Disassembly of the dispenser for Xiaomi soap: instructions with photos and nuances

Xiaomi’s automatic soap dispensers are popular devices in the brand’s smart home line that combine compactness, functionality and stylish design. Models like Xiaomi Mijia Smart Soap Dispenser or Viomi Smart Soap Dispenser (branded Xiaomi) feature infrared sensors, contactless dosing and even backlighting. However, over time, any gadget requires maintenance: cleaning from plaque, replacing batteries or repairing the fluid supply mechanism.

It’s easy to disassemble Xiaomi’s dispenser, but the process has nuances that the manufacturer doesn’t mention. In this article, you’ll find a step-by-step photo instruction, a list of necessary tools, and typical errors that lead to a device breakdown. We will analyze both basic models with a mechanical pump and advanced versions with electronic control, for example, Viomi. V-SOAP01 Mijia MJTD01YL.

We warn you right away: if your dispenser is still warranty, disassembly can cancel it. But for devices older than a year or with an expired warranty, self-repair is often the only economically viable solution - the official Xiaomi service in Russia is not always taken for repairing such accessories.

Preparation for disassembly: tools and security measures

Before you start, make sure you have everything you need. Most Xiaomi dispensers are disassembled without specialized tools, but some models (such as those with sealed enclosures) may require additional fixtures.

• 🔧 Plastic blade or mediator - for careful putting of the cover (metal screwdrivers scratch the body!).
• 🔋 New batteries (if you are planning to replace them) AAA lithium CR2032 (model).
• 🧴 Isopropyl alcohol 70% – for cleaning contacts and sensors.
• 🧻 Soft fabric or napkins without pile – to wipe the internal details.
• 📸 Smartphone – to photograph the process of disassembly (useful when reassembling!).

Also, prepare your workspace: close the desk with paper or cloth to avoid losing small parts. If the dispenser has not been used for a long time, check the fluid level before dismantling - sometimes the problem lies in the dried soap that blocks the pump, not in the electronics.

⚠️ Note: Some Xiaomi models (e.g. Viomi) V-SOAP01) They have sealed silicone pads under the tank lid, and if they're damaged, the device will leak.

Step-by-step disassembly of the dispenser: from the cover to electronics

The disassembly process can be divided into three stages: removing the top cover, extracting the liquid tank, and (if necessary) accessing the control board.

1. Remove the top cover.

Most models have a lid attached to the latches and no visible screws to remove it.

1. Place the dispenser on a flat surface with the sensor up.
2. Insert a plastic blade into the gap between the lid and the body on the opposite side of the dispenser (usually there are fewer mechanisms).
3. Carefully press and drive the shoulder blade along the perimeter, alternately snapping the locks.

If the lid doesn't lend itself, don't use excessive force -- you may have missed the hidden lock. MJTD01YL, For example, an additional latch is hidden under the decorative lining of the sensor (it can be tucked in from the side).

2. Removal of the liquid tank

Once the lid is removed, you will see a tank (usually transparent or white) that can be:

• 🔄 Removable – just pull up (for example, in Viomi) V-SOAP01).
• 🔧 On screws - requires unscrewing (found in early versions of dispensers).
• 🧲 On magnets - gently pull up while holding the body.

Notice the fluid supply tube, which connects the tank to the pump. Don't pull it so you don't tear it off. If the tube is clogged, you can wash it with warm water and soap (no aggressive detergents!).

Access to electronics (if necessary)

If the problem is a broken sensor or a faulty pump, you'll need to get to the board.

1. Unscrew the screws on the bottom of the body (usually under rubber legs).
2. Carefully disconnect the halves of the body, starting from the opposite side of the dispenser.
3. Disconnect the plumes connecting the board to the pump and sensor (remember their location!).

On the charge, pay attention to:

• 🔋 Battery contacts – oxidation can lead to unstable operation.
• 📡 Infrared sensor – if it is contaminated, the device will not respond to the hand.
• ⚙️ Micropump - when clogging emits buzz, but does not pump liquid.

Cleaning and maintenance: how to return the dispenser to work

Most often, Xiaomi dispenser stops working because of dried soap in the tube or oxidized contacts.

