Rinnai tankless hot water heater services , Rinnai tankless error codes

Do you have a Rinnai tankless hot water heater ? Tankless water heaters in general need far less in the way of maintenance and servicing than traditional tank water heaters, but they still do need to be properly maintained, and when they have issues, it is very important to know what you should do. We service and repair all tankless water heater brands. Rinnai tankless water heater troubleshooting because the self diagnostics tool provides error codes that makes it easier for home owners and plumbers, gas fitters, to diagnose and fix the underlying problems . Rinnai Error Codes Rinnai Error Code 02: No burner operation during freeze protection mode. Call a plumber. Rinnai Code 03: Power interruption during bath fill Turn off all hot water faucets/taps. Press On/Off button twice. Turn hot water back on and test. You may have to try this a couple times to reset the system. Rinnai Error Code 10: Exhaust or air supply blocked There are several things you can do before calling a plumber. Try the following: Check venting material. Is it Rinnai-approved? (See Rinnia-approved venting materials here.) If not, replace venting material or have a plumber replace it. Look for blockages in both the flue inlet or exhaust. Are the venting components properly connected? Check the condensation collar. Is it loose or improperly installed? Are the dip switches set correctly? Is the fan rotating properly, or is something blocking it? If the Rinnai error code still shows, call a plumber or an HVAC gas technician. Rinnai Error Code 11: Ignition problems Because this has to do with gas and gas lines, most people will need to call a plumber to handle this. However, these are steps the plumber will take (and you could carefully try some of these yourself): Is the gas on? Check at the water heater, gas meter or cylinder. Is the gas type and pressure correct? Is the gas line, meter and/or regulator sized properly? Is the air in the gas line? Have a plumber bleed the air from the lines. Are the dip switches set? Is the appliance grounded?  Does the igniter work? Is it operational or do you need to replace the igniter? Check the wiring harness and see if it’s the igniter or the harness. Examine the gas solenoid valves. Any open or short circuits? Remove the burner cover and examine the burners to see if they are one, properly sealed, and two, if the burner surface has condensation or debris on it. If you are not familiar with these parts and with both wiring and gas, you should hire a plumber to deal with a Rinnai error code 11. Rinnai Error Code 12: Flame failure Because this has to do with gas and gas lines, most people will need to call a plumber to handle this. However, you could carefully try some of the steps a plumber will take. Use the checklist for Rinnai error code 11 (above), and if those steps don’t fix the problem, try the following: Check power supply. Any loose connections? What is the voltage? Any voltage drops? Is the flame rod wire connected? Any problems with carbon build up on the flame rod? Check for DC shorts at components. If you are not familiar with these parts and with both wiring and gas, you should hire a plumber to deal with a Rinnai error code 12. Rinnai Error Code 14: Thermal fuse Something is wrong with the thermal fuse. You may be able to fix it by trying the following: Check for air flow restrictions. Is water flow in the circulating system low? This can cause problems related to short-cycling. Check dip switches. Anything gunking up the combustion chamber? What about the exhaust pipe? Obstructions can cause problems with thermal fuse function. How does the heat exchanger look? Any cracking or separations? Hot spots? Hot spots indicate scale build up. Flush the heat exchanger following the instructions on the owner’s manual. Check the resistance of the safety circuit. Rinnai Error Code 16: Over temperature warming This problem usually is caused by a restriction of airflow. Check for clogs or obstructions in the following: Combustion chamber Exhaust piping Heat exchanger You will also want to check for restrictions in air flow around unit and vent terminal and for low water flow in a circulating system causing short-cycling. Once you clear the obstructions and improve airflow and water flow, the problem should resolve itself. If it does not, call a plumber. Rinnai Error Code 32: Outgoing Water Temperature Sensor Fault This one is simple: carefully examine the sensor. Look for damage and scale build up. You probably have to replace the sensor if cleaning it doesn’t help. Rinnai Error Code 33: Heat Exchanger Outgoing Temperature Sensor Fault Similar to above. Carefully examine the sensor. Look for damage and scale build up and make sure the fan blade is tight on motor shaft and is undamaged. You probably have to replace the sensor if cleaning it doesn’t help. Rinnai Error Code 34: Combustion Air Temperature Sensor Fault Same as above. Carefully examine the sensor and wiring. Look for damage and scale build up. You probably have to replace the sensor if cleaning it doesn’t help. Rinnai Error Code 52: Modulating Solenoid Valve Signal Abnormal You probably need to replace the solenoid valve. First: Check modulating gas solenoid valve wiring harness for loose or damaged terminals. Measure resistance of valve coil. You may be able to resolve the problem by tightening loose terminals. Rinnai Error Code 61: Combustion Fan Failure Examine the combustion fan to see: Can the fan turn freely? Any problems with the wiring harness? Maybe it has been damaged or has loose connections? Is there a problem with the motor winding resistance?

Rinnai Error Code 65: Water Flow Control Fault You definitely need to call a plumber for this one. The water flow control valve has failed to close during the bath fill function. Immediately turn off the water and discontinue the bath fill function. Then call a plumber.

Rinnai Error Code 71: Solenoid Valve Circuit Fault You probably need to replace the solenoid valve. First: Check wiring harness to all solenoids. Measure resistance of each solenoid valve coil.

Rinnai Error Code 72: Flame Sensing Device Fault Before you call a plumber, you can try the following: Check to see if the flame rod is touching flame when the unit fires.

 Examine the wiring to flame rod for damage. Clean the flame rod with sandpaper. Examine inside the burner chamber for debris or gunk that might be blocking the flame at the flame rod. Replace flame rod.

Rinnai Error Code 00 or “LC”: Scale build up in heat exchanger.

Call a local area plumber and have them flush the tankless heat exchanger or replace the tankless heat exchanger. A lot of customers ignore this Tankless error code because it still allows the tankless water heater to continue running. You will see the display alternates between the LC error code and the temperature setting. Make sure you get the heat exchanger serviced and don’t ignore this code just because it allows you to still run the unit or you may have more serious problems down the line.
