E0 error on induction cooktop accompanied by a beeping sound is a warning that the pot is not recognized or the pot base is not suitable (non-magnetic base, base diameter < 12cm,…). In fact, this is a safety feature, not necessarily a technical malfunction in most cases. The following article will analyze in detail 6 common causes leading to E0 error on induction cooktop, while also guiding how to quickly check and fix it.
E0 error on induction cooktops is often due to improper use by the user, but in some cases, it may also stem from internal technical faults. Below are the common causes and corresponding solutions.
| Cause | Probability | Solution |
| Pot not compatible with induction cooktop | 50% – 60% | Switch to a pot with a magnetic base and flat bottom |
| No pot on the cooktop / pot placed incorrectly | 15% – 20% | Place the pot in the cooking zone marked before turning on the cooktop |
| Warped pot bottom | 5% – 10% | Use a new pot with a flat, thick bottom and a diameter of 12 – 22cm |
| Pot diameter too small (< 12cm) | 5% – 10% | Use a pot with a diameter of 12 – 22cm as recommended by the manufacturer |
| Faulty pot detection sensor | < 5% | Contact a professional technician for assistance |
| Unstable voltage | < 5% | Weak, fluctuating power supply causing the cooktop not to operate continuously |
Pot not compatible with induction cooktop
Cause: users are reusing old pots from gas stoves or mistakenly buying aluminum, clay, or glass pots that do not support magnetic induction.
Solution: Replace with a pot that has a magnetic base (test with a magnet or check the label for identification), ensuring the base diameter is greater than 12cm, flat, and not warped.

Check the label on the bottom of the pot or use a magnet to see if the pot has a magnetic base
No pot on the cooktop / pot placed incorrectly
Cause: the user turns on the cooktop without placing a pot or is cooking and lifts the pot off the cooking zone for too long. When the cooktop is turned on without a container for food, if the power supply system transmits into the high-power circuit exceeding the threshold, the device may switch to report E2 error on induction cooktop to prevent localized overheating on the glass surface.
Solution: You just need to place the pot in the center of the cooking zone, the E0 error will automatically disappear and the cooktop will continue to heat. To ensure the device lasts longer, you should get into the habit of preparing the pot and food on the cooktop before turning it on.
Turning on the cooktop without placing a pot on the cooking zone will show E0 error, meaning ‘no pot’
Warped pot bottom
- Cause: When the pot bottom is uneven, it creates gaps between the pot and the cooktop glass. These gaps cause the magnetic field from the induction coil to be unstable, and the feedback signal to the control board is distorted.
- Solution: Check the flatness of the pot bottom by placing it on a flat surface. If you detect wobbling or significant unevenness, you need to replace it with pots that have 3 to 5 sturdy bottoms to maintain a completely flat contact surface, helping the cooktop operate smoothly and achieve the highest efficiency.
Fix E0 error on induction cooktop by using quality flat-bottom pots
Pot bottom diameter <12cm
- Cause: When the base area of the pot does not meet the minimum detection threshold (usually below 10 – 12cm), it will not be sufficient for the sensor to detect. The circuit board will immediately cut off the power and report an error to protect the heating system from energy loss.
- Solution: Check the size of the pot bottom, ensuring the diameter is between 12cm and 26cm for stable operation of the cooktop.
Choose a pot with a size suitable for the cooking zone size
Faulty pot detection sensor
This error often occurs when the cooktop is old, has moisture in the circuit, or insects invade causing short circuits in the internal components.
- Cause: lthis error often occurs when the cooktop is old, has moisture in the circuit, or insects invade causing short circuits in the internal components.
- Solution: Since this is a hardware error related to a complex circuit diagram, you should not attempt to disassemble or repair it at home to avoid causing fire or further damage. Please disconnect the power and immediately contact a professional technician or service center. Repair costs usually range from 200,000 to 500,000 VND (this price may vary depending on the type of cooktop (single/double) and replacement parts of each brand)

Unstable voltage
- Cause: When the power supply is too weak, it leads to continuous on-off fluctuations causing the induction cooktop to continuously report E0 error. Conversely, if the total power supply to the device suddenly spikes too high beyond the safety threshold (usually above 240V – 260V), the main circuit board will automatically cut off and activate the warning display E3 error on induction cooktop to prevent short circuit incidents.
- Solution: Use a voltage stabilizer or avoid plugging the cooktop into the same power source with large power-consuming devices.
