This can be a frustrating problem to deal with, as it can disrupt the hot water supply in your home. However, before you panic or consider replacing your water heater, there are steps you can take to resolve the issue and get your tankless water heater working efficiently again.
In this article, we will discuss the common causes for Rheem tankless water heater code 29 and provide you with troubleshooting tips and solutions.

Common Causes and Solutions for Rheem Tankless Water Heater Code 29
When encountering a code 29 error on your Rheem tankless water heater, it is essential to identify the common causes and implement the appropriate solutions. This ensures the efficient operation of your water heater and prevents any further damage.
Clogged Condensate Drain Line
One of the primary causes of a code 29 error is a clogged condensate drain line. Over time, debris and sediment can accumulate in the drain line, restricting the flow of condensation. This leads to insufficient drainage, triggering the error code. To resolve this issue:
- Turn off the power supply to the water heater.
- Locate the condensate drain line and assess if it is clogged.
- If clogged, use a small brush or pipe cleaner to remove the debris gently.
- Ensure the condensate drain line is clear of any obstructions and allows for proper drainage.
- Turn on the power supply and check if the error code 29 persists.
Problem with the Neutralizer
Another potential cause for a code 29 error is a problem with the neutralizer not draining properly. The neutralizer is responsible for neutralizing acidic condensation before it is discharged. If the neutralizer is not draining correctly, it can result in a code 29 error. Here’s how to address this issue:
- Turn off the water heater and disconnect the power supply.
- Inspect the neutralizer and check if it is damp or wet.
- If wet, carefully dry the neutralizer using a cloth or towel.
- Ensure the sensor wires on the neutralizer are dry and not causing any interference.
- Reconnect the power supply and turn on the water heater to see if the error code persists.
Other Potential Causes
In addition to the above, incorrect condensate line piping, wet sensor wires on the neutralizer, or a defective control board can also contribute to a code 29 error. If the previously mentioned solutions do not resolve the issue, it’s recommended to consult with a professional water heater technician. They will have the expertise and knowledge to diagnose and repair the problem accurately.
