Check the thermastat, located in removable panel. warning dont set above 120- 130. If not the case it could be a bad heating coil. Easy to change in electric just googl a how to sitr. If your not Real Handy with Your Handa I would recomend calling a plumber to check heating element, Could be cheaper to replace

I have water in the junction box on top of my hot water heater and into the electrical conduit leading to the hot water heater.


I do not see your earlier post with photo.

The problem could be the conduit.....
-disconnect the conduit and wires from water heater
-run wire into a junction box set lower than top of water heater... -then run another #10 wire from the junction box up to water heater...
-So if water is coming from conduit, it will accumulate into junction box and not in the water heater wiring cavity.

Next thing....
... a water softener can cause rusted tank.
-Softened water adversely affects anode rod...
-causing anode rod to deplete faster...
-once anode rod is gone, then tank begins to rust.
-Here are details for checking anode rod each 2-3 years:

Rheem electric water heater 50 gallon, lukewarm water. Water is warm but not hot, where should we look for problem?


Luke warm water is the result of top element bad and the bottom is the only one heater. The best solution I can reccomend is to change both out due to the fact the bottom element may go bad and since you have to change one you might as well change both.

Turn power and water off, drain heater down and once water is drained out change them out. Once new ones installed turn water on to fill heater and open faucets and get air out on the hot side of each faucet once water is flowing out of each faucet you are now ready to turn power back on.

I am only receiving half of the normal amount of hot water.


You have electric water heater.
Electric water heaters are fully repairable by homeowner, excluding hybrid type.

Rheem electric water heaters:
http://www.rheem.com/products/tank_water_heaters/electric_water_heaters/
Rheem fury series manuals and models
http://www.rheem.com/product.aspx?id=09DF2BDD-5E11-4D32-B574-84ACFB8A4619

Age of Rheem water heater is shown first 4 digits of serial number located on side of tank: for example 0705 means July 2005.
Serial number also shows model number & wattage of elements in case you need to buy new generic 4-bolt type 4500 Watt element from hardware store.

A) If your water heater receives very cold incoming water, it may not heat fast enough to keep tank warm.
Add a tempering tank.
http://waterheatertimer.org/Tempering-tank.html
Add insulation over entire water heater except TP valve. Insulate pipes completely.
Read more information:
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html

B) 40 or 50 gallon water heater is 240Volts and tank will have 2 access panels on front.
Rheem ships all water heaters with 4500 Watt elements.

Narrow down the suspects:
C) Water heater has some hot water.
This tells us upper element is working.
And that water heater electricity is working.
And that reset button is not tripped.
And that heater is not experiencing run-away overheating event.

That gives us 3 solid suspects.
1) lower element is burned out. Test lower element using inexpensive multi-meter from Home Depot.
http://waterheatertimer.org/How-to-test-water-heater-element.html
Replace element with same wattage shown on label, and clean out sediment:
This will restore water heater to full 99% efficiency.
http://waterheatertimer.org/How-to-clean-sediment-out-of-electric-water-heater.html
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

2) Upper or lower thermostat is bad. Replace both thermostats for about $25.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
If you want to test thermostats and all parts before replacing anything:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

3) Burned or shorted wire. Turn off power. Open covers on side of tank. Remove insulation. Inspect parts for signs of high heat and burning. Especially lower element. Tighten any loose wires. Replace part that shows signs of burning.
Put insulation and cover back over thermostats so cooler outside temperature doesn't cause thermostat to misread tank temperature.

Top heating element was broke. Replaced got hot water for week. Now have to run hot water for 20 mins before it goes from warm to hot. Top heating element reads 240VAC bottom heating element reads...


look for a badly connected power line ont he bottom element, or any connection upstream of the power terminals. voltage readings usually drop to that range when you only have one side of the 220v circuit connected.
