Touch dispenser for liquid soap Xiaomi: how to fill the cartridge without errors

Touch soap dispensers from Xiaomi have become a popular solution for bathrooms and kitchens thanks to a combination of stylish design, automation and consumable savings. However, many users face difficulties when first filling the cartridge - wrong actions can lead to leaks, locking the mechanism or even breaking the device. In this article, we will discuss all the steps of the process, from choosing the right liquid to sealing the tank, taking into account the features of different models of Xiaomi dispensers (for example, Mijia Smart Liquid Dispenser or Viomi). V1).

Xiaomi cartridges have a translucent body and a valve system that requires careful handling. If you've used mechanical dispensers before, the touch model may seem more complicated, but in practice, the refueling process takes no more than 5 minutes with the right approach. We'll also reveal the hidden nuances that are not written about in the official instructions: how to avoid traffic jams, what you can not refuel the device and how to extend the life of the cartridge.

What liquid can be used in the dispenser Xiaomi

Not all detergents are compatible with automatic dispensers. The manufacturer recommends liquids with a viscosity of 1000–3,000 mPa·s (close to a regular liquid soap or shower gel); too thick formulations (such as cream soap) can clog the pump, and excessively liquid (such as diluted shampoo) can flow through the valves.

The best options are:

• 🧼 PH neutral liquid soap (such as Dove, Nivea or Ecover) Avoid abrasive particle products.
• 🧴 Shower gel without oils and large bubbles. Shake the bottle before filling to prevent dissection.
• 🧽 Cleaning liquid for washing dishes (for example, Fairy or AOS), but only in diluted form (1:1 with water).
• 🩹 Alcohol-based antiseptic gels (up to 70% alcohol) More concentrated solutions can damage seals.

It is strictly prohibited:

• ❌ Means with large granules (scrabs, peels).
• ❌ Oil-based liquids (e.g., liquid soap with argan oil).
• ❌ Bleachers and harsh chemicals (e.g. Domestos).
• ❌ Homemade soap solutions with unstable consistency.

⚠️ Warning: If you use a fragrance liquid, leave the cartridge open for 10-15 minutes after refueling to avoid vapor buildup inside the case.

Preparation for fueling: what will be needed

Before starting the process, make sure you have:

• 🔧 Clean dry cloth (microfibre or paper towel) to remove spilled liquid.
• 💧 Small diameter funnel (you can use the top of a plastic bottle with a cut neck).
• 🧴 The container with the liquid you plan to fill (the volume of the cartridge is usually 300-500 ml).
• 🔍 Toothpick or thin stick to clean the valve (when refueling).

Also prepare the workplace:

• Place the dispenser on a flat, stable surface (such as a table) to avoid tipping over.
• If the cartridge has already been used, rinse it with warm water and dry it for at least 2 hours.
• Disconnect the dispenser from power (if the model is powered by a network or battery).

Important: Do not fill the cartridge in direct sunlight - some liquids (such as those with citric acid) may become cloudy or change the consistency.

💡

If you're filling the dispenser for the first time, take a picture of the location of the sealing rings and valves before disassembly, which will help you to properly assemble the cartridge back.

Step-by-step instructions for filling the cartridge

Refueling process for models with removable upper hatch (for example, Mijia Smart Liquid Dispenser) and a single body (for example, Viomi) V1). We will look at the universal algorithm:

1. Removal of the cartridge cover: Most models have latched caps. Press the side projections (usually marked with a symbol) PUSH) And if the lid doesn't lend itself, don't force it, make sure it's blocked by the remaining fluid inside.
2. Removing the internal tank: Carefully remove the plastic tank from the housing.In some models, it is attached to the pump - do not pull sharply so as not to damage the silicone tubes.
3. Valve cleaning (refill): If the cartridge has been used before, wash the valve with warm water and dry it. Make sure it does not have dried soap residues that can block the flow of fluid.
4. Refilling fluid: Use a funnel to pour liquid into the tank. Fill it not to the edges - leave 1-1.5 cm of free space to prevent overflow when the pump is running. Optimal level: ~80% of the volume.
5. Removing air traffic: After refueling, tilt the tank slightly in different directions so that the air bubbles rise up. This will prevent the pump from starting dry, which can lead to failure.
6. Cartridge assembly: Set the tank back into the body, making sure the silicone tube of the pump isn't twisted. Close the lid before you click - this is a signal that the locks are in place.

Critical error: If the dispenser gives off the liquid in jerks after refueling or doesn't work at all, most likely there is air left in the pump tube. To fix the problem, turn off the device, remove the cartridge, slightly press the tank to squeeze air through the valve, then repeat the assembly.

