What should you do if the machine is too full of oil?

Turning the machine off to prevent overflow is the most appropriate action when the oil level is too high. This step is critical for safety and equipment integrity. If the oil is left to overflow, it can create a hazardous situation, potentially leading to burns, slips, or fires, as well as damaging the cooking equipment.

By switching off the machine, you can avoid the risks associated with overflow and ensure that no further cooking or heating occurs, which would exacerbate the problem. Once the machine is off, additional steps can be taken to address the excessive oil, such as allowing it to cool down or safely disposing of excess oil as needed.

Using the oil immediately by starting cooking may not adequately address the overflow and could lead to dangerous situations. Meanwhile, flushing the oil out into a container should only be done after considering proper procedures for handling and disposing of cooking oil, and it assumes that the machine is safe to operate in such a way, which is not the case when it's too full.
