Understanding Common Potterton Boiler Fault Codes

Potterton boiler fault codes are a system created to signify a particular issue with your boiler, designed to help you understand what might be going wrong. They act as indicators to identify potential malfunctions within the boiler system and allow for appropriate actions to be taken to rectify these issues.

The Potterton boiler range includes various models such as Potterton Promax, Potterton Suprima, and Potterton Performa, among several others. Like most other boilers, there's a built-in feature which conveys error codes that determine which specific part is causing the trouble. Each error code refers to a different kind of boiler fault.

Let's explore some of the common Potterton boiler fault codes and what they represent:

1. **E28/E29 – No ignition/ Flame detection fault:** This indicates that the boiler is not firing up to produce the necessary heat or flame detection has failed. Causes might include a problem with the ignition leads, electrode, or the gas supply.

2. **E50 – E110 – Overheat fault:** Various codes fall within this bracket, signifying overheating within the boiler. This might occur due to blockage in the pump, insufficient water in the system, or maybe an issue with the pump itself.

3. **E119 – Low-water pressure fault:** This indicates that the pressure has fallen below the minimum operational levels of 0.5 bar. Re-pressurising the boiler can usually resolve this.

4. **E160 – Fan Fault:** This implies a potential issue with the operation of the fan. The fan may be stuck or there may be an electrical fault causing this error.

5. **E168 – Loss of power or power supply fault:** This error appears when boiler power was interrupted or there's a problem with the control board.

Each of these errors may demand different solutions, ranging from a simple reset of the system to a complete replacement of parts. It is always recommended to contact a Gas Safe Registered Engineer to look at your boiler when any of these error codes appear. They can identify the root cause and carry out repair tasks safely and efficiently.

There are also some less common fault codes you may encounter. These include:

6. **E1 – Pump overrun:** Occurs when the pump does not switch off when it should. It might be due to a wiring fault or a circuit board issue.

7. **E2 – Blocking error:** Shown when there are blockages in the chimney or the flue.

8. **E20 – Boiler safety temperature sensor fault:** Indicates the boiler is operating above its normal temperature limit.



9. **E118 – System pressure low:** This error occurs when the system pressure is extremely low and requires urgent repressurisation.

10. **E133 – Gas supply error:** Appears in case of an interruption in the gas supply, or if the gas valve shut-off function has failed.

In understanding these codes, it’s important to remember that they do not directly provide a solution, but rather provide key information about the fault. It is always a smart and safe move to summon a professional in dealing with your boiler’s issues.

To prolong the life of your Potterton boiler and to ensure it operates efficiently, regular maintenance and annual servicing are important proactive steps. Apart from this periodic check, it is necessary to be alert for changes in boiler behavior and to respond promptly. With COVID-19 keeping us all at home more frequently, a successful boiler understanding may just make your quarantine period a bit more comfortable and worry-free.

However, under no circumstances should unqualified individuals attempt to repair or tamper with boiler components. Not only can this lead to further damage, but it can also create a significant safety risk. Always consult a Gas Safe registered engineer to handle any issues with your Potterton boiler.

It's important to note, some boiler problems may lay outside the scope of standard fault codes. Unusual noises, inconsistent heating, or increased energy bills may also suggest issues with your boiler. Regular checks and routine services are the best way to ensure your boiler stays in optimal working condition.

This comprehensive understanding of Potterton boiler fault codes can be an invaluable tool for home owners. By detecting faults early, one can prevent small problems from escalating into more significant faults, thereby saving money on substantial repairs or replacements in the long term. Remember, the data is for informative purposes only. Any attempt to repair should be carried out by a gas safe registered professional. With credible recognition of these codes, we can keep our homes warm, safe, and comfortable throughout the colder months and indeed, year-round.
