Resetting Your Ariston Boiler

To reset your Ariston boiler, you simply need to locate the reset button and hold it down for up to 10 seconds. All boilers will have a reset button, but depending on the type of boiler and the make and model, its location might look slightly different. If you can’t automatically see the reset button, then check in the menu on the display screen of the boiler. As always, remember to check your specific Ariston boiler manual for more information and the specific location for your Ariston model.

Maintenance Check for Your Ariston Boiler

Conducting an annual maintenance check on your Ariston boiler is essential to ensure it has a long life, prevent potential large future costs, and ultimately, to keep it operating safely. It is an opportunity to identify any small problems that can be easily repaired or replaced, but that could have turned into a much bigger and more costly problem. Ensuring that your boiler is performing optimally will help to keep your heating bills to a minimum, therefore, making the cost of a boiler service worth the price. An efficient boiler will take less fuel which results in cheaper bills and lower carbon emissions.

Choosing the Right Boiler for Reliability

When it comes to selecting a new boiler, it is always good to know what issues they have had in the past so that you can make a judgement on your next purchase. A boiler will eventually break, and if you are looking for a new Ariston boiler or something similar, then it’s essential to check out other boiler problems from similar manufacturers. You’ll see that the list here is very similar, and these boiler manufacturers are in the lesser-known category, similar to Ariston boilers.


In summary, Ariston boiler error codes can be complicated, but with the right knowledge, it is possible to troubleshoot any problems you may encounter. With this guide, we hope to have provided you with the information you need to fix common Ariston boiler problems and select a new boiler with confidence. If you encounter any issues or have any questions, please don’t hesitate to reach out to a Gas-Safe engineer in your area for assistance.
