How to Open Xiaomi Soap Dispenser: 5 Proven Ways

Xiaomi's automatic soap dispensers (such as the Mijia Smart Soap Dispenser or Viomi Smart Soap Dispenser) have become popular because of their convenience and hygiene. But even these advanced devices sometimes have problems: the lid won't open, the mechanism is jammed, or you need to replace the cartridge. If you're faced with this situation, don't rush to bring the device to the service. In 90% of cases, the problem can be solved by yourself in 5-10 minutes.

In this article, we’ll look at all the ways you can open a dispenser, from standard procedures to emergency jamming techniques, and learn how to avoid future breakdowns, what tools you might need, and what to do if the device fails to respond to commands, and will be suitable for most Xiaomi models, including the Mijia, Viomi, and Yeelight.

We warn you right away: if the dispenser is warranty, you should contact the service center. Self-repair can cancel warranty obligations. For everyone else, we will start to analyze!

1. Standard way to open a Xiaomi dispenser

Most Xiaomi dispensers open on the same principle, through the top cover.

1. Turn off the power. If the dispenser is powered by the mains, remove the plug from the socket. If you're on batteries, remove the power (usually the compartment is on the bottom panel).
2. Find a lid lock. Most models have it on the back of the case, and it could be a small button, a lever, or a screwdriver groove.
3. Press or move the lock. For example, in Mijia Smart Soap Dispenser, you press the button and simultaneously pull the lid up.
4. Remove the lid. The movement should be smooth — don't put too much effort into not breaking the latches.

If the lid fails, check:

• 🔹 No visible damage to the lock or cover.
• 🔹 Is the button stuck due to soap or moisture.
• 🔹 Does the mechanism block the residue of soap inside the tank.

In some models (for example, the Viomi V-SDS01), the lid is fixed by a magnet, in which case it is enough to pull it up with a little effort, and if the magnet is weakened, you can replace it yourself (more on this in the section on repairs).

2.What to do if the lid is jammed?

If the standard method did not work and the lid does not open, the reasons may be as follows:

A critical mistake many users make is to try to open the lid by force using pliers or other tools, which almost always leads to cracks in the case or breakage of the lock.

⚠️ Warning: If the dispenser is connected to the Mi Home app, untie it in the device settings before disassembling. Otherwise, re-association may be required after assembly.

• 🛠️ Hot water. Pour warm (not boiling water!) water into the basin so that it covers the base of the dispenser for 2-3 cm. Hold 10-15 minutes - the soap will soften, and the lid will open easier.
• 🧲 If the lock is magnetic, attach a more powerful magnet (like a speaker) and pull the lid up.
• 🔧 Plastic card method. Carefully insert the card into the gap between the lid and the case and try to move the lock.

3. disassembly of the dispenser for cartridge replacement or repair

If you need not just to open the lid, but to completely disassemble the dispenser (for example, to replace the motor or clean the sensors), act according to the following scheme:

1. Remove the cover in one of the ways described above.
2. Remove the soap tank. It's usually just pulled up, but in some models it can be fixed with latches.
3. Unscrew the screws on the bottom panel. They can be hidden under the rubber legs -- gently tuck them in with a screwdriver.
4. Remove the bottom cover. This is where the electronics are: the control board, the motor and the sensors.
5. Disconnect the plumes (if you need to get to the board) and do this carefully so as not to damage the contacts.

Inside you'll see:

• 🔋 Battery or battery compartment (depending on model).
• ⚙️ Micromotor that drives the pump.
• 📡 Infrared sensor (responsible for automatic soap supply).
• 💧 Liquid supply tubes and valves.

If the goal is to replace the cartridge, then after removing the lid, just remove the old tank and install a new one. Make sure the seal ring (if any) is in place. In models with interchangeable cartridges (such as Mijia), they are usually sold complete with soap.

4. Removal of faults due to which the lid does not open

If the lid does not open due to a breakdown of the mechanism, here are the most frequent malfunctions and ways to eliminate them:

🔧 Breakage of the retainer

Symptoms: The fixator fails, does not fix the lid, or breaks completely.

Decision:

• If the fixator is plastic and cracked, you can restore it with a plastic glue (for example, Loctite).
• If you have a broken spring, replace it with a similar one (suitable from a ballpoint pen).
• If the fixator is metal and bent - carefully straighten it with pliers.

🧴 Soap hardened in the machine

Symptoms: the cover is "feeling," when opening, creaking is heard.

Decision:

1. Immerse the base of the dispenser in warm water with the addition of vinegar (1:1) for 20 minutes.
2. After softening the soap, wipe the mechanism with a cotton swab soaked in alcohol.
3. Lubricate the moving parts with silicone lubricant (do not use WD-40 – it is aggressive for plastic!).

🔋 Nutrition problems

Symptoms: the dispenser does not respond to commands, the cover is blocked electronically.

Decision:

• If the device is battery-powered, replace them, even if they are “nearly new.”
• If on the battery - connect to charging for 1-2 hours.
• Reset the settings by pressing the power button for 15 seconds.

💡

If the Xiaomi dispenser stopped responding to the hand movements, but the lid opens, the problem may be in the sensor.

5. How to avoid problems with the discovery in the future?

To avoid hitting the jammed lid again, follow these tips:

• 🧼 Use only liquid soap of the recommended viscosity; too thick or gel-like soap can clog the mechanism; optimal consistency, like a regular shampoo.
• 💧 Rinse the tank regularly. Every 1-2 months, pour warm water with vinegar into the dispenser and turn it on for 3-5 cycles to clean the tubes.
• 🔌 Turn off power during long downtime. If you haven't used the dispenser for more than a week, take out the batteries or disconnect from the outlet.
• 🌡️ Avoid extreme temperatures. Don't put the dispenser near heaters or in the direct sun - plastic can warp.

If you use self-diluted soap (e.g., mixed gel with water), watch the proportions. Too fluid consistency leads to leaks, too thick leads to clogging. Optimal ratio: 70% soap to 30% water.

⚠️ Note: Some Xiaomi Dispensers (e.g. Viomi) V-SDS01) If the lid doesn't open, check if the mode is activated in the Mi Home app. → "Security".

💡

Regular cleaning of the dispenser (every 1-2 months) prevents 90% of problems with opening the lid and prolongs the service life of the device by 2-3 times.

6. Video instructions and useful links

If the text instruction seems complicated, we recommend watching video disassembly for specific models:

• 📹 Mijia Smart Soap Dispenser – YouTube link (disassembly and replacement of cartridge).

On these resources you will also find:

If your dispenser model is not listed, try to find videos for "model name + disassembly" or "model name + repair" -- usually posted by enthusiasts or service centers.

7. When is the best time to contact the service?

Not all problems can be repaired by yourself. Contact Xiaomi Service Center if:

• 🔄 After disassembly, the engine buzzes, but soap is not supplied (possible breakage of the pump).

The cost of repairs in official Xiaomi services is usually:

Before the service visit:

1. Take a picture of the device and describe the problem (this will speed up the diagnosis).
2. Check if the warranty is maintained (if so, repairs can be free).
3. Ask about the possibility of replacing it with a similar model if the repair is not advisable.
