1, fault 3: the exhaust of Jiuyang electric pressure cooker is not good.

Cause of failure: the inlet and outlet of the pressure limiting valve are blocked, there is rust mud in the hammer of the pressure limiting valve, and the air hole is blocked.

Maintenance method: remove blockage, rust and pollutants, and add a small amount of cooking oil to make it rotate flexibly.

2. Fault 2: Air leakage of electric pressure cooker

Causes of failure: the valve seat of pressure limiting valve is loose, the seal and safety plug of safety valve are damaged, the compression spring of safety valve loses elasticity, there is a gap between valve needle and valve body, the safety plug is damaged, and the sealing ring of oil tank cover is invalid.

Maintenance method: Re-tighten the valve seat and disc; Replace the gaskets of pressure limiting valve, safety valve and safety plug; Replace the spring and adjust the gap. Replace the fusible sheet with a new fusible sheet; Replace the pot cover sealing ring.

3. Fault 1: Electric leakage of Jiuyang electric pressure cooker

Cause of failure: the insulation material of cable, socket or thermostat is damaged, which collides with the shell, the electrical components are damp, and the sealing insulation material of heating element of heating plate is aging.

Maintenance method: replace the insulation material, take out the shell metal for insulation treatment, and take off the bottom cover to dry. Take out the aging insulating material, seal it with silica gel, and use it after curing for 24 hours.

Mistake 4: The electric pressure cooker does not cook.

Cause of failure: there is a foreign body between the tank and the electric heating plate, the inner container of the tank is deformed, and there is a power supply voltage at the bottom of the tank. The inner container of the jar is inclined and hung on one side.

Maintenance method: remove foreign objects, find out the deformation, carefully knock the bottom of the tank with a wooden hammer for shaping, and make it closely contact with the electric heating plate after the tank rotates normally, and check whether the voltage is normal.

5. Fault 5: Failure of pressure maintaining function

Cause of failure: the power supply is disconnected or the connecting screw is loose; The timer is in the off position; The rectifier diode is burnt out; The contact piece of sensitive limit switch is deformed, loses elasticity and has poor contact.

Maintenance method: check the damaged or loose points and weld again; Adjust the timer knob to the required time scale; Replace the rectifier diode with the same specification; Correct with needle-nosed pliers. If not, replace the timer limit switch.

The above contents are about the fault causes and maintenance methods of Pentium electric pressure cooker.
