Ariston Clas 30HE 301 Error Code

Hello All,

My five years old Ariston Clas 30HE is displaying 301 error code on the control panel. What is the matter as I have read the user manual but unable to identify the exact reason? How to fix it or should I replace my boiler?

Thank you so much

Ben

Hi Ben,

Well, 103 error codes deal with the most disturbing & common issue i.e. faulty PCB. The most costly component of the Ariston Boiler is PCB. It is a circuit board, which gives & takes signals to different electrical components in the boiler. It is important to remember that without PCB the boiler will not work properly. An error code 103 is a warning sign that PCB needs replacement. Do call a specialized boiler engineer & access the loss as at times weak wiring and connections leading to the PCB can be fixed.
