Operating Instructions
Dispensing Soap
To dispense soap, simply place your hand under the sensor nozzle. The sensor will detect your hand and automatically dispense a precise amount of soap.
- Variable Dispense: For a small amount of soap, position your hand close to the sensor. For a larger amount, move your hand slightly farther away. The sensor adjusts the volume based on distance.
- The flexible silicone valve will snap shut after dispensing to prevent any drips.

Troubleshooting
If you encounter issues with your simplehuman sensor pump, please refer to the common problems and solutions below:
| Problem | Possible Cause | Solution |
|---|---|---|
| Dispenser not working / No soap dispensed | Low battery; Clogged pump; Incorrect soap consistency; Sensor obstruction. | Charge the unit fully. Ensure the soap reservoir is full. If using thick soap, dilute slightly with water. Clean the sensor area and nozzle. |
