Fault code: C6

Fault content: pressure switch malfunction

Fault phenomenon: pressure switch contacts have stains

Fault causes and troubleshooting methods:

1, pressure switch contacts have stains. Wipe off the dirt with a clean cloth.

2, pressure switch conductive place has obvious rust. Use sandpaper to remove the rust. But it will only last for a while, because the rusted place is easy to rust again, the best way is to replace the pressure switch.

3, after repairing the pressure is adjusted too low below 10Kpa). Need to be adjusted to 50~60kpa according to the standard .

4, pressure switch wire and power board connection contact is poor. Need to re-weld or replace.

Common computerized electric pressure cooker fault code solution

E1, E2 sensing failure

E3, E4 sensing failure

1, there is a E1/E2 fault code

The fault first to measure the sensor (i.e., the sensor in the center of the heating plate), to see if it is disconnected or open, if normal, then you can dismantle the Control board, to see whether the moisture, because the moisture may be to the error message. Another should observe the motherboard circuitry of the soldering points will be de-soldered to the error message.

2, E3/E4 error code

E3/E4 refers to the signal switch failure (i.e., pressure switch failure) The most common failure is due to the power supply board block in the line of soldering points caused by desoldering. This fault can be power board and control pole in the solder joints check to find out. In addition, the pressure switch itself is out of order, or the control pole moisture error signal. (Note: Remember to disconnect the two ends of the connection line when measuring the pressure switch)

3, the display of the digital word missing picture

This fault is the host of the display around the soldering points desoldering to, plus welding is OK.

4, power on, the display does not light, but can hear the relay action sound, the pot has been heated, can not control.

This fault is also due to the solder joints of the virtual welding or desoldering.

5, the control is completely normal, the display is normal, but not heating.

(1) is the relay is burned out, not action, replace it can be.

(2) is the solder joints de-soldering, signal transmission can not - add welding!

(3) the heating plate has been less bad, need to change the new one.
