When the package makes a lot of noise and the red light in it lights up and steam rises from the package and finally turns off, it is said that the package has boiled. This problem may worry users and cannot be solved by these people.
There are various reasons for the package to boil, among them, the circulation pump is broken, the return and return valves are closed, the motor valve is burnt, the return filter net is dirty, the secondary converter and the main converter are damaged. Bypass of the device, closed upper and lower valves of the radiators, damaged control board, etc. In the following, these reasons and how to fix them have been explained.
But before we go into the reasons for the wall packages to boil, we must remind that the packages both in winter and in Boiling occurs in summer and this is more common in winter.
But single-converter packages boil more in winter because this type of package uses a pump in winter and it is possible. The pump is jammed, but in the summer, the package pumps are turned off and there is no need to turn them on.
The reasons for welding the package
Disturbance in the flow of water in the package circuit
Sometimes, for various reasons such as the formation of sediment, the water flow path is blocked and the water cannot circulate in the circuit. . In addition, the expansion source of the device may be damaged or have a leak, which can interfere with the flow of water.
Aeration of the package is one of the things that should be done in the periodical services of the package, and if it is not done, the performance of the package may be disturbed and various problems may arise in it. One of the problems that occurs if the package is not ventilated is the package boiling. Lack of ventilation causes the pump to circulate air instead of circulating water. The presence of air in the package can increase the pressure of the package and eventually lead to boiling of the device. Of course, there is no possibility of water movement in the path of the package and it can lead to boiling of the package. To solve this problem, it is necessary to descale the package converter by acid washing method. This work requires high skill and beginners are not able to do it and may cause many risks for themselves and the package. There is a problem in the circulation pump of the package. The circulator pump is responsible for moving the water in the heating circuit of the package and for this purpose it sucks the water from the radiator and directs it to the primary converter. After the water is heated by the burner in the primary exchanger, it is transferred to the radiator or the secondary exchanger and loses its heat and finally enters the pump.
This cycle is constantly repeated. And thus the water flows in the circuit. Now, for any reason, the circulator pump may have a problem and break down. Sometimes, a pump may burn, and in both cases, it will cause the water not to flow in the circuit and eventually boil the package. In such cases, it is necessary for the repairer of the package to diagnose the device and if the problem is with the pump, repair or replace it.
Defective engine valve
As mentioned above, the engine valve is one of the main parts of the package and if this part has a problem for any reason and If it gets damaged, it can cause the package to boil and the device to turn off. To solve this problem, it is necessary to open the valve and check its springs, which should be done by a professional package repairer.
Low gas pressure
Just as high pressure in the package can cause the device to boil, the opposite is also true and low pressure can also cause the wall package to boil and shut down. The low pressure of the gas causes that there is no flame and heat in the package and the result is the boiling of the device.
