How to fix Baxi boiler error code 133?

Baxi boilers are known for their reliability and efficiency, but like any home appliance, they can sometimes run into issues. If your Baxi boiler is displaying error code 133, it means there’s an issue with the ignition or gas supply. 

In simpler terms, the boiler is struggling to light up and produce heat. This issue can disrupt your heating and hot water supply, but don’t worry—there are solutions.

Understanding what causes the error and following simple troubleshooting steps can often fix the issue without professional assistance.

Let’s explore how you can solve this problem

Step-by-Step Guide to Fix Error Code 133

Before you start, ensure your safety by switching off the boiler and consulting the user manual. Here are some steps you can follow to fix the issue:

  1. Reset the Boiler
    Locate the reset button on your boiler, usually marked with an arrow or a reset symbol. Press and hold it for a few seconds until the boiler restarts. This can sometimes resolve minor glitches.

  2. Check the Gas Supply
    Ensure that your gas meter is switched on and that you have an active gas supply. If you suspect a gas outage, contact your gas provider for assistance. If the gas pressure seems low, you may need a professional to adjust it.

  3. Inspect the Condensate Pipe
    In cold weather, the condensate pipe, which removes excess water from the boiler, may freeze. Locate the pipe, usually running outside your home, and check for blockages. If frozen, thaw it using warm (not boiling) water or wrap it with a warm cloth.

  4. Inspect for Airlocks in the Gas Line
    Air trapped in the gas line can also cause ignition issues. If you suspect this, it’s best to call a registered engineer to bleed the gas line safely.
