Huangming solar water heater shows what is the fault of E2

It is difficult to determine the reason, because the solar energy brand is different and the instrument is different, and the fault is naturally different! You can refer to the following failures**!

Recommended: "Dr. Sun" solar (first-class energy efficiency, 3C certification), Sancang solar (no need for water level sensing probe and solenoid valve), heating and hot water utilization in rainy weather are fast, and the after-sales rate is also greatly reduced, which saves time and electricity. This model only takes 20-30 minutes to heat up in the absence of sunlight compared to ordinary single-bin solar energy, while the single-bin takes 2-3 hours!

Hello! The meter shows that the E2 Genna sensor is faulty; Minna sensor water level sensor failure: E2 (water level digital tube display);

Huangming solar after-sales is too bad! Don't mind buying this brand.

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. The smoke pipe wind shield is stuck, resulting in unsmooth smoke exhaust;

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

4. 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;

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;

6. 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;

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. Check whether the inlet pipe switch is not fully opened, and the water heater is not filled with water;

2. Whether the inlet and outlet pipes of the machine are reversed;

3. Check whether there is a problem with the motherboard or sensor;

The water heater showing E2 is an error indicating that the water heater is malfunctioning**, and there are three 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.

Solution: 1. The set temperature and indoor and outdoor ambient temperature are too low (generally lower than 22 degrees), and the air volume is too low, and the air conditioner is protected normally (the temperature will be lifted after the temperature rises).

2. Lack of fluoride (see if the thin pipe of the air conditioner and the indoor heat exchanger are frosted, if frosted, then it is, find after-sales leak detection and fluoride), if there is a condition, measure the system pressure.

3. The filter screen or indoor heat exchanger is dirty, resulting in low air volume, and the system cannot exchange heat in time, resulting in low temperature of the indoor coil, just clean the filter screen or indoor heat exchanger.

4. The failure of the fan and related circuits causes the air volume to be low, and the system cannot exchange heat in time, resulting in the temperature of the indoor coil being too low, so find after-sales maintenance.

Huangming solar water heater shows E2, which means that the water heater has a water temperature level sensor fault, or a thermona sensor fault, and the thermona sensor needs to be replaced. In this case, it is necessary to contact the after-sales service for maintenance, and it is not recommended that the user disassemble and solve the problem by himself. You can contact the local Huangming after-sales outlets, or you can log in to the Huangming Climate Improvement Official** to consult the official customer service of Huangming.

Precautions for the use of Huangming solar water heater:

1. It is strictly forbidden to operate the electrical part with wet hands, cut off the power supply of the Side thermal auxiliary system and antifreeze belt before bathing, it is strictly forbidden to use the leakage protection plug as a switch, and it is strictly forbidden to start the electrical part frequently.

2. When hot water is found in the cold water pipeline, it should be repaired in time to prevent the cold water pipeline from being scalded.

3. When the indoor temperature is lower than 0, the water in the pipeline should be emptied and the water discharge valve should be kept open to prevent freezing damage to the pipeline and indoor copper fittings.

Summary. Hello, the solar water heater shows that E2 is a sensor failure, common reasons: 1. The sensor is damaged and needs to be replaced with a new sensor; 2. The line is loose and needs to be reconnected.

Hello, the solar water heater shows that E2 is a sensor failure, common reasons: 1. The sensor is damaged and needs to be replaced with a new sensor; 2. The line is loose and needs to be reconnected.

Hello The common reasons and maintenance of solar water heater E2 are as follows: 1. The reason why the electric water heater will display E2 is that the water temperature is too high. At this time, the first thing to check is the water inside the water heater, usually, if the water in the electric water heater is not full or it starts to work before the water starts to enter at all, the electric water heater will show E2, so checking the water is the first step of maintenance.

2. Secondly, the maintenance of the electric water heater E2 also requires us to check the inlet pipe and outlet pipe of the machine, if the inlet pipe is installed in reverse or the outlet pipe is not installed at all, then it is necessary to respond in time, in addition, it is necessary to check the waterway connection, because the wrong connection of the waterway will also cause the electric water heater to display E2, if it is this problem, you only need to connect the waterway to the right. 3. Finally, when dealing with the problem that the electric water heater displays E2, we also need to check the control panel of the electric water heater, because when there is a problem with the control panel of the electric water heater, the electric water heater will also display E2, so the control panel of the electric water heater can be replaced during maintenance.

If the water heater has an E3 fault, it means that the temperature in the power heater is relatively high, so that the water heater stops running. This situation is usually that the water heater has not been cleaned for a long time, and the dirt accumulated inside is particularly coarse, so that its heat conduction is greatly reduced. At this time, the power supply should be disconnected first, and then the water supply valve should be closed, and the sewage valve should be opened in Naohe Town, and the sewage valve should be closed after the sewage flows out. ”

1. The overheating protection is faulty.

Solution: Reset the overheating protection;

2. The fuse burns out.

Solution: It is better to replace the fuse;

3. Hall sensor.

Whether it is stuck or not. Solution: Clean up the debris;

4. There are stolen goods in the temperature measuring head.

Solution: Clean the stolen goods of the temperature measuring head;

Summary. Hello, one possibility is that your water heater does have leaks or water seepage, please pay attention to observation, especially at the faucet or pipe junction to see if there is any dripping and seepage. The second possibility is that the newly installed water level gauge is often in a floating state when it is installed, and the measured water level is often "very empty", and when it reaches "80", the water level will show "100" when it is slightly watered, and the water level at this time is extremely unstable, and it will return to "80" immediately after a little water.

In addition, the water level is in a rolling state when the water is on the water, and the measured water level is often "virtual" at this time, and the water level will naturally decrease after a period of time when the water level tends to stabilize. There is also a situation where the water temperature decreases at night, and the water level also decreases according to the principle of thermal expansion and contraction. You can judge the problem with your water heater based on the above two possibilities.

Or, unplug the latch for a while and see if it works. 珞珞
