H2EO® Warranty Service and Repair

There are very few service needs with H2EO® Diffusers if they are properly used and maintained.  Most problems reported are the result of water/essential oil spillage in the workings of the diffuser.  The main causes for this are: overfilling the diffuser; moving or bumping it with water in the bowl; diffusing with the director nozzle broken, upside down, or missing; or positioning the director nozzle so that mist falls onto the diffuser control panel.

To avoid unnecessary service issues, please read the comprehensive USER HANDBOOK, and watch the six-minute DIFFUSER VIDEO that will show you how to set up, use, and easily maintain your diffuser for many years of happy diffusing. 

For help resolving most situations, download H2EO TROUBLESHOOTING TIPS.
