Xiaomi hair dryers are popular devices that combine affordable prices, modern design and good functionality. However, like any technology, they can break down: the heat stops working, the air flow weakens or there are extraneous noises. In most cases, repair is possible on their own, but you need to properly disassemble the case without damaging the internal components.
In this article, we will go into detail about the process of dismantling the Xiaomi hair dryer (including Supoon, Dreame and others), tell you what tools you will need, and point out critical points that are often overlooked, and learn how to avoid typical mistakes and not lose the warranty if it is still valid.
Before you start, consider that disassembly of the hair dryer is an interference with the design, which can lead to loss of warranty or irreparable damage if you act carelessly. If you are not sure of your abilities, you should contact the service center. But if you decide to deal with it yourself, follow the instructions carefully.
What Xiaomi hair dryers can be disassembled independently
Most Xiaomi hair dryers have similar designs, but there are nuances depending on the model. Here is a list of devices for which this instruction is suitable:
- 🔹 Xiaomi Supoon MF501 — Classic model with 1600 W and two heating modes.
- 🔹 Xiaomi Dreame HF11 — more advanced version with ionic function and three-stage temperature control.
- 🔹 Xiaomi Mi Home Hair Dryer – a smart hairdryer with app support and several speed modes.
- 🔹 Xiaomi Viomi V-FH01 — model with a ceramic heating element and low noise level.
If you have a different model, check its design for hidden latches or custom mounts, for example, some Dreame hair dryers have additional screws under stickers or rubber legs.
Also, consider that Xiaomi hair dryers of recent years (2022-2026) may have adhesive joints instead of screws – this makes disassembly difficult, but does not make it impossible, in which case you will need a plastic mediator or a special blade to carefully separate parts of the case.
Necessary tools for disassembly
To disassemble the Xiaomi hair dryer, you will need a minimal set of tools. Do not use improvised tools (knives, screwdrivers are not in size) - this can damage the plastic or leave scratches.
Here's the full list:
- 🔧 Cross screwdriver (usually) PH0 or PH1) — hull-screw.
- 🔧 The slender (slender) is a slender (slender) sleeve.
- 🔧 Plastic mediator or spatula - to separate parts of the body without scratches.
- 🔧 Tweezers – for extraction of small parts (wires, contacts).
- 🔧 Multimeter (optional) – to check the chains and heating element.
- 🔧 Silicone mat or soft fabric - so as not to scratch the body during disassembly.
If your hair dryer model uses propellers with a non-standard head (for example, Torx or trigger), you will need a corresponding screwdriver.
⚠️ Warning: Do not use metal tools to separate plastic parts of the case, this can lead to chipping. If the latch does not respond, try to heat the case slightly with a hairdryer (no higher than 60).°C) to make the plastic more elastic.

Step-by-step instructions for dismantling the Xiaomi hair dryer
Now, let's get to the process. The Xiaomi hair dryer is usually taken 20 to 40 minutes to disassemble, if you're careful. Follow the instructions Step-by-step:
Step 1: Removing the back cover
1. Place the hair dryer on the soft surface with the handle up.
2. Find the screws on the back cover (usually 2-4) that can be hidden under rubber plugs or stickers. Carefully tuck them in with a flat screwdriver.
3. Unscrew all the screws and put them aside (preferably in a separate container, so as not to lose).
4. Take a plastic pickup and walk gently around the perimeter of the lid, splitting the latches. Start at the edge where there are no buttons.
⚠️ Warning: Do not use excessive force - if the lid does not respond, check if all screws are twisted. HF11) There is an additional screw under the decorative air intake grille.
Step 2: Unlock the handle
1. After removing the back cover, you will see the inside of the handle with wires and a control board.
2. Carefully disconnect the wire connectors leading to the buttons and the engine. Remember or photograph their location!
3. If the wires are soldered, do not tear them off - it is better to mark their position with a marker on the board.
4. Now you can separate the handle from the main body, and it's usually attached to 1-2 screws and latches.
Step 3: Access to the engine and heating element
1.In the main body you will see the engine, the heating element (spiral) and the fan.
2.To reach them, you may need to remove the front grille (it is usually attached to the latches).
3. Check the integrity of the spiral - if it has darkened or broken, this is the reason for the lack of heating.
4.To completely disassemble the engine may need to unscrew additional screws on its body.
In the models of Xiaomi Supoon MF501 dreame HF11 The heating element is often attached to the body with two screws from the end, which are easy to miss unless you look at the hair dryer from all sides!
| Disassembly phase | Possible difficulties | Decision |
|---|---|---|
| Removal of the back cover | Latches don't lend themselves. | Use a plastic mediator, slightly heat the body |
| Disconnection of wires | It is unclear which connector to connect when assembly | Take a picture of the starting position |
| Dismantling of the engine | The screws are rusty or boiled | Use it. WD-40 grease |
| Checking of the heating element | The spiral is visually intact, but there is no heating | Call the multimeter on the cliff |
💡
If you find rust on the screws or contacts during disassembly, clean them with alcohol or a special contact fluid, which will prolong the life of the hair dryer after repair.
