If your induction cooktop powers on but will not heat, beeps and shuts off, or shows an error code, the cause is usually simple and fixable. Most problems come down to incompatible cookware, power supply, overheating or a blocked fan. This guide walks you through the common causes and step-by-step fixes before you consider repair or replacement.
Quick Safety First
Switch off and unplug the cooktop before inspecting it. Never open the casing or touch internal electronics. If the fault is internal and not covered below, contact the service centre rather than attempting a repair yourself.
Common Causes and Fixes
| Symptom | Likely Cause | Fix |
|---|---|---|
| Beeps, no heat | Incompatible cookware | Use a magnetic-base pan |
| Dead, no display | Power supply fault | Try another socket; check cord |
| Error code shown | Various (see manual) | Match code to manual; reset |
| Heats then stops | Overheating / blocked fan | Cool down; clear vents |
| Pan not detected | Pan too small or off-centre | Centre a larger compatible pan |
Step 1: Check Your Cookware
This is the most common cause. Induction only heats magnetic cookware. Hold a fridge magnet to the base of your pan — if it sticks firmly, the pan will work. Aluminium, copper, glass and ceramic pans will not heat. Also make sure the pan base is flat and at least the minimum diameter (usually 12 cm) so the cooktop detects it.
Step 2: Check the Power Supply
Plug into a different, properly rated socket — induction draws high current, so a weak socket or extension cord can cause faults. Inspect the cord for damage and confirm your mains voltage is stable. Low voltage can stop the cooktop heating.
Step 3: Read the Error Code
Most cooktops show a code like E0, E1 or E6 when something is wrong. E0 usually means no pan or incompatible cookware; other codes can indicate voltage issues or overheating. Check the user manual for your model’s code list, then act on the specific cause. Switching off for a minute often resets a temporary error.
Step 4: Let It Cool and Clear the Fan
If the cooktop heats then shuts off, it may be overheating. Make sure the air vents and cooling fan at the back or bottom are not blocked by walls, cloth or dust. Give it 15 to 20 minutes to cool, clear the vents, and try again on a cooler surface with space around it.

When to Repair or Replace
If the cooktop is dead after checking power, shows a persistent internal error, or trips your circuit repeatedly, the electronics or coil may have failed. Contact the brand service centre while under warranty; for older budget units, replacement is often more economical.

Frequently Asked Questions
Why does my induction cooktop beep and not heat?
Almost always because the pan is not induction-compatible. Use a magnetic-base pan; a fridge magnet that sticks to the base confirms it will work.
What does the E0 error mean?
On most induction cooktops, E0 means no pan is detected or the cookware is incompatible. Place a suitable magnetic pan centred on the cooktop.
Why does my cooktop heat then switch off?
Usually overheating from a blocked fan or vents. Let it cool, clear the air vents and use it on an open surface with room to breathe.
Can low voltage stop induction from heating?
Yes. Induction needs adequate, stable voltage and current. A weak socket, thin extension cord or low mains voltage can prevent heating.
Is it worth repairing an induction cooktop?
Under warranty, yes — use the service centre. For older budget cooktops with internal faults, replacement is usually more cost-effective.
