    Ariston, a prominent member of the Ariston Thermo Group, boasts a legacy of over 90 years in the industry. Founded by Italian industrial pioneer Aristide Merloni, the brand has positioned itself as a global leader in heating comfort and energy efficiency. Despite its reputation, like any appliance, Ariston boilers are susceptible to encountering issues and breakdowns over time. In this blog, we’ll delve into Ariston Boiler Error and Fault Codes to aid in troubleshooting and resolving potential issues.

    Ariston offers a diverse range of combi, system, and regular boilers to cater to various heating needs. Their combi boilers boast a power output ranging from 24 to 38kW, suitable for both small flats and large houses, depending on the chosen power output. System boilers, on the other hand, feature a power output between 18 and 30kW. Lastly, their regular boilers are available in 24kW models.

    The error codes provided in this blog aim to assist you in identifying any problems you may encounter with your Ariston boiler, facilitating easier troubleshooting and potential fixes. However, if the issue is internal or complex, we highly recommend contacting a Gas Safe Engineer for professional assistance and resolution.

    What are boiler fault codes?

    Boiler fault codes serve as alphanumeric or numeric indicators presented on a boiler’s control panel. They are designed to communicate specific issues or malfunctions within the heating system. These codes play a crucial role in aiding both homeowners and service technicians in promptly identifying and diagnosing problems, thus facilitating efficient troubleshooting and repairs. Each code corresponds to a particular fault or condition, providing users with valuable insight into the nature of the issue without requiring them to open the boiler or delve into intricate technical details.

      FAQs

      Why is my Ariston boiler heating not working?

      There are various reasons why your Ariston boiler might fail to ignite. These can include:
      faulty ignition leads
      blocked burner
      broken diaphragms or airlocks
      problem with the spark generator
      low gas pressure
      no or little gas supply
      debris in the pilot jet

      How to fix ignition failure on an Ariston boiler

      Before contacting a heating engineer, you first can check the boiler pressure to see whether it isn’t too low or too high. Otherwise, having a Gas Safe engineer take a loot at it is the best course of action.

      How to fix an Ariston faulty fan?

      First of all, you should never attempt to fix the issue yourself. This is a problem that requires the expertise of a Gas Safe engineer. The heating engineer would first check that the fan is getting the needed power, by looking at the voltmeter. If it is, then it’s very likely that a replacement fan will need to be fitted.
