Why does the Xiaomi Handheld Steam Iron make abnormal noise during operation?

If the Xiaomi Handheld Steam Iron makes abnormal noise during operation, please refer to the following information:
  1. When using the dry ironing mode, ironing directly with the soleplate produces no noise. In wet ironing mode, the sound of the water pump is normal;
  2. When there is water in the tank, the pump noise is relatively low, when the tank is empty, the pump runs dry and the noise will be louder. Please refill the water tank in time;
  3. Ensure the water tank is properly installed and filled with enough water;
  4. Using the iron at an extreme tilt or on an unstable surface can increase pump noise. Always operate on a flat, stable surface;
  5. If the noise persists after all checks, it indicates a faulty internal pump or component. Stop using the iron and contact after-sales service for inspection or repair.
