By mistake I turned the power on to my water heater before the tank was full of
water and burned the upper element. I thought the lower element would provide heat, but obviously at a lower rate. I found no power at the element. It appears from the limited wiring diagram I have, that the upper thermostat switch provides power to the upper element until it reaches the set temperature, then provides power to the lower thermostat and element. Is that correct? I needed to wire the lower thermostat to the upper element to get heat last night until stores opened today and I could get a replacement. I thought both elements were powered at once, but appears that is not the case. The heater has what the supplier calls typical 2 element wiring. My questions are 1) are indeed the elements powered as I described or am I missing something?, and 2) is there a suggested temp. setting for the elements if that is true, i.e. should the lower element be set at a higher temp then the upper? Thanks in advance. |

I'm sure the OP was going to. He was relating his experience in trying to jerry-rig the thing for overnight, at least, so that he could have _some_ hot water until such time as he tore it all down. He was just trying to make sense of what he encountered. Jonesy -- | Marvin L Jones | jonz | W3DHJ | OS/2 | Gunnison, Colorado | @ | Jonesy | linux __ | 7,703' -- 2,345m | config.com | DM68mn SK |

Thank you very much for the answer. I just retruned from a trip that took 37
hours of flight time and didn't feel up to a total repair that night. I always intended to replace the element, but was trying to figure out if I needed anything else. The curious thing is when I replaced the upper element and returned the wiring to the original configuration, the lower element did get powered. So I'm still a little confused by the wiring diagram as I don't see how the lower element would only get powered if the upper elemnet is OK. The bottom line is I jury rigged it for us to get showers that night, replaced the element the next day and all is well. One question, why did some people assume I was trying to be cheap and not replace the element when all I was trying to do was get an explanation of my observation that confused me? |

The lower element won't get power if the upper element is dead because the upper water will never get warm enough to trip the thermostat to turn off the upper element and turn on the lower one. People assume that people are trying to be cheap because quite a lot of those who post here are. You wouldn't believe some of the stuff that gets asked. |
