Possible Causes
Defective airflow or pressure sensor on main PCB, Sensor wiring harness loose, Dust contamination on sensor port, Firmware misreading sensor values
How to Fix / Troubleshooting
Safety: Power off and remove the battery.
- Clean internal air paths: Ensure cyclone, filters, and vents are clean to avoid false sensor readings.
- Soft reset: Remove the battery for several minutes, then reinstall and test.
- Firmware update (if supported): Some Dreame models can be updated via app or service tool. Check Dreame support for firmware updates that address sensor issues.
If E8 remains, the internal sensor or main control board is likely faulty. Replacement of the main PCB is typically required and should be done by a qualified technician.
