What is the Baxi E50 Error Code?
If you see an E50 error on your Baxi boiler, it means there’s likely a temperature sensor error in your hot water system. This happens when the maximum flow temperature is exceeded, causing safety devices such as the thermostat sensor or PCB (Printed Circuit Board) to shut the system down.
Common Causes of the Baxi E50 Fault Code
Several internal and external issues can trigger the E50 error:
- Faulty Temperature Sensor: Incorrect readings due to sensor malfunction.
- Blocked Flue: Poor ventilation causing unstable temperature control.
- Jammed Pump: Hindered water circulation leading to overheating.
- Gas Supply Issues: Irregular gas supply can disrupt normal boiler function.
- Air Pressure Switch Failure: Incorrect sensing of boiler conditions.
- External Device Failure: Components like heat pumps failing to function properly.
How to Fix the Baxi E50 Error Code
Time needed: 5 minutes
You can try these steps to resolve the issue:
- Reset the Boiler
Press the reset button to clear temporary faults.
- Replace Faulty Sensors
Check and replace the thermistor or hot water temperature sensor.
- Clear Blockages
Inspect and unblock the flue terminal for proper ventilation.
- Check the Pump
Ensure the pump isn’t jammed; professional help may be needed.
- Perform Calibration
Run a calibration check to ensure component accuracy.
- Call a Gas Safe Engineer
If the error persists, a Gas Safe registered engineer should inspect the system.
When to Call a Gas Safe Engineer
If resetting and checking basic components doesn’t solve the issue, you may be dealing with:
- Internal leaks
- Pressure sensor failure
- Faulty expansion vessel or pressure relief valve
A qualified Gas Safe engineer can safely identify and repair these complex issues, ensuring your boiler runs efficiently and safely.
Preventing Future Baxi E50 Faults
To reduce the risk of future E50 errors, follow these preventative tips:
- Schedule Regular Maintenance with a Gas Safe engineer.
- Monitor Water Pressure to avoid poor circulation.
- Inspect Flues and Vents for blockages.
- Check Temperature Sensors regularly.
- Use Correct Settings to avoid overheating.
Conclusion
The E50 error code on a Baxi boiler is a strong signal of a temperature sensor issue or overheating problem. While minor fixes can be done at home, involving a Gas Safe registered engineer ensures the fault is diagnosed and resolved safely. Regular check-ups and proper maintenance are key to keeping your Baxi boiler reliable, efficient, and ready to deliver consistent hot water and heating.
Frequently Asked Questions
E50 – The possible cause could be a “Hot water NTC (Negative Temperature Coefficient) error”. This indicates a problem with the NTC sensor responsible for measuring the temperature of the hot water in your heating or hot water system. Regular boiler servicing will help deter issues like this.
Error E50 typically occurs when an empty bouquet of channels is selected on your DStv decoder. This means the decoder is trying to access a channel list that has no active channels or subscriptions assigned to it. This issue is often easy to resolve by selecting the correct bouquet or resetting your decoder settings.
An E1 error generally means that your boiler pressure is too low, sometimes causing your boiler to lockout or stop working. This can be fixed by simply topping up the boiler pressure to between 1 and 2 bars.
