Xiaomi’s electric kettles are not only a stylish kitchen gadget, but also a complex device with electronic controls, a thermostat and a safety system, which can be disassembled to clean scale in hard-to-reach places, replace the thermal power plant, repair the switch or diagnose malfunctions. However, the design of the Mi Smart Kettle, Viomi and other models of the brand has its own characteristics: hidden latches, non-standard screws and the risk of damage to electronic components.
In this article, we will take a detailed look at the disassembly process, taking into account all the nuances, what tools will be required, how to avoid typical errors (for example, damage to the O-ring or a break in the wires of the temperature sensor), and what to do if the kettle does not turn on after assembly.
⚠️ Warning: Disassembling the kettle will void the manufacturer's warranty. If your Mi Smart Kettle Pro or other model is still in warranty service, contact Xiaomi Service Center.
Preparation for disassembly: tools and security measures
Before you start, make sure you have everything you need. Most Xiaomi kettles are sorted out using a standard toolkit, but some models (like the Viomi). V-KETTLE300) You may need specialized screwdrivers.
Minimum set of tools:
- 🔧 Cross screwdriver (PH0 or PH1) — corpus.
- 🔧 A flat screwdriver with a thin sting - for slapping latches.
- 🔧 Plastic blades or mediators - so as not to scratch the body.
- 📸 Smartphone for photographing the dismantling stages (useful when assembly!).
- 🧲 Magnetic mat or screw container – to avoid losing small details.
Security measures:
- ⚡ Disconnect the kettle from the mains 10-15 minutes before disassembly (capacitors can retain charge).
- 💧 Completely drain the water and dry the appliance - moisture inside can cause a short circuit.
- 🧤 Use rubber gloves if you plan to work with TENG or contacts.
⚠️ Note: If your Xiaomi kettle has a wireless base (like the Mi Smart Kettle Pro), do not try to disassemble it yourself - inside high-voltage contacts that require a professional approach).
Disassembly scheme: step-by-step instructions with photo
The disassembly process can be divided into 3 stages: removal of the bottom cover, disconnection of the electronic unit and access to the TEN. Let's consider each of them in detail.
Step 1: Removal of the bottom cover
On most Xiaomi models, the bottom cover is attached to 3-4 screws (sometimes under rubber legs) and latches. Carefully tuck the lid with a plastic blade, starting from the junction with the body. If the lid does not lend itself, check if all screws are twisted - often one of them is hidden under a serial number sticker.
Typical locations of screws:
- 🔩 Under rubber legs (2-3 pcs.).
- 🔩 Under a barcode sticker (1 pct.).
- 🔩 In the depressions near the power connector (1 pc.).
☑️ Preparation for lid removal
⚠️ Attention: On touch-controlled models (such as the Mi Smart Kettle Pro), there may be a plume under the cover connecting the control board to the display. Don't pull the lid sharply - first unplug the plume!
Step 2: Disconnection of the electronic unit
Once you remove the lid, you'll see an electronic module with a control board, a thermal sensor, and TEN contacts. Most Xiaomi kettles have a module attached to 2-3 screws and locks. Gently disconnect the connectors (you can put them in a flat screwdriver) and remove the board.
What can be damaged at this stage:
- 🔌 Thermometers are thin wires that go to the TEN, and if you tear them off, the kettle won't tell the temperature of the water.
- 📶 antenna Wi-Fi/Bluetooth (It can be glued to the body.
- ⚡ Food Contacts – If you bend them, the kettle will not turn on.

Stage 3: Access to TEN and internal parts
The TENG in Xiaomi kettles is usually screwed to the bottom of the case with 3-4 screws.
- Unscrew the mounting screws.
- Carefully lift the TENG, do not pull the wires!
- Disconnect the power terminals (remember their location or take pictures).
