In this article, we will discuss what causes the Rinnai Error Code LC Scale Build-Up problem, how to fix it, and how to prevent it from happening in the future.

What Causes the Rinnai Error Code LC Scale Build-Up Problem?

There are several factors that can contribute to the Rinnai Error Code LC Scale Build-Up problem:

Hard Water: Hard water contains high levels of minerals, which can cause scale buildup in your pipes and appliances.
Lack of Maintenance: If you do not regularly flush your water heater, it can lead to scale buildup in the heat exchanger.

How to Fix the Rinnai Error Code LC Scale Build-Up Problem?

If you encounter the Rinnai Error Code LC Scale Build-Up problem, there are a few steps you can take to fix it:

Turn off the power to the water heater: Before attempting any repairs, make sure to turn off the power to the water heater to prevent electrical shock and to prevent the water heater from heating cleaning solutions.
To remove the scale buildup from the heat exchanger, you will need to flush the unit. We recommend the Whitlam Flow-Aide System Descaler Kit. Use the descaling solution to dissolve the scale buildup, and then rinse the heat exchanger thoroughly with water.
