We replaced our hot water heater with a new 50 gallon AO Smith unit in Nov 2022. In Oct 2025, the unit stopped heating and throwing an error code to replace the control valve. The plumber who installed the unit came out and it took 10 days to get it fixed. The problem was with AO Smith warranty policies making it extremely difficult to remedy. We had to try three different parts (one at a time I must add) and I incurred over time charges because of weekend work and after hours. Fast forward 3 months and the same issue has occurred. And, unfortunately, AO Smith is making us go through the exact same process, including replacing the control valve…again. I have called customer service multiple times and been on hold for lengthy periods of time, only to have customer service say it’s their policy “to troubleshoot the issue” and they won’t just replace the tank. So we sit at least another 4 days without hot water. I would never buy another one of their products and if I could give less than a 1-star rating, I would.
