How to Fix / Troubleshooting

Safety first: Turn OFF the vacuum and remove the battery pack.

Step 1 – Allow cooling: Let the vacuum rest for at least 30 minutes in a cool, ventilated area.
Step 2 – Clean external vents: Use a soft brush to remove dust from all air intake and exhaust vents on the main body.
Step 3 – Reduce duty cycle: When resuming use, avoid running continuously on max power. Use standard mode for general cleaning and reserve max for short bursts.
Step 4 – Internal cleaning (advanced): If comfortable and out of warranty, carefully open the housing to blow out dust from around the motor and PCB using dry compressed air. Avoid touching components.
Step 5 – Sensor/PCB replacement: If E12 recurs quickly even when cool and clean, the temperature sensor or PCB may be faulty and require replacement.

Warning: Do not block vents with your hand or soft furnishings during use; this can rapidly overheat the unit.

Vacuum beeps and shows E12; unit may start then immediately stop.
