Error code 11 — no ignition
Typically a gas supply problem, a dirty igniter or a failed flame rod. On LPG homes around Lara and the rural Bellarine it is often simply an empty or run-down bottle, which is worth ruling out before booking.

Rinnai hot water — Geelong.
Rinnai's Infinity continuous flow units are a Geelong favourite. Our team carries common Rinnai parts for most repairs.
What we service
Every Rinnai system.
- Continuous flow (Infinity)
- Gas storage
- Heat pump (Enviroflo)
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 Geelong 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.
Frost damage
A real risk on frosty inland Geelong mornings. Infinity units have frost protection but only while powered — units left switched off at the isolation point through winter can split internally.
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 Geelong replacement cost guide explains what changes the price. Symptoms are covered in common hot water problems and the hot water FAQ.
