Rinnai Error Code 52

What Does a Rinnai Hot Water Error Code 52 Mean?

Should your Rinnai continuous flow hot water heater be showing an error code 52 on the monitor, this is a sign that the gas modulating valve is faulty. A Rinnai fault code 52 will require the services of a fully qualified professional to rectify, due to the nature of the repair.

To ensure that the fault code 52 is not a trip of the system, before making a service call you should attempt to clear the code yourself in case it has appeared in error. You can try to clear any Rinnai error code that may show up on your monitor by simply turning the hot tap off and then on again, and by also pushing the monitor’s on/off button to off and then on again. If the Rinnai fault code 52 remains then it is time to call in an expert.

Rinnai Fault Code 52 Repairs

When it comes to resolving a Rinnai error code 52 on your Infinity continuous flow hot water system we will investigate the cause, including; checking the wiring harness for any damaged or loose connections in relation to the POV back to the PC board.

If this is all in order the next step will be to unplug the POV valve and check the resistance readings. The voltage to the POV will also be checked. As a last resort, if the above steps do not rectify the Rinnai fault code 52 warning then the PC board will need to be replaced.

You should never attempt to remedy a Rinnai fault code 52 on your hot water system if you are unqualified to do so. Trying a DIY repair is extremely dangerous and could void your appliance warranty as well as endanger your home’s insurance policy should something go wrong.

So quick!

Jayden was sent to fix my washing machine taps. He was polite and friendly, and explained what needed to be done. It was a bit more expensive than I expected, but from my call for service to the job being completed was only two hours. I would definitely recommend!
Laura M., VIC 5 stars rating

Laurence did a super efficient job

Laurence came out and replaced my damaged section of drain. He was very quick and efficient, did a great job. Informed us about what we need to know about our drain. Cleaned up after himself. Highly recommend Laurence to anyone that needs plumbing done, would definitely use again.
