We usually recommend that you make sure all cartridges are properly installed:
1. Unplug your Hero
2. Open it with safety key
3. Make sure all cartridges are properly inserted. You should hear a click once a cartridge is properly installed.
Are you getting missing cart error even though all carts are installed?
We want to resolve your problem as quickly as possible, so you can get the most out of your Hero membership. If we determine that it’s a mechanical or technical performance issue with the dispenser, then that would warrant a replacement. Please send us a video that clearly captures sound to support@herohealth.com. Member Experience is here for you 24/7! Call us at 1-855-855-9962 or chat at herohealth.com.
