How to debug Bosch wall-hung boiler
Bosch wall-hung boiler is an important equipment for home heating, and its debugging process directly affects the use effect and safety. The following is a compilation of hot topics and hot content about Bosch wall-hung boiler debugging in the past 10 days across the Internet, combined with structured data to provide you with a detailed guide.
1. Preparations before debugging
Before debugging the Bosch wall-hung boiler, make sure that the following conditions are met:
| Project | request |
|---|---|
| Power connection | 220V stable voltage, good grounding |
| Waterway system | Filled with water and the pressure is between 1-2Bar |
| gas supply | There is no leakage in the pipeline and the valve is open |
| environmental inspection | The installation location is well ventilated and free of flammable materials |
2. Detailed explanation of debugging steps
The following is the standard commissioning process for Bosch wall-hung boilers:
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1. Power-on self-test | Press and hold the power button for 3 seconds to start the self-test program | Observe the fault code (such as E9 indicating insufficient water pressure) |
| 2. Pressure regulation | Adjust to 1.5Bar through the water replenishing valve | It is recommended to maintain 1.5-2Bar in winter |
| 3. Gas adaptation | Select the corresponding mode according to the gas type | Natural gas/liquefied gas require different settings |
| 4. Temperature setting | The recommended heating water temperature is 55-65℃ | Floor heating system does not exceed 55℃ |
| 5. Trial run | Observe the flame status and outlet water temperature | Normal flame should be blue without black smoke |
3. Solutions to common problems
Based on recent user feedback on high-frequency issues:
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| Frequent flameout | Insufficient gas pressure/blocked smoke pipe | Check gas meter/clean flue |
| Too much noise | There is air in the water pump/the installation is unstable | Exhaust treatment/reinforcement bracket |
| Heats up slowly | System scale buildup/low power settings | Clean pipes/adjust power level |
| Show E1 error | Ignition failure | Check electrode spacing (3-5mm) |
4. Maintenance suggestions
Things to note when extending the life of your wall-hung boiler:
| cycle | Maintenance items | Operational points |
|---|---|---|
| monthly | pressure check | If it is lower than 0.8Bar, you need to replenish water immediately. |
| every year | Professional maintenance | Including heat exchanger cleaning, etc. |
| 3-5 years | Replacement accessories | Water pump/gas valve and other wearing parts |
5. Safety warning
1. It is strictly prohibited to disassemble the panel while the power is on.
2. If gas leakage occurs, close the main valve immediately
3. There is no need to drain the system water if it is not used for a long time in winter.
4. Non-professionals should not adjust the gas proportional valve.
Through the above structured debugging guide, users can systematically master the operating points of Bosch wall-hung boilers. It is recommended that professional technicians complete the initial commissioning after the first installation. Regular maintenance during daily use can ensure efficient and stable operation of the equipment.
