3. Red light fault solutions
1.Water pressure abnormality handling: When the water pressure gauge shows less than 1bar, water needs to be filled through the water replenishing valve to 1-1.5bar; if it exceeds 3bar, water needs to be drained through the radiator exhaust valve.
2.Ignition troubleshooting: Check whether the gas valve is open and confirm that the balance of the gas meter is sufficient. If it still doesn't work, contact a professional to check the ignition electrode.
3.Overheating protection treatment: Turn off the power and wait for 30 minutes before restarting, check whether the water pump is operating normally, and clean the impurities in the filter.
4. Preventive maintenance suggestions
• Check water pressure indicator monthly
• Clean burner dust quarterly
• Annual professional maintenance before heating season
• Install carbon monoxide alarms
5. User FAQs
Q: Can I continue to use it when the red light is on?
A: Absolutely prohibited! When the red light is on, it indicates that there is a security risk in the system, and it should be deactivated immediately and the cause investigated.
Q: What should I do if the red light is still on after resetting itself?
A: If the reset fails for 3 consecutive times, you must contact after-sales service. Forcible use may cause permanent damage to the device.
Q: Are there any differences between different brands of red light alarms?
A: The logic of the indicator lights of each brand is different. It is recommended to consult the manual. For example, the Bosch red light flashing three times indicates a gas valve failure, and the Vaillant red light staying on indicates insufficient water pressure.
From the above analysis, it can be seen that the red light alarm of the wall-mounted boiler involves many possibilities, and users should take corresponding measures according to the specific performance. The popularity of related topics has continued to rise recently, which also reflects the importance of maintenance of heating equipment in winter. It is recommended that users keep the contact information of local maintenance points and seek professional help in time when encountering complex faults.
