Gas control valve failure
The signature AquaMAX fault. The pilot stays lit but the burner will not fire, so the tank slowly goes cold. It is a licensed gas repair, not a homeowner fix.

Common AquaMAX faults in Darwin homes
Pilot outages in exposed positions
Outdoor G Series tanks on exposed coastal blocks around Nightcliff and Fannie Bay can lose the pilot in strong build-up winds — a draught shield or repositioning often solves what looks like an appliance fault.
Sediment rumble
Distinctive kettling from the tank base after years of service. Flushing helps on younger units.
Tempering valve failure
Scalding water at the bathroom tap. A safety fault, replaced same visit.
When replacing beats repairing
Because AquaMAX stainless cylinders outlast their gas controls, replacing a control valve on an otherwise sound tank is normally good value — the exception is a unit already past twelve years.
Our repair or replace guide sets out the full decision, and the Darwin replacement cost guide explains what changes the price. Symptoms are covered in common hot water problems and the hot water FAQ.
