Rheem Models We Service and Repair
Our licensed gas fitters are experienced with the full range of Rheem hot water systems found in Melbourne homes.
Rheem Gas Storage Hot Water Systems
Rheem gas storage systems are the most common Rheem product we service across Melbourne. These systems heat water in an insulated steel tank using a gas burner at the base of the unit.
Common models: Rheem 125L, 135L, 160L, 250L, 315L, 340L gas storage systems
Rheem Continuous Flow Hot Water Systems
Rheem's continuous flow range delivers hot water on demand with no storage tank. The Rheem Continuous Flow series is a popular choice for larger Melbourne households.
Common models: Rheem Continuous Flow 12, 16, 20, 27
Common faults
- No hot water ignition failure, flow sensor fault, gas supply issue
- Error codes on the display varies by code (see fault section below)
- Insufficient hot water temperature unit undersized for flow rate, scale build-up on heat exchanger
- Inconsistent temperature flow sensor fault, thermistor fault
- Pilot light issues on older continuous flow models
Rheem Electric Storage Hot Water Systems
We also service Rheem electric storage systems including element failure, thermostat faults and pressure relief valve replacement.
Common models: Rheem 250L, 315L, 400L electric storage systems
Rheem Solar Hot Water Systems
Rheem solar hot water systems with gas or electric boosters. We service the booster components, storage tanks and associated fittings.
Common faults
- Pilot light not staying lit: thermocouple failure
- No hot water: thermostat fault, gas valve fault or pilot failure
- Leaking from the pressure and temperature relief valve
- Leaking from the tank body: internal corrosion (replacement required)
- Rust-coloured hot water: depleted sacrificial anode or internal corrosion
- Unusual noises: sediment accumulation in the tank
- Insufficient hot water: undersized system or thermostat fault
Common Rheem Hot Water System Faults We Repair
What you notice: You turn on the hot tap and only cold water comes out.
Common causes (gas storage)
- Pilot light has gone out attempt to relight following the instructions on the unit
- Thermocouple failure the pilot lights but goes out when the button is released
- Gas supply issue check your meter is on and other gas appliances are working
- Faulty gas valve
- Thermostat fault
Common causes (continuous flow)
- Gas supply issue
- Ignition failure error code on display
- Flow sensor not triggering the burner
- Faulty gas valve
What to do: For gas storage systems, attempt one relight following the unit instructions. For continuous flow systems, check for an error code and try one reset. If the problem persists, call us for a same-day diagnosis.
What you notice: The pilot lights when the button is held but goes out when the button is released.
Cause: Almost always a thermocouple failure. The thermocouple is the safety device that detects the pilot flame and holds the gas valve open. When it fails, the gas valve closes and the pilot extinguishes.
What to do: This is a straightforward thermocouple replacement. We carry Rheem thermocouples for all common models on the van. Most Rheem thermocouple replacements are completed within an hour. Call us for a same-day repair.
What you notice: Water pooling around the base of the unit, dripping from a valve on the side or top of the unit, or visible water staining on the outer casing.
Common causes
- Pressure and temperature relief valve (PTRV) dripping, the most common cause. Indicates either excess system pressure or a failing valve.
- Inlet or outlet connection leak
- Internal tank corrosion causing pinhole leaks in the tank wall, requires replacement
- Drain valve or expansion valve leak
What to do: A dripping PTRV should not be ignored, it is a safety-related issue. Turn off the cold water supply to the unit at the isolation valve and call us. If the leak is from the tank body, the system requires replacement.
What you notice: The hot water from your taps has a brownish, rust-coloured or metallic tinge.
Cause: The sacrificial anode in the tank has been depleted and the steel tank is corroding internally. Once internal tank corrosion is established, the only solution is system replacement.
What to do: Call us for a same-day assessment and replacement quote. In most cases we can supply and install a replacement Rheem system the same day.
What it means: Ignition failure: the system has attempted to ignite but failed to establish a flame.
Common causes
- Gas supply issue check meter and other appliances
- Faulty igniter
- Dirty or blocked burner
- Faulty gas valve
- Low gas pressure
What to do: Check gas supply. Try one reset by turning the unit off at the power switch for 30 seconds and back on. If the code returns, call us.
What it means: Flame failure: the burner lit but the flame went out during operation.
Common causes
- Faulty flame sensor
- Gas supply interruption
- Dirty burner
What to do: Try one reset. If the code persists, call us for a flame sensor diagnosis.
What it means: A temperature sensor fault on the heat exchanger or the outlet water temperature.
Common causes
- Faulty thermistor (temperature sensor)
- Wiring fault to the thermistor
- PCB fault
What to do: Professional diagnosis required. Call us.
What you notice: Popping, rumbling, banging or hissing from the hot water system.
Common causes
- Popping or rumbling Sediment and scale accumulation in the base of the tank. As the burner heats the water, steam bubbles through the sediment layer.
- Hissing Steam escaping from the PTRV: indicates excess system pressure or a failing valve.
- Banging Thermal expansion of pipes.
What to do: Rumbling from sediment indicates the anode should be inspected and the system serviced. Hissing from the PTRV is a safety issue: call us promptly.

How Long Does a Rheem Hot Water System Last and What Maintenance Does It Need?
System Lifespan
| Rheem System Type | Expected Lifespan |
|---|---|
| Gas storage: glass-lined tank | 8 to 12 years |
| Gas storage: stainless steel tank | 10 to 15 years |
| Gas continuous flow | 15 to 20 years |
| Electric storage | 8 to 12 years |
| Solar (tank) | 10 to 15 years |
The most important maintenance task: Sacrificial Anode Replacement:
Every Rheem gas and electric storage hot water system contains a sacrificial anode rod that corrodes preferentially to protect the steel tank from rusting. Rheem recommends anode inspection every 5 years and replacement when depleted.
A system with its anode maintained will regularly achieve the upper end of the lifespan ranges above. A system with a depleted anode will begin corroding internally and fail prematurely.
If you do not know when your Rheem system's anode was last inspected or replaced, call us, we can assess it during any service visit.
