OK, rather than starting yet another thread on a very specific topic, which would probably die out after a couple of replies, I thought I'd start something more generic. We have lots of members with a lot of experience in all different areas, and many (most?) are homeowners who have probably faced the issue you may be having now. So, ask away. I'll start.
A few days ago, the first day of exams for my oldest, of course, we woke up to find no hot water. None at all. I've had an issue with my temperature regulator switch in the past where it didn't "trigger" if there wasn't enough volume of water going through -- basically, the hot water would run cold until I opened another tap or ran the shower or whatnot; the best one to "fix" this issue was the soaker tub in the main ensuite, as it would produce the bet flow. However this time even that didn't help. Eventually I went to the basement and saw that the diagnostic light at the bottom of the water tank (a small unit where the gas line attached) was flashing red. I read the stick-on instructions which said that, if it was solid red, to shut off the gas and call someone, but if it was just flashing red, to "follow the instructions". Looking around, the only instructions I saw were the startup ones. So I followed them to turn off the power (unplug the cord), turn the gas off and the temperature know to lowest setting, then turn the power back on, turn the gas switch on, then finally turn the temperature switch to the desired position. The burner started up again, I didn't blow anything up, and a little while later we had some warm water (too late for my son, but his exams went fine, regardless of his appearance).
So the questions I have:
- What could have caused this? We had really, really cold weather for a few days in a row leading to this. Could that be somehow related?
- Should I call someone to check it out? The hot water tank is a rental unit. The "instructions" did not say anything about any follow up.
