Rinnai Hot Water Repairs Adelaide

Common Rinnai hot water faults we fix

The Rinnai problems we are called to most often in Adelaide are:

• Error codes (11, 12, 16, 61 and others) on infinity continuous flow units
• Flame failure and ignition faults
• Water flow sensor and controller problems
• Scale build-up reducing flow and temperature
• Gas valve and solenoid failures
• Frost damage on outdoor units in the hills

Rinnai systems we service

We repair Rinnai Infinity and B-series continuous flow, plus Rinnai gas and electric storage systems. Whatever the age or model, we diagnose the fault, quote it in writing, and fix it the same day where parts allow.

Repair or replace?

If your system is under 8 years old and the fault is a part, repair is almost always the right call. If it is leaking from the base, producing rusty water, or past 10-12 years, we will give you a fixed quote on replacement too – including heat pump options where current SA rebates apply. No pressure, just the honest numbers on both.

What it costs

Most Rinnai repairs are a single call-out plus parts, with a written fixed quote before any work starts. There is no separate callout fee in the quote and no surprises on the invoice. We also offer pensioner consideration.
