Fix a false SUPOR electric pressure cooker E4 fault, after inspection, the pressure switch is not in good contact. Replacement repair, but do not know how to adjust, worry about not repair to the original machine state will explode! Ask the heroes what coup adjustment!!!
The pressure switch is adjusted to the air valve. When the gas is out, it should be broken off. A little gas can be closed and the air valve is broken. Handshake, that's how I got it
Debugging method: remove the plastic bottom cover of electric pressure cooker, the pressure detecting switch of electric pressure cooker replaced, with screwdriver to adjust when the switch is closed completely, just when the counter clockwise N circle, the amount of water in the pot (about 500ML), installed inside the pot and tighten the lid, small iron the exhaust port also should be installed. The electric heating to boil water for a while, see the smoke vapor from the exhaust hole, and for a while, a lot of smoke and steam, issued a hissing sound, then to unplug the power line from the bottom of the pot, carefully put the pressure detecting switch clockwise slowly adjust, immediately stop when the switch is off. Then, on the inner pot of electric heating to boiling water, I saw a slight water vapor vent out, over a period of time to the state of insulation. (picked out on the Internet. I wonder if it's testing.)
E4 pressure switch failure 1. pressure switch contact pressure is lower than 2. 0.04MP wet oxidation is controlled for the first case the oxidation processing clean; second cases had to adjust the pressure switch, the method is as follows: adjustment method of pressure cooker electric pressure switch has two kinds of methods, 1. have pressure gauge: adding an appropriate amount of water into the pot. Cover the pot boil, remove the pressure relief valve on the pressure gauge, such as meter readings to 0.068MP adjust the pressure switch to just disconnect the fixed with glue adjustment screw. 2. have no pressure gauge, do not remove the pressure relief valve, the pressure relief valve to the maximum, so just began to leak, immediately adjust the pressure switch to jump, then clockwise to spin again a little bit on the line. Remember to screw the screws with glue.
