Question about Element Chromalox SG1353-430326 Electric Replacement Water Heater
The heater is giving less hot water than before-hot water runns out quicker. it has a 4100-59T on top and a 4000-59T on the bottom. i get eletrical continuity through the whole serquit. How can i tell if it is the element or the therm-o-disc that is bad or ?
Disconnect the electric for the unit. Disconnect the two wires from the two eliments. Place a battery type test light or Ohm meter is more conclusive if you have one, Light should light when placing the two test leads to the two eliment contacts(while they are disconnect for the water heater wiring) should be dim but glowing. If no light the the eliment is open. If an Ohm meter the Wattage is written on the heater the heater. E=IR P=IE. It should work out to about 1200 -1400 ohms if 220 volt heater. If the light is bright just as if you had put the two test leads together,then you can say that the eliment is likely shorted. Either no light or a Very bright light requires the eliment to be changed. To check the thermostats, Raise the ajustment one one at a time, until it clicks. Listen for the heater to be heating. Turn that one back down and do the other one the same way. I hope I have been clear enough. About one gallon of water should be drained for the bottom of the tank once a year along with checking the preasure/tempature safety relief valve by operating it ,using the leaver,for a few moments as preventive maintenance.

The element will start to leak if it breaks sometimes so you can tell that way. The other way it might not be heating properly is if there is to much calcium build up on the element itself.
The way to check the thermo is to check for continuity. If it is closed then it is good. Open it is bad This is of course wit the power off
