Code 12 is low gas pressure, or that the flame sensors are not picking up a flame, try removing the flame rods, in a rinnai infinity when you pull the cover off they are right in the middle, you can use a file to clean any carbon etc off,

My rinnia moldel 2532 wont kick on

Those units rely on a flow sensor. If you have water pressure problems it wont activate. If you have hard water, the flow sensor could be bad.

Need a diaphragm for my rinnia water heater reu 56es

Sounds like tank froze with water in it. Have you checked the connections on the top of the heater they could be leaking also i would check water lines around that area for tees or 90 degree fittings. You can pull heater out and try to check it out. you can fill water heater with water to check to see if heater has a crack in it.

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.
