General Candy Induction Hob Troubleshooting

Some issues may not display a specific error code but still prevent your hob from functioning correctly.

After power is supplied, the LED display is not turned on:

• Causes:
  • No power connection or power switch is off.
  • Tripped circuit breaker or blown fuse.
  • Defective connections of the filter power board or the display board.
  • The filter power board is defective.
  • The display board is damaged.
• Solutions:
  • Check the power connection at the wall socket and ensure the hob’s isolator switch is on.
  • Check your household’s fuse box or consumer unit for a tripped breaker or blown fuse related to the hob circuit.
  • Turn off the power and check the wiring connections to both the filter power board and the display board (requires internal access and expertise).
  • If connections are secure, the filter power board or display board may be faulty and require professional replacement.

After power is supplied, some of the buttons don’t work, and the LED display works abnormally:

• Causes:

  • Moisture or debris on the control panel affecting specific buttons.
• Solutions:
  • Clean and dry the control panel thoroughly.
  • If cleaning doesn’t help, the display board is likely damaged and needs to be replaced by a qualified technician.

After power is supplied, the cooking mode symbol is turned on, but the hob doesn’t heat:

• Causes:
  • Incompatible cookware is being used (induction hobs require magnetic pots and pans).
  • The pot diameter is too small for the selected heating zone.
  • Defective cooling fan motor or overheating causing a safety shutdown (similar to E2).
  • The power board responsible for generating the induction field is damaged.
  • The hob is too hot from previous use or poor ventilation.
  • The pot detection circuit is faulty.
• Solutions:
  • Ensure you are using suitable, magnetic cookware of an appropriate size for the heating zone. You can test if a pan is compatible by seeing if a magnet sticks to the base.
  • Allow the hob to cool down if it has been in heavy use.
  • Check and replace the cooling fan motor if it is not functioning.
  • Verify proper ventilation around the hob.
  • If incompatible cookware is ruled out and cooling/ventilation is adequate, the power board or pot detection circuit may be damaged and require professional replacement.

The cooking is abruptly halted, and one of the heating zones displays “u”:

• Meaning: The hob has detected an issue with the pan on that zone.
• Causes:
  • The material of the pot is not suitable for induction (not magnetic).
  • The pot diameter is too small for the heating zone.
  • The pot was removed from the heating zone.
  • Too high a temperature on the cooking hob (overheating).
  • Faulty pot detection circuit.
• Solutions:
  • Use the proper magnetic cookware of an appropriate size. Refer to your hob’s instruction manual for recommended cookware.
  • Ensure the pot is correctly centered on the heating zone.
  • Allow the hob to cool down if it has been in prolonged use. Check ventilation.
  • If using correct cookware and the issue persists, the pot detection circuit or the power board may be damaged and require professional service.

CANDY INDUCTION HOB DEMO MODE

Some Candy induction hobs have a “Demo Mode” which is used for display purposes in stores. In this mode, the hob appears to function normally, but the heating elements do not generate heat. If your hob seems to be on but won’t heat despite using correct cookware, check if it’s in demo mode.

How to place the Candy induction hob into DEMO mode:

• This process can vary by model, but commonly involves pressing and holding a combination of keys. A frequent method is to touch the Timer – and Timer + buttons simultaneously for several seconds while the hob is in standby mode. The display might show “dE” or similar to indicate demo mode.

How to deactivate DEMO mode:

• Again, this can vary, but often involves repeating the activation step. Touch the Timer – and Timer + buttons simultaneously for several seconds while the hob is in standby mode.
• Look for a change in the display, such as “dE” disappearing or the indicators returning to their normal standby state (e.g., showing “0”).

If these steps don’t work, consult your specific hob’s user manual for the correct procedure to enter and exit demo mode.

When to Call a Professional

While some issues can be resolved with simple checks and cleaning, many error codes and persistent problems with induction hobs indicate internal electronic or component failures.

You should contact a qualified appliance technician if:

• The error code or issue persists after trying the suggested solutions.
• The troubleshooting steps require opening the hob’s casing to access internal components.
• You suspect a problem with the electrical supply or internal wiring.
• You are uncomfortable or unsure about performing any of the troubleshooting steps.

Attempting repairs without the necessary knowledge and tools can be dangerous and may cause further damage to the appliance. Always prioritize your safety.
