What does E2 mean when there is an E2 in the water heater, how to solve the E2 failure

What is the reason why a household gas water heater shows e2**? Is the water heater not being used properly or is it broken?

Gas Water Heater E2 Failure Cause:

1.Condenser failure

The failure of the condenser of a water heater is different from that of an air conditioner condenser, and such problems are most likely caused by a clogging of limescale. If you want to deal with this situation, you must first drain the water inside the water heater, and it is best to clean the water heater regularly, otherwise this kind of problem will occur after a period of use.

2.The air inlet is clogged

Everyone may have heard the term "water intake", but the term "air intake" is relatively untouched. So what is the intake air volume? Once the air intake is too large, the dirt brought by the water heater during use will become more, resulting in the blockage of the water heater inlet, and the water heater will display E2 fault ** to remind you that there is a problem.

Therefore, during use, pay attention to the air intake volume of the water heater, not too much.

3.The fan circuit is faulty

If the Haier gas water heater shows E2**, it means that the wind pressure or fan is faulty, and you need to check whether the ventilation module of the water heater is abnormal. Once the starting capacitor of the fan is damaged, the wind speed will not rotate will cause the flame to go out and the water heater will fail.

Usually we encounter this situation will be less likely, and we have relatively little understanding of this aspect, so if there is a problem with the fan circuit, it is best not to solve it by yourself, but to find a professional water heater maintenance personnel to come to the door for maintenance, so as not to cause other problems due to improper operation.

About the gas water heater E2 failure** That's it, I hope it will help you, don't panic when there is a problem with the water heater, find the cause of the failure, and seek the corresponding solution.

The water heater shows E2, which means: the water temperature in the water heater is too high; Ignition, turn off. The water temperature in the water heater is too high

When the temperature reaches 50, the heater is immediately cut off and the display flashes to indicate fault**e2. Extinguishing the fire after ignition: In many cases, the reason why the fire cannot be ignited is because the hot water pipeline is blocked due to the scaling of the waterway, resulting in a large back pressure on the waterway flow.

Maintenance method for excessive water temperature in water heater:

1.First of all, check whether the water heater is not filled with water or if it starts heating without water;

2.Check whether the inlet and outlet pipes of the machine are installed in reverse or without the water pipes, or the user's water channel is connected incorrectly;

3.Replace the control board to see if it can be solved;

Ignition after extinguishing maintenance method:

It is recommended to clean and descale immediately, you can buy a set of gas water heater online without removing the scaler, use it to inject descaling agent into the water heater to clean the inside of the water heater and the inside of the hot water pipeline, the operation is simple and convenient, and it can be cleaned regularly after use, when this problem can be avoided again.

It's a pleasure to serve you.

1. For gas-fired water heaters, E2 indicates the wind pressure or the failure of the fan, which may be caused by the following reasons. 1. The air inlet is reduced due to the blockage of foreign bodies. 2. It may also be that the smoke pipe windshield is stuck and the smoke exhaust is not smooth.

3. Or after the fan or fan starting capacitor is damaged, the wind speed does not rotate, resulting in the flame extinguishing. 4. If it is a condensing model, it may be due to the blockage of the drain hole of the condenser, resulting in the accumulation of condensate in the condenser, and the flue gas cannot be discharged.

5. It is also possible that the 4th or 5th nozzle on the right side of the distributor is blocked, resulting in a fault alarm caused by the extinguishing of the flame when the fire is converted. 6. You can also check the smoke outlet of the machine with a smoke pipe to check whether there is a large amount of carbon deposit, and the liquefied gas model is easy to disassemble and clean the machine due to carbon deposit due to poor combustion. 2. For electric water heaters, E2 means that the water temperature in the water heater is too high, and the thermocouple will protect it and automatically cut off the power supply.

1. You can check whether the inlet pipe switch is not fully turned on and the water heater is not filled with water.

2. If it is a newly installed machine, it can also be whether the inlet and outlet pipes of the machine are installed backwards. 3. You can also check whether there is a problem with the motherboard or sensor.

1. E2 is an error that indicates that the water heater is malfunctioning**. There are two forms: one is an electric water heater, and the other is a gas water heater.

2. The electric water heater generally indicates that the fan system of the water heater is faulty. Possible causes: 1. The fan itself is faulty and cannot be operated.

