Vacuum shows E16; unit powers off immediately when set to MAX or Turbo mode.

Safety first: Remove the battery before inspecting internal parts.

• Check for blockages: Ensure dustbin, cyclone, wand, and floor head are clear. Even partial blockages increase load in MAX mode.
• Clean filters: Dirty filters increase resistance and current draw. Clean or replace filters as needed.
• Battery health test: Fully charge the battery, then run the vacuum in low mode and time the runtime. If runtime is significantly below the specification, the battery is likely worn.
• Replace battery: Install a new genuine Battery Pack. Test MAX mode again.
• PCB issue: If a new battery and clear airflow still cause E16, the Main Control PCB may be misreading current and should be replaced by a technician.
