How to troubleshoot a Rheem Model 82V52-1 Electric Water Heater

Hello - I suddenly loss hot water. Tested voltage across top leads to thermostat, 0V. Tested each lead to ground, 120v. Shouldn't I be seeing 240v across those leads? Does this mean that the thermostat is defective?

Press reset button located on upper thermostat. Test elements with multimeter set to read ohms, or replace both elements. And then replace both thermostats.

If you don't have current, 0v from terminal to terminal, then you don't have voltage to the elements. Replace the thermostat but check that you have 220v to the thermostat. It is possible that your breakers to the unit are either bad or tripped.

SOURCE: I can't get 240v across the bottom element. Where

If that is indeed so you have a "Short" between Phase and Earth. .. YES one should have the mains Voltage across the Load, But NEVER anything between Phase & Earth. Look think of it all like this. The Phase comes in, to a, say, a switch, from switch, to thermostat, from thermostat, to One Side of the "Load" Element. The "Other side of that "Load" Element then goes to Neutral. Circuit Complete. Two elements, wired in series would indeed split the Voltage, if wired that way. If done like this, but if wired in parallel, then, again Both would have One End, connected to Phase, & the "Other" side(s) would go to Neutral. Thus the circuit is complete. Some setups are more complex, and use two elements. but essentially all the same. The elements could be wired in series or parallel, depending on current draw/resistance. The Phase is the wire always "Broken" and the Neutral is always "Common".
BE CAREFUL.

Check the relief valve,drain and element's,water lines to make sure that they are not the source of the leak. If the tank is leaking you may be able to fix it for now.

The tank depending on condition of the tank if it is pretty sound. Clean up the area of the hole with sand paper. Go to any hardware store and get a JB Weld two part kit. JB Weld will fix almost anything . You can go to www.jbweldit.com for more information about this product. I wish you well and hope this will fix it for you.

Be sure to have your circuit breaker off before you remove the cover.
220V and water together is not a good mix.

SOURCE: installed new rheem 40 gal

did you turn the power on BEFORE you filled it with water???

this is a pretty common mistake. you will need to check the upper element to make sure its working.
most water heaters have an upper and lower themostat. the upper thermostat is the one we need to check.

use your volt meter...

turn the power off, test with your volt meter to make sure! remove one wire from the element, not the thermostat, and check resistance on the element. if no resistance, you burned the element, and will need to replace it.
replace with same wattage, usually 4500watts. it will be written on the element.
also, I like to push the reset button on the thermostat to make sure it wasn't tripped.

Hot water heater


1) Check across top two screws on upper element for 240volts.
Circuit breaker can be tripped on one leg so water heater appears to have power, but only has 120Volts to ground, and not full 240Volt potential across both wires.

I just installed a marathon 50 gallon 4500 watt, hot water heater. I do not have hot water. The wiring to the upper element and thermostat all test at 240 volts. The lower element and thermostat show no...


The top element should be heating if there is 240 volts across the element terminals. I take it that the top element is the booster element. The thermostat for the top element is normally a 2 pole thermostat which switches the neutral to the bottom thermostat once it reaches temperature. Once this occurs then the bottom element will start to heat. The top element will only come on when you use all the hot water. Is this supply on the off-peak rate? When testing always check the voltage across the element terminals.

No hot water


You posted under Rheem 40 gallon electric water heater, which is two-element 240Volt heater.
If this is not your heater, add a comment.

If you suddenly have no hot water, that narrows the suspect list.

Step1:
Check for tripped circuit breaker.
Open top cover on water heater and push in reset button on upper thermostat.
If reset button is tripped out, and will not push back in, then replace upper thermostat.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
Put ear against tank and listen for bubbly-fizzing sound that says heater is ON.
If reset is not tripped, then move to step 2

Step 2: use tester or multi-meter and test across top two screws on upper thermostat for 240Volt.
If heater is not getting 240V, then test circuit breaker.
Move water heater wires from 240V breaker to another same-amp 240V breaker and see if that restores power.
You may need to replace breaker:
http://waterheatertimer.org/How-to-replace-circuit-breaker.html
If problem persists, then you might have a line problem between breaker and water heater.
Open cover on top of heater, and check connections on top of heater.

