There are the following fault codes:

A, E 1 sensor open circuit:

1. It is possible that the sensor is broken, including leads, plugs and sockets.

2. The weather is too cold and the sensor resistance is too high, which causes the electric pressure cooker to display this code.

Second, E2 sensor short circuit: sensor short circuit fault is rare.

Generally, only a new sensor (room temperature 25 degrees sensor 100K) can be replaced.

Third, E3 overtemperature: The bottom of the pot is too dirty and the temperature is too high.

Fourthly, the E4 pressure switch is out of order.

Matters needing attention in the use of health pot

1, please do not dry-burn.

2. When using, please wait for the water to boil before adding health care materials or flowers and leaves, and stir a little. If sugar is added, please stir until the sugar melts, so as not to sink into the bottom of the pot, causing the bottom of the cup to be black and damaged.

3. Don't cook food below paste powder in the health pot, such as sesame paste, yam powder, coffee, milk powder, etc. To prevent the bottom of the pot from sticking to the bottom of the pot and causing damage.

4. Before use, please confirm whether there is water in the socket and bottom of the health pot. If there is water, please dry it before filling it to avoid damaging the glass.

5. If there is scale in the pot after a period of use, please boil it with acetic acid, citric acid or lemon slices.
