How to Fix / Troubleshooting
Safety first: Remove the battery pack before inspecting the handle or control panel.
- Step 1 – Check for physical damage: Inspect the power and mode buttons on the Jimmy handle. If a button is stuck, gently work it free. Do not use sharp tools that can puncture the rubber membrane.
- Step 2 – Dry out moisture: If the control area was exposed to moisture, leave the vacuum in a warm, dry room for 24–48 hours with the battery removed. Do not use heat guns or hair dryers.
- Step 3 – Test again: Reinstall the battery and check if buttons respond. Try pressing firmly but not excessively.
- Step 4 – Internal inspection (advanced): If comfortable, open the handle shell and inspect the keypad flex cable connection to the main PCB. Reseat the connector.
- Step 5 – Replace parts: If E8 persists, replace the handle keypad assembly or the main control PCB. This is typically a technician-level repair.
