E2 is an error that indicates a malfunctioning water heater**.
1. 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, it means that the dry burning is overheated, the dry boiling without water, the water pressure is low for water flow detection, and the filter screen is blocked.
2. The following inspections should be carried out step by step:
1. The air inlet is taken by raw meal.
and other foreign bodies are blocked, resulting in a decrease in air intake.
2. The smoke pipe anti-backwind baffle is stuck, resulting in poor smoke exhaust.
3. After the fan or fan starting capacitor is damaged, the wind speed does not rotate, resulting in the flame extinguishing.
4. Condenser of condensing model.
The drain hole is blocked, resulting in the accumulation of condensate in the condenser, and the flue gas cannot be discharged, resulting in E2 failure.
5. 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.

The occurrence of E2 is due to abnormal wind pressure or fan failure. 1. When the flue is blocked or the flue resistance is too large, the wind pressure switch will be activated and the program will be interrupted; Reliable plugging, no air leakage, no plugging errors, etc.; 2. When the fan fails, the speed is too low or stopped, and the program is interrupted. Check whether the connection line between the fan and the main control board is plugged in reliably, whether the fan is damaged, whether the fan is stuck, etc.
Check the water outlet of the hot water faucet, if it is small, it should be a problem caused by insufficient water flow.

Gas water heaters.
The occurrence of E2 may be due to the following reasons: 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 the dry boiling is overheated, the dry boiling without water, the water pressure is low for water flow detection, and the filter is blocked.
The following tests should be performed gradually:
1. The air inlet is taken by raw meal.
and other foreign bodies are blocked, resulting in a decrease in air intake.
2. The smoke pipe anti-backwind baffle is stuck, resulting in poor smoke exhaust.
3. After the fan or fan starting capacitor is damaged and the silver is raised, the wind speed does not rotate, causing the flame to go out.
4. Condenser of condensing model.
The drain hole is blocked, resulting in the accumulation of condensate in the condenser, and the flue gas cannot be discharged, resulting in E2 failure.
5. 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.

1. On behalf of the gas water heater.
If the wind pressure is abnormal or the wind pressure switch is faulty, first of all, if the wind is blowing outside, the outdoor air pressure will be greater than that indoors, which will lead to the E2 alarm of the gas water heater, and you can wait for the wind stop pressure to return to normal before checking whether the problem is solved. 2. It may be that the position of the air inlet is blocked by a foreign object. 3. The starting capacitor of the fan fails to start normally due to failure or aging.
Suggested solutions: 1. Wait for the indoor and outdoor pressure to return to normal and check whether the problem is solved. 2. Check the position of the gas water heater inlet, 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. 3. Disassemble the shell of the gas water heater, find the starting capacitor of the fan, and use an ohmmeter and an electric pen.
If the capacitor is faulty, or can not work normally, you need to replace a new capacitor, and re-fix the capacitor with soldering. 4. The gas water heater needs to install a safety valve to avoid the occurrence of danger.

In most gas water heaters**, e2 indicates wind pressure or fan failure. According to my maintenance experience, wind pressure and fan failures are common in the following situations:1
If the air pressure switch is faulty, just replace the air pressure switch. 2.The heat exchanger has heavy carbon deposits, and the failure disappears after cleaning the tank.
3.In rare cases, there is a real problem with the fan or turbine, but the proportion is very small. 4.
There are also individual hidden faults, which require repeated exploration by experienced after-sales sites to find the problem.

The failure of the gas water heater E2 represents the abnormal air pressure in the water heater or the failure of the fan, which may be caused by the following reasons: 1. Most of the faults are caused by the blockage of foreign bodies at the air inlet, resulting in the reduction of the air inlet volume. 2. It may be caused by the fact that the wind speed does not rotate and the flame is too small to extinguish after the starting capacitor of the fan is damaged.
The gas water heater is mainly composed of valve body assembly, main burner, small fire burner, heat exchanger, safety device, etc., and also includes the flue of flue water heater and the strong discharge device of strong discharge water heater. The valve body assembly controls the working procedure of the entire water heater, which includes water valves, air valves, micro switches and igniters. When installing a water heater, valves should be installed on the inlet pipe, outlet pipe, and gas pipe.

<> "1. What is the reason why the gas water heater shows E2?
The brand and model of gas water heater are different, and the meaning of E2 is also different. Generally speaking, it means that the water heater has failed, and there are three reasons for it:
1. There is a problem with the fan of the air conditioner, resulting in the failure to operate normally.
2. The fan switch of the air conditioner is damaged, or the inside of the flue is blocked, resulting in the inability to celebrate or operate normally.
3. If there is a problem with the circuit of the fan, E2 will also be displayed. Common phenomena include the water heater drying out, the filter clogged, or the water pressure of the water flow being too low.
2. What is the correct way to use the gas water heater?
1. You need to fill the gas water heater with water, and then adjust the temperature to about 50 degrees, and then turn on the power. Dry boiling can be avoided. When the temperature of the water heater reaches the set value, turn the switch to the left for hot water, and turn to the right for cold water.
2. When turning on the hot and cold water faucets, it is necessary to turn the opening and collapsing sail in the direction of cold water first, and then slowly turn to the hot water side to avoid scalding. When it is closed, turn to the cold water area before turning it off.
3. Before using the water heater, you also need to read the instructions for use and see the correct way to use it. Then follow the instructions for proper use. If it is a metal pipe, it is easy to age, and if it is a rubber pipe, it will age after a long time.
4. When using the gas water heater daily, it is also necessary to check whether the pipeline is damaged and leaking, and it needs to be dealt with in time to avoid affecting the safety of your own home.
First of all, Wanhe gas water heater is better. Wanhe Group was established in August 1993 and is located in Shunde, the hinterland of the Pearl River Delta. Now it has one of the largest sterilizer production bases in Asia and a large-scale, first-class water heater production base in China, with an annual production capacity of more than 2 million water heaters and sterilizers, and the products sell well all over the country and Europe, America, Southeast Asia and other regions. >>>More
The efficiency of gas water heaters is usually about 90% (condensing type can even exceed 100%), and the efficiency of electric water heaters is generally above 90% (but considering the primary energy power generation efficiency is 45%, the primary energy efficiency of electric water heaters is about 40%), the air energy water heater is an air source heat pump, and the heating coefficient is generally about 5 (which can be approximated as the efficiency is 500%), and it is estimated that it can reach 3 under low temperature conditions in winter. The overall efficiency is about 5% based on a heating coefficient of 220%. >>>More
You have to check what the fault is according to the indication on the water heater shell, generally E1 is the main valve fault of the water heater. Ask the master to repair it.
I think electric water heaters are better, now the gas is getting higher and higher, the cost of using gas water heaters is relatively high, and the energy consumption cost of electric water heaters is relatively low, and the cost will be more cost-effective.
With the improvement of living standards, everyone's requirements for the quality of life are getting higher and higher, so more attention is paid to the selection of gas water heater experience functions to improve the overall household hot water use experience. >>>More
