Install the proper Therm-X-Trol® or equivalent thermal expansion tank Relief valve 2. Thermal expansion tank set improperly 3. City pressure too high 2. Ensure precharge air pressure matches static water pressure 3. Install a Pressure Reducing Valve (PRV) if city pressure is over 80psidripping or opening 4. System over temperature 4. Determine cause of over temperature condition and correct problem 5. Faulty relief valve 5. Replace relief valve ER1 message on Smart Control™ 1. Temperature sensor unplugged 2. Temperature sensor cut or faulty 3. Water in therm-well 1. Sensor is unplugged from factory. Plug into Smart Control™ receptacle 2. Replace sensor wire (thermistor) 3. Replace therm-well Discolored water at faucet 1. Poor water quality 2. Sediment or suspended particles 1. Have water tested for contaminants. Typical problems are: Blue/green color = copper discoloration due to low pH Black staining/sulfur odor = hydrogen sulfide White deposits = hard water Red staining = high iron levels 2.