Frequent Mistakes and How to Avoid Them

Even when following the instructions, users often make mistakes that lead to improper operation of the dispenser.

One of the most insidious problems is the crystallization of soap in the valve, which happens when the dispenser has been left unused for a long time or has been filled with a high-salt product.

• 🔄 Once a month, wash the cartridge with warm water, even if the liquid is not yet out.
• 🌡️ Keep the dispenser at a temperature of 10–30°C – at lower temperatures, some gels thicken.
• ⏳ Do not leave liquid in the cartridge for longer than 3 months – over time it may dissipate.

⚠️ Note: If the dispenser is connected to the Mi Home app, you may need to reset the flow meter after refueling. → Data resetting.

How to extend the life of the cartridge

Xiaomi dispensers cartridges are designed for 200-300 refueling cycles, but if used improperly, this period is reduced by 2-3 times.

• 🧼 Use only certified liquids – harsh chemicals corrode silicone seals.
• 🔄 Wash the cartridge after changing the type of liquid (for example, when switching from soap to antiseptic).
• 🌞 Avoid direct sunlight – UV radiation makes plastics brittle.
• 🔋 Disconnect the dispenser from the network for prolonged downtime (more than 2 weeks).

If you notice that the pump is noisier or the fluid is late, it's a sign of wear and tear on the silicone membrane.

1. Buy a repair kit (sold in official Xiaomi stores).
2. Follow the video instructions for replacing the membrane (link at the end of the article).
3. If repair is not possible, replace the cartridge entirely - its cost usually does not exceed 30% of the price of a new dispenser.

Alternative refuelling methods

If the standard method for some reason is not suitable, you can use alternative options:

1. Refueling without cartridge removal

Some models (e.g. Viomi) V1 Pro) allow liquid to be added through a special opening on the top panel:

1. Remove the protective cover of the hole (usually marked with a drop pictogram).
2. Use a funnel with a narrow nose so that the liquid does not spill past.
3. Fill the tank slowly to avoid bubbles.

2.Use of original pre-filling cartridges

Xiaomi's official stores sell tucked cartridges with liquid soap or antiseptic.

• ✅ Guaranteed compatibility with the dispenser.
• ✅ Optimal viscosity of liquid.
• ✅ Pressurized packaging that excludes leakage.

The disadvantage is the high cost (in 2-3 times more expensive than self-fueling).

• DJT11LM-01 — pH-neutral soap.
• DJT11LM-02 — antibacterial.

3. Adaptation of the cartridge to other liquids

If you want to use a dispenser for non-standard liquids (for example, hand spice or skin care fluid), you will have to modify the cartridge:

• Remove the standard valve and replace it with a silicone nipple from the medical system.
• Use liquids with a viscosity of no more than 1500 mPa·s.
• Wash the cartridge after each use to avoid blockages.

⚠️ Warning: Cartridge modification voids the warranty on the dispenser. If the device is connected to the Mi Home ecosystem, non-standard fluids can cause sensor errors.

Maintenance and cleaning of the dispenser

Regular cleaning of the dispenser prolongs its life and prevents the reproduction of bacteria.

• 🧽 Weekly: Wipe the touchpad and body with a wet wipe.
• 🔄 Once a month: Rinse the cartridge and pump (see instructions below).
• 🛠️ Every 6 months: Check the condition of seals and silicone tubes.

Step-by-step cleaning of the pump:

1. Turn off the dispenser from power.
2. Remove the cartridge and drain the remaining liquid.
3. Pour warm water into the tank with the addition of vinegar (1:10) and turn the dispenser into the “washing” mode (if any).
4. Pump the pump 3-5 times, then drain the solution.
5. Wash the cartridge with clean water and dry for at least 2 hours.

For models with UV lamps (e.g. Viomi) V1 Pro) additionally:

• Once every 3 months, wipe the lamp with alcohol to remove plaque.
• Do not turn on UV disinfection without liquid in the cartridge – this reduces the life of the lamp.

💡

Never use abrasive cleaning products or hard brushes – they damage the touchpad and seals.

Cartridge repair and replacement

If the cartridge fails, it can be repaired or replaced.

1. Repair of the cartridge

Most often, they break:

• 🔧 Silicone pump membrane - a sign: the pump is buzzing, but no liquid is supplied.
• 🔄 The supply valve is a sign: the liquid flows spontaneously.
• 🔌 O-ring - a sign: leaks on the sides of the cartridge.

For membrane repair:

1. Disassemble the cartridge by removing the top cover and removing the pump.
2. Carefully remove the old membrane (it is attached to the latches).
3. Install a new membrane (Article for Mijia — XMD-001).
