⚠️ Induction Cooktop Not Working? Troubleshooting & Error Codes
Before booking a service call, it's worth running through these common induction cooktop issues — most have a simple, safe fix you can check yourself.
"No pan detected" or the zone won't heat
By far the most common issue. Check that your cookware is actually induction-compatible (see our cookware guide for the magnet test) and that the pan base covers enough of the zone — small, off-centre, or warped pans can fail to register even if the material itself is magnetic.
Cooktop won't turn on at all
- Confirm the child lock isn't engaged — usually indicated by a lock icon, cleared with a press-and-hold combination specific to your model
- Check the circuit breaker or power point hasn't tripped, particularly after a storm or power fluctuation
- Make sure the surface is completely dry — some models won't respond to touch controls if water has pooled near the sensor area
Zone cuts out mid-cook
Most induction cooktops have built-in overheat protection that pauses a zone if the cookware or cooktop surface gets too hot, and a maximum continuous-use timer per zone (often one to three hours) as a safety default. This isn't a fault — it's designed, intentional behaviour to prevent unattended overheating.
Error codes (E1, E2, F codes, and similar)
Exact codes vary by brand and model, but common categories are: a power supply or voltage fault, an overheating sensor trip, a pan-detection fault, or a control board communication error. Check your specific model's manual — searchable by brand plus "induction cooktop manual" — for the exact meaning of a given code, and don't attempt to diagnose internal electronics yourself unless you're a licensed electrician.
Buzzing or clicking noise
A faint hum or click during normal operation is expected — it's the induction coil's driving electronics at work. Loud buzzing that changes noticeably with pan position usually means the cookware base isn't fully flat, or isn't sufficiently induction-grade, rather than a fault with the cooktop itself.
When to call a technician
If the cooktop repeatedly trips your circuit breaker, shows a persistent error code after a full power cycle, or has a cracked or visibly damaged glass surface, stop using it immediately and contact a licensed technician or the manufacturer's service line — these are genuine safety issues, not DIY fixes, and continuing to use a damaged cooktop carries real risk.
Frequently asked questions
Is it safe to keep using an induction cooktop that shows an intermittent error?
Not recommended — an intermittent fault can indicate a developing electrical issue. Get it checked by a licensed technician rather than continuing to use it and hoping it resolves itself.
Why does my cooktop only work with some of my pans?
This is almost always a cookware compatibility issue, not a cooktop fault — see the magnet test in our cookware guide to confirm which of your pans are actually induction-rated.
Can a power surge damage an induction cooktop?
Yes, significant voltage spikes can potentially damage the internal inverter electronics — a surge-protected circuit or whole-home surge protection is a reasonable precaution, particularly in areas prone to grid fluctuations.
