Frequently asked questions
Is this electrode compatible with the Ariston Alteas One Net 30 and 35?
Yes. Ariston part number 65116556-03 is confirmed for the Alteas One Net 30 with GC No. 47-116-91 and the Alteas One Net 35 with GC No. 47-116-92, for the appliance editions dated 13/12/2019.
Which Ariston Genus One Net boilers use electrode 65116556-03?
This electrode is confirmed for the Genus One Net 24, Genus One Net 30 and Genus One Net 35 editions dated 13/12/2019. Check the corresponding GC number against the compatibility list before ordering.
How can I confirm that 65116556-03 is the correct replacement?
Check the number printed on the existing component and compare the boiler’s full model, GC number and edition date with the compatibility information above. The complete MPN, including the -03 suffix, should be matched carefully before purchase.
What symptoms may indicate an ignition or detection electrode problem?
Possible symptoms may include unsuccessful ignition attempts, intermittent ignition, ignition lockouts or the flame being lost shortly after lighting. These symptoms can have several possible causes, so they do not automatically confirm that the electrode is defective. A qualified engineer should diagnose the boiler before replacement.
Does this component require professional installation?
Yes. Ignition and flame-detection components form part of the boiler’s combustion and safety system. Installation and testing should be completed by a suitably qualified Gas Safe registered engineer.
