Yes -> check-1: Continue with the matching parts and the checks below. No -> service: Stop for a damaged charger, burning smell, liquid exposure, a swollen or leaking battery, broken catches or an obstruction you cannot safely reach. Contact Dyson and keep the battery sealed. Not sure -> prepared: Save your observations and compare the matching manual before continuing. check-1: Which charging pattern did you observe? Blue lights, or all lights off -> check-2: Distinguish progression from the fully charged state below. A flashing red light, with or without flashing blue -> service: Flashing red indicates a battery fault; flashing red with flashing blue indicates a charger fault in this manual. Contact Dyson. Not sure -> prepared: Compare the charging diagram with the machine stopped. check-2: Is the specified charger intact and the machine dry, cool and free of battery damage? Yes -> steps: Observe charging only with the machine closed and in the stated indoor conditions. No -> service: Stop charging and contact Dyson about damage or unsafe symptoms. Not sure -> prepared: Save your observations and compare the matching manual before continuing. CARE STEPS (only when the route reaches steps) [ ] 1. Separate charging from use Record that the pattern was seen while the charger was connected. The charging and during-use diagrams assign different meanings to blue lights. Look for: If it occurred while using the vacuum, switch to Read lights during use. Source: dyson-v8-manual, p11 Diagnostics – lights during charging; p12 Charging and storage; Battery safety instructions [ ] 2. Inspect the disconnected charger With the charger unplugged, inspect its cable and housing externally. Keep the battery sealed. A damaged cable, unusual smell, leakage or distortion ends the task. Look for: Only the correct undamaged Dyson-specified charger is eligible for the next step. Source: dyson-v8-manual, p11 Diagnostics – lights during charging; p12 Charging and storage; Battery safety instructions [ ] 3. Connect in a dry indoor place Use the specified charger with the machine fully assembled, dry and cool. After a full discharge, let it cool for a few minutes before charging. Look for: The cable is not stretched or trapped and the machine is away from heat and moisture. Source: dyson-v8-manual, pp2–3 Important safety instructions; p11 Looking after your Dyson machine; p12 Charging and storage [ ] 4. Identify the exact pattern One flashing blue means charging from low; one solid plus one flashing blue means medium; two solid plus one flashing blue means nearly full. All lights off is the manual’s fully charged display in the charging context. Look for: A dark display alone, without charge history, does not establish a working charger. Source: dyson-v8-manual, p11 Diagnostics – lights during charging; p12 Charging and storage; Battery safety instructions [ ] 5. Record progress or a concern Observe the normal charge sequence without opening the machine. Save the later pattern. Stop and contact Dyson for a red pattern or persistent unfamiliar behavior; do not infer which part to buy from silence alone. Look for: Normal progression, full indication or an unresolved concern is the useful result. Source: dyson-v8-manual, p11 Diagnostics – lights during charging; p12 Charging and storage; Battery safety instructions OBSERVATIONS Observed context (required): ____________________ Choices: Charger connected Initial charging indication (required): ____________________ Choices: One flashing blue / One solid and one flashing blue / Two solid and one flashing blue / All lights off Later observation (required): ____________________ Choices: Normal blue progression / Normal sequence reached all lights off / Still unclear; contact Dyson [service required] / Red fault appeared; stopped and contact Dyson [service required] RESULT CHECKS [ ] The charging context and light pattern are recorded from the correct manual diagram. [ ] Charge progression is understood, or an unresolved/fault indication is recorded for support; no battery or charger was opened. NEXT CARE The charging light pattern is unfamiliar or charging seems incomplete. As needed for this condition.
