Time to flush it. LC indicates lime scale build-up.

How do you start the heater?


Water heaters are the part of every home in America. The one of the most common reason of that problem is your lithium battery you have used is outdated. Follow these steps to check the problem.

Closed the valve of gas from back end.
open the water heater cover
Replace lithium battery with new one
Screw in the water heater
Check it
Now it will start

Our rinnai tankless water heater is a year old and we have just started noticing temperature fluctuations when in the shower; any ideas.


Possible flow switch problem, debris in the filter, bypass valve issue or water sensor. These are pretty complicated little units so I suggest calling your contractor. The unit may still be under warranty!

No hot water - Rinnai tankless hot water heater


sounds like the water line is frozen before it gets to heater. You can take a blow dryer and try to thaw the line.You should be able to hook up a hose on the hot side of water heater. turn valve off so it wont flow into house.You can turn on hot water valve on in kitchen but you will have to thaw cold and hot line. Make sure you know where water shut off is to the house just in case a line breaks.

No hot water


An error code of 11 equals no ignition. Check gas supply, sparker, flame rod, burner and ground.

The only way that I have found to work is to place a small electric water heater close to the point of use. Yes this does defeat some of the efficiency of having a tankless water heater but if you figure electric rates are now cheaper than gas rates in some areas, it may save you money.

Another alternative is to put a domestic circulator in-line and recirc the domestic water either all the time or install a timer.

None of these options are "low-buck" options.

15' of 1/2" copper holds less than 1 gallon of water so something is wrong with the heater if it takes 3 gallons to get hot water to the faucet.

Piping of these heaters in tandem is critical. Specified by Rinnai in their design manual, the cold water should be piped to both water heaters with a back-flow presenter installed before the first heater. The hot out piping should be "Tee-d" together and going to your hot water needs.

If piped as per the manual, try turning the water off to only one of the units. Turn on a hot water tap and see if the unit stays on without interruption. Then try the same on the second unit. You may find that one unit has a bad flow control, which is shutting off the flow of water.

Question, is there any other equipment that uses propane? You indicate that the problem started after a delivery of propane after running out. If so, I suspect a blockage in either the gas train or the rinnai itself. If tou have the temperature control that regulates the water temperature, you can recall error codes to pinpoint the issue. They are optional equipment so if you can wire one in or ask your propane gas supplier if their service department has one, it will aide in the diagnosis.
