What is Error 133?
Error 133 is a flame detection fault common in several boiler brands, typically indicating an issue with gas supply or ignition. It’s the boiler’s way of saying, “I can’t start up safely.
Possible Causes of Error 133:
- No Gas Supply: Check if other gas appliances (like a stove) are working. If they aren’t, there might be an issue with your gas supply.
- Gas Valve Fault: This can prevent gas from reaching the boiler’s ignition point.
- Ignition Electrode or Sensor Issue: Sometimes, the ignition or flame detection sensors are dirty or malfunctioning.
DIY Steps Before Calling an Engineer:
- Reset the Boiler: Turn the boiler off, wait 5 seconds, then turn it back on. Sometimes, a reset is all it needs!
- Check the Gas Meter: If you have a prepayment meter, ensure there’s enough credit.
- Inspect for Gas Shutoff: In case of recent work or suspected leaks, the gas supply may have been turned off.
- Ventilation Check: Make sure the area around the boiler is well-ventilated and free from blockages.
