Here is a breakdown of these informative features found in the manual and on the unit itself.
| Problem | Possible Cause | Remedy | |------------------------------|------------------------------------|--------------------------------------| | No hot water | Pilot out | Relight per lighting instructions | | | Thermostat defective | Replace gas valve/thermostat | | | Gas supply off | Open valve, check pressure | | Water not hot enough | Thermostat set too low | Adjust to higher setting | | | Sediment buildup | Flush tank | | | Undersized heater | Reduce demand or upgrade | | Rumbling/popping noise | Heavy lime scale | Flush, treat with delimer | | Pilot won’t light | Air in gas line | Bleed lines (call gas co.) | | | Thermocouple faulty | Replace (0.5–1.0 mV minimum) | | Burner won’t stay lit | Bad thermocouple or magnet | Replace gas control or thermocouple | | Water leaking from tank | Tank corrosion | Replace water heater | | | Loose drain or T&P valve | Tighten or replace |

Manual Diagnosis: Thermocouple failure or dirty pilot orifice.
Fix: The manual provides part number SP20058 for the thermocouple. It instructs you to clean the pilot tube with compressed air or sandcloth.
