Vacuum turns on but shuts off after a few seconds with no error code, especially on high power

Safety first: Remove the battery if it feels hot to the touch and allow it to cool.

• 1. Reduce load: Clean all filters and check for blockages in the floorhead and wand. A restricted airflow increases load on the battery and motor.
• 2. Test on lower power: Run the vacuum on a low or medium setting. If it runs significantly longer, the battery may no longer support high-power operation.
• 3. Fully charge and retest: Charge the battery to 100% and test again. If run time remains very short, the battery is nearing end of life.
• 4. Replace the battery: Purchase a genuine Miele replacement battery pack compatible with your cordless model.
