The solar water heater does not display the temperature anymore, and the water level is also display

It may be that there are several situations in which you can take a look for yourself, if it still does not appear, you need to ask a professional master to come to repair.

1. The battery is dead.

2. The connection line is damaged.

3. The temperature probe in the water tank is damaged or the joint is damaged.

4. There is a problem with the internal circuit of the measuring and control instrument.

5. The sensor is broken, the probe is fine, you can take the probe out and sand it.

6. The failure of the instrument display (if the water level and time on the meter and the water function are normal, it is not a problem) or caused by the failure of the temperature probe.

7. Test the temperature of the water first, if the temperature is very high, it is the fault of the sensing device, if it is still at room temperature, it is the fault of electric heating or the failure of the leakage protector.

This phenomenon can be caused by a faulty instrument or a faulty sensor. Try to change a good sensor first, if it doesn't work, the meter will fail. For more details, please visit "Solar Home" to check out the relevant posts.

It's bad and good, it seems that there is a problem with the data cable, or there is a problem with the temperature sensor.

Solar water heater controller can not display the water level of the situation analysis and elimination method:

First, the water level sensor in the water tank is broken, or the sensor signal line is open to check and troubleshoot the method.

Pull out the water level and water temperature sensors in the tank of the solar water heater, check whether their appearance is damaged, whether the lead wire has been disconnected, if there is an abnormal situation, it should be replaced with a new sensor, and make sure that the connection with the socket inside the controller is correct;

Second, the display screen of the controller is fixed loose or the display screen is broken.

Carefully check and analyze the specific situation of the circuit and display screen of the controller, and if any abnormalities are found, the controller should be replaced with a new one;

Third, the tap water is stopped, the water pipeline is blocked or the valve is closed, and the water tank is not watered for inspection and treatment

Find out whether the tap water can supply water normally, check the water pipeline, remove the solenoid valve dirty blockage, detect whether the power output of the controller is normal, and take corresponding measures to eliminate the problem if there is a problem.

Are these checking wires for this water gauge broken? That is, there is no open road, and there is to check whether this water level gauge is good, if you don't know, then you can only find a professional to check.

Reasons why the solar water heater controller can't display the water level and how to solve it:

1. The water level and water temperature sensor in the original water tank is damaged or the signal line is broken, and the water level and water temperature sensor in the water tank are pulled out, and the signal line between the control instrument is detected.

2. There is no water in the water tank to check whether the tap water supply is normal, the water supply channel of the solar water heater is cleared of dirty blockage, and the water supply valve is opened to ensure that the water is connected;

3. Check the circuit in the controller if there is a fault, test the voltage of each key point, replace the faulty components, ensure the power supply output of the solenoid valve, and automatically connect the water under the condition that the tap water supply is normal.

Dear, hello, about the solar water heater does not display the temperature, first check whether the battery is dead, or the connection line is damaged, or it may be because the temperature probe in the water tank is damaged or the connector is damaged and there is a problem with the circuit in the meter. It is also possible that the sensor is broken and the probe is fine, so you can try to take the probe out and sand it. In addition, it may also be caused by a malfunction of the meter display, (if the water level and time of the meter and the water supply function are normal, it is not a problem) or a malfunction of the temperature probe.

What's wrong with my solar water heater not showing temperature?

Dear, hello, about the solar water heater does not display the temperature, first check whether the battery is dead, or the connection line is damaged, or it may be because the temperature probe in the water tank is damaged or the connector is damaged and there is a problem with the circuit in the meter. It is also possible that the sensor is broken and the probe is fine, so you can try to take the probe out and sand it. In addition, it may also be caused by a malfunction of the meter display, (if the water level and time of the meter and the water supply function are normal, it is not a problem) or a malfunction of the temperature probe.

Therefore, first test the temperature of the water outlet, if the temperature is very high, it is a failure of the sensing device, if it is still at room temperature, it is an electric heating failure or a leakage protector failure.

It just doesn't show the temperature, everything else is normal.

The probes are all new.

Dear, it is estimated that there is a problem with the temperature sensor, so you need to consider replacing a new probe.