2. Wind pressure switch or flue blockage. 3. There is a problem with the fan circuit. Gas water heaters generally indicate that dry boiling is overheated, dry boiling without water, water flow detection water pressure is low, and the filter screen is blocked.

This should be found in the manual.

The fault code corresponds to the fault code.

Faults set by different manufacturers.

The code is different, and the specific instructions shall prevail.

E2** is an ignition failure fault. It should be resolved according to the cause of the occurrence of e2.

1. The smoke pipe is too long.

Solution: The smoke pipe of the wall-hung boiler is too long, which will cause the internal exhaust gas to be discharged normally, and the overheating inside the wall-hung boiler will start the overheating protection of the system. Just reduce the length of the pipe.

2. The water tank is blocked.

Solution: The water tank is blocked, the hot water can not flow out normally, and the wall-hung boiler will overheat, there should be too many foreign bodies inside, and the water tank needs to be cleaned at this time.

3. The temperature at the thermocouple is too high.

Solution: If the temperature near the thermocouple is too high, the thermocouple will start the protection device, and the wall-hung boiler fault will be displayed.

4. The thermocouple is damaged.

Solution: If the thermocouple fails, it cannot correctly reflect the temperature of the wall-hung boiler, so the wall-hung boiler will automatically report an error, as long as the thermocouple element is replaced.

5. The water control switch is faulty.

Solution: In addition to the E2 occurrence of the wall-hung boiler because of thermocouple protection, the failure of the water control switch will also lead to the failure of E2, such as the micro switch fork will not be reset, as long as the water control switch is adjusted.

1. It may be because the temperature of the water heater is too high, just lower the water temperature appropriately. 2. The air pressure switch of the water heater is faulty and needs to be replaced. 3. It may be because the temperature probe of the water heater is damaged and needs to be replaced.

4. It may be caused by blockage, and the debris needs to be removed. 5. If the main board of the water heater is faulty, it is necessary to find a professional maintenance personnel to test it or replace the main board of the water heater. 6. If the water heater component fails, it needs to be detected and replaced.

Popular science knowledge: 1. Use electric water heaters.

When the water temperature reaches the set value, the indicator light goes out, which means that the power is cut off. The indicator light will be on and off, indicating that the water heater is automatically insulated. 2. The electric water heater needs to be filled with water first, and then heated by electricity, and can be used after preheating.

If you experience a drop in water pressure or a sudden water outage, it is best to turn off the power. 3. Electric water heaters are equipped with faucets and return flow devices, usually blue for cold water and red for hot water. 4. When filling the water, you need to open the water outlet, and wait for the air in the inner tank to be completely discharged before checking whether the water has been filled.

5. The power supply must be cut off before emptying.

1. If you are using a gas water heater, E2 indicates the wind pressure or fan failure, and you need to check the working status of the ventilation module of the water heater; If you are using an electric water heater, E2 means that the water temperature in the water heater is too high, and the thermocouple will automatically cut off the power supply, and you need to check the water supply and sensor status of the water heater.

2. For gas-fired water heaters, E2 indicates the wind pressure or the failure of the fan, which may be caused by the following reasons: the air inlet is blocked by foreign bodies, resulting in a decrease in the air intake; It may also be that the smoke duct wind shield is jammed and the smoke exhaust is not smooth; Or after the fan or fan starting capacitor is damaged, the wind speed does not rotate, causing the flame to go out; If it is a condensing model, it may be due to the blockage of the drain hole of the condenser, resulting in the accumulation of condensate in the condenser and the flue gas cannot be discharged; It is possible that the 4th or 5th nozzle on the right side of the distributor is blocked, resulting in a fault alarm caused by the extinguishing of the flame during the fire conversion; You can also check the smoke pipe of the machine to check whether there is a large amount of carbon deposit, and the liquefied gas model is easy to disassemble and clean the machine due to carbon accumulation due to poor combustion.

3. For electric water heaters, E2 indicates that the water temperature in the water heater is too high: the thermocouple will automatically cut off the power supply for protection; You can check if the inlet pipe switch is not fully turned on and the water heater is not filled with water; If it is a newly installed machine, it can also be whether the inlet and outlet pipes of the machine are installed in reverse; You can also check if there is a problem with the motherboard or sensors.

In the process of using the water heater, many people don't know what it means when they see the numbers displayed on the LCD screen of the water heater, let alone how to solve it, such as E2, so what is the solution to the water heater E2 failure?

