A few months ago I replaced both heating elements in our electric water heater. I checked the dip tube at the same time, and it was OK. (Thanks to the people here who helped.)
Now for the last couple of weeks sometimes there is plenty of hot water for bath/shower and sometimes not. There either is or isn't - with not much in between. This is NOT right after using hot water for washing dishes or clothes.
I have a volt/ohm/amp meter, but I don't know how to test these A/C things. How can I (with only a little experience) test the water heater elements and thermostat?
Thanks in advance.
