How to Fix E1 Error in an Induction Cooker: A Step-by-Step Guide
This guide provides a complete step-by-step solution on how to fix the E1 error in an induction cooker, including tips on checking input AC voltage, filter capacitor, and transistors.
An induction cooker is one of the most useful home appliances, but sometimes it can show errors such as E1 error. This error can be due to various reasons, including low input AC voltage, damage to the filter capacitor, or issues with the driver section. Here is a complete guide on how to fix the E1 error in an induction cooker.
- Check for No Pot on the Induction Cooker: The E1 error can sometimes appear even if there is no pot on the induction cooker. Ensure that there is a pot or pan placed on the cooktop before trying to cook.
- Check Input AC Voltage: One of the main reasons for the E1 error is low input AC voltage. Ensure that the voltage is within the normal range.
- Check Filter Capacitor: The E1 error can also occur due to damage to the 5mfd/400volt filter capacitor or 0.3 mfd/1200volt capacitor. Check these capacitors for any damage and replace them if necessary.
- Check IGBT Short: The E1 error can also occur due to a short between the Gate and Source in the IGBT. This can be fixed by replacing the IGBT.
- Check Transistors 8050 and 8550: The transistors 8050 and 8550 of the driver section can also cause the E1 error if they are shorted or open. Check and replace these transistors if necessary.
- Check for DC 18Volt: The driver section requires DC 18Volt to work properly. If there is no 18Volt in the driver section, the E1 error can appear. Ensure that the DC 18Volt is present in the driver section.
- Check Voltage Divider Resistors: From the rectifier section to the microcontroller input AC voltage sensing in the SMPS section, a 1-watt voltage divider resistor is connected to the output of 4007 diodes. If any of these voltage divider resistors are open, the induction cooktop will show the E1 error. Check and replace these resistors if necessary.
- Check IN4007 Diode: The IN4007 diode of the SMPS section can also cause the E1 error if it is shorted or open. Check and replace the diode if necessary.

frequently asked questions about induction cookers:
- What is an induction cooker? Answer: An induction cooker is a type of stove that uses electromagnetic energy to heat pots and pans. It is considered more efficient and safer compared to traditional gas or electric stoves.
- How does an induction cooker work? Answer: An induction cooker uses magnetic fields to generate heat directly in the pot or pan, rather than heating up the stove surface. This heat is generated when the magnetic field induces an electric current in the metal of the cookware, which in turn generates heat.
- What types of cookware can be used on an induction cooker? Answer: To use an induction cooker, the cookware must be magnetic. This means that it should be made of cast iron or stainless steel. Some aluminum and copper cookware may also work if they have a magnetic layer on the bottom.
- Is induction cooking faster than traditional cooking methods? Answer: Yes, induction cooking is generally faster compared to traditional cooking methods. This is because the heat is generated directly in the cookware, which means that the cooking time is shorter.
- Is induction cooking safe? Answer: Yes, induction cooking is considered to be safer compared to traditional gas or electric stovetops. The surface of the stove remains cool to the touch, which means that there is a reduced risk of accidental burns.
- How do I clean my induction cooker? Answer: Cleaning an induction cooker is very simple. Simply wipe down the surface with a damp cloth, and if there are any stubborn stains, you can use a stovetop cleaner specifically designed for induction cookers.
- How do I troubleshoot my induction cooker if it’s not working? Answer: If your induction cooker is not working, the first step is to check if it’s properly connected to a power source. If it is, then check if the cookware is compatible with the cooker. If the cooker still isn’t working, consult the manufacturer’s manual or contact customer service for further assistance.
- What is the warranty on an induction cooker? Answer: The warranty on an induction cooker varies depending on the manufacturer. Some induction cookers come with a one-year warranty, while others have a warranty of two or more years.
- Can an induction cooker be used outdoors? Answer: No, an induction cooker should not be used outdoors. It is designed for indoor use only.
- How energy efficient is an induction cooker compared to other cooking methods? Answer: Induction cooking is considered to be more energy efficient compared to traditional gas or electric stovetops. This is because the heat is generated directly in the cookware, which means that less energy is wasted compared to traditional stovetops where the heat is generated on the stove surface.