1. What is the solution to the E2 fault of the water heater?

1. Check whether the fan has been turned on, if the fan is not opened, it may be that the starting capacitor of the fan has burst, and the parts corresponding to the model need to be replaced immediately. 2. It may be because the flue is blocked, and the blockage inside the flue needs to be cleaned up. 3. Outdoor fans exceeding level 4 will also lead to E2 failure, you can change the direction of the exhaust port, or directly install a draft shield.

2. Reasons and solutions for gas water heaters that are not good for ignition.

1. When a certain accessory of the product fails, it will cause the water heater to fail to ignite, but the quality of the product components of many brands is relatively good and it is not easy to be damaged, so the water heater is not good to ignite generally because of the scaling of the waterway.

2. If all the hot water faucets are turned on in the near future, the hot water pressure will be very small, in this case, the water vapor linkage device of the water heater will mistakenly think that the hot water faucet is not opened, so that the gas channel will be closed, resulting in the water heater being unable to ignite. In this case, it is necessary to check the applicable water supply pressure range marked on the water heater, and then control the water supply pressure within this range.

3. The water heater is equipped with a dry battery, and when the dry battery voltage is insufficient, the water heater will be bad or even unable to ignite, and it is easy to cause deflagration, so when encountering this situation, it is necessary to replace the new dry battery immediately to ensure that the dry battery has sufficient voltage.

Summary: What is the solution to the water heater E2 fault is introduced here, once the water heater fails, it is recommended that you directly find a professional for maintenance, which will be more secure, but also to prevent secondary damage to the water heater.

1. Fault **e2

What it means: The ignition goes out halfway through, the water heater detects a flame, but then disappears again, and the machine shows e2. The following tests should be performed gradually:

2. The air inlet is blocked by foreign objects such as raw meal belt, resulting in a decrease in air intake.

3. The smoke pipe anti-backwind baffle is stuck, resulting in poor smoke exhaust.

4. After the fan or fan starting capacitor is damaged, the wind speed does not rotate, resulting in the flame extinguishing.

5. The drain hole of the condenser of the condensing model is blocked, resulting in the accumulation of condensate in the condenser, and the flue gas cannot be discharged, resulting in E2 failure.

6. The 4th or 5th nozzle on the right side of the distributor is blocked, resulting in the flame extinguishing and E2 fault when the fire is converted.

7. Open the smoke pipe and check the smoke exhaust port of the machine to check whether there is a large amount of carbon deposit, the liquefied gas model is easy to accumulate carbon due to poor combustion, and it needs to be disassembled and cleaned, and the pressure of the liquefied gas source is checked.

8. If it has been used for a long time, there is a possibility that Hengtong is blocked by scale, which causes false alarms. If the hot water flow is obviously small, it should be a problem of scale blockage, buy a set of gas water heater online without removing the scale, inject Bi Tsai into Huitan descaler should be solved.

1. E2 represents a gas water heater.

The abnormal wind pressure may be caused by the location of the air inlet being blocked by foreign objects. 2. It may be caused by the installation of the pipe at the water inlet. 3. It may be that the wind shield of the smoke pipe is stuck and the smoke exhaust is not smooth.

4. It may be caused by damage to the fan or the starting capacitor of the fan, so that the wind speed does not turn and the flame is extinguished. Brother slippery.

Suggested Treatment:

1. In the state of not starting, first unplug the exhaust flue and then turn on the water heater to see if E2 is still displayed, if it is not displayed, the flue is blocked and only needs to be cleaned up. Check the location of the gas water heater inlet to find the blocked foreign object and use a hose or vacuum cleaner.

Clean the brush and dredge the water inlet to ensure that there is enough gas to enter the gas water heater to ensure that it can be fully burned.

2. Check whether the switch of the inlet pipe is fully opened, whether the water heater is filled with water, if the newly installed machine is also to check whether the inlet and outlet pipes are installed in reverse, and change the problem in time.

3. Open the cover plate of the gas water heater, find the position of the fan, check whether the fan is running normally, if the fan cannot operate normally, you need to check whether the starting capacitor of the fan is faulty, you can use the ohmmeter to measure whether the starting capacitor is smooth, if the fault is out, you can replace the starting capacitor to see if the problem is solved. If the fan still fails to start after replacing the starting capacitor, contact a professional maintenance personnel to repair and replace the fan to see if the problem is solved.
