What Is Baxi Error Code E133?
Baxi Error Code E133 is a common error that occurs in Baxi boilers. It indicates that there is an issue with the ignition, which means that the boiler is unable to light the gas to create heat. This error code usually appears on the boiler's digital display panel and is often accompanied by a flashing red light.
Causes Of Baxi Error Code E133
Baxi Error Code E133 indicates a problem with the ignition of the boiler. The most common causes of this error code include:
Lack of gas supply: If the gas supply to the boiler is interrupted or blocked, the boiler may not be able to ignite properly.
Low gas pressure: If the gas pressure is too low, the boiler may not ignite properly. This could be due to a problem with the gas supply or a fault with the gas valve.
Faulty ignition leads or electrodes: If the ignition leads or electrodes are worn or damaged, the boiler may not ignite properly.
Blocked condensate pipe: If the condensate pipe is blocked, it can cause a backup of water in the boiler, which can affect the ignition.
Air in the gas supply: If there is air in the gas supply, it can prevent the boiler from igniting properly.
Faulty PCB: A fault with the printed circuit board (PCB) can cause the boiler to fail to ignite.
Other electrical faults: Various other electrical faults, such as faulty wiring or a faulty sensor, can cause the boiler to fail to ignite.
It is recommended that you consult a qualified heating engineer or plumber to diagnose the cause of the error code and carry out any necessary repairs.
How To Fix Baxi Error Code E133?
Baxi Error Code E133 is an indication of a failure to ignite. Here are some steps you can take to fix the error:

Check for a gas supply: Make sure that your gas supply is turned on and that there is gas available. Check other gas appliances in your home to see if they are working properly.
-
Reset the boiler: Turn off the boiler and wait for 10-15 minutes. Turn it back on and see if the error has cleared.
-
Check the pressure: Ensure that the boiler pressure is between 1 and 1.5 bar. If it is too low, use the filling loop to increase the pressure.
-
Check the condensate pipe: Ensure that the condensate pipe is not frozen or blocked. If it is, thaw the pipe or clear the blockage.
-
Check the ignition system: The problem could be with the ignition system. Check the spark electrode and the wiring to ensure that they are in good condition.
-
