If one or both of the temperature adjust buttons on your Reliance Water Heater are stuck, press and release both buttons several times and cycle the water heater power off and on. If the issue persists, replace the gas control valve/thermostat.
What to do if my Reliance 100 Water Heater detects flammable vapors?
If the self-diagnostic check on your Reliance Water Heater detects flammable vapors, do not touch any electrical switches or use any phones in the building, and do not attempt to light any appliances. Smell around the water heater for gas leaks at the gas control valve/thermostat or in the supply gas lines, and check for flammable vapors in the area. Inspect the area for substances like gasoline, paint thinners, or cleaners. Remove any potential sources of flammable vapors from the area and store them properly. For further assistance, call the technical information support phone number shown on the water heater labeling.
Why does the blower run continuously on my Reliance Water Heater?
If the pressure switch circuit remains open for more than 5 seconds after the blower starts on your Reliance Water Heater, and the blower runs continuously, make sure the air pressure switch sensing tube is properly connected at both ends and is not kinked or damaged. Also, ensure the correct size of vent and intake air pipe (for direct vent products) was used according to the installation instructions. Make sure that the maximum number of elbows or maximum equivalent feet of vent or intake air pipe has not been exceeded per the installation instructions. Finally, check for any obstructions in the vent or intake air pipe.
How to fix an open igniter circuit in my Reliance 100 Water Heater?
If you have an open igniter circuit in your Reliance Water Heater, first check the wiring to the hot surface igniter assembly and replace the igniter assembly if the wiring is damaged or worn. Then, check the resistance of the igniter at the igniter assembly plug; it should be between 11 and 18 ohms at room temperature (77° F at plug end). Replace the igniter if it is open or shorted. Also, check the igniter assembly plug and the socket on the gas control valve/thermostat for a good connection. Replace the igniter assembly if the plug is worn or damaged. If the igniter assembly socket on the bottom of the control is worn or damaged, replace the gas control valve/thermostat.
What to do if the blower doesn't start on my Reliance 100 Water Heater?
If the pressure switch circuit remains closed for more than 5 seconds after the heating cycle begins on your Reliance Water Heater and the blower doesn't start, ensure the air pressure switch circuit wiring is correct and the air pressure switch is not jumpered. If the issue persists, replace the air pressure switch.
How to resolve LDO lockout on my Reliance 100?
If the air pressure switch circuit is opening repeatedly during one heating cycle on your Reliance Water Heater, resulting in an LDO (Lint, Dust, and Oil) lockout condition, take the following steps: * For models with a dilution air intake screen on the blower assembly, check and clean the screen. * For models with a combustion air intake screen on the base ring (bottom) of the water heater, check and clean the screen. * Ensure that the intake air screens, if equipped, are not obstructed.
What does it mean when my Reliance Water Heater shows a gas valve driver circuit error?
If the self-diagnostic check on your Reliance Water Heater detects a problem with the gas valve driver circuit, internal microprocessor, or other internal circuits, turn the power off for 10-20 seconds and then back on to clear the error codes. If the error codes persist or cannot be cleared, replace the gas control valve/thermostat.
What to do if my Reliance Water Heater senses a flame signal out of sequence?
If your Reliance Water Heater senses a flame signal out of proper sequence, turn the power off for 10-20 seconds, then turn it back on to clear the error codes. If the error code persists, replace the gas control valve/thermostat.
How to fix an open or shorted FV sensor on my Reliance 100?
If the FV (flammable vapor) sensor on your Reliance Water Heater is either open or shorted, turn off the power to the water heater. Ensure all FV sensor wiring, the igniter assembly plug, and the igniter assembly socket on the bottom of the Intelli-Vent control are making good contact. Repair or replace any worn or damaged components that are not making a good connection. If the problem persists, replace the FV sensor.
Why did my Reliance 100 activate the ECO (energy cut off)?
If the water in your Reliance Water Heater tank exceeds the maximum allowable temperature, activating the ECO (energy cut off), turn the power off for 10-20 seconds, then turn it back on to clear the error codes. If the error code persists, replace the gas control valve/thermostat.
