I am working on a monitor 2400. heater will run normal until it reaches set temp. when it goes to mid burn the flame goes out and code 14.


E14 Flame failure: There are obstacles at circulation air inlet or outlet. Fan cage is clogged with dust. Gas pressure dropped when other gas appliances are turned on. (this may also apply to K1 fueled units if you have another K1 based heater)

Here are the rest of the fault codes I found:

Digital Display Reason of indication Trouble Point
E01 At pre-purge, flame rod is sensing flame when there should be none. Flame sensing circuit, grounded flame rod or pinched wire. E05 After power on, power supply to the microprocessor timing circuit is incorrect. Timer clock circuit bad or power cycles (hertz) to unit above or below acceptable levels.
E06 A starting of operation, the circuit to drive photo triac of solenoid pump is malfunctioning. Solenoid pump control circuit has a malfunction.
E08 Revolutions per minute of combustion blower are malfunctioning. Combustion blower or combustion blower control circuit has a malfunction.
E13 No ignition. Failure of ignitor, solenoid pump or circuit board. Incorrect wiring or flame rod touches to burner parts. Air pressure switch or overheat open.
E15 Power supply voltage too low. Voltage too low or power detector circuit has a malfunction.
E16 Load failure of combustion blower motor Flue pipe is restricting air flow.

Error Code 90 Solution


Over time after about 5 to 6 years many Noritz heaters tend to display error code 90 and stop working. The unit has to be shut off and back on for it to work again for a short time. Error code 90 is indication of abnormal combustion and can have a few causes, including blockage in the exhaust vent. However the problems lies mostly with the combustion fan. that is the fan that you hear when the unit is running. It is unable to deliver enough air to normal combustion.
Replace the fan and while doing it clean the air pathway with compressed air. In addition remove the ignition and heat senors (all in one assembly, in the middle of the unit) and sand them very slightly with very fine sandpaper (400 or higher) to remove build up on them.
While the fan is being ordered you can at your own risk operate the unit with the cover slightly open (about 2 in.) at the bottom and the unit will run without code 90. It is highly recommended to hire a trained technician for the above work as gas appliances pose a significant danger to human life and property if not installed or maintained properly.

Rheem tankless water heater error code 11


Error 11 is ignition failure, or insufficient gas, or defective sensor, dirty combustion parts.
Do the yearly required maintenance such as cleaning the combustion parts, and error code will probably be solved.
Problem is Rheem does not post service manuals for people to learn how to service their equipment without calling service tech.
Copy following link for Rheem troubleshoot resources
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

The cost of yearly maintenance will easily eat away the expected yearly savings of $100 for typical family of 4.

E4 code on a bosch ghw 715 control unit


Before calling service technician, open following link for Bosch troubleshooting resources:
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

Error codes are starting point for troubleshooting, and solutions vary by model and unit.
E4 is Backflow temperature sensor over 309 degrees F. Appliance will close burner and lock.
Check combustion air and backflow vent piping for blockage.
Check if secondary fan connections are disconnected.
Check venting specifications are met. Long vent lengths, venting with more than three elbows, blocked vent or combination venting may cause this failure.
Check sensor resistance

My laser 30,had error code EE8, but i was able to restart..my house is full of the smell of diesel, took off fan cover doesnt move when turned on but did after i turned it off...choking on fumes in alaska


EE8 is the code for combustion blower failure. I'm not sure which fan you checked. You can't see the combustion blower fan. It is inside the black plastic cover on the back side of the heater near the bottom. You can see the motor for it from inside the heater. The blower has a sensor to determine fan speed to control the amount of airflow to the burner. There could be a problem with the sensor. When you turn the heater on the first thing you should hear is the combustion blower start up and run. On the smaller heaters they are very quiet and sometimes hard to hear. Start the heater and see if the blower starts. If it doesn't remove the front cover and locate the blower motor so you can check the wires going to it. I have seen wires that mice have chewed off. Otherwise you may need a need blower motor. If it is running then the sensor is possibly bad and you would also need a new blower motor. Also make sure the exhaust pipe isn't blocked since you say the house smells like diesel. Let me know what you find. nitensheaterservice@earthlink.net

I rent and have a Rinnai Energy saver 556F. I have it at 64 and the light blinks for 68. I would like to know why. It is 56 out side now thank you


Shadow,

The 68 you see is an error code. It means you have had an over heat situation. You should be able to clean the filter and fan area and restart. Turn the heater off and on again, that should reset everything and you should be good.

My tank says I have 32 gallons left but the heater won't work (rinnai 556f). It turns on for about 15 seconds and the light on the power button turns red and starts blinking. What does this mean?


If you hold down the economy button and the up and down arrow buttons for 5 seconds the unit will start an error code display. Get a helper and yell out the numbers when they start blinking. Post the error codes and we can help you
