Possible Causes
Failed main control PCB, Damaged power switch circuit, Internal short from liquid ingress, Blown surface-mount fuse on PCB
How to Fix / Troubleshooting
Safety first: Remove the battery pack and disconnect the charger.
Basic checks:
- Inspect the vacuum body for signs of impact damage or liquid spills. If the unit has been dropped or exposed to water, internal damage is likely.
- Check that the battery is fully charged and that its contacts are clean and undamaged.
- Try a different compatible battery if available to rule out battery failure.
- If E9 appears with any battery and the unit will not run, the main control PCB or internal wiring is likely faulty.
- Disassembly of the main body to access the PCB involves dealing with high-current circuits and should be done only by a qualified technician. In most cases, the main body assembly or PCB is replaced.
Warning: Do not continue attempting to power on a unit that shows E9 after liquid damage; this can pose a shock or fire risk.
