6 Steps For Rheem Hot Water System Troubleshooting

by | Nov 19, 2021 | Plumbing

Hundreds upon thousands of Australians did exactly what the ad cheerfully sang to them, and “installed a Rheem”. And they, and you, made a wise choice. It’s been perhaps the premier choice in the bustling Australian hot water market not for years but for decades – all the way back to before World War II, as it happens. But while Rheem clearly knows what it’s doing, that doesn’t mean you don’t need to know a little about Rheem hot water system troubleshooting.

If you have “installed a Rheem“, you were spoiled for choice. You may have a traditional gas hot water system, an all-reliable electric hot water system, a slick and handy continuous flow unit, a next-generation heat pump system for a much greener environmental footprint, or perhaps even a solar unit that really puts more power in your hands – direct from that free sunlight all around us.

Has something gone a little wrong with your normally-reliable Rheem system? Without further ado, let’s get stuck into some super-simple Rheem hot water system troubleshooting:

1. Seeing an error code?

If you have a popular instantaneous Rheem hot water unit, most faults are covered by the helpful error code system – just read it out from the LED display on the front. If ’14’, the system has overheated. If 74, the system is no longer communicating with the remote controller. If 90, the fan motor is malfunctioning. In all those cases, and dozens more, the only real option is a service call, but many other faults may be rectified by:

  • Checking the gas supply
  • Cycling power off and on again.

2. Seeing a flashing light?

Rheem heat pumps may not show you an error code, but the monitor may display a flashing light. What does it mean? It depends on how it’s flashing! The meaning of the particular flashing you’re seeing can easily be checked in the owner’s guide, and if you can’t easily remedy the situation, a service call is inevitable.

3. Pilot light gone out?

Luckily, you’ve run across an issue with your gas Rheem hot water system that is very easily to fix. It’s just a matter of turning the main gas supply knob to the off position, and then walking away for a few minutes so any residual gas can flow itself out of the system. When you get back, turn the knob to the pilot position, push it all the way in, hold it for up to 30 seconds, and then start pressing the igniter button until you hear or see the re-lighting occur. Hold the knob down for a little longer so make sure the flame remains lit. That’s it!

4. Water leaking from the relief valve?

If it’s just a small quantity of water that’s dripping out of any valve on your Rheem unit, that’s entirely normal – in fact, the valve is just doing what it does. But if you’re filling up an entire bucket every day or so, there’s probably something wrong – so it’s time to make that service call and see what’s the deeper issue with a leaking hot water system.

5. Water temperature fluctuating?

Slightly inconsistent hot water temperature from your continuous flow heater is simply a common feature of the technology, but if the problem is really noticeable then read on. What could be happening is that any water-saving measures you have in place – flow restrictors, or water-saving taps – may be tricking your Rheem into thinking there’s no particular need to heat it. But that’s easily fixed by asking a local Melbourne plumber about increasing your hot water flow rate.

6. Water temperature is too hot?

When you’re hot water isn’t hot enough, you could be dealing with a faulty tempering valve that will need to be fixed. But what if the water is actually too hot? This is actually the job of the tempering valve to regulate, as your water should be no higher than about 60 C. Also possible is that the thermostat needs to be turned down a little, which is quite easy to do yourself with a gas tank system.
