Possible Causes
Dirty or damaged wheel encoder disk, Faulty wheel encoder sensor, Loose wheel motor harness, Main board encoder input failure
How to Fix / Troubleshooting
Safety first: Turn OFF the robot and flip it over.
- Inspect wheels: Check both drive wheels for free rotation and absence of debris.
- Access encoder area (if visible): Some Hoover models have encoder disks visible near the wheel motors. Use compressed air to blow out dust.
- Check harness: If comfortable removing the bottom cover, verify that the wheel motor connectors are firmly seated on the main PCB.
- Test again: Reassemble, power ON, and run a short cleaning cycle on a clear floor.
- If E17 persists on one side: Replace the affected drive wheel motor assembly (which includes the encoder). If both sides fail, the main control PCB may be at fault.
