Noticed the hot water getting cold sooner than normal  recently.Figured it had to be a faulty thermostat or a burned out element.

To solve the problem of which is at fault I purchased a water heater tune up kit [$35.00].   The kit included 2 4, 500-Watt, 240-Volt water heater HWD screw-in elements, 1 Therm-O-Disk 240-Volt lower thermostats and 1 Therm-O-Disc upper thermostat.  Also an element removal tool [$8.00]

Yesterday I shut off the water heater breaker, Ran the hot water at the sink until turning cold, drained the water from the tank, Charted the wiring schematic, removed and replaced the upper and lower elements, removed old thermostats, replaced with new thermostas rewiring according to the wiring schematic, turned on the cold water line to the tank filling tank to pressuried level after closing the hot water faucet at the sink, Checked the elements for any leaks at the threaded connection for leaks, no leaks, replaced the platic shield over thermostats and elements. replaced insulation, put access covers back on.

Turned breaker back on. Did not see the breaker trip or smoke coming from the tank. Left the breaker on and waited for the water to heat up to thermostat setting temperature [120 degrees] . After I figured it had time to heat up to temperature I turned on the hot water at the faucet and checked the water temperature with a probe type temperature gauge [ topped off at 120 dgrees].

Been 24 hours since fixing and all looks OoKa.

Al least I will not need to finish my shower in cold ass water.
