Troubleshooting
If you see either a flashing 'E' or a solid 'E' on your purifier’s display, please complete the following steps.
Power
- Unplug the purifier.
- Leave for 10 seconds.
- Ensure the plug is firmly connected to the socket and switched on at the wall then retry.
Temperature range
Ensure the room temperature is above 5°C.
Loop amplifier and filter housing
Look for blockages in the air inlet holes on the filter housing and in the small aperture inside the air loop amplifier. Use a soft brush to remove debris.
Check the filter
- Your filter may need replacing. Check filter life within the app, or for excessive build up of dust within the inlet.
- For more information about replacing the filter, please see 'Replacing the filter unit'.
