Complete list of fault codes and troubleshooting guides. Use the search below to find your specific error.
Advertisements
B1
The battery indicator shows one flashing LED, and the vacuum stops after a few seconds, even after a long charge.
Battery Capacity Degradation
B2
All battery LEDs flash together, and the vacuum will not start, often after storage.
Battery Pack Lockout / Deep Discharge Protection
E1
Cordless vacuum will not power on, battery LEDs flash once then go dark
Battery Pack Protection Trip / Undervoltage Lockout
E2
Vacuum cuts out within a few seconds of starting, E2 displayed on handle or battery LED flashes red twice repeatedly
Overcurrent / Motor Overload Protection
E3
Brush bar will not rotate, E3 shown on display or brush LED flashes red, suction still works
Motorised Floorhead Brush Jam / Overload
E4
Vacuum stops and displays E4 or flashes four red LEDs when used on high power for a short time
Overtemperature Shutdown (Motor or Battery Overheat)
E5
Vacuum will not charge; the charger LED flashes or E5 appears on the display when the battery is docked.
Battery Charging Fault / Charger-Battery Communication Error
E6
The vacuum powers on but immediately shuts off with E6 or six red flashes, even with an empty bin and clean filters.
Main Control PCB Fault / Internal Electronics Error
E7
The LED indicator shows E7 or seven red flashes when trying to start; the motor does not spin.
Motor Tachometer / Speed Feedback Error
E8
The display shows E8 or battery LEDs flash in a pattern when filters are missing or incorrectly fitted.
Filter Detection / Airflow Sensor Fault
E9
The vacuum runs only on low power, cannot switch to turbo, or displays E9 or nine red flashes when pressing the power mode button.
High-Power Mode Inhibited / Battery Current Limit
F1
The charger LED flashes rapidly, and the vacuum battery does not accept a charge; F1 is shown on some docking stations.
Battery Overvoltage / Incompatible Battery Detected
F2
The charger LED stays off when plugged in; an F2 error appears on some smart bases, and the vacuum battery appears dead.
Charger Power Supply Failure
Symptom
Attachments (crevice tool, upholstery tool) fall off easily during use.
Accessory Retention / Nozzle Clip Wear
Symptom
Battery gets excessively hot to touch during use or charging.
Battery Overheating
Symptom
Dust or fine powder blowing out of the exhaust vent during use.
Filter Bypass / Damaged HEPA Filter
Symptom
Excessive vibration is felt in hand during use.
Rotating Assembly Imbalance
Symptom
Floorhead lights up, but the brush bar does not spin; suction is normal.
Brush Motor / Drive Failure
Symptom
Static shocks are felt when touching metal parts of the vacuum during use.
Static Electricity Buildup
Symptom
The LED headlight on the floorhead does not work, but the brush spins normally.
Floorhead LED Circuit Failure
Symptom
The charger or docking station makes a buzzing or humming noise.
Charger Transformer / Electronic Noise
Symptom
The dust bin is difficult to remove or reattach to the main body.
Dust Bin Alignment / Mount Wear
Symptom
The dust bin will not latch closed or pops open during use.
Dust Bin Latch / Hinge Failure
Symptom
The extension wand or tube collapses or separates during use.
Wand Lock / Telescopic Mechanism Failure
Symptom
The vacuum body becomes uncomfortably hot to hold near the motor area.
Motor Overheating / Restricted Cooling Path
Symptom
The vacuum cannot be wall-mounted securely; the dock feels loose or unstable.
Wall Dock Mounting / Bracket Failure
Symptom
The vacuum has very weak suction, even with a fully charged battery.
Airflow Restriction / Cyclone Blockage
Symptom
Unpleasant musty or burning smell from the vacuum exhaust.
Contaminated Filters / Overheated Dust
Symptom
Vacuum leaves lines of debris on carpet and does not pick up well from the floor.
Brush Bar Performance Degradation
Symptom
Vacuum makes a rattling or clunking noise from the floorhead while in use.
Brush Bar / Floorhead Mechanical Wear
Symptom
Vacuum runs but makes a loud, high-pitched whine or screeching noise.
Motor Bearing Wear / Fan Damage
Symptom
Vacuum runs only when the trigger is held but does not latch in continuous mode (if the model has a latch).
Continuous Run Latch / Mode Switch Fault
Symptom
Vacuum runtime is much shorter than specified, but the battery indicator still shows charge remaining.
Battery Calibration / Capacity Loss
Symptom
Vacuum shuts off intermittently during use without any error code, then restarts after a short wait.
Thermal Cut-Out Activation
Symptom
Vacuum will not start at all, no lights, but the battery charges normally on the charger.
Power Path / Trigger Switch Failure
Symptom
Visible sparks or a strong burning smell from the motor area.
Motor Electrical Failure
