If your Rinnai tankless water heater is beeping 10 times, it’s telling you that there’s a problem with the heat exchanger. This is a serious issue that needs to be addressed right away. The heat exchanger is what heats the water in your tankless water heater, so if it’s not working properly, your water won’t get hot.

Rinnai Tankless Water Heater Beeping 79
If your Rinnai tankless water heater is beeping 79, it’s telling you that the temperature inside the unit is too high. This can be caused by a few different things, so it’s important to troubleshoot and figure out what’s causing the issue.
One possible cause is that the inlet water temperature is set too high.
Check your settings and make sure that the inlet water temperature is not set higher than 140 degrees Fahrenheit. If it is, turn it down to a lower setting.
Another possible cause is that there is something blocking the heat exchanger.
The heat exchanger is what heats up the water inside the unit, so if there’s something blocking it, the water won’t get heated properly. Check for any debris or calcium build-up inside the unit and clean it out if necessary.
If you’re still having trouble figuring out why your Rinnai tankless water heater is beeping 79, contact customer service for help.

How Do I Fix My Rinnai Code 65?
If your Rinnai tankless water heater is displaying the error code 65, it means that there is a problem with the gas valve. This error can be caused by a number of things, including a faulty gas valve, a loose wire connection or a problem with the pressure switch.
If you’re getting the error code 65 on your Rinnai tankless water heater, first check to make sure that all of the connections are tight and secure.
If they are, then you’ll need to check the gas valve itself. Start by testing the voltage at the gas valve with a multimeter. If the voltage is low, then you’ll need to replace the gas valve.
If the voltage is normal, then you should check for continuity between the two terminals on the gas valve. If there is no continuity, then you’ll need to replace the gas valve.
Why is My Rinnai Tankless Water Heater Beeping?
If your Rinnai tankless water heater is beeping, there are a few possible reasons why. The most common reason is that the unit is not receiving enough water flow. This can be caused by a number of things, including a clogged or restricted water line, a closed shut-off valve, or a faulty pressure relief valve.
Another possibility is that the unit’s inlet filter may be dirty or clogged. This can restrict water flow and cause the unit to overheat. The inlet filter should be checked and cleaned regularly according to the manufacturer’s instructions.
Finally, the beeping may indicate that the unit’s exhaust vent is blocked. This can happen if there is lint or debris build-up in the vent pipe. The pipe should be inspected and cleaned periodically to prevent this from happening.

If there is, follow the instructions in the manual on how to clear the code.
If there is not a specific meaning for the code, then try resetting the unit by turning it off and then back on again. If this does not work, then you may need to contact a professional for help.
How Do I Reset My Rinnai Tankless Water Heater?
If your Rinnai tankless water heater needs to be reset, there are a few things you can try. First, check to see if the power supply to the unit has been interrupted. If so, simply restoring power should reset the unit.
