E133 error code boiler
If you’ve recently encountered the E133 error code on your boiler, you’re likely feeling frustrated, wondering what’s causing the issue and how to fix it. This common boiler error code, especially found in Baxi boilers, typically points to a problem with ignition or flame detection. In this blog post, we’ll explain what the E133 error code boiler means, its causes, and how to resolve it, so you can get your heating back on track.
What Does the E133 Error Code Mean?
The E133 boiler error code usually appears on Vaillant, Ideal, and Baxi boilers, signaling that there is an issue with the ignition or flame detection system. The boiler tries to ignite but fails to detect the flame once it has been lit, which means the heating and hot water will not work until the issue is resolved.
Common Causes of the E133 Error Code
Several issues could cause the E133 error code on your boiler and pinpointing the exact cause will help you fix the problem more efficiently. Here are the most common culprits:
No Flame Detected : Your boiler may attempt to ignite, but it fails to detect a flame. This can be caused by a faulty ignition electrode, a dirty flame sensor, or a blocked gas valve.
Gas Supply Issue: If there’s an interruption in the gas supply or the pressure is too low, the boiler won’t be able to ignite. Ensure that the gas is switched on, and the gas pressure is at the correct level.
Flame Sensor Malfunction: The flame sensor monitors the flame inside the boiler. If it’s dirty, damaged, or malfunctioning, it may fail to detect the flame, causing the E133 boiler error code.
Electrical Problems: A problem with the boiler’s wiring, especially the PCB (Printed Circuit Board), can cause communication failures between components, resulting in the E133 boiler error code.
How to Fix the E133 Error Code
f you’re dealing with the E133 boiler error code, there are a few steps you can take to try and resolve the issue before calling in a professional.
- Check The Gas Supply: Ensure that the gas supply to your boiler is turned on. Verify that there’s no interruption in service and that the pressure is at the correct level. If you suspect a gas issue, you may need to contact your gas supplier.
- Reset The Boiler: Try resetting the boiler according to the manufacturer’s instructions. This can sometimes clear minor faults and allow the system to restart.
- Inspect the Flame Sensor And Ignition Electrode: If the flame sensor or ignition electrode is dirty or damaged, it can fail to detect the flame. You can gently clean the components with a soft cloth or brush, but if they appear damaged, they may need to be replaced.
- Examine the Gas Valve: Check the gas valve for any blockages or malfunctions. If there’s a problem with the valve, the boiler may not receive the necessary gas supply to ignite.
- Check for Electrical Issues: Inspect the electrical connections for any loose or damaged wires. A faulty PCB can also cause communication issues between the components. If you’re unsure about the electrical components, it’s best to call a professional engineer.
When to Call a Professional
If you’ve tried the troubleshooting steps above and the E133 error code boiler persists, it’s time to call a qualified heating engineer. Some issues, such as faulty ignition electrodes, damaged flame sensors, or problems with the gas valve or PCB, require professional expertise to repair safely and correctly.
The E133 error code on a boiler is a common issue with boilers that can usually be traced to ignition or flame detection problems.
