Common Rinnai Error Code 55 Solutions

If you’ve encountered Rinnai Error Code 55 on your tankless water heater, don’t panic. There are several common causes for this error, and with a few troubleshooting tips, you can resolve the issue and restore your hot water supply. Let’s take a look at some possible causes and how to fix them:

1. Insufficient Power Supply

One of the main causes of Error Code 55 is a lack of power reaching the water heater. Start by checking if there is power outage in your area. If the power is on, make sure that the water heater is properly connected to a reliable power source. Check for any loose or damaged wiring and tighten or replace as necessary.

2. Tripped Circuit Breaker

An overloaded circuit can cause the circuit breaker to trip, cutting off power to the water heater and triggering Error Code 55. To fix this issue, locate the circuit breaker that controls the water heater and reset it. If the breaker keeps tripping, it’s a sign of an underlying electrical problem, and you should consult a professional electrician for further assistance.

3. Low Gas Pressure

In some cases, Error Code 55 can be triggered by low gas pressure. Check the gas supply to the water heater and make sure the gas valve is fully open. If the gas pressure is consistently low, you may need to contact your gas provider for assistance.

4. Faulty Flame Rod

A faulty flame rod can also cause Error Code 55. The flame rod is responsible for detecting the presence of a flame. If it’s dirty or covered in soot, it may not work correctly. Carefully clean the flame rod using a soft brush or cloth to remove any buildup. Ensure that the rod is properly positioned and reassemble the unit before turning it on.
