Understanding the E133 Error

The E133 error is a common fault code that appears on many boiler models, indicating a fault with the ignition or flame detection. This error usually occurs due to problems with gas supply, ignition electrodes, or the flame sensor. When your boiler displays the E133 error, it means the system has detected a flame failure during operation, and as a safety measure, the boiler shuts down to prevent any potential hazards.

Troubleshooting the E133 Error

Check the Gas Supply

A disrupted gas supply is one of the most common causes of the E133 error. Begin by ensuring that the gas supply to your property is not interrupted. Check other gas appliances, such as your stove or gas metre, to verify if they are working correctly. If there is no gas supply, contact your gas provider immediately.

 

Reset Your Boiler

Sometimes, a simple reset can resolve the E133 error. Locate the reset button on your boiler control panel, usually marked with a flame symbol or a reset label. Press and hold the reset button for a few seconds, allowing the boiler to reset itself. If the error persists after the reset, move on to the next steps.

 

Inspect the Flame Ignition Electrodes

The ignition electrodes are responsible for sparking the gas supply and igniting the boiler’s burner. Over time, they can become dirty or worn out, leading to a weak or intermittent flame. Carefully remove the front cover of your boiler and locate the ignition electrodes. Clean them gently using a soft brush or cloth, ensuring there is no dirt or residue. If the electrodes are damaged or heavily worn, it’s best to consult a professional heating engineer to replace them.

 

Check the Flame Sensor

The flame sensor is another critical component that detects the presence of a flame within the boiler. If it becomes dirty or faulty, the sensor may not register the flame, triggering the E133 error. Refer to your boiler’s user manual to locate the flame sensor. Clean it carefully using a soft cloth, ensuring there is no dust or debris affecting its operation. If the problem persists, consider contacting a heating engineer to inspect and potentially replace the flame sensor.

 

Seek Professional Assistance

If you’ve followed the above steps and the E133 error still persists, it’s time to seek professional help. Contact Tyne & Wear Heating or a qualified heating engineer who can diagnose the issue accurately and carry out any necessary repairs. They have the expertise to handle complex boiler problems, ensuring your boiler is safe and back to its optimal performance.

 

Preventing Future E133 Errors

Prevention is always better than cure when it comes to boiler issues. Here are a few tips to help you avoid future E133 errors:

  • Schedule Regular Boiler Servicing: Arrange annual servicing for your boiler with a qualified engineer to ensure it operates efficiently and detect any potential problems before they become major issues.
  • Keep Your Boiler Area Clear: Avoid cluttering the space around your boiler to ensure proper airflow and ventilation. Remove any debris, flammable materials, or obstructions that may hinder its operation.
  • Follow Manufacturer’s Guidelines: Always refer to the manufacturer’s instructions for your specific boiler model. Adhering to their guidelines for maintenance and operation can significantly reduce the risk of errors.
