My Rinnai tankless water heater flashes 11 when calling for hot water.


Your Owner's manual should help. No manual, try MFG website, or email their customer service. Or try manualslib.com

I have a Rinnai Tankless Water Heater with a recurring failure to start problem (Code 11)


The first thing that you should do is get a water sample and have it tested for TUBIDITY. Then see what the contaminates are. This will tell you what the problem is. I seriously doubt what Rinnai is telling you is the truth. Then you need to look into a whole house water filter that has an NSF recommendation. That will stop all the issues that you are having.

Rinnai 2532 error code 10


Error Code 10 Problem: Reduced or no air supply to the water heater or there is an obstruction in extracting the flue gases out.

Solution: Make sure that the recommended Rinnai venting is used, there is no obstruction in the venting system, no reduction in diameter and lengths are per instructions. Also make sure that nothing blocks the venting system or fan, and that dip switch and condensation collar are set properly.

Good luck,

Marty

Code 11 water heater comes on for short period and shuts off


this is a tricky one, it means no ignition,which could just be a dirty flame sensor, low gas pressure, or no spark to ignite the burner. sorry but this one requires a rinnai trained service man

No hot water


The code # 11 is a code that warns of "no ignition" and the causes of this error code are too many to list. I would suggest that a qualified tech. perform a diagnostic test and repair.

This is not a task for the "do it yourselfer"
