A vacuum that will not charge may have a battery, charger, connection or main-body fault. A short runtime is a different symptom from no charging response, so describe exactly what happens.
Simple checks without opening the machine
- Confirm the wall socket works and the correct charger is connected securely.
- Look for visible damage to the charger lead or connector. Stop using damaged equipment.
- Record the charging light pattern or on-screen message and check it against the instructions for your exact model.
- Note how long the vacuum runs in each mode after charging. Avoid relying on a test in maximum-power mode alone.
Model names are not enough for ordering parts
Photograph the model and serial label and the battery fitting. Closely related vacuums can have different batteries or connectors. We check compatibility before recommending a replacement.
Stop if the battery is damaged
Do not charge or use a swollen, leaking, unusually hot or visibly damaged battery. Do not open or rebuild the battery pack. Contact the team for safe handling and transport advice before bringing or posting it.
Bring the charging system
Bring both the vacuum and its charger. Tell us if there is no light at all, a flashing pattern, an intermittent connection, or a full-charge indication followed by a very short run.
Manufacturer reference: Dyson battery care and V8 owner support. Follow the instructions for your own model.
