Ariston Boilers Guide

Hi All

I have an Ariston boiler model Clas 30HE, and it is getting a bit crazy during last 2 weeks. Boiler first shows SP1, then E501 and it switches itself off. Resetting helps but only for few hours, when situation repeats. I have no idea what is wrong, except finding in manual a message that codes starting with 5 correspond to ignition problems. How to fix it?

Thanks

Luke

Hi Luke 

SP1  stands for “first ignition attempt” failed and E501 stands for “no flame detected”.  There are a lot of components that may cause this failure and I am afraid that most of them are extensive: gas valve, PCB, fan, detection electrode. I really think it is the best to call a specialist in your case. Someone will come, investigate and in less than an hour you will know what is the problem and how much will it cost to fix it.
