Xiaomi liquid soap dispenser: how to open and not break the mechanism

Xiaomi's liquid soap dispensers are popular smart devices that combine minimalist design with functionality. They automatically dispense a serving of detergent, save consumption, and can even sync with a smartphone via the Mi Home app. But what if you need to refill a new gel, clean a tank, or replace batteries? The manufacturer does not always pay attention to detailed disassembly instructions, leaving users bewildered by the airtight case.

In this article, we will discuss all the official and alternative ways to open Xiaomi dispensers, including the Viomi Smart Soap Dispenser, Xiaomi Mijia Automatic Soap Dispenser and their modifications. You will learn how to avoid breaking latches where hidden mounts are located, and what to do if the lid is β€œripped” from dry soap. And also a unique life hack using a construction hair dryer to soften silicone seals, which is not found in standard manuals.

What Xiaomi dispensers are and how they differ

Xiaomi has released several versions of automatic dispensers, and the ways they can be opened can vary dramatically.

  • πŸ”Ή Viomi Smart Soap Dispenser - flagship series with touch control, application support and capacity of 300-400 ml. It has a magnetic cover and hidden latches.

The main difference is the type of mounting of the cover:

  • πŸ”§ Magnetic (Viomi) – require skill so as not to break the fixtures.
  • πŸ”§ Mijia – spins counterclockwise, but often β€œstaysΒ».
  • πŸ”§ Youpin – you need to click on the hidden buttons from the side.

Before you start disassembling, identify your model. To do this, look at the label on the bottom of the device or in the Mi Home app (Devices section β†’ Information). If the model is identifiable, focus on the type of cover (smooth magnetic, threaded or visible grooves).

Preparation for the opening: what you need and how to avoid breakdown

If you disassemble the dispenser incorrectly, you can cause the casing to crack, or the latches to break, or leaks.

  • 🧴 Warm water and soft cloth - to clean the case from dried soap.
  • πŸ”§ Plastic spatula or mediator – to fit the lid without scratching the plastic.
  • πŸ”₯ Hair dryer (optional) - for softening silicone seals (relevant for models with a magnetic cover).
  • πŸ“± Smartphone with Mi Home app – to reset settings if the dispenser is smart.

Important rules:

  1. Turn off the device from power (remove batteries or disconnect) USB-cable).
  2. Do not use force – if the lid does not lend itself, then you have missed the hidden lock.
  3. Work on a flat surface, laying a towel (in case of a spill of liquid).

πŸ’‘

If the dispenser has not been used for a long time and the soap inside is dry, soak the lower part of the body in warm water for 10-15 minutes. This will soften the deposits and make it easier to open.

Step-by-step: how to open the dispenser of liquid soap Xiaomi

So let's look at the algorithms for each model, and if your device isn't specified, you should look at the type of mounting that you have.

1. Magnetic cover models (Viomi Smart Soap Dispenser)

These dispensers have hidden latches around the perimeter that are held by magnets.

  1. Put the dispenser on your side, lid up.
  2. Take a plastic spatula and gently insert it into the gap between the lid and the body on the side (not in front!).
  3. Smoothly lead the shoulder blade around until you hear a click - this means that one latch has disconnected.
  4. Repeat the action from the opposite side. The lid should be easily removed.

If the lid doesn't lend itself:

  • πŸ”₯ Heat the hair dryer of the edge of the cover (temperature 40–50)Β°C) for 30 seconds - this will weaken the silicone seal.
  • 🧲 Apply a stronger magnet to the lid – this will help to β€œpull” the internal fixtures.

Make sure the batteries are removed.|Prepare a plastic spatula|Heat the edges of the cover with a hairdryer (optional)|Start with the side slit, not the front part-->

2. models with a threaded cover (Xiaomi Mijia Automatic)

Here, the lid is unscrewed counterclockwise, but often gets stuck because of the dried soap.

  1. Cover the body with one hand and start turning the lid to the left (counterclockwise).
  2. If the lid does not go, wrap it with a rubber gasket (for example, from a jar) for better grip.
  3. If this does not help, pour hot water (not boiling water!) into the gap between the lid and the case and wait 5 minutes.

