Maintenance

To prevent residue buildup and extend the machine's lifespan, the dispenser features an anti-clog self-cleaning system.

Press the switch again to exit cleaning mode.

- Regular Cleaning:
Wipe the exterior of the dispenser with a soft, damp cloth. Avoid using abrasive cleaners or submerging the entire unit in water, despite its IPX5 rating, to protect internal components.
Troubleshooting
- Dispenser not working:
Check the battery level on the LED display. If low, recharge the device using the USB-C cable. Ensure the top section is securely twisted onto the reservoir.
- No soap dispensed:
Verify that the reservoir contains enough liquid soap. If the liquid is too thick, it may need to be diluted slightly with water. Activate the self-cleaning mode to clear any potential clogs.
- Inconsistent dispensing volume:
Adjust the dispensing level using the touch control switch on the top of the device. Ensure the sensor area is clear of obstructions.
