For this job, we came out to diagnose the water heater and found it displaying an evaporator temperature sensor failure, along with difficulty maintaining the set temperature. Based on our evaluation, we determined the issue was likely caused by a failing sensor. The customer chose to contact Rheem directly to obtain the necessary replacement parts for their 40-gallon unit, manufactured in June 2023. We also provided estimates for installing a mixing valve and repiping the water heater with proper 3/4” hard piping, as the unit is currently piped entirely in PEX. We will prepare estimates for repairing the sensor issue once the customer receives the appropriate parts.