Attention! Don't use pliers, they'll scratch the plastic. If the lid doesn't unscrew, it means the thread is ripped off and you'll need to replace the top.

Models with latches (Xiaomi Youpin)

These dispensers have two hidden buttons on their sides to open:

  1. Look at the body from the side - find small protrusions or indentations.
  2. Press them simultaneously with your thumbs up and in.
  3. The lid should be lifted up. You can then pull it off by pulling it up.

If the buttons are not pressed:

  • πŸ” Light up with a flashlight - it's possible the latches are blocked with dried soap.
  • 🧼 Wash the body with alcohol - this will remove sticky deposits.
What to do if the latches break?
If the plastic cap locks break down, you can temporarily attach it with tape or silicone sealant (but this will violate the tightness). For full repair, you will need to replace the top panel - you can order it on AliExpress by the model article (indicated on the label below).

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when disassembling dispensers.

Mistake.Effects of consequencesHow to avoid
Use of metal toolsScratches on the body, chipped plasticUse only plastic shoulder blades or mediators
Use of excessive forceCracks, broken latches.Heat the body with a hair dryer or pour warm water into the slot
Attempting to open from the frontDamage to the infrared sensorAlways start with the side slits.
Ignoring dried soapThe lid is "cracking" dead.Rinse the tank regularly (every 2-3 months)

Critical error: trying to disassemble the dispenser without removing the batteries, which can lead to a short circuit if water gets to the contacts. Always turn off the power before disassembling!

πŸ’‘

If the dispenser lid does not open despite all the efforts, do not try to break it. Contact the Xiaomi service center - in 80% of cases the problem is solved by professional cleaning or replacing the seal.

Cleaning and maintenance after opening

When the lid is finally removed, don't rush to pour the new soap. Do a full cleaning, otherwise the dispenser will quickly clog:

  1. Wash the tank with warm water and soap (no abrasives!). Use vinegar solution (1:1 with water) to remove plaque.
  2. Clean the pump: πŸ’§ For models with a pump: type in a syringe warm water and wash the tube. πŸ”„ For smart dispensers: run a soap supply cycle without a tank (the device will pump water through the system).

Check the battery compartment.

Grease the seals

WD-40 Specialist

Attention, don't use this for cleaning.

  • 🚫 Hard brushes – they will damage silicone parts.
  • 🚫 Boiling water - deforms plastic.
  • 🚫 Chlorine-containing products - corrodes seals.

After cleaning, dry all the parts for at least 2 hours. Smart dispensers (Viomi) can be dried with a dryer in cold air mode, directing the flow to the vents from below.

Battery replacement and resetting

If the dispenser stopped responding to the sensor or flashes red, maybe the battery has gone down or there's a firmware failure, and we'll look at both.

1. Battery replacement

Most Xiaomi models use:

  • πŸ”‹ 2 batteries AAA (Mijia Automatic).
  • πŸ”‹ 1 lithium CR2032 (Viomi Smart).

To replace them:

  1. Turn over the dispenser and find a battery compartment (usually closed with a lid on the latch).
  2. Remove old batteries and insert new ones, keeping polarity in mind.
  3. For smart models: After the battery is replaced, you may need to reconnect to the Mi Home (press the reset button for 5 seconds).

2. Resetting settings

If the dispenser is glitching (does not respond to the hand, blinks, gives an error in the application), reset:

  • πŸ“± Through the app: Open Mi Home β†’ select the dispenser β†’ Settings β†’ Remove the device. Then add it again through Add the device.
  • πŸ”§ Hardware reset: Press and hold the button on the body (usually under an infrared sensor) for 10 seconds. The dispenser will flash blue - this means that the settings are reset.

After the reset, you may need to update the firmware.

  1. Connect the dispenser to the Mi Home.
  2. Go to the device settings β†’ Update the firmware.
  3. If the update is not available, check the server region in the application settings (should be China or Global).

FAQ: Answers to Frequent Questions
