The Tank › Power Shot (A.O. Smith) doesn't switch on automatically

My gas water heater switches off before the water has been properly heated to temperature and/or doesn’t automatically switch on when it should (like after a shower and running the dishwasher). It’s about 9 years old, 50 gallon.
What I have been doing is manually switching off the power vent and then switching it back on. For some reason, this kicks the thing into gear and it begins heating.
However, sometimes it turns itself back off before the water is to temperature. If I toggle the power vent switch on/off over the course of, say, an hour, then the water is good to go. When the water is hot and I toggle the power vent off and on, it doesn’t come on. Which makes sense.
…but to add to the confusion, sometimes I don’t have to do anything and it comes on on its own and heats the water properly.
Any ideas?May 20, 2017 at 9:30 am #23718Larry WeingartenParticipant
Hi, Under “tanklets” have a look at “power vent issues” and see if something there helps. Flame sense rod, pressure sensor and drafting problems come to mind.
