- pH level - should be in the range of 5.5-8.0. Acid or alkaline solutions corrode seals.
- Solid particles, maximum 0.1%, and soap base crumbs or undissolved salt crystals scratch the pump.

Top.-3 Mistakes that spoil Xiaomi’s dispenser
Even a perfectly cooked soap can make a machine fail if you break the rules of operation, and here are the most common mistakes and their consequences:
- Using unfiltered water, chlorine and hardness salts settle on the tubes, narrowing the lumen, and in 2-3 months, the dispenser will start to emit an error. E1 (Solution: Use distilled water or pass tap water through the filter Barrier.
- Hot soap pouring. Temperature above 50.°C deforms the plastic parts of the pump. Symptoms: leaks, unstable dosage. Solution: Cool the mixture to room temperature before pouring.
- Ignoring cleaning: Soapstone and bacteria accumulate in the tank, causing an error E3 (Solution: Wash the dispenser 1 time per month with vinegar solution (1:10 with water).
How to know if the dispenser is broken because of soap:
- 🔴 It's on display. E2 or E3.
- 🔴 Soap is given out in jerks or drips by itself.