Step 3:
If heater is getting 240V, then upper thermostat or upper element is bad.
I suggest 30 minute troubleshooting which could save you a service call, and will be valuable information in the future:

Rheem warrior glass serial num-rh1098154699 model num-71-40d b That is all the information i collected off my hot water heater we have no hot water at all and i dont know how to fix this problem...


The label would also say if water heater is gas of electric.
That would be helpful information that could lead to troubleshooting.
Serial number tells us water heater was made on Nov 1998, which tells us the manual will not be on the Rheem website.

So if you have electric water heater, and no hot water.
There can be 4 causes.
1) Circuit breaker is not delivering 240 to water heater. Test top two screws on upper thermostat to see if tank has 240V.
2) ECO red reset button is tripped. Open top cover on tank and push reset button.
3) Upper thermostat is bad. Replace thermostat.

My water is not heating in my Rheem 40 gallon electric. I pushed the reset button, but when I turn off the breaker and then on again, I do not hear the elements heating up.


Electric water heater can be repaired by homeowner
If I understand correctly, water heater is producing no hot water.
Reset button clicks in, but still no heat.

Three initial things can be causing this:
1) No power to water heater. Test across top two screws on upper thermostat for 240V. Red and black wire are attached to these screws. Screws are marked 1 and 3. Upper thermostat is same that has reset button. If power tests 120 across screws, then breaker may be off on one leg. If no power, then start testing at breaker.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

2) Upper thermostat is bad. Replace thermostat with generic upper thermostat available at hardware store.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

3) Upper element is bad. Test and replace element using Rheem 4500 watt element available at hardware store. Image shown below. Look at label on side of tank for element wattage. Rheem puts 4500 watt elements into all their 240V electric water heaters.
http://waterheatertimer.org/How-to-test-water-heater-element.html

If upper element is burned out the tank will not heat any water.

I have a model 71-408 B which just stop heating


If I understand correctly, you have electric water heater.
Heater suddenly stopped heating.

Four things cause sudden loss of water heater.
1) Reset button located under the top cover is tripped > turn off power, remove cover, press reset button > if reset keeps tripping, go to the troubleshooting link shown below.
2) Electric power to heater is interrupted > check circuit breaker > test for voltage > look for loose wire on breaker
3) Upper element burned out > test and replace element
4) Upper thermostat bad > replace upper thermostat

Reset button is best suspect.

Installed new upper & lower elements & thermostats, only top htr works


If original problem was caused by sediment burning out lower element, did you clean sediment out of water heater when changing lower element?
Two element water heaters are 240V.
Thermostats cut power on one hot wire, but 240V circuit has 2 hot wires. So lower element has power at all times coming from the red wire.
1) Use ordinary tester or multimeter set to 240V <> test each screw of lower element to bare metal part of water heater. Each screw should show 120V. If there is no power, then upper thermostat is defective, screw on upper thermostat is loose, or red wire between upper and lower parts of water heater is bad.
2) Remove wires from lower element. Use continuity tester or multimeter set to ohms <> test across both screws of element to see if power travels through element <> if element is bad, then continuity tester will not light up and multimeter will show no ohms. Put wires back on element after test.
3) Start with cold water in tank. Turn on water heater & upper element will turn on. Put ear on side of tank to hear if upper element is heating water. Test #3 screw to #2 screw on low left side of thermostat, should read 240V > Test #3 screw to #4 screw on low right side of thermostat, should read 0V.
Put ear on side of tank. When upper element turns off: Test #3 screw to #2 screw on low left side of thermostat, should read 0V > Test #3 screw to #4 screw on low right side of thermostat, should read 240V. If this test shows 0V and 0V, then upper thermostat is bad. If reading is correct, immediately move to next test.
http://waterheatertimer.org/images/Thermostats-numbered-divided-500.jpg
4) Turn temp on lower thermostat to 150. Using ordinary tester or multimeter set to 240V <> Test across both screws of lower element. If there is no reading, and you know element is good from step 2, then lower thermostat is bad, or wire is bad between lower element and lower thermostat, or wire is bad between lower thermostat and top part of heater.
5) Test across both lower thermostat screws, should read 240V.If this test is good, it means wires are good. Put jumper wire across both screws of lower thermostat, and test lower element again. If element finally turns on with jumper wire, then lower thermostat is bad.

If wire is bad between upper and lower parts of water heater, and water heater has tight-fitting 2" foam insulation, it usually indicates water heater replacement.
