E133 Error Code Baxi Boilers

Boilers are machines. Even the most reliable and well-maintained boilers can encounter issues from time to time.
Let's find out what the E133 error code is in the Baxi boiler.
🔍 What is the E133 error code?
[E133 IGNITION BLOCK]
If your boiler shows E133, it means the ignition is blocked. This can occur due to insufficient gas or issues with the ignition process.
🛠️ Possible Causes:
Let's see what causes the E133 error
[GAS SUPPLY ISSUE]
The leading cause of the E133 boiler fault is the gas supply. When the boiler isn't getting any gas, it can cause a lockout. You can check this without opening the boiler."
[FAULTY GAS VALVE]
Another reason could be a problem with the gas valve. If the valve that lets gas into your boiler is closed or not working properly, the gas might not get to the burner.
[FROZEN OR BLOCKED CONDENSATE PIPE]
In freezing weather, the pipe that lets out condensation might freeze or get blocked. This frozen pipe outside can make the boiler stop working.
[FAULTY BOILER COMPONENTS]
The next reason could be a broken or faulty component in the boiler. If there's a faulty component, it should be replaced. Gas supply issues are often linked to defective boiler parts.
[FAULTY PCB (PRINTED CIRCUIT BOARD)]
A broken printed circuit board can also lead to the E133 boiler fault. If there's no continuous connection in the cable between the control panel and the burner, it might be a problem.
🔧 How to Troubleshoot:
Let's see how to fix the E133 error code.
[CHECK THE GAS SUPPLY]
First, check the gas supply. Make sure that all gas appliances in your home, including the boiler, are working correctly. If they are not, contact your gas supplier to check for any issues with the gas supply.
[CALL A GAS ENGINEER]
It's best to call a professional gas engineer. Although you might fix some issues on your own, always seek professional help to avoid causing bigger problems.
[CHECK THE BOILER IGNITION]
If your boiler won't start, check if the ignition is working. Make sure the gas inlet tap is open. Sometimes, it can get stuck, especially if the boiler hasn't been used for a while. Also, check if the gas inlet tap is jammed or damaged; if so, it must be replaced.
