Potterton E40 Fault

The Potterton E40 error code indicates a fault with the central heating (CH) return thermistor. This sensor measures the temperature of the water returning to the boiler from the central heating system. A fault in the return thermistor can lead to inaccuracies in the boiler’s ability to regulate heating effectively, potentially causing the system to overheat or not heat adequately. Causes of Potterton E40 Error CodeFaulty Return Thermistor: If the thermistor is malfunctioning or damaged, it may provide incorrect temperature [...]

Potterton E20 Fault

The Potterton E20 error code typically indicates a central heating thermistor sensor fault. This sensor measures the temperature of the water in the central heating system, and a fault means the boiler’s control system is having difficulty accurately gauging this temperature. Incorrect readings from the thermistor can affect the boiler’s ability to efficiently regulate heating, leading to issues with maintaining the desired temperature in your home. Causes of Potterton E20 Error CodeFaulty Thermistor: If the thermistor is damaged or malfunctioning, [...]

Potterton E160 Fault

The Potterton E160 error code indicates a fan fault within the boiler system. The fan is an essential component that ensures safe operation by venting harmful combustion gases outside the property and drawing in air for the combustion process. A fault with the fan can lead to operational issues, including safety risks due to improper venting of exhaust gases. Causes of Potterton E160 Error CodeFaulty Fan: The fan itself may be malfunctioning due to wear, damage, or electrical issues, preventing [...]

Potterton E133 Fault

The Potterton E133 error code signifies a problem with the boiler’s ignition or gas supply. This fault occurs when the boiler attempts to ignite but fails, possibly due to no gas being available or the ignition process being disrupted. It’s a critical issue because it directly affects the boiler’s ability to provide heating and hot water. Causes of Potterton E133 Error CodeGas Supply Issues: Interruptions in the gas supply, such as the main gas valve being turned off or low [...]

Potterton E125 Fault

The Potterton E125 error code indicates a circulation fault within the boiler system. This fault is triggered when there’s an issue with the flow of water through the boiler, suggesting that the hot water is not being effectively circulated through the system. This can lead to inefficient heating and, in some cases, may prevent the boiler from operating. Causes of Potterton E125 Error CodeFaulty Pump: The circulation pump may be malfunctioning or seized, preventing the proper flow of water through [...]

Potterton E119 Fault

The Potterton E119 error code signifies a situation where the boiler is experiencing low water pressure. This condition occurs when the pressure in the central heating system falls below the minimum threshold required for the boiler to operate safely and efficiently. Low water pressure can affect the performance of your heating system, leading to inadequate heating or, in some cases, preventing the boiler from working entirely. Causes of Potterton E119 Error CodeLeaks in the Heating System: Small leaks within the [...]
