The reason why the rice cooker overflows when making porridge may be due to the following reasons:

1. The capacity of the rice cooker is not enough: If you put too much rice or water, causing the rice cooker to exceed the capacity limit, Then overflow is inevitable.

2. Failure to master the ratio of water to rice: Making porridge in a rice cooker requires a precise ratio of water to rice. If too much rice or too little water is added, the porridge will be too dense and cause overflow.

3. The water gauge is inaccurate: Some rice cookers are equipped with a water gauge, but it may not be very accurate, so you need to operate it multiple times to adjust the water to the correct level.

4. Poor installation: If the pot lid part is not installed correctly, or the steam escape channel is blocked, it may also cause the porridge to overflow.

Solution:

1. Cleaning work: First, clean up the overflowing porridge in time to avoid it remaining in the rice cooker and interfering with the next cooking.

2. Reduce the amount of porridge ingredients and increase the appropriate ratio of water to rice: You need to accurately understand the capacity of each rice cooker and add water and rice according to the ratio on the instruction manual.

3. Confirm the amount of water used: You need to confirm that the amount of water used is accurate. If necessary, you can use a standard measuring cup to confirm.

4. Check whether the pot lid is installed correctly: Before using the rice cooker, make sure the pot lid is installed correctly to prevent steam from escaping and causing the porridge to overflow.

In short, making porridge is a skill that requires mastering the method. It requires patience and multiple operations to accumulate skills, especially when you use a new rice cooker for the first time, or if the materials are different or the environment is different. When the temperature changes, you should use it carefully first and gradually master its operating tips to avoid problems.
