← Full guide: Dyson V10 Blue Lights: Decode the Pattern Before Service
Dyson V10 shows three solid blue lights
Three solid blue lights are not an error by themselves; Dyson uses them to indicate a high battery charge level.
Start here
Three solid blue lights are not an error by themselves; Dyson uses them to indicate a high battery charge level.
Check these first
- Pull trigger and observe whether lights are solid or flashing.
- Look for blockage/filter indicators.
- Test without wand/tool if Dyson’s flow permits that diagnostic.
Fix it in this order
- Treat solid blue as battery-level information.
- Follow Dyson blockage/filter symptom flow.
- If the machine still cuts out with no blockage/filter warning, continue power/battery/service diagnosis.
Evidence to keep
- Video of exact light pattern
- Whether blockage/filter light is present
Do not make it harder
- Replacing battery solely because three solid blue lights appear
How you know it is fixed
- Machine runs normally and the light behavior matches normal charge state.
If the obvious fix does not work
- If one blue light flashes instead, the battery needs charging rather than blockage diagnosis.
- If red lights appear, use Dyson’s red-battery fault path.
If this still isn't resolved
- Dyson Support
