I was tasked with diagnosing a problem with a Rheem water heater. I started by checking the power supply and circuit breaker to ensure they were working properly. Then, I inspected the thermostat and burner assembly for any signs of damage or wear. After that, I tested the temperature and pressure relief valve to make sure they were functioning correctly. Finally, I checked the gas valve and combustion air intake for any obstructions or leaks.
