Possible Causes
Corrupted firmware on main PCB, Faulty communication between main PCB and handle PCB, Electrostatic discharge damage, Power interruption during firmware update (if supported)
How to Fix / Troubleshooting
Safety first: Remove the battery and wait 1–2 minutes before attempting resets.
- 1. Hard reset: With the battery removed, press and hold the power button for 15–20 seconds. Reinsert the battery and try again.
- 2. Remove accessories: Detach the wand and motorised head, then test the main body alone. This isolates external components from the control system.
- 3. Check for moisture or damage: Open the housing (if possible) and inspect the main PCB for visible damage, burn marks, or corrosion.
- 4. Firmware update (if available): Some newer Beko cordless models may support firmware updates via service tools only. Contact Beko support or a service centre to check if a firmware reflash is possible.
- 5. PCB replacement: Persistent E18 usually requires replacement of the main control PCB. This is a technician-level repair due to wiring complexity and safety considerations.
