What happened to the E8 in the Hongyan automatic kettle?

Induction. Fault**E8 indicates the key malfunction protection function, when the machine recognizes that a key is continuously closed for more than 1 minute, the digital tube displays "E8", and the alarm is carried out, and the alarm state cannot be automatically exited, and the alarm state can be exited manually by shutting down. When adjusting the time, you may press and hold the [Hour] or [Minute] button, but you still need to give an alarm after 1 minute (if E8 is still displayed, please go to the maintenance network to check).

Common faults of induction cooker** and cause of failure:

1.Internal circuit failure.

2.No pots or pans (material, size, shape, position) are not suitable;

3.Poor heat dissipation inside the machine or temperature sensor inside the machine.

Fault; 4.The grid voltage is too high;

5.The grid voltage is too low;

6.Ceramic plate temperature sensor breakage;

7.The pot is dry boiled and the temperature of the pot is too high;

8.The inside of the machine is damp or dirty, causing the keys to close.

Although it is confirmed that the demand curve arises naturally from the theory of consumer choice, the derivation of the demand curve itself is not a theory that proposes consumer behavior. Simply determining how people react to change doesn't require a rigorous analytical framework. However, consumer choice theory is extremely useful.

As we will illustrate in the next section, we can use this theory to more deeply determine the factors that determine family behavior.

Instant Answer Draw budget constraint lines and indifference curves for Pepsi and pizza. Illustrate what happens to the budget constraint line and consumer optimum when pizza** rises. Use your graph to divide this change into income effects and substitution effects.

Four applications. Now that we've established the basic theory of consumer choice, we can now use it to illustrate four questions about how the economy works. However, since each problem involves family decision-making, we can address these issues with the consumer behavior model we just proposed.

Are all demand curves sloping to the bottom right?

In general, when an item** goes up, people buy less. Chapter 4 refers to this normal behavior as the law of demand. This pattern manifests itself in the demand curve sloping to the lower right.

However, as far as economic theory is concerned, the demand curve also sometimes slopes to the upper right. In other words, consumers sometimes defy the law of demand and buy more when one item rises. To illustrate how this can happen, look at Figure 21-12.

In this example, the consumer buys two items – meat and potatoes. Initially, the consumer budget constraint line was a straight line from A to B. The best advantage is c.

When the potato ** rises, the budget constraint line moves inward and is now a straight line from A to D. Now the best thing is e. It is important to note that the rise in potatoes has led consumers to buy more potatoes.

Summary. Hello Automatic water kettle display e8: most of the temperature sensor is bad.

The automatic kettle shows that the e8 is broken???

Hello Automatic water kettle display e8: most of the temperature sensor is bad.

1. Internal machine dust removal treatment method: 1. Clean the filter screen, use a toothbrush, a fine row pen, wet wipes, etc. to clean the dirty parts of the air outlet, fan roller impeller, and evaporator after lifting the filter, and remember not to cause damage. 2. After cleaning, it is best to pour a few cups of water along the evaporator, rinse the sink by the way, to prevent the residue and dirt from blocking the drain pipe.

Cleaning and dust removal method of the external machine: 1. Unplug the air conditioner power, connect a water pipe for car washing, use tap water to rinse up and down, use a plastic bucket to wash water without conditions, prepare a brush with a handle (a few yuan a, a lot of hardware stores), brush the aluminum wings up and down while washing, and remember not to deform the aluminum wings with a sail cover. 2. Don't doubt that the circuit will be wet, the outside unit of the air conditioner is fine in the wind and rain, but some air conditioners with poor quality and materials will rot quickly.

2 In the upper right corner of the outside of the water heater, pat it vigorously three or four times, and then start it, you may be able to use the clear answer. 2.Remove the clogged debris in the flue, shorten the smoke pipe, reduce the angle, and tighten the windproof device.

3.Use an abrasive cloth to remove the oxide layer or replace the air pressure switch assembly. ⑨

The automatic kettle shows that the e8 is broken???

The automatic kettle shows that the e8 is broken??? Hello dear, the automatic kettle shows what is the fault of E8: (1) Poor line contact, overhaul socket and wiring.

2) If the sensor or other components are damaged, send it to the repair department for repair. 2. If it can work normally, it will only display abnormality: if the vertical display board is damaged, it will be used or sent to the repair department to replace the display board.

The automatic water kettle shows E8: most of the temperature sensors are bad. The working principle of the electric kettle is that the water vapor generated when the water boils deforms the bimetal sheet of the steam temperature sensing element, and this deformation pushes the power switch to power off through the lever principle.

It is not self-resetting when it is powered off, so the kettle will not automatically reheat after the power is off. Electric kettle Nahoda was born in Chicago in 1891. With the development of science and technology, fast, safe, convenient, and full use of energy have increasingly become the main characteristics of the kettle, and the British people who love tea have fallen in love with it since then.

In the 21st century, it has become a bestseller in the world. The electric kettle adopts steam intelligent induction temperature control, which has the functions of automatic power-off after water boiling and anti-dry-burning high-power. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!