Dear, it should be the temperature sensor faulty.

Summary. Hello dear!

The temperature reason is not displayed.

1. The water temperature sensor is faulty, when the water temperature sensor is faulty, the temperature signal cannot be detected, so the water temperature cannot be displayed; It needs to be solved by replacing the sensor;

2. When the signal line of the water temperature sensor is broken, the temperature signal cannot be transmitted to the instrument, so the temperature cannot be displayed; It needs to be reconnected to the signal line to solve the problem;

3. The instrument temperature acquisition unit is faulty, and the temperature value cannot be collected and displayed when the instrument temperature acquisition circuit is faulty; The meter needs to be replaced;

4. When the instrument display is faulty, and the temperature display module is faulty, the collected temperature value cannot be displayed accurately, resulting in the display error or no display, and the instrument needs to be replaced.

5. Faulty temperature sensor or poor line contact.

6. The instrument display is faulty (if the other functions of the instrument are normal, it can be judged that the temperature sensor is basically faulty).

What is the reason why the water temperature of the solar water heater is not displayed?

Kiss! Glad to serve you! I'm Daxin, please wait patiently for 2 minutes, I'm sorting out, I'll answer for you right away, and please don't end the consultation!

Dear, what should I do if the water heater doesn't show temperature? 1. Replace the temperature sensor or line maintenance. 2. Replace the instrument.

Hope mine is helpful to you!

These instruments, sensors, etc. that I used before are these failures, so I think there is a failure in these accessories, and the new meters, sensors, solenoid valves, etc. I bought today are complete, but the temperature is still not displayed.

Dear, the solar water heater does not display the temperature because there is a problem with the temperature control probe of the temperature display! If the solar water heater is used for a long time, there will be water fouling, which will often cover the probe, which will cause the solar water heater not to display the temperature or the display is inconsistent with the actual situation, the meter display failure, (if the water level and time on the meter, the water function is normal, it is not this problem) or the temperature probe is faulty.

Dear, if it is still at room temperature, it is an electric heating failure or a leakage protector failure, if necessary, you need to find a professional to clean it.

The solar water heater does not display the temperature, and that is because there is a problem with the temperature control probe of the temperature display! If the solar water heater is used for a long time, there will be water quality fouling, which will often cover the probe, which will cause the solar water heater not to display the temperature or the display of the erector is inconsistent with the actual situation. If necessary, it is necessary to find a professional to clean it.

The reason why the temperature indicator of the solar thermal water generator does not have the temperature is not displayed: 1. The microcomputer automatic measurement and control instrument is broken, and the microcomputer automatic measurement and control instrument is replaced. J Lianna 2, the display screen of the microcomputer automatic measurement and control instrument is broken, and the display screen is replaced.

3. The power supply of the microcomputer automatic measurement and control instrument is gone, check the power supply. 4. The water level switch is broken, replace the water level switch. 5. Line fault, check the line.

The new one I just bought is replaced, and the water temperature is not displayed, and there is no middle two squares of the water level.

Where is the water level switch?

The sensor is under the upper cover, a round iron coarse kettle-shaped, connected to a thin plastic pipe below, the switch to the rock Chaling water has not been touched, under the connection to the water inlet pipe, it is best not to repair it yourself, you can first see from the bottom to see if the plastic pipe with the thickness of a little finger is broken.

You send ** to see.

Summary. Kiss, there may be the following reasons: 1The battery is dead and needs to be replaced with a new one.

2. The internal circuit has aged due to the problem of service life, please replace it in time. 3. The temperature sensor in the water tank is damaged or the joint is damaged, and the temperature sensor head needs to be replaced in time. 4. The sensor is broken, and the probe is crystallized!

You can take the probe out and wipe it. 5. The failure of the instrument display (if the water level and time of the meter and the water function are normal, it is not this problem) or the temperature probe is faulty. 6. Test the temperature of the water first, if the temperature is very high, it is the fault of the sensing device, if it is still at room temperature, it is the fault of electric heating or the failure of the leakage protector, which needs to be repaired by a special person.
