E8
Vacuum runs for only a very short time (1–2 minutes) on a full charge; E8 or low-battery icon flashes.
Battery Capacity Degradation
E9
Vacuum does not recognize that the dust bin is installed; E9 or the bin icon flashes, and the unit will not start.
Dust Bin Presence / Microswitch Fault
F1
The vacuum powers on, but suction is extremely weak; an F1 code or filter icon appears on the display.
Severely Clogged Filters / Restricted Airflow
F2
The vacuum pulses on and off rapidly; an F2 or blockage icon appears, and suction fluctuates.

F3
The LED display shows F3, and the vacuum will not start, often after long storage.
Battery Pack Deep Discharge Lockout
F4
The vacuum randomly shuts off when tilted or moved; an F4 tilt icon appears on the display.
Tilt / Orientation Sensor Fault
F5
The vacuum emits a burning smell, and F5 appears; the unit shuts down quickly.
Motor Overheat / Overcurrent Protection
Symptom
Battery indicator LEDs on the handle are inaccurate (e.g., show full, but the vacuum stops quickly).
Battery Level Calibration / Indicator Error
Symptom
Crevice tool or dusting brush does not fit securely onto the wand or handheld unit.
Accessory Fitment / Locking Tab Wear
Symptom
Dust escapes from joints or around the dust bin during use.
Dust Leakage / Seal Failure
Symptom

Symptom
LED lights on the floor nozzle do not turn on, but the brush roll still spins.
Nozzle LED Light Failure
Symptom
Mini motorized upholstery tool does not spin, while the main floor head works normally.
Accessory Motor Failure / Connection Issue
Symptom
On models with a trigger switch, the trigger feels loose or does not spring back properly.
Trigger Mechanism Wear / Spring Failure
