1, insufficient power: the power of the electric stew pot is low or because of the use of a longer period of time leading to a decline in heating efficiency, not enough to let the pot ingredients quickly warm up to the boiling point.

2, too much or too little water: adding too much water may extend the boiling time, while adding too little water may lead to the heat source can not be effectively transmitted to the ingredients.

3, the amount or type of ingredients: if the pot into a large number of ingredients or all the ingredients are not easy to cook (such as beans, meat, etc.), they will absorb a lot of heat, so that the temperature of the water to rise slower.

4, pot problems: the electric stew pot itself may be faulty, such as heating element damage or poor contact, can not be normal heat.

5, poor sealing: if the lid is not sealed tightly, the heat is easy to dissipate, which may also lead to a longer period of time can not boil.
