# Troubleshooting Your Expert

Try these steps, in order, if your Expert isn’t diffusing as expected.

## 1. Check the batteries

Replace the batteries if they’re more than 3–4 months old. Higher intensity levels drain batteries faster.

## 2. Check the fragrance level

Keep the bottle at least 20% full. Running the diffuser empty can damage the compressor pump.

## 3. Reset the diffuser

1. Find the pinhole labeled “RESET” on the diffuser.
2. Insert a paperclip or similar object and hold it until you hear a beep, about 3–5 seconds. The diffuser should start diffusing.

## 4. Clean the diffuser

Run isopropyl alcohol through the system for at least 2–3 minutes. Clean once a month, and before switching fragrances. See [How to Program the Expert](/support/expert/how-to-program-the-expert-exo/) for step-by-step instructions.

## 5. Update the app

- Make sure you have the latest version of our app, listed as Phoenicia Essence. See [How to Install the Mobile App](/support/misc/install-our-mobile-app/).
- Log in with the default password **8888**.
