Pump needs to be reset:

1. Press and hold the power button down for 5 seconds.
2. Wipe the sensor lens clean. We recommend using rubbing alcohol and a microfiber cloth to do so.
3. Press the power button for 1 second to turn the unit on.
4. Completely cover the sensor window and tap the power button quickly 3 times (within 2 seconds). Note that this will make the pump run continuously until the sensor window is uncovered.

Sensor pump may be clogged. Completely cover the sensor window and tap the power button quickly 3 times (within 2 seconds). Note that this will make the pump run continuously until the sensor window is uncovered.

Flashing red light indicates the battery is low and batteries need to be replaced.

1. Ensure that you do not move your hand away previous to the dispensing cycle.
2. Thinner soaps like Dr. Bronner's can cause your pump to drip.
