Possible Causes

Moisture ingress into handle electronics, Shorted motor terminals, Damaged main control PCB, Corroded internal connectors

How to Fix / Troubleshooting

Safety first: Immediately switch OFF, remove the battery, and do not attempt to use the vacuum if liquid has been sucked up. Risk of electric shock and further damage.

  • Drying period: If minor moisture exposure is suspected, remove all detachable parts (bin, filters, wand, nozzle) and allow the main body to air‑dry in a warm, dry place for at least 48 hours. Do not use heat sources like hairdryers.
  • Inspect for visible corrosion: Check external terminals and contacts for green/white corrosion. Do not scrape aggressively.
  • Do not bypass safety: Do not attempt to bridge fuses or short contacts to clear the error.

If E10 persists after thorough drying, internal damage to the main PCB or motor is likely. This repair involves opening the main housing and should be carried out by a qualified service technician.
