Ok, so your electric diffuser as stopped working, yet its not that old? was a question from my neighbour this morning whilst on our walk. The answer is quite simple: Notice that wee sensor in the bottom of the diffuser (pic attached), that can sometimes get blocked with the base note essential oils (as my neighbour loves using the uplifting soothing synergy – with ylang ylang). I discovered that by filling up the diffuser with very hot water (around 40C), turning on the diffuser, it will clean the wee sensor and clean the components running through the machine, and BOOM, away she goes again….so there you go…breathe more life into your diffusers by doing the above. BTW, we do sell these too!