In the kettles of Viomi V-KETTLE300 The TEN can be soldered to the body - in this case, a soldering iron and solder will be required to replace it.
| Model kettle | Type of TEN attachment | Features of disassembly |
|---|---|---|
| Mi Smart Kettle (without display) | Screws (3-4 units) | Simple design, TENG is removed without a soldering iron. |
| Mi Smart Kettle Pro | Screws + locks | You need to disconnect the display plume, risk sensor damage. |
| Viomi V-KETTLE300 | The soldering joint | To replace the TEN, you need a soldering iron. Complex electronics. |
Typical malfunctions and their elimination
If you’ve taken apart a Xiaomi kettle for repair, here are the most common problems and ways to solve them:
The teapot shall not be switched on:
- 🔌 Check the fuse on the board (can burn when voltage surges).
- 📱 Smart models (Mi Smart Kettle Pro) may require resetting via the Mi Home app.
- ⚡ Check the food contacts on the base and kettle - they could have oxidized.
2. Does not heat the water:
- 🔥 Burned TEN - Replacement is required (check resistance with multimeter).
- 🌡️ Thermosensor is faulty – the kettle “thinks” that the water is already hot.
- 🔄 Problem with the switching relay on the board (need a soldering iron).
3. Water flows:
- 🛠️ Worn sealing ring between the TEN and the body - replace with a new (you can buy a remap).
- 💧 Cracks in the body - in this case, repair is inappropriate.
💡
If Xiaomi teapot after disassembly began to make strange sounds (hisping, crackling), most likely, the TENG is covered with a thick layer of scale. Clean it with citric acid (2 tablespoons per 1 liter of water, boil for 10 minutes).
Cleaning scale and heat: how to prolong the life of a kettle
One of the main reasons for disassembling the kettle is to clean scale, which reduces the efficiency of heating and can put the TEN out of action. In Xiaomi models with closed TEN (as in the Mi Smart Kettle Pro), scale accumulates not only on the heating element, but also in hard-to-reach cavities.
How to clean the TENS and internal details:
- Remove the TENG (as described above).
- Immerse it in a solution of citric acid (100 g per 1 liter of water) for 1-2 hours.
- Clean with a soft brush or sponge (do not use metal scrapers!).
- Wash the body of the kettle under running water, paying attention to the places of fastening of the TEN.
⚠️ Warning: Don't use vinegar to clean Xiaomi kettles - it can damage rubber seals and plastic parts.Citric acid is safer and more effective.
Scale prevention:
- 💧 Use filtered or bottled water.
- 🔄 Regularly (every 1-2 months) clean with citric acid.
- 🌡️ Do not re-boil the water – this accelerates the formation of scale.
The assembly of the kettle: how to avoid mistakes
Making a Xiaomi kettle after a breakup is harder than disassembling, and the rule of thumb is to follow the reverse order and check each step.
O-ring:
- Before installing the TEN, apply a thin layer of silicone lubricant (food!) to the ring.
- Make sure the ring is flat, without any distortion.
Electronic module:
- Check that all connectors are tightly connected, but without effort.
- Smart models (Mi Smart Kettle Pro) may require calibration after assembly (reset in the Mi Home app).
Cover and body:
- Twisting the screws cross-cross to avoid distortion.
- Before final assembly, check the operation of the on button and indicators.
(1) Correct connection of the thermal sensor.
(2) Integrity of the safety lock on the board.
(3) Base and kettle feeding contacts.
In 90% of cases, the problem lies in one of these points.-->
What to do if the kettle does not work after disassembly
If after assembly, the Xiaomi kettle refuses to turn on or does not work correctly, do not panic.
1. Check the power:
- ⚡ Make sure the socket is working (plug in another appliance).
- 🔌 Examine the cord and fork for damage.
- 📱 Smart models: check Wi-Fi connection in Mi Home app.
Diagnostics of the electronic unit:
- 🔍 Check the safety lock on the board (should be whole).
- 📊 Measure the resistance of the TEN with a multimeter (should be 20-50 ohms).
- 🌡️ Call the temperature sensor (resistance should change when heated).
Mechanical failures:
- 🛠️ Make sure that the TENS are tightly pressed to the body (otherwise the contacts will not close).
- 🔄 Check if the switch button is skewed.
⚠️ Warning: If you find burnt-out elements on the board (blackened resistors, bloated capacitors), self-repair can be dangerous.
