    Tankless WH error code

    I am on my second GD trailer and currently have a Reflection 303RLS which I love for the most part. I am ready to throw my tankless water heater out. Twice it has let me down and now I’m getting an error code 05. I’ve blown out a small tube that holds condensation to no avail after reading others have had the same issue.

    There are several factors that need to be met for a tankless water heater to work.

    Water flow has to meet a minimum requirement, as well as detected voltage, since it is a 12 volt fired appliance.

    Are you plugged into shore power and is the water supply strong?
