Common Boiler Error Messages and How to Fix Them

‍

1. Error Code E119 (Baxi Boiler)

‍

‍

What it means: Error E119 typically points to low water pressure or a problem with the boiler’s circulation system.

Causes:

• Low Water Pressure: Your boiler needs a certain amount of pressure to operate effectively. If the pressure drops, it can cause the system to malfunction.
• Circulation Pump Issues: A blocked or faulty circulation pump can restrict hot water flow, triggering the error.

Solution:
Start by checking the pressure gauge on your boiler. If it's below 1.0 bar, follow the manufacturer’s instructions to repressurize the system. If this doesn't fix the issue, you might have a problem with the circulation pump, which requires professional attention. For fast, reliable service, reach out to Minuteman Water Heaters for boiler repair in the Boston and Cambridge area. Schedule a service.

2. Error Code F28 (Vaillant Boiler)

‍

‍

What it means: This error often signals ignition or gas supply problems.

Causes:

• Gas Supply Issues: A blocked gas valve or a disruption in gas flow can cause this error.
• Ignition Failure: If the boiler’s ignition system is faulty, it will struggle to light the burner.

Solution:
Ensure your gas supply is functioning and that no valves are closed. If the problem persists, or if you suspect an issue with the ignition system, it’s time to call a Gas Safe registered engineer.

3. Error Code L6 (Ideal Boiler)

‍

‍

What it means: This code indicates an issue with your boiler's temperature sensor.

Causes:

• Faulty Temperature Sensor: A malfunctioning sensor could send incorrect temperature readings, causing your boiler to shut down to prevent overheating.
• Wiring Problems: Damaged or loose wiring connected to the sensor can also trigger the error.

Solution:
This issue requires the expertise of a qualified heating engineer. They’ll inspect the temperature sensor and repair or replace any faulty components. Minuteman Water Heaters can help get your system back up and running. Contact our team for immediate assistance.

4. Error Code C6 (Worcester Boiler)

What it means: This error is usually related to fan or air supply issues.

Causes:

• Fan Malfunction: The boiler fan may not be working properly, which can prevent the correct airflow needed for combustion.
• Blocked Air Intake: If your boiler’s air intake is blocked, it won’t receive enough oxygen for safe operation.

Solution:
Check to see if the fan is running or if the air intake is clear of obstructions. If you’re not sure how to do this, or the fan seems faulty, call in a professional. Minuteman Water Heaters specializes in boiler repair and can help you quickly fix the issue. Book a repair service here.

5. Error Code A10 (Vokera Boiler)

‍

‍

What it means: This error indicates ignition or flame detection system issues.

Causes:

• Ignition Problems: Faulty spark electrodes or ignition modules can cause ignition failures.
• Flame Detection Issues: A dirty or faulty flame sensor may prevent your boiler from detecting the burner flame.

Solution:
You can try cleaning the spark electrode and flame sensor to see if it resolves the issue. If the error persists, it’s time to contact a professional. Minuteman Water Heaters offers thorough inspections and repairs for boilers in Cambridge and Boston. Get in touch for a fast solution.
