Battered food should not be put into the basket directly. The batter will wrap around the basket coils and get stuck. Lower the basket into the oil first. Wearing gloves when placing battered food directly in oil.
Never mix different oils together as each type of oil has a different frying temperature, which can cause the oils to emulsify and boil over during cooking.
a) The fryer was filled beyond the maximum level (either with oil or with food in the frying basket). Check the oil level. The bowl is marked with a minimum and a maximum level. b) Wet food has been dropped into the oil. Dry the food completely or remove any loose ice from frozen foods before frying.
There are usually two markers in the tank: minimum and maximum. See the instructions for use. In any case, do not exceed the maximum level, and do not add less oil than the minimum level indicated.
