Vacuum shows 'F3'; runs erratically with speed surging up and down.
Motor Speed Feedback / Hall Sensor Fault
F4
Vacuum shows 'F4'; shuts down immediately when the trigger is pulled, even with a full battery.
Short Circuit Detected
F5
Vacuum shows 'F5'; battery indicator behaves erratically (jumping from full to empty).
Battery Fuel Gauge / Sensing Fault
FLT
The display shows 'FLT' or a filter icon, suction drops, and the vacuum cycles on/off.
Filter Clogged / Restricted Airflow
H2O
The display shows 'H2O' or a water droplet icon, and the vacuum stops after picking up liquid.
Moisture Detected in Air Path
LO
The display or LED shows 'LO' or continuous slow red flashing, and the vacuum runs only briefly or not at all.
Low Battery Charge
Symptom
Battery will not latch securely into the vacuum, causing intermittent power loss.
Battery Latch / Housing Wear
Symptom

Mini Motorized Tool Motor / Gear Failure
Symptom
Vacuum body becomes unusually hot to the touch during normal use.
Chronic Overheating
Symptom
Vacuum emits a burning smell during operation.
Motor Overheating / Electrical Insulation Breakdown
Symptom

Symptom
Vacuum leaves lines of debris behind and does not pick up well from carpets.
Worn or Jammed Brush Roll
Symptom
Vacuum loses suction only when using certain attachments.
Attachment Air Leak / Local Blockage
Symptom
Vacuum makes a grinding or rattling noise from the floor head.
Brush Roll Bearing Wear / Foreign Object in Floor Head
Symptom

Air Leak / Partial Blockage
Symptom
Vacuum runs but produces no suction at the floor head, while suction at the handheld inlet is normal.
Wand or Floor Nozzle Blockage / Air Leak
Symptom
Vacuum runs only for a few seconds then shuts off, but no error code is displayed.
Thermal or Overcurrent Cut-Out Without Display Indication
Symptom
Vacuum runs only on high power and will not switch to eco/low mode.
Mode Control Stuck / Low-Speed Circuit Fault
Symptom
Vacuum shuts off when tilted to certain angles or when lifted.
Tilt/Safety Sensor Over-Sensitivity or Loose Connection
Symptom
Vacuum smells musty or produces an unpleasant odor during use.
Contaminated Filters / Dust Bin
Symptom
Vacuum spits debris back out of the nozzle while in use.
Airflow Reversal / Nozzle Blockage
Symptom
Vacuum vibrates excessively, especially when using the motorized floor head.
