Customer stated that water heater wasn’t heating water properly. Also, customer stated that gas burner assembly and also gas control valve was just replaced. I first noticed that TMP line is not up to code and not properly ran and also that water heater is backdrafting at times due to melted plastic on top. At this time status light on gas control valve is working fine and also there was a flame at the bottom of the heater. Put gas control valve to pilot in status light turned red. Found that error code was throwing for is a flame sensor. Attempted to get gas control valve to throw the same code, but wouldn’t do it again. Stated to customer that there may be multiple issues going on with water heater for example one could be dip tube, cross connection, and etc. Customer also stated that water heater is still under warranty through Home Depot and recommended customer to go get new water heater from Home Depot. Will send customer estimate for repairs needed and also diagnostics for water
