Hoover washer shows E09 and will not run motor; often appears on models with inverter or brushless motors.

Safety first: Unplug the machine. Inverter circuits store high voltage—do not touch capacitors or power modules unless fully discharged and you are qualified.

• 1. Check drum and mechanicals: Ensure the drum turns freely by hand. Mechanical jams can trigger inverter faults.
• 2. Inspect motor harness: Access the motor and check the multi-core cable to the inverter module for damage or loose plugs.
• 3. Visual check of inverter module: On many Hoover models, the inverter is a separate module near the motor. Look for burn marks or cracked components. Do not attempt board-level repair unless trained.
• 4. Power reset: Leave the machine unplugged for 15–20 minutes to allow capacitors to discharge, then reconnect and test. If E09 reappears, the module or motor is likely defective.
• 5. Replacement: Typically, the fix is to replace the complete inverter module and, if indicated by tests, the motor assembly with Hoover-approved parts. This is best done by a service technician.
