Possible Causes
Weak battery unable to supply high current, Failing main PCB power MOSFETs, Shorted motor windings at high load, High resistance at battery contacts
How to Fix / Troubleshooting
Safety first: Remove the battery before inspecting contacts. Do not open the battery pack.
- Test on low vs high: Confirm the vacuum runs normally on low/medium but fails only on high. This points to a high‑current issue.
- Check battery health: Fully charge the battery, then test run time on low. If run time is very short, the battery pack is likely degraded and may sag in voltage on high mode.
- Inspect contacts: Clean the battery and vacuum contacts with a dry cloth. Ensure the battery locks firmly into place.
- Try a second battery (if available): If a known‑good Insignia battery works fine on high, replace the original battery pack.
- Board/motor issues: If E6 occurs with multiple good batteries, the main control PCB or motor may be failing. These require disassembly of the main body and should be handled by a qualified technician.
