Maintenance method:

1. Turn the pan upside down, remove the small screws with a screwdriver and open the bottom cover.

2. After opening the bottom cover, you can see the internal structure and find the pressure switch.

3. Pressure switches are installed on the side. After finding the pressure switch, dial it up from the bottom by hand until it clicks. Just dial it a few times and then plug it in.

4. Check whether the plug is plugged in. If the plug is plugged in, it may be that the wires inside are not completely plugged in. You can find a sharp tool to plug the wire of the pressure switch from the hole above and let it plug in completely.

5. If you can't turn the pressure switch by hand in the second step, it may be that the pressure switch is dead. You can use a screwdriver to extend from the side of the pressure switch, tilt the pressure switch to make it return to normal, and then turn the pressure switch by hand until it clicks.

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 during use and burn people.

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 be completely coincident with the handle of the pot, so as to put the stove in order to cook food, otherwise it will cause the accident of the pot flying cover.
