What to do if self-cleaning fails on Dreame H12 Core?
- EEthan DavisAug 31, 2025
If the self-cleaning function fails on your Dreame Vacuum Cleaner, consider these potential solutions: * Remove the brush roller cover to check and clean the brush roller if it's jammed by large debris. * Ensure the appliance is properly placed on the charging base and is charging before enabling self-cleaning. * Note that self-cleaning can only be enabled when the battery level is above 20% and the appliance is charging. * Re-install or empty the Used Water Tank if it's not installed correctly or is full. * Fill or re-install the Clean Water Tank if it's not installed correctly or the water level is insufficient.
