Woke up to no hot water changed out both heating elements and both thermostats meter says wiers are hot checked breaker its got power still no hot water any suggestions


Water heater can test for power, but is only receiving 120V instead of 240V.
Test that upper thermostat is getting 240V across top two screws of thermostat.

No hot water power is on and is present at thermonstat. heating elements show continuity


Sounds like water heater is getting 120V but not 240V

You say there is no hot water inside the tank?
You have two elements, so tank is 240V.
Both elements test for continuity.

These three symptoms together imply that water is getting 120Volts instead of 240Volts.
Water heater appears to have electricity, but is receiving power from only one leg of the 240Volt circuit.

New water heater will not heat


Water heater has to be full of water before power is turned on or elements will burn out.
If upper element is burned out, then no hot water.
Lower element burned out, not much hot water.
If tank has 2 elements, it is 240V. Water heater circuit may not be delivering 240V. Test for 240V at connections.

Lost water to the heater. When got water back, got rust from faucets, and then no hot water. Test both elements, got juice to it


Water heater with 2 elements is 240V.
Tester can show electricity at the water heater with 120V, but unless upper element is receiving 240V, then the heating cycle will not start.

Hi,
The unit will not owrk unless you have 240V ACROSS the black and white wires...if you do not have that coming to the unit then you have a bad breaker...

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:

I have replaced the bottom element,and now i have no hot water. I check with a meter and have power to the top element but not the bottom one.


First of all, you have 240V water heater because tank has two elements.
You have no hot water, and tank has power to upper element.
Lower element has no power.

Something doesn't sound right.
You're not testing correctly.

Before doing anything, test across top two screws of upper element for 240Volts.
This will eliminate electrical problem as suspect.
Breaker must deliver 120V on both legs to complete the 240V circuit.
Every single-phase household circuit takes 2 wires to complete the circuit.
With 120V you need 1 neutral wire and 1 hot wire to complete circuit.
With 240V you need 2 hot wires, one from each hot busbar, to complete circuit.
Your water heater can appear to have electricity if breaker is delivering power on one leg of the 240V circuit.
To check breaker for sure, move wires to another similar size breaker to see if water heater functions properly.
http://waterheatertimer.org/B220C.html

If 240V circuit is good, then next thing is take 30 minutes and do full test of water heater parts.
This will identify exact problem(s) without guessing.
Buy 5$ multimeter from Home Depot. Install battery.
When test calls for continuity, rotate dial to Ohms (upside down horseshoe is ohms).
When test calls for testing voltage, rotate dial to 240-250-277 VAC

No hot or warm water what is the voltage reading susposed to be on the heating elements? I have 122 volts on each terminal on both elements but no action, what am i doing wrong?


If water is totally cold, then upper element is not getting 240V. Since element tested for 120V, then that says upper element is burned out, upper thermostat is bad, or circuit breaker is bad.
Best thing is to buy multimeter and do 30 minute troubleshoot:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Also read information below for understanding how water heater works.

Testing elements for voltage can be misleading.
If water heater has 2 elements, then tank is 240Volts.
240V water heaters have 120V on each element at all times.
So elements have hot 120V power, but they are not turned on until the circuit is complete with 240V.
Open following links to read specifics about 120V and 240V
http://waterheatertimer.org/B220C.html
http://waterheatertimer.org/How-water-heater-thermostat-works.html

240V is made from two 120V Hot wires from breaker box.
Each 120V line from breaker is called a 'leg.'
So 240V circuit has two legs, and both legs need to be turned on to complete 240V circuit.

Water heater thermostats turn off only one leg.
The other leg is Hot all the time.
So when you test screws on an element, for example test between a screw and any bare metal part of tank, then the screw will always show 120V.
That is just one leg of the 240V circuit.
But the 240V circuit is not turned On until both legs are connected.
Every residential circuit needs two wires to complete the circuit, and in the case of 240V, those two wires are both 120V.

When the thermostat turns on, it turns on the second leg to the element and that completes the 240V circuit.
