E01
Cordless vacuum will not power on when main switch is set to ON and battery is installed
Main Power Supply / Control Electronics Fault
E02
Cordless vacuum powers on briefly, then shuts down with E02 on the display.
Overcurrent / Motor Overload Protection
E03
Vacuum stops during use and displays E03; it will restart after a cool-down period.
Motor Overtemperature Protection
E04
Cordless vacuum will not start and shows E04 immediately when powered on
Battery Pack Communication / Identification Error
E05
Vacuum stops and displays E05 when used with a connected cordless tool via Bluetooth or remote
Tool Start / Bluetooth Communication Fault
E06
Vacuum display shows E06, and suction is very weak or absent.
Airflow / Suction Sensor Fault
E07
Vacuum attempts to start, motor jerks or hums, then E07 appears and it shuts down
Motor Start / Rotor Position Detection Fault
E08
Vacuum stops with E08 after a short run time; the battery still shows charge on its LEDs.
Undervoltage / Battery Protection Triggered Under Load
E09
Vacuum display shows E09 and the unit will not run when connected to a charger or power adapter (if the model supports hybrid operation).
Charging / External Power Input Fault
E10
Vacuum shows E10 and runs only at a single speed or not at all when the speed is adjusted.
Speed Control / Potentiometer Fault
E11
Vacuum displays E11 and shuts down when the filter cleaning function is activated (if equipped).
Automatic Filter Cleaning Mechanism Fault
E12
Vacuum shows E12 and will not start when the dust container is removed or not seated correctly.
Container Presence / Safety Interlock Fault
E13
Vacuum displays E13 and motor speed surges up and down without user input.
Motor Speed Feedback / Tachometer Fault
E14
Vacuum shows E14 and emits a burning smell or visible sparks from the motor area before shutting down.
Motor Short Circuit / Insulation Failure
E15
Vacuum displays E15 and none of the buttons or controls respond.
User Interface / Keypad Communication Fault
E16
Vacuum shows E16 and the Bluetooth indicator flashes abnormally; the remote cannot connect.
Bluetooth Module Hardware Fault
E17
Vacuum displays E17 and shuts down when fine dust extraction is used continuously.
Fine Dust Filter Differential Pressure Fault
E18
Vacuum displays E18 and will not operate when used in auto-start mode with a paired tool.
Auto-Start Logic / Trigger Detection Fault
Symptom
Bluetooth remote or tool module does not start the vacuum, but the vacuum runs in manual mode.
Bluetooth Control Path Failure
Symptom
Buttons on the control panel do not respond or require very hard pressing.
Keypad / Button Failure
Symptom
Cordless vacuum will not turn on at all; no lights or response when the battery is installed.
Complete Power Loss
Symptom
Dust or debris leaks from around the container or hose connection during use.
Air Leakage / Poor Sealing
Symptom
Fine dust escapes from the exhaust air; the air seems dusty despite the filter being installed.
Filter Bypass / HEPA Filter Failure
Symptom
Main power switch feels loose, sticks, or does not stay in position.
Mechanical Switch Wear / Failure
Symptom
Suction is weak even though the motor sounds normal.
Reduced Airflow / Suction Loss
Symptom
The vacuum body becomes unusually hot to the touch during normal use.
Overheating Due to Restricted Cooling
Symptom
The vacuum cannot stand or roll properly; the chassis feels unstable or tips easily.
Chassis / Wheel Damage
Symptom
The vacuum does not hold the hose securely; the hose frequently falls out during use.
Hose Connection / Locking Fault
Symptom
The vacuum does not start when the container is very full; it starts again after emptying.
Overfill Protection / Airflow Restriction
Symptom
The vacuum emits a strong burning or electrical smell during use but continues to run.
Early-Stage Motor or Electronics Overheating
Symptom
The vacuum produces a rattling noise from inside the container during use.
Loose Internal Components or Debris
Symptom
The vacuum runs but the attached power tool or accessory is not being adequately cleaned (poor extraction at the tool).
Tool-End Extraction Inefficiency
Symptom
The vacuum starts but immediately shuts off when the hose is blocked by hand, with no error code.
Overcurrent / Overload Protection Without Display Code
Symptom
Vacuum emits unusual clicking or chirping sounds from the electronics area when starting or stopping.
Relay or Electronic Switching Noise
Symptom
Vacuum makes a loud, high-pitched whine or grinding noise during operation.
Motor Bearing or Fan Impeller Damage
Symptom
Vacuum operates for only a few minutes on a full charge before shutting off; no error code is displayed.
Reduced Runtime / Battery Capacity Loss
Symptom
Vacuum shuts off intermittently when moved or bumped, then restarts when tapped or when the battery is reseated.
Intermittent Power Connection
Symptom
Vacuum vibrates excessively while operating, even on a flat surface.
Mechanical Imbalance / Loose Components
