Hints and Tips
1. The induction hob cannot be turned on.
Make sure the induction hob is connected to the power supply and that it is switched on.
Check whether there is a power outage in your home or local area. If you’ve checked everything and the problem persists,
call a qualified technician.
2. The touch controls are unresponsive.
The controls are locked: Unlock the controls. See section using your induction cooktop for instructions.
3. The touch controls are difficult to operate.
There may be a slight film of water over the controls or you may be using the tip of your finger when touching the controls:
Make sure the touch control area is dry and use the ball of your finger when touching the controls.
6. The induction hob makes a low humming noise when used on a high heat setting.
This is caused by the technology of induction cooking: This is normal, the noise should quieten down or disappear
completely when you decrease the heat setting.
7. Fan noise coming from the induction hob.
A cooling fan built into your induction hob has come on to prevent the electronics from overheating. It may continue to run
even after you’ve turned the induction hob off: This is normal and needs no action. Do not switch the power to the
induction hob off at the wall while the fan is running.
8. Pans do not become hot and “ ” appears in the display.
The induction hob cannot detect the pan because it is not suitable for induction cooking. The induction hob cannot detect
the pan because it is too small for the cooking zone or not properly centred on it: Use cookware suitable for induction
cooking. See section “Choosing the Right Cookware”.
Centre the pan and make sure that its base matches the size of the cooking zone.
9. The induction hob or a cooking zone has turned itself off unexpectedly, a tone sounds and an error code is
displayed (typically alternating with one or two digits in the cooking timer display).
Technical fault: Please note down the error letters and numbers, switch the power to the induction hob off at the wall, and
contact a qualified technician.
4. The glass is being scratched.
Tough-edged cookware. Unsuitable, abrasive scourer or cleaning products being used: Use cookware with flat and
smooth bases. See “Choosing the Right Cookware” and “Care and Cleaning” for further advice.
5. Some pans make crackling or clicking noises.
This may be caused by the construction of your cookware (layers of different metals vibrating differently): This is normal,
the noise should quieten down or disappear completely.
Failure Display and Inspection
If an abnormality comes up, the induction hob will automatically enter the protective state and display
corresponding protective codes:
The above are the judgment and inspection of common failures.
Please do not disassemble the unit by yourself to avoid any danger or damage to the induction hob.

Possible causes
What to do
The appliance
does not work
Break in power supply
Please check the main power is normal; if the leakage protection switch is off; if there is a blown fuse,
replace it with a new one; if the main power is normal, check if the plug is connect with socket
appropriately; If the hob is wire connection type, disconnect the power, check if the wire is loose;
disconnect the power, check if main plug is off; Exclude above reasons, should be appliance fault, send
it to service center for repairing.
During heating,
the unit stop work.
Delay off timer activates.
No pan or pan unsuitable
Input power too low
Input power too high
Thermistor of coil short circuit.
Thermistor of coil open circuit.
Too high temperature
of IGBT thermistor.
Too high temperature
of coil thermistor.
IGBT thermistor short circuit
IGBT thermistor open circuit
Please check if set delay off function. If set delay off function, the unit will stop once delay off time out.
No pan, please put proper pan. PCB synchronization or drive circuit fault, please send the
appliance to service center for repairing.

Low voltage, voltage of the main power is less 180V. Please check if voltage of the main power is normal.
Once voltage of the main power returns normal, re-start the unit. Voltage of PCB fault, please send the
unit to service center for repairing.
High voltage, voltage of the main power exceeds 250V. Please check if voltage of the main power is
normal. Once voltage of the main power returns normal, re-start the unit. Voltage of PCB fault, please
send the unit to service center for repairing.
Sensor of coil thermistor connection error. Or detection part of PCB coil thermistor failure,
send to service center for reparing.
Too high temperature of IGBT thermistor, air outlet is blocked. Open air outlet, re-start the unit. If still
unsolved, it is possible that cooling fan connection error, cooling fan damaged, or drive circuit of fan
failure, send to service center for repairing. IGBT temperature sensor open circuit /short circuit.
Temperature detection part of PCB IGBT failure, send to service center for repairing.
Too high temperature on induction glass surface, please check if there is no water in pan. After
treatment, connect with power again. If still unsolved, it is possible that sensor of cooktop failure, send to
service center for repairing.
Senor of IGBT thermistor connection error. Or detection part of IGBT PCB sensor failure,
send to service center for repairing.
