Possible Causes

Worn main motor drawing excessive current at high speed, Faulty motor driver MOSFETs on PCB, Partially blocked airflow causing high load, Weak battery unable to supply high current

How to Fix / Troubleshooting

Safety first: Remove the battery pack before cleaning or disassembling.

Steps to narrow down the cause:

  • 1. Clean filters and airflow: Ensure all filters are clean and the airflow path is clear to reduce load on the motor.
  • 2. Test with fully charged battery: Charge the battery to 100% and immediately test high-power mode. Weak batteries often cause high-mode shutdowns.
  • 3. Try a second battery (if available): If a different Hoover Candy battery allows high-power operation, the original battery is failing.
  • 4. Listen for motor noise: If the motor sounds rough, whines, or smells hot when attempting high power, the motor windings or bearings may be failing.

Repair recommendation: Persistent E10 behavior with good airflow and a known-good battery usually indicates a failing motor or motor driver circuit. Replacement of the main motor assembly and/or control PCB should be performed by a service technician.
