How to Fix / Troubleshooting

Safety: Remove the battery immediately. Do not attempt to power the unit again until inspected.

Disconnect accessories: Remove all attachments and the wand. Try powering the main unit alone (with battery reinstalled). If E8 disappears, the short is likely in an accessory or wand.
Inspect wiring: Look for visible damage to the wand, floor head, and handle—cracks, crushed areas, or exposed wires.
Smell test: If you detect a strong burnt smell from the motor housing, the motor windings may be shorted.
Do not bypass protection: Never attempt to bridge fuses or modify wiring to "force" the vacuum to run; this is a fire and shock hazard.
Service: Replace the shorted component (often the main motor assembly, wand harness, or powered head) through an authorized repair center.

Cordless vacuum shows E8 and shuts down immediately when the trigger is pulled.
