Possible Causes

Overcurrent on motor circuit, Shorted wiring in floor head, Faulty sensor feedback to control board, Internal short on control PCB

How to Fix / Troubleshooting

Safety first: Remove the battery immediately if you suspect an electrical short. Do not continue to operate the unit.

  • Isolate floor head: Remove the floor nozzle and test the vacuum with only the handheld unit. If it runs normally, the fault is likely in the nozzle.
  • Inspect for damage: Check the nozzle and wand for crushed or pinched areas that could hide damaged wiring.
  • Smell for burning: A burnt smell indicates internal electrical damage; do not continue using the vacuum.
  • Reset: Remove the battery for 5–10 minutes, then reinstall and test. If beeping and shutdown persist, internal electronics are likely damaged.

Audible alarms for internal errors generally require professional diagnosis and replacement of the affected component (nozzle wiring, harness, or control board).
