Goods Scene Troubleshooting
Dreame A3 AWD Pro Rain Protection triggers incorrectly or does not trigger
Rain Protection can appear to trigger when it is not raining, or may not activate immediately in light rain.
Issue meaning
What this issue means
Rain Protection can appear to trigger when it is not raining, or may not activate immediately in light rain.
Start here
First checks
Confirm Rain Protection is enabled in Settings. If it triggers when there is no rain, check for water on the LiDAR because the mower can interpret detected water as rain. If it does not trigger in light rain, Dreame notes that the feature waits for rain that is dense and persistent to reduce false triggers.
Inspection
Area to inspect
Rain Protection setting and water present on the LiDAR surface.
Goods Scene guidance
What to do next
Do not diagnose a sensor failure solely because light rain does not trigger the feature immediately. First confirm the setting and the documented rain-detection behavior.
