Alpha E10 Fault

The Alpha E10 error code indicates an overheat condition in the boiler. This situation arises when the boiler’s internal temperature exceeds the maximum safe limit, which can trigger safety mechanisms to shut down the boiler to prevent damage or a safety hazard. An overheat condition can be caused by several factors that disrupt normal boiler operation. Causes of Alpha E10 Error CodePump Failure: A malfunctioning or seized central heating pump can prevent water from circulating properly, causing heat to build [...]

Alpha common fault and error codes

Alpha boilers, like other brands, use fault and error codes to indicate specific problems within the system. These codes help in diagnosing issues, facilitating quicker repairs. Below are some common Alpha boiler fault and error codes and their typical meanings:E10: Overheat – This code indicates that the boiler has exceeded its safe operating temperature, potentially due to a blockage in the system or a failure in the pump or thermostat. E20: High-Pressure Fault – This error is shown when the [...]

Ariston 504 Fault

The Ariston error code 504 typically indicates a flame lift or flame detection fault during operation. This means the boiler’s control system has detected an unexpected extinguishing of the burner flame under normal operating conditions. Such a fault can pose safety concerns and affect the boiler’s efficiency and heating performance. Causes of Error Code 504Intermittent Gas Supply: Fluctuations in the gas supply can cause the flame to extinguish unexpectedly. Faulty Gas Valve: A malfunctioning gas valve may not provide a consistent [...]

Ariston 501 Fault

The Ariston error code 501 indicates a problem with flame detection. Specifically, this code is shown when the boiler’s control system attempts to ignite the burner, but no flame is detected, or the flame signal is lost shortly after ignition. This fault suggests issues with the ignition process or the components involved in detecting the flame. Causes of Error Code 501Gas Supply Issues: Inadequate gas pressure or interruptions in the gas supply can prevent the burner from igniting properly. Faulty Ignition [...]

Ariston 306 Fault

The Ariston error code 306 indicates a fault with an external probe, which is typically an external temperature sensor used to measure outdoor temperatures or the temperature in specific zones of a heating system. This sensor plays a crucial role in enabling the boiler to adjust its operation based on external conditions, enhancing efficiency and comfort. A fault with this probe can affect the boiler’s ability to modulate its output appropriately. Causes of Error Code 306Faulty External Probe: The probe [...]

Ariston 304 Fault

The Ariston error code 304 indicates a fault with the Domestic Hot Water (DHW) temperature sensor. This sensor monitors the temperature of the hot water supplied to taps and showers. A malfunction or discrepancy in the readings from this sensor can affect the boiler’s ability to correctly regulate the temperature of the hot water, potentially leading to water that is too hot or too cold. Causes of Error Code 304Faulty DHW Temperature Sensor: The sensor itself may be malfunctioning, damaged, [...]

Ariston 303 Fault

The Ariston error code 303 signals a fault with the return temperature sensor. This sensor monitors the temperature of the water returning to the boiler from the heating system. A fault in this sensor can lead to incorrect temperature readings, affecting the boiler’s ability to efficiently regulate its heating output and potentially causing safety issues. Causes of Error Code 303Faulty Return Temperature Sensor: The sensor itself may be malfunctioning, damaged, or providing inaccurate temperature readings. Wiring Issues: Problems with the wiring [...]

Ariston 302 Fault

The Ariston error code 302 indicates a fault with the flow temperature sensor. This sensor measures the temperature of the water as it leaves the boiler, and a fault implies that the sensor is either not functioning correctly or the boiler is experiencing issues that prevent accurate temperature measurement. Causes of Error Code 302Faulty Flow Temperature Sensor: The sensor itself may be malfunctioning or damaged, leading to incorrect temperature readings being sent to the boiler’s control unit. Poor Connections or Wiring [...]

Ariston 108 Fault

The Ariston error code 108 signifies a significant drop in water pressure within the boiler system, indicating that the system pressure is much lower than the required operational level. This is a more severe manifestation of low water pressure issues, potentially indicating substantial leaks or a major fault within the system’s pressure maintenance mechanisms. Causes of Error Code 108Significant Leaks: Large leaks in the heating system’s pipework, radiators, or boiler components can cause a rapid loss of water, leading to [...]
