The modern arrangement of gas equipment facilitates operation. If one of the parts fails, you do not have to diagnose the entire system. The self-diagnosis of the Solly boiler will display errors before you know about the breakdown. The decoding of the characters will indicate where to look for the fault.
The device, the principle of operation of the boiler Solly
The brand is presented in three series:
- Solly Standart.
- Comfort.
- Primer.
The combustion chamber of the double-circuit boiler "Solly" can be open and closed. In the latter case, the fan has a front and rear bearing, which ensures a long service life of the equipment. Some models are equipped with a bithermic heat exchanger. The design difference in the structure is “tube in tube”. One of them circulates water for the heating system, the other - for hot water in taps.
The steel burner is not susceptible to corrosion, and the circulation pump is regulated in three positions. The control board of the gas boiler is enclosed in a plastic box. It protects it from moisture, heat. Button control device. The display shows temperature indicators, error codes.
Errors and malfunctions
Incorrect connection and operation, untimely maintenance lead to problems in the operation of the equipment.Seldom - factory defect, low-quality spare parts. As a result, the boiler is blocked, and a code is displayed on the screen. The meaning can be found in the instructions and our table.
Display code | What does it mean | Trouble-shooting |
cs | Incoming thermostat problems. | Check the sensor and its contacts. Tighten the connections to the control board, install a new loop or thermostat if damaged. Diagnostics required:
Problems with the control module require a wizard call. |
Dh error | Ignition problems. | What to do:
In the event of a system interruption, wait until the feed is restored. |
dy | Voltage drops in the network. Abnormality> 187 V, <275 V. | Connect a stabilizer to normalize the voltage. |
yl | The pressure in the system drops. |
|
Fy error | Problems with the fan. The blades do not rotate. |
|
Gs error | Radiator overheated, difficulties in the operation of the pressure switch. | Verify that the temperature sensor and pump wiring are correct. If broken, replace the pump. Clean the filters from dirt. Descale the heat exchanger. Plaque interferes with the normal circulation of water, so the temperature rises. |
sy | Failure in the hot water temperature sensor. |
|
CO | Problems with the settings. |
|
hs | The temperature sensor on the return line failed. | Diagnose and replace. |
ls | The input line controller is defective. |
Perform breakdown prevention once a year. Clean the radiator and other parts from scale and dirt, monitor the condition of the chimney and the presence of draft. Set the boiler according to the instructions. If you are not sure that you can fix the equipment yourself, it is better to contact a service center.
