None Induction Hob: not functioning
What is this symptom?
Is your induction hob not powering on or heating? This issue can stem from several causes, such as power supply problems, child lock activation, or incompatible cookware. Whether it’s a minor reset or a more complex repair, understanding the symptoms can help you troubleshoot effectively.
Possible Causes
Power not reaching unit (breaker or connection)
How to Identify: No lights, no response when pressing power; other appliances on same circuit also off.
Part: Electrical supply / breaker
Child lock or all‑lock safety feature engaged
How to Identify: Control panel lights show lock icon or no controls respond until lock is released; procedure varies by manufacturer.
Part: Control panel safety lock
Incompatible or improperly placed cookware (for hobs with induction detection)
How to Identify: Power seems on but no heating until magnetic, flat‑bottomed cookware is centered correctly; error or blink codes may show.
Part: Induction sensor/cookware interface
Internal sensor or control board failure
How to Identify: Unit will not respond after power and lock checks; error codes may persist; resets don’t help.
Part: Internal sensor or control electronics
Top plate damage or water ingress
How to Identify: Visible cracks or recent spills; intermittent or no power activate; error codes may occur.
Part: Glass‑ceramic top / internal circuitry

Next step
Choose the next step for not functioning
Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Browse by model — no specific failed part is claimed
Model-compatible Induction Hob parts
Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Search results are not a diagnosis. Verify both the complete appliance model and the retailer's fit information before ordering.

User Suggested Solutions
-
Check the power supply: Ensure the induction hob is plugged in, check the circuit breaker and reset if necessary. If the hob is hardwired, inspect the fuse box for blown fuses.
-
Reset the induction hob: Turn off the cooktop, unplug it for a minute, then plug it back in and turn it on.
-
Inspect and replace the control board or touch panel: If the buttons are unresponsive and the power supply is fine, the control board may need replacement.
-
Check for overheating: Allow the hob to cool down if it has shut off due to overheating. Ensure proper ventilation and check for any obstructions.
-
Test cookware compatibility: Ensure that the cookware used is induction-compatible. Use a magnet to check if it adheres to the base of the cookware.
