3. Step-by-step troubleshooting guide
When encountering a situation where the wall-mounted boiler does not produce water, it is recommended to follow the following steps to troubleshoot:
1.Check water pressure: First check the water pressure gauge of the wall-mounted boiler. The normal water pressure should be between 1-2bar. If it is lower than 1bar, water needs to be replenished through the water replenishment valve.
2.Check power supply: Make sure the wall-mounted boiler is powered on, especially if the power supply to the water pump is normal.
3.Check gas supply: Confirm that the gas valve is open, the gas meter has sufficient balance, and there is no leakage in the gas pipeline.
4.Check temperature settings: Make sure the temperature set value is higher than the current water temperature. Especially in winter, the set temperature may need to be raised.
5.Check anti-freeze protection: In extremely cold weather, the wall-mounted boiler may stop working due to anti-freeze protection, and you need to follow the instructions to release the protection.
4. Professional maintenance suggestions
If the problem still cannot be solved after the above troubleshooting, it is recommended to contact professional maintenance personnel. According to recent maintenance data, common situations requiring professional maintenance include:
| Maintenance items | Proportion | average repair cost |
|---|---|---|
| water pump replacement | 35% | 300-500 yuan |
| Pipe cleaning | 25% | 200-300 yuan |
| Circuit maintenance | 20% | 150-250 yuan |
| Others | 20% | It depends on the specific situation |
5. Preventive measures
In order to prevent the wall-mounted boiler from not producing water, it is recommended to take the following preventive measures:
1. Check the water pressure regularly to maintain appropriate water pressure levels.
2. Perform professional maintenance every year before the heating season, including cleaning pipes and inspecting key components.
3. Install a water filter to prevent impurities from clogging the pipes.
4. When the wall-mounted boiler is not used for a long time, drain the water in the pipes.
5. Pay attention to the service life of the wall-mounted boiler. It is recommended to consider replacing equipment that is more than 8 years old.
Through the above analysis and suggestions, we hope to help you solve the problem of no water coming out of the wall-mounted boiler. If the problem persists, be sure to contact professional maintenance personnel to ensure safety and normal use of the equipment.
