Vacuum shows E13 or a thermometer icon while charging, charging pauses

Safety first: Do not attempt to cool or heat the battery artificially (no freezers, heaters, or direct sunlight).

• Step 1 – Allow cooling or warming: If the vacuum was used heavily, let it rest for 30–60 minutes at room temperature before charging again.
• Step 2 – Move to suitable environment: Charge the vacuum in a room between 10–30°C. Avoid garages or sheds that are very cold or hot.
• Step 3 – Ensure ventilation: Make sure the AEG charging stand is not covered by cloth or placed in a confined cabinet. Allow air to circulate around the unit.
• Step 4 – Retry charging: Place the vacuum back on the stand. If E13 clears and charging resumes, the issue was temperature-related.
• Step 5 – Persistent E13 at normal room temperature: The battery temperature sensor (NTC) or BMS may be faulty. The battery pack will need professional replacement.
