Rinnai Tankless Water Heater Code 11

Have you ever saw anything like Rinnai tankless water heater code 11? If you have not got one installed in your place, you should get one installed (only if you have the money, the place, and the time, of course). Water heaters will change your life like they can change cold water into a warm or hot one.

But, like any other invention made by humans (and gods alike), the water heater is still exposed to the ‘darker side of reality. Without proper care and treatment (and sometimes even with proper treatment), water heaters will break down and be unusable.

When that happens, there are two things you can do:

1. Buy a new one (which is the easiest compared to the two)

2. Try to fix it up.

Now, I am not saying that fixing a water heater is nigh impossible – it is actually pretty easy if you know what you are doing –  but diagnosing the problem? Now that is the real problem.

Without proper knowledge of the construct of a water heater, you would not get a correct diagnosis of the problem. You would not know which part was broken because of what, and you would not be able to fix it.

A Guide to the Broken Heaters: Rinnai Tankless Water Heater Code 11

To counter that, some water heater manufacturer sends out manuals to come along with the water heater. Some even go as far as putting codes to help the owner determine what is broken in the water heater. One such manufacturer is Rinnai, a famous appliances manufacturer.

For better or worse, Rinnai put out some codes that can help you find out what is wrong with your broken water heater.

There are several error codes, but today I will talk about code 11, which is a common problem found in Rinnai water heaters. Sure, you will find the manuals’ guidance, but not all people are blessed with the manuals (be it because they lost it or because they bought it somewhere illegal), so if you are one of the second disposition, then proceed with this article.

Code 11? What does that mean?

It means that your water heater broke (well, obviously) thanks to the heating system that is not working. Why? Perhaps it is because you have no gas supplies left in your tank, perhaps because your ignition system is not working well.

Why again? Who knows. There is always a probability that the water heater in your hand is not even working in its supposed way from the moment you bought it. Very unfortunate.

What can I do to remedy code 11?

The first thing you should do is check and re-check. Always check for the gas supply first before you delve deeper into the machine. Probably your machine only ran out of gas. When that happens, resupply it with a brand new gas, and you are good to go.

(WARNING: turn off all water taps and water controls in your house before you do this

However, when the gas is present and the ignition would not start, then there is something else that you should look at: the wiring of the heater. There goes a time where the wiring just goes haywire, and because of that, the water heater would not even turn on. If you encountered something like that, open the panel and do some re-wiring. I am not that masterful in wirings’ art, so you may want to look at other guides.

If anything else fails and you cannot find the source of the problem, the easiest thing would be to call a Rinnai expert to your house. I know this can be costly, but this is possibly the best option if you do not want to buy another brand new water heater.
