Troubleshooting and Fixing Rheem Tankless Water Heater Code 11
To fix Rheem tankless water heater code 11, follow these troubleshooting steps:
1. Safety Precautions
Before attempting any repairs, ensure that the water heater is turned off and disconnected from the power source. Allow it to cool down completely.
