Boilers are the unsung heroes of UK households, providing warmth and hot water when we need it most. However, these trusty appliances aren’t immune to issues. When your boiler encounters a problem, it often communicates it through error codes, which serve as a diagnostic tool. Understanding these error codes can help you troubleshoot issues efficiently or communicate them to a professional technician. In this comprehensive guide, we’ll explore some of the most common boiler error codes and their underlying causes, allowing you to tackle these challenges head-on.
Error Code E119 (Baxi Boiler):
Error code E119 is a common issue that many homeowners face. It often indicates a problem with the boiler’s pressure or circulation.
Causes:
a. Low Water Pressure: This is a frequent cause of E119 errors. Low water pressure can prevent your boiler from operating correctly, affecting both heating and hot water.
b. Circulation Pump Problems: If the circulation pump is faulty or blocked, it can hinder the flow of hot water through your heating system, triggering this error.
Solution:
To address an E119 error, first, check the water pressure gauge on your boiler. If it’s below the recommended level, you can try to repressurise the system following the manufacturer’s instructions. If the issue persists, or if you suspect problems with the circulation pump, it’s best to contact a professional heating engineer.
Error Code F28 (Vaillant Boiler):
Error code F28 is often associated with ignition or gas supply issues, and it can disrupt your boiler’s normal operation.
Causes:
a. Gas Supply Problems: A problem with the gas supply, such as a closed valve or a gas meter issue, can lead to F28 errors.
b. Ignition Issues: If your boiler fails to ignite correctly due to a faulty electrode or a blocked burner, it may trigger this error code.
Solution:
When faced with an F28 error, start by ensuring that your gas supply is on and the boiler’s pilot light is lit (if applicable). If the problem persists, it’s advisable to contact a Gas Safe registered engineer who can diagnose and repair the issue safely.
I’ve used Scott a couple of times and always found him to be knowledgeable and helpful. He is also very reliable and comes when he says he will come and is transparent about costs. I have no problem in recommending the Waterways.

Error Code L6 (Ideal Boiler):
Error code L6 often relates to an issue with your boiler’s temperature sensors, which are crucial for maintaining safe and efficient operation.
Causes:
a. Faulty Temperature Sensor: A malfunctioning temperature sensor can provide incorrect readings, causing the boiler to shut down to prevent overheating.
b. Wiring Problems: Damaged or loose wiring connected to the temperature sensor can also trigger L6 errors.
Solution:
To resolve an L6 error, it’s essential to consult a professional heating engineer. They will inspect the temperature sensor and associated wiring, repairing or replacing any faulty components to ensure your boiler operates reliably.
Error Code C6 (Worcester):
Error code C6 is typically linked to issues with your boiler’s fan or air supply.
Causes:
a. Faulty Fan: If the boiler’s fan is malfunctioning or blocked, it can lead to inadequate airflow, causing the C6 error.
b. Blocked Air Intake: The air intake pipe could be obstructed, preventing the boiler from receiving the necessary oxygen for combustion.
Solution:
When dealing with a C6 error, check if the boiler’s fan is working correctly and the air intake is clear of obstructions. If you’re unsure or suspect a faulty fan, it’s advisable to consult a professional technician for a thorough inspection and repair.
Error Code A10 (Vokera Boiler):
Error code A10 typically points to issues with your boiler’s ignition or flame detection system.
Causes:
a. Ignition Problems: Faulty ignition components, such as the spark electrode or ignition module, can lead to ignition failures and trigger the A10 error.
b. Flame Detection Issues: The boiler’s flame sensor may become dirty or malfunction, causing it to fail in detecting the burner flame.
Solution:
To resolve an A10 error, start by inspecting and cleaning the spark electrode and flame sensor. If the issue persists, it’s wise to contact a professional technician who can assess the ignition system’s condition and make any necessary repairs or replacements.
We have used Michael at Waterguys recently for a boiler service followed by an expected replacement. The team were great. They know their stuff and give advice but no hard sell. They are responsive, polite and left the place spotless. Would highly recommend.
