Due to short circuit fault and other reasons, the line voltage will be greatly reduced or even disappeared in a short time. It will cause damage to lines and electrical equipment. For example, the motor is exhausted and blocked, resulting in overcurrent several times the rated current and burning out the motor.

After the voltage is restored, a large number of motors will start themselves, which will greatly reduce the motor voltage and cause harm. It is necessary to contact after-sales maintenance to help solve it. If you don't have professional knowledge in this field, avoid dismantling and repairing without permission.

Precautions:

1. Inspection before use: When using the electric pressure cooker, carefully check whether the exhaust hole is clear and whether the hole under the valve seat of the safety valve is blocked by residual rice grains or other food residues. If it is blocked by food during use, the pot should be removed from the fire source, and the air holes should be cleaned after forced cooling, otherwise the food will be sprayed out and burn people during use.

2. Check whether the rubber gasket is aging. The rubber sealing ring will age after being used for a period of time. Aging aprons are easy to make the pressure cooker leak and need to be updated in time.

3. The handle of the pot cover must completely coincide with the handle of the pot before it can be placed on the stove to cook food, otherwise it will cause the accident of the pot cover popping up.

4. When in use, in order to increase the pressure in the pot, someone forcibly increases the weight on the pressure valve and forcibly shortens the production time. I don't know that the pressure in the pot has strict technical parameters.