Typical breakages of Xiaomi hair dryers and how to fix them
If you take apart the dryer, you can diagnose most of the malfunctions, and here are the most common problems and ways to fix them:
- 🔥 It doesn't warm the air, check the integrity of the heating coil. If it's broken, it needs to be replaced. If the coil is intact but there's no heating, the problem could be a fuse or a control board.
- 💨 Weak airflow is most often caused by a clogged air filter or worn-out fan blades. Clean the filter and check if the blades are broken.
- 🔊 Heavy noise or vibration - usually associated with wear on engine bearings.
- ⚡ The dryer doesn't turn on -- check the power cord, the fuse, and the power button. Often the problem is the wire break at the base of the handle.
If you find that the engine is not turning but is being pressed, it is likely that it has burned, in which case it is easier to buy a new engine (you can find them on AliExpress or in service centers) and replace it.
For models Xiaomi Supoon and Dreame typical "weaknesses":
- 🔌 Button contacts – oxidize over time, leading to unstable operation.
- 🌀 Engine bearings – require lubrication once every 1-2 years.
- 🔥 Thermal fuse - can work when overheating and require replacement.
What if after the disassembly the hair dryer began to work worse?
How to collect Xiaomi hair dryer after disassembly
Hair dryer assembly is as important as disassembly, and here are the key points to consider:
- 🔌 Connect all the connectors as they were originally connected, and if you're in doubt, check the photos you took before the demolition.
- 🔧 Twisting all screws, but don't pull them over - plastic can crack.
- 🔍 Check the gaps between the parts of the case, and if the lid doesn't fit tightly, then one of the latches hasn't fallen into place.
- 🧪 Test the dryer before final assembly: connect it to the network and check all modes of operation.
Pay special attention to the O-rings (if you have them in your model) which prevent air from passing the heating element, which can lead to a weak flow or overheating.
If the dryer does not turn on after assembly, check:
- 🔌 Correctness of connecting the network cord to the board.
- 🔘 The power button (it may not be fully inserted).
- 🔋 Availability of power on the board (you can check the multimeter).
⚠️ Warning: If the hair dryer sparkles or smells of a burn after assembly, immediately disconnect it from the mains! this is a sign of a short circuit or improper connection of the heating element.
💡
The most common assembly error is the wrong connection of the tachometer connectors, and if you confuse the polarity, the hair dryer will work in jerks or not at all.
When disassembling the hair dryer Xiaomi is inappropriate
Not all hair dryer breakdowns can be repaired on their own, and in some cases, disassembly can only make the problem worse or make the repairs economically unprofitable.
- 💥 The management fee burned down - its replacement requires soldering work and special skills.
- 🔥 Damaged heating element in the non-collectible housing (in some models, the spiral sealed into a ceramic unit).
- 🛠️ Cracks in the case – if the plastic has burst, it’s easier to buy a new hair dryer than to look for parts.
- ⚡ Electrical problems (sparkling, smell of burning for no apparent reason) – it is life-threatening!
Also consider the cost of parts: For example, a new engine for a hair dryer Xiaomi Supoon can cost 60-70% of the price of a new device, in which case the repair loses its meaning.
If your hair dryer is still warranty, the dismantling will automatically cancel it, in which case it is better to first contact the official service center Xiaomi - perhaps repairing it will cost less than replacing parts yourself.
Xiaomi hair dryer care tips to avoid breakdowns
To ensure that the hair dryer lasts longer and does not require frequent repairs, follow these recommendations:
- 🧹 Clean the air intake regularly from dust and hair. A clogged filter leads to overheating and engine failure.
- 🌡️ Do not use a dryer at maximum power for longer than 10 minutes – let it cool down to avoid overheating the spiral.
- 💧 Avoid getting moisture inside the case. If the hair dryer is wet, dry it in disassembled form for at least 24 hours.
- 🔌 Do not pull the cord - this can lead to a break in the wires at the base of the handle.
- 🛁 Keep the hair dryer in a dry place by hanging it by the loop rather than throwing it in a box with other items.
If you notice that the hair dryer is making more noise than usual or the body is warming, these are the first signs of wear and tear, in which case, disassemble it for preventive cleaning and lubrication of bearings.
For models with an ionic function (e.g. Dreame) HF11) It's important to monitor the condition of the ion generator. If it stops working, check the contacts on the board - they can oxidize.
