In this comprehensive guide, we will explore common Worcester Bosch boiler fault codes and their possible causes.
Common Worcester Bosch Boiler Fault Codes
Here are some of the most frequently encountered Worcester Bosch boiler fault codes, along with a brief description of the potential issues they may indicate:
- EA: This fault code indicates a problem with the boiler’s ignition, which may be caused by a lack of gas supply, a blocked flue, or a faulty ignition electrode.
- E2: This code suggests an issue with the boiler’s flow thermistor, which monitors the temperature of the water leaving the boiler. It may signal a loose connection or a faulty thermistor.
- E9: This code indicates a problem with the boiler’s safety temperature limiter, suggesting that the boiler has overheated. It could be due to insufficient water circulation, a blocked heat exchanger, or a faulty pump.
- E110: This fault code suggests that the boiler’s primary flow temperature has exceeded the maximum limit. Possible causes include a lack of circulation in the system, air trapped in the heat exchanger, or a faulty temperature sensor.
- E118: This code indicates that the boiler’s water pressure is too low, which may be caused by a leak in the system, inadequate water pressure, or a malfunctioning pressure sensor.
- E133: This fault code signifies a problem with the boiler’s gas supply. It could be due to a lack of gas, a blocked gas valve, or a faulty gas pressure sensor.
Addressing Worcester Bosch Boiler Fault Codes
If your Worcester Bosch boiler displays a fault code, it is essential to take the following steps:
- Consult the user manual: Your boiler’s user manual will contain detailed information about the fault codes and possible causes. Always refer to the manual for guidance on resolving specific issues.
- Check for common issues: Inspect the boiler and its surroundings for any visible problems, such as a blocked flue, a leak, or a disconnected gas supply.
- Reset the boiler: Some fault codes may be resolved by resetting the boiler. Follow the instructions in your user manual to perform a reset and clear the fault code.
- Call a professional: If the fault code persists or you are unsure how to resolve the issue, it is crucial to contact a qualified engineer for assistance. Attempting to fix the problem yourself could result in further damage or unsafe operation of the boiler.
