Error code 11 — no ignition
Typically a gas supply problem, a dirty igniter or a failed flame rod. On properties running bottled LPG rather than mains gas, an empty bottle is worth ruling out before booking.

About the brand
Rinnai has supplied gas appliances in Australia since 1971 and is best known for the Infinity continuous flow range.
Warranty, in plain terms
Infinity heat exchangers commonly carry a longer warranty than the balance of the unit. Annual servicing and licensed installation are usually required for a claim.
Parts we carry
Igniters, flame rods, water valves, filters and error-code diagnostics for Infinity units.
Typical lifespan
A well-installed Rinnai Infinity commonly runs 15–20 years, considerably longer than a storage tank, provided the inlet filter is kept clear and gas supply is correctly sized.

Common Rinnai faults in Perth homes
Error code 12 — flame failure
The unit lights then drops out. Usually gas pressure, a partially blocked burner, or a flue restriction on a unit fitted in a tight side passage.
Cold water sandwich
Short bursts of cold mid-shower on older Infinity units. Frequently low flow through a clogged inlet filter or a mixer tap not drawing enough water to hold the burner on.
Burner and filter fouling
Units mounted in dusty or exposed positions draw debris through the inlet filter and burner. A clean and service usually restores stable output.
When replacing beats repairing
Heat exchanger failure on an out-of-warranty Infinity is the point where replacement usually wins; almost everything else — igniters, valves, sensors, filters — is economically repairable.
Our repair or replace guide sets out the full decision, and the Perth replacement cost guide explains what changes the price. Symptoms are covered in common hot water problems and the hot water FAQ.
