The return thermistor is responsible for measuring the temperature of the water that returns to the boiler after circulating through the heating system. If the return thermistor is not functioning properly, it can cause the boiler to malfunction and display the F5 error code.
To diagnose an F5 error, the first step is to check the fault and error symbols on the boiler’s display panel. The F5 error code is commonly associated with error code 101, which indicates a problem with the return thermistor. Error code 104 indicates a problem with the flow thermistor, which measures the temperature of the water flowing into the boiler.
Common Causes of F5 Faults
There are several common causes of F5 faults in a boiler system. One of the most common causes is a faulty return thermistor. If the return thermistor is not functioning properly, it may provide abnormal temperature readings, which can cause the boiler to malfunction and display the F5 error code.
Other potential causes of F5 faults include problems with the boiler’s wiring, control board, or power supply. In some cases, the F5 error code may be caused by a problem with the flow thermistor, which measures the temperature of the water flowing into the boiler.
Detecting abnormal temperature readings is crucial when it comes to identifying F5 faults. If the return thermistor is not providing accurate temperature readings, it may need to be replaced. It is important to note that attempting to fix an F5 fault without the necessary expertise may result in further damage to the boiler system. In such cases, it is recommended to contact a Gas Safe engineer or the manufacturer for assistance.
In conclusion, the Ideal F5 Fault Code is a common error code associated with a problem with the return thermistor in a boiler system. Diagnosing an F5 error involves checking the fault and error symbols on the boiler’s display panel and detecting abnormal temperature readings. Common causes of F5 faults include a faulty return thermistor, wiring problems, control board issues, or a faulty flow thermistor. It is important to seek professional assistance when attempting to fix an F5 fault to prevent further damage to the boiler system.
Troubleshooting and Resolving F5 Faults
Resetting the Boiler
If your Ideal boiler is showing the F5 fault code, the first step is to try resetting the boiler. This can be done by following the instructions in the boiler manual. Typically, this involves turning off the power supply to the boiler, waiting for a few minutes, and then turning it back on.

Understanding Boiler Systems and Components
The Role of Thermistors in Boiler Systems
Thermistors are critical components in boiler systems. They are temperature sensors that measure the temperature of the water in the boiler, and provide feedback to the boiler’s control system. Specifically, the flow thermistor measures the temperature of the water as it enters the boiler, while the return thermistor measures the temperature of the water as it leaves the boiler and returns to the heating system.
The information provided by these sensors is used by the boiler’s control system to regulate the firing rate of the boiler based on the outlet outflow. This ensures that the water leaving the boiler is at the correct temperature, and that the heating system is operating efficiently.
Common Boiler Components and Their Functions
In addition to thermistors, there are several other common components in boiler systems. These include:
Water pressure gauge: This gauge provides an indication of water pressure inside the boiler. If the pressure is too low, the boiler may not function properly, while high pressure can cause damage to the system.
Hot water demand sensor: This sensor detects when hot water is being used, and signals the boiler to heat water as needed.
Overheat thermostat: This safety device monitors the flow temperature of the water in the boiler. If the temperature exceeds a certain threshold, the overheat thermostat will shut off the boiler to prevent overheating inside your boiler.
Pump: The pump is responsible for circulating water throughout the heating system. It ensures that hot water is delivered to the radiators and other components of the heating system.
By understanding the role of these components in a boiler system, homeowners can better troubleshoot issues and maintain their heating systems. Regular maintenance, including checking and replacing faulty thermistors, can help ensure the efficient and safe operation of the boiler.
