌 Do not leave the dispensary in wet areas (for example, in the shower.
• 📱 Update the firmware through Mi Home, new versions fix sensor and pump bugs.

If the dispensary is used in a public place (office, cafe), install models with an anti-vandal body (for example, Viomi). V2 They are equipped with metal latches and anti-breaking protection.
