Please make sure to check: 1. The Shimmy Home is on (press the on/off button and wait for the blue light to flash 3 times) 2. Keep your hand within 3 inches of the dispenser and you hear it try to dispense 3. There is sanitizer in the cartridge 4. Take out and reinsert cartridge so both valves have clicked into place If none of those work, please send us an email at hello@getshimmy.com and we'll take it from there!
