How to deal with wall-hung boiler failures
With the advent of winter, wall-mounted boilers are important equipment for home heating, and their operating status is directly related to the comfort of the home. However, wall-hung boilers will inevitably experience some failures during use. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed introduction to common wall-mounted boiler failures and treatment methods to help you solve the problem quickly.
1. Common faults and solutions of wall-hung boilers

| Fault phenomenon | Possible reasons | Treatment method |
|---|---|---|
| Wall mounted boiler cannot start | Power failure, insufficient gas supply, low water pressure | Check the power connection, confirm that the gas valve is open, and adjust the water pressure to 1-1.5bar |
| Wall-hung boiler is noisy when operating | The fan accumulates dust, the water pump air is not exhausted, and the burner accumulates carbon. | Clean the fan, drain the water pump, and clean the burner |
| Wall-hung boiler frequently flames out | The gas pressure is unstable, the heat exchanger is blocked, and the temperature sensor is faulty. | Check gas pressure, clean heat exchanger, replace temperature sensor |
| Wall-hung boiler leaking | Aging sealing rings, loose pipe connections, and excessive pressure | Replace sealing rings, tighten pipe connections, and reduce water pressure |
| Wall-mounted boiler heating effect is poor | The radiator is clogged, there is air in the system, and the temperature setting is too low. | Clean radiators, drain system air, and adjust temperature settings |
2. Daily maintenance suggestions for wall-hung boilers
In order to reduce the occurrence of wall-hung boiler failures and extend its service life, routine maintenance is essential. Here are some maintenance suggestions:
1.Check water pressure regularly: The water pressure of the wall-hung boiler should be maintained between 1-1.5bar. Too low or too high will affect normal operation.
2.Clean filter: Clean the water inlet filter regularly to prevent impurities from clogging the pipes.
3.Check gas pipes: Make sure there is no leakage in the gas pipeline and the gas valve is opened normally.
4.Regular maintenance: It is recommended to ask professionals to perform comprehensive maintenance on the wall-mounted boiler every year, including cleaning the heat exchanger, checking the fan, etc.
3. Precautions for wall-hung boiler troubleshooting
1.Safety first: When dealing with a wall-mounted boiler failure, be sure to cut off the power and gas supply first to ensure safety.
2.Avoid disassembling yourself: For complex faults, such as circuit board problems or gas system failures, it is recommended to contact professional maintenance personnel.
3.Keep warranty certificate: If the wall-mounted boiler is still within the warranty period, contact the manufacturer or authorized service provider for repairs to avoid voiding the warranty due to self-handling.
4. Answers to popular wall-hung boiler faults
According to the hot topics on the Internet in the past 10 days, the following are some frequently asked questions and answers by users:
| question | Answer |
|---|---|
| What should I do if the wall-hung boiler displays the E1 fault code? | E1 usually indicates ignition failure, check whether the gas supply and ignition electrode are normal. |
| Is the water temperature unstable when the wall-mounted boiler is heating? | There may be air in the system, try to bleed it or check if the water pump is working properly. |
| Does your wall-hung boiler make a "buzzing" sound when running? | It may be that the fan is dusty or the water pump bearing is worn, and the parts need to be cleaned or replaced. |
| How to maintain the wall-hung boiler if it is not used for a long time in winter? | Drain the system water and turn off the power and gas valves to prevent freezing and cracking. |
5. Summary
Although wall-mounted boiler failures are common, most problems can be solved through simple troubleshooting and treatment. Mastering basic troubleshooting methods can not only save repair costs, but also ensure the continuity of home heating. If you encounter a fault that cannot be solved, be sure to contact professionals in time to avoid greater losses caused by improper operation.