1. Cleaning of the tank and supply tubes

To flush the system:

1. Pour warm water with vinegar into the tank (1:1) Leave it on 10-15 minute.
2. Press the hand-feed lever several times (if any) to allow the fluid to pass through the tube.
3. Wash with clean water and dry for at least 2 hours before assembly.

Don't use alcohol or acetone to clean the tube - they can damage the silicone seals! To remove persistent deposits, a soft bristling toothbrush is suitable.

Cleaning the infrared sensor

If the dispenser doesn't respond to the hand, the problem may be a contaminated sensor to clean it.

1. Wet the cotton swab in isopropyl alcohol.
2. Gently wipe the transparent sensor lens (usually located under the top cover).
3. Please. 5-10 minutes before testing.

If after cleaning the sensor still does not work, check the connection of the plume with the board - it could move away during disassembly.

Replacement of batteries

Weak contact or dead batteries are common causes of malfunctions.

• 🔋 Use batteries of the same brand and type (for example, only Duracell) AAA).
• 🧹 Wipe the contacts in the compartment with alcohol - oxidation worsens conductivity.
• ⚡ Check the polarity: "+" and the "-" must match the marking on the body.

If the dispenser flashes after replacing the batteries, but does not work, perhaps the built-in lithium battery (in models with a battery) has died, replacing it requires soldering and better trust the specialists.

💡

To extend the life of batteries, turn off the dispenser overnight (if there is a power button) or use the model with the power button. USB-food (e.g. Viomi) V-SOAP02).

Typical breakdowns and ways to eliminate them

Even with careful operation, Xiaomi dispensers can break down, and the table below shows the most common malfunctions and options for repairing them.

If the pump is buzzing but not pumping fluid, the problem may be the worn membrane.In some models (e.g. Mijia) MJTD01YL) It can be replaced:

1. Disassemble the body before accessing the pump.
2. Remove the pump cover (usually on the latches).
3. Remove the old membrane and install a new one (you can order on AliExpress by art. MJTD01YL pump diaphragm).

⚠️ Note: In dispensers with contactless charging (for example, Viomi) V-SOAP02) Do not use metal tools for disassembly – they can damage the coil of wireless charging located at the bottom of the case.

Dispenser Assembly: How to Avoid Mistakes

Reverse assembly often raises more questions than disassembly, to avoid problems:

1. Check the seals: silicone gaskets should lie flat, without distortions.
2. Connect the plumes: make sure the contact card and sensor match.
3. Tighten the screws evenly: do not clamping the case, so as not to deform the plastic.
4. Test before final assembly: temporarily assemble the body and check the sensor and pump.

If the dispenser does not turn on after assembly, check:

• 🔋 Polarity of batteries.
• 🔌 Connection of plumes (especially if you disassemble the fee).
• 🛠️ Integrity of contacts on the board (possibly the wire broke off during assembly).

In models with a touch button (for example, Viomi) V-SOAP01) You may need to reset after assembly. Hold the power button. 10-15 seconds until the indicator flashes three times.

💡

If after assembly the dispenser works unstable (for example, pumps soap jerks), disassemble it again and check the tightness of the connection of the tube with the pump - perhaps there sucks air.

When repairs are not feasible: alternatives and upgrades

If a Xiaomi dispenser breaks down seriously (for example, a board burns down or a body cracks), repairs can cost more than buying a new one.

• 🆕 Updated model: for example, Viomi V-SOAP02 wireless charging and enlarged tank.
• 🔄 Used dispenser: on Avito or Yule often sell working devices for 30-50% cost.
• ♻️ Alternative brands: Hokeki, Secura or Simplehuman offer dispensers with similar features.

When choosing a new device, pay attention to:

• 🔋 Type of power: batteries, USB wirelessly.
• 💧 The volume of the tank: from 250 ml (for home) to 1000 ml (for office).
• 🤖 Additional features: lighting, dosage adjustment, compatibility with Mi Home.

If you are attached to the Xiaomi ecosystem, follow the updates of the line – the brand regularly releases new versions of dispensers with improved tightness and energy efficiency.
