Rinnai hot water — common questions
Why is my Rinnai Infinity not producing hot water?
Rinnai Infinity units commonly stop producing hot water due to ignition failure, gas supply issues, a blocked inlet filter, or a fault code being triggered. Our technicians are trained on all Rinnai Infinity models and carry common parts — most faults are diagnosed and fixed in a single visit. Call us on 02 9344 6602, 24/7.
What do Rinnai error codes mean?
Rinnai continuous flow systems display fault codes to indicate specific problems — code 11 means ignition failure, code 12 is flame failure, code 10 relates to gas supply, and code 65 indicates a water flow fault. Note the code on your display before calling us — it speeds up diagnosis significantly.
How long do Rinnai hot water systems last?
Rinnai Infinity continuous flow units typically last 15–20 years with regular servicing. Rinnai storage tanks generally last 10–12 years. If your system is approaching this age and developing faults, we'll give you an honest assessment on whether repair or replacement is the smarter investment.
Is my Rinnai system still under warranty?
Rinnai warranties vary by model — Infinity units typically carry 12 years on the heat exchanger and 3 years on parts. All repairs must be carried out by a licensed plumber to keep your warranty valid. We use warranty-friendly diagnostics and genuine Rinnai parts where possible.
