Hello I'm about to donate my hot water heater to mythbusters to blow up. but its not even any good for that since it doesn't work. I checked the thermostat and elements and everything seems to be working fine but its just not heating the water. I am showing 240V at both elements. I tested the elements with a continuity tester both were fine the top element is only about a month old. I took out the bottom element and there was some build up between the rods but i cleaned that out. I had a frozen pipe that burst on the outlet side of the hot water heater. It was in crawl space and did not realize it for about a day. I thought i solved the problem why the water was not getting hot, it was all leaking out. but i fixed the leak and still no hot water.. I dont know what else to check.. The heater is only a couple years ago and i hope i dont have to replace it.. Any suggestions?
