Mysolution relates only if you are on LPG/bottleg gas. I have had many problems with the gas regultor actually on the initial supply line near the bottles sticking. Error code 11 is usually simply a gas supply issue and not a fault with the heater itself. Just rule out that before you start messing with the heater itself. Causes inside the heater would be either gas valve (unlikely) or PCB. Both are not normally intermittent. Try running something else on gas if you have anything and then turn on the heater.

Rinnai 1004 F Error Code 11


Code 11 is that the unit is trying to light but does not sense a flame after 5 seconds. Usually means you have run out of gas if you are bottled gas. Check your bottles are turned on if you are on LPG, you might need to change over manually. Have you anything else on gas?

Error code 11 on a Rinnai energysaver 556FTR


Rachel,

The 11 code means Missed Ignition. This is a broad error code. It just means the stove did not light when it was supposed to. I would check the fuel first to be sure the valve is on and you have gas. Next, try to start the stove with the room dark. Look into the window to confirm a sparking. This is the igniter. At the same time be sure the combustion motor is running. You should be able to hear it and feel the stove to confirm this. If the motor does not turn or the flue is blocked you will not get any gas to flow. Look outside to confirm the flue is not blocked.

Keep us posted,

Tom

Can't get hot water heater to work - Rinnai Infinity 18


If you can get to the gas valve make sure it is in the on position and not in pilot or off. Does it sound like
a spark ignition system? Even though you say the gas valve is on, by code thered should be a gas shutoff valve located within site of the unit. Follow the
gas pipe until you find such a valve and make sure its on

I have a trouble code 11 on my Rinnai model 2532 water heater which indicates no ignition. I checked for gas supply by turning the furnace on which is approx. 1 ft. away, it works. The water heater is...


11 is a ignition failure code. Could be alot of things, I suggest calling a tech who has repaired these before. Pull the front cover off and have a helper turn on a hot water faucet. Look thru the viewing window to see if the unit is firing then going out. If not, clean out the water filter on the inlet side of the plumbing. You will need to turn off the water supply prior to cleaning it. If the unit fires but shuts off seconds after ignition, you may have a dirty or bad sensor. Call a proffessional at this point. Sorry

Rheem/GE power vent water heater, pilot lites, but not the main


I would check to see if the switch on the blower pressure sensor is closing...When T-stat calls for flame, the circuit starts the blower, then the blower pressure sensor switch closes to allow the main gas valve to be powered.

Code LC, I cleaned the filter, won't stop beeping


you need to flush out the rinnai. to do this you will need 4 gallons of white viniger & a circulating pump. #1 disconnect the power. #2 close both incoming & outgoing water valves under the unit. #3 conect a drain hose to the out going flush valve ( flush valves are under the unit & have brass caps) #4 connect pump outlet hose to ingoing flush valve. #5 put pump incoming hose & drain hose from outgoing flush valve in a 5 gallon bucket. #6 pour 4 gallons of vinager into the bucket. #7 open both flush valves. #8 turn on the circulating pump & let viniger pump in the incoming flush valve through the rinnai & out the outgoing flush valve back into the bucket for 45 min. #9 disconct pump from incoming side & close incoming flush valve.( don,t close outgoing vaves at this time) #10 put out going hose in empty bucket. #11 open incoming water to flush viniger out of unit. # 12 disconct outgoing hose , close outgoing flush valve & open outgoing water valve. #13 clean filter & turn on power.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

Error code 11 on my rinnai


A code 11 also means that it might not be getting any gas. On thr right side of the unit you will find a small door. open it up and make sure the valve is in the open position. If it is, you should contact your gas company to come and diagnose what is going on. The Rinnai is not a do it yourself fix it type of heater.
