Possible Causes
Partially clogged filter causing high load, Weak battery unable to supply turbo current, Motor windings degraded, Control PCB current limit too sensitive due to damage
How to Fix / Troubleshooting
Safety first: Remove the battery before cleaning.
- Clean all filters and air paths: Follow the full filter and cyclone cleaning steps as for airflow restriction. Even partial blockage can cause high current draw in turbo mode.
- Use a fully charged battery: Install a freshly charged, genuine Makita battery of the correct capacity. Low-voltage sag can trigger overcurrent protection.
- Test on low then high: With clean filters and a good battery, run the vacuum on low for 30 seconds, then switch to high. If it still shuts down with E9, internal motor or PCB issues are likely.
- Service recommendation: Persistent E9 in turbo mode usually indicates motor wear or a failing control board. Continued use may cause complete failure; have the motor housing assembly tested and replaced if necessary.
