The multicooker (of which Cookeo is the most common model) is a very practical kitchen appliance that can have multiple cooking programs: steam cooker, cooker, rice cooker, slow cooker or fryer.
It happens that the multicooker gets stuck in preheating mode. In this case, it will be necessary to check:
- water in the tank
- the clamping screw
- the temperature probe
- the lower probe
- resistance
- the marble
A multicooker is an incredibly versatile kitchen tool that simplifies meal preparation. However, like any appliance, it can occasionally run into problems. One issue that users might encounter is the multicooker getting stuck or locked in preheating mode. In this article, we will explore some reasons why this might happen and suggest potential solutions.
Reason 1: Sensor Malfunction
Multicookers typically use temperature sensors to switch from preheating to cooking mode once the desired temperature is reached. If the sensor malfunctions or fails, the multicooker might remain in preheating mode.
Solution: A malfunctioning sensor generally needs to be replaced. This should be done by a professional technician to ensure the new sensor is installed correctly and to prevent any potential damage to the appliance.
Reason 2: Software Glitch
Sometimes, the issue might be due to a software glitch. This can cause the multicooker’s controls to lock in preheating mode, even though the appliance has reached the correct temperature.
Solution: Try unplugging the multicooker, waiting for a few minutes, and then plugging it back in. This “hard reset” can often clear minor software glitches. If this doesn’t resolve the issue, consult the manufacturer or a professional technician.
Reason 3: Insufficient Heat
If the multicooker isn’t able to generate enough heat during preheating, it might remain in this mode. This could be due to issues with the heating element or other internal components.
Solution: If you suspect a problem with the heating element or other internal components, contact a professional repair service. These parts are difficult to replace without the right expertise and tools, and improper handling can be dangerous.
Reason 4: Lid or Seal Issue
Some multicookers won’t move out of preheating mode until the lid is securely fastened. If the lid isn’t properly sealed, the cooker might remain in preheating mode.
Solution: Check the lid and the sealing ring for any damage. Make sure the lid is correctly aligned and properly fastened. If the sealing ring is damaged, replace it according to the manufacturer’s instructions.
CHECK CLAMP SCREW
Your multicooker may be stuck in preheat mode because the screw under the lid is too tight.
Check if the screw is damaged, not too tight or dirty. If it is in poor condition, replace it.
INSPECT LOWER PROBE
The lower probe or bowl sensor is an element of the multicooker that will detect the presence of a bowl. To access the bottom probe, you will need to remove the basket and the multicooker bowl.
- Close and flip the multicooker to access the screw bottom.
- Then unscrew the fixing screws of the sensor and remove the sensor from its place.
- Check for cut, twisted, or burnt sensor connection wires. If the probe is in poor condition, replace it.
TEST RESISTANCE
You will need to test the resistor with a multimeter to make sure it works. It has the shape of a metal disk and is located in the middle, under the multicooker.
- Disassemble the multicooker from below to gain access to the heating element.
- Calibrate the multimeter to the lower of the ohmic values, 600 or 200 depending on your multimeter.
- Place two multimeter probes on the two lugs of the resistor. To access it, remove the screws.
- If the value is OL, 1 or less than 20 ohms, your resistor is bad.
Conclusion
A multicooker that remains locked in preheating mode can be frustrating and can disrupt your meal preparation. By understanding the potential causes, you can try basic troubleshooting or know when it’s time to call in a professional. Regular maintenance and care can also prevent many common multicooker problems, helping to keep your appliance in optimal working condition.
