Electric pressure cooker is currently on the market more hot home appliances, after buying back, home electric pressure cooker used for a period of time there will always be this or that fault, that should be how to carry out repairs to solve it? The following is my electric pressure cooker repair method for you to organize, I hope to help you.

Electric pressure cooker faults and repair methods

1, the power indicator light, but does not heat

This fault is mainly in the heating plate part of the fault, commonly due to the heating plate has been burned (open circuit).

2, boot a heating for a while, the machine automatically disconnect the power supply, the light is not lit

This failure is mainly the bottom of the pot 145 degrees of thermostat failure, failure. Only heating not to the temperature disconnect the power supply, the temperature drops to power after the replacement of the temperature control on the line.

3, electric pressure cooker float can not rise

Not put the float valve sealing ring, put the float valve sealing ring; lid leakage around the lid, check the lid and lid sealing ring; if not put the lid sealing ring, put the lid sealing ring; if it is a bad float valve, to replace the float valve.

4, electric pressure cooker power control panel no display

power plug and pot socket contact is poor, overhaul the power plug and socket; poor contact with the internal wiring, overhaul the internal wiring; power supply board is damaged, replace the power supply board; display board is damaged, replace the display board.

5, electric pressure cooker float rise after leakage

If the float seal ring sticky food can also lead to air leakage, you need to clean the seal ring; float seal ring wear, replace the float seal ring; float valve is not tightened, tighten the float valve.

Daily maintenance of the pressure cooker

1, after the use of electric pressure cooker, should be washed and dried at any time, the lid should be placed on the body of the pot and do not and the pot together, in order to prevent deformation of the sealing rubber ring, the use of gas leakage.

2, the pot should not be long put in the storage of alkali, salt, soy sauce, etc., in order to prevent corrosion. Residual food sticking to the body of the pot, can be soaked in warm water, scrubbing. Do not use ashes, gravel, etc. to scrub.

3, the lid, the pot and the pressure valve should be properly stored, prevent bumping, touching, so as not to damage the seal of the pot, the loss of the role of the pressure cooker. When the end of the pot should be the main vice handle at the same time, to reduce the pot handle one end of the force, to prevent damage to the pot handle.

The safety devices of electric pressure cooker

1, pressure-limit protection device

Pressure-limit protection device is mainly through the lid of the pot to realize the function of the pressure limiting valve, when the pressure in the pot exceeds the set pressure, the pressure limiting valve will be automatically vented to relieve the pressure.

2, open and close the lid safety device

open and close the lid safety device is mainly through the lid on the float valve to achieve the function, when the lid and the pot body is not buckled in place, the pot can not be pressurized; when there is pressure in the pot, the lid lock can not be opened.

3, temperature-limiting safety protection device

Temperature-limiting safety protection device is mainly through the temperature limiter to achieve the function, when the temperature in the pot reaches the set temperature, the temperature limiter automatically cut off the power supply.

4, over-temperature safety device

Over-temperature safety device is mainly through the over-temperature fuse to achieve the function, when the temperature in the pot exceeds the maximum allowable value, the over-temperature fuse will automatically fuse, permanently cut off the power supply.

5, pressure relief protection safety device

Pressure relief protection safety device is mainly through the electric pressure cooker's own structure to achieve the function, when the pressure in the pot exceeds the maximum allowable value, the lid will automatically exhaust around the pressure relief, to ensure that the phenomenon of the pot will not occur.

6, anti-blocking safety device

The lid exhaust valve has an anti-blocking cover to prevent the exhaust port from being blocked to ensure smooth exhaust.

7. Automatic pressure control

The pressure switch can control the pressure in the pot within a certain pressure range to ensure that the pressure in the pot will not be high.
