During our visit, the customer mentioned they did not have any hot water. Upon inspection I mentioned that we would need to troubleshoot the unit to figure out what’s going on. An estimate was approved for a troubleshoot to be completed. After removing the top cover on the water heater, I pushed the reset button and heard a click. This indicated that the thermostat was tripped due to the water heater over heating. I spoke with AO Smith on the phone and able to order the elements and both the upper and lower thermostats. The water heater is currently working and the new parts should be here 3/4. The parts are being delivered to the customers house and they plan to call when they arrive.
