Controller not working


The rinnai is a computer that heats water. It is not ordinary water heater most people are familiar with, and repairs are not do-it-yourself, requiring a trained technician qualified in that brand who can diagnose both computer and water heater problems and plumbing problems.
Call rinnai for recommended local technician. Click on support tab. Note their webpage is very short on repair details, unlike companies that sell tank-type heaters... because tankless units are not do-it-yourself.
http://www.rinnai.us/tankless-water-heater
Problem might be simple blown glass fuse on circuit board or complete failure of computer and sensors.
Here is page written for Rheem tankless, that explains general complexity of tankless computers, and showing required maintenance, such as deliming each year:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
To save problems with tankless computers plus anticipated expense of maintenance and repairs, I recommend homeowner install tank-type gas water heater:
http://waterheatertimer.org/How-to-install-gas-water-heater.html
Also install one-time-use whole house surge protector, and install grounding rods to prevent further damage... lightning frequently likes the same places over and again:

Rinnai Trouble Shooting


Clean water filter.
Delime heat exchanger.

Add tempering tank to preheat cold incoming water.
http://waterheatertimer.org/Tempering-tank.html
Check for bad single-handled faucet cartridges.
http://waterheatertimer.org/Crossover.html
Don't install multi-sensor computer-chip water heater to water lines and gas line and vent pipe since tankless will develop unsolvable problems.
Contact Rinnai and hear them tell you to call service technician, only to discover there are no qualified service technicians in your area who might be able to solve problem. 1-800-621-9419
Ask why the Rainnai site has much promotional information and no service manuals. Nor does Rinnai offer forum where tankless owners can freely exchange their endless unsolvable problems for all to see.

Rinnai tankless waterheater does not begin heating water as soon as tap is opened,why?


Not sure what you mean specifically. Obviously the heater takes a few seconds to go through pre-checks and will then light. It will then take a few seconds for warm water to reach the tap depending on how far the heater is from the tap. If it is actually taking a while for it to light you need to make sure you turn the tap on full. These heaters need good water flow to fire up. Check for any filters in the tap ware and ensure they are cleaned out. I often take these filters out as they cause nothing but trouble and block too easily.

I have a Rinnai tankless gas water heater and this things beeping and flashing 12 everytime we turn on the hot water the water will get hot but you have to wait for it to stop beeping


Error 12 is failed ignition - this can be caused by many things, but normally a low gas pressure, or no gas pressure upon ignition.
Try turning the hot tap on very slowly till till the control shows burner is lit. Then turn it on faster. If it stays going with no error, you might have a faulty regulator, not opening fast enough to meet demand. Especially common with lpg models,a lot rarer on natural gas.

Rinnai tankless water heater


LC is the error code that you get when you have limescale buildup in the heat exchanger. You need to flush your heat exchanger. If you have the manual for your water heater, use it. The manual to mine is attached. The procedure for flushing it is covered on page 12. I suggest that you have a certified Rinnai plumber perform this task as it requires a ciruclating pump and some hoses that you need to connect to your water heater. If you don't perform this task, it is possible that you will need to replace your heat exchanger and this is not something covered by Rinnai's warranty.

Rinnai tankless water heater code 12


12 - Flame Failure or Poor Ground

1. Immediate code 12 is usually a defective gas valve, power supply problem, or defective fan motor wiring harness.

2. If code 12 occurs after a few seconds it indicates that proper operation was established, but then stopped unexpectedly.

3. Verify that fuel is being supplied to the unit.

4. Check for proper electrical ground. Unit must use a grounded power supply.

5. Check for flue blockage on inlet or exhaust.
