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.

I have a Rheem 81SV-40D water heater, water is hotter in the morning and only warm at night. I don't see a time or anything. Can you please help me to figure out what's wrong? thanks


Dear Chu,
I think I am hearing you say the water is hotter if the water heater has sat all night without the usage of any hot water, and otherwise, it is not hot.
I should suspect one of your heating elements is not good any more.
Look and see if there are 2 removable covers on the side of the water heater, an upper and a lower.
Take a test instrument and, with the water heater unhooked from the power source, see if you have one element that shows no continuity with an ohm meter /resistance test.
That element can be replaced, sometimes you must drain the water heater water to do so.
God bless your efforts.

I switched off the power prior to looking at this, i did not wire it. landlord replaced thermostat yesterday after the heating element had already been replaced2xs now, 0 hot. heater model 71-40sb


Is this a 220 VAC H/W Heater or a 120 VAC H/W Heater?
Note: Info provided here is for a 220VAC H/W Heater
Thermostat doesn't look like a new one, maybe it is used!
Check input power (voltage) on top two wires if this is a 220VAC H/W Heater ... then the input power from the C/B in the Electrical Panel should be 220 VAC. If 220 VAC power is not present on the top two wires ... you may have a bad C/B in Electrical panel. Make sure C/B is turned ON and if still no power on top two wires replace C/B. If 220 VAC is present on top two wires then press Red Reset Button very hard to make sure it is Reset. Then check for 220 VAC at the Thermostat ( bottom two terminals), if 220 VAC is present then check for 220 VAC on the Heating Element terminals (bottom of picture). If 220 VAC is present on the terminals of Heating Element then H/W Heater should be working otherwise Heating Element is Bad and replacement is necessary. Good Luck! Handy Henry

In-home Hot water heater; I've changed elements, both thermostats, and the electronic circuit on my circuit breaker. Is there any other reason why it is not heating up my water?


Use a test meter between elements to see if your getting continuity
and between power lead before elements. There has to be a line break if your not getting power entering elements.

Water Heater Issues


An electric water heater contains two elements (usually upper and lower). Normally hot water is maintained at a certain temperature to assure an immediate supply. When hot water is turned on at the fixture, the second element is turned on to boost the temperature. From your description one of the heating elements may be defective or set to incorrect temperature.

The controls of electric water heaters are designed so that at no time are both the top and bottom heating elements energized. Nearly all electric water heaters of this capacity in the US & Canada (other places, too) operate on 240 Volts.

When the water in the tank is below the set point of the thermostat (in your case - 120 degrees), the top heating element is expected to be on - (unless there is an issue with the top thermostat or limit switch). The top most control is the "high temperature limit". It is identified by the reset button on it. Make sure this isn't tripped by depressing the button. If it clicks - it was tripped and should start to make hot water at this point. If not tripped, you should check for the presence of 240 Volts between the heating element terminal screws. Do not measure from ground to a terminal screw and believe 120 Volts is "good". To make heat, you need 240 Volts - not 120 Volts measured across the terminals - not to ground. The amount of heat created running at 120 Volts is only 1/4 of what it will do at the correct voltage.

If you don't measure 240 Volts on the top element, check the bottom element in the same manner described for the top element.

If unable to measure 240 volts on any element, either there is a problem with the power source (blown fuse or circuit breaker), high temp limit switch, or thermostat(s).

If 240 Volts is present on either heating element, and water is not warm / hot in 30 minutes or so, a defective heating element is suspect. You can change controls without draining a tank, but replacing elements will require draining the tank first. Do not power the water heater without first filling it.

You can read a very detailed "how to" article about checking water heaters here.

I hope this helps - and good luck!

Hot water does not last long. Model 82vh40-2 mnf. 05/2005


If the lower heating element burns out the upper element will heat the top part of the tank then shutoff. homw depot/lowes etc should carry elements. 1 turn off breaker, remove element access cover (the 2 panels on the front of the heater) test for electricity at the reset button ( uppermost device in upper panel) to make sure power is off. 2 turn off water (I usually turn off the cold water main to stop water cross feeding into hot supply line back into heater) 3 disconnect the 2 wires on the lower element, test with continuity tester. shhould be no continuity between terminals and tank, but around 10 ohms between the 2 terminals. Check the thermostat for continuity if tank is cold thermostat should be closed ie zero ohms across the 2 terminals.
If stat is bad replace stat; disconnect wires push it up out of the spring clip insert new stat reconnect. If element is bad: drain tank. connect garden hose to tank drain valve, open tank drain valve turn water main on to clear rust sediment and get water flowing. Next remove filter screen from a hot water faucet then turn on ( a hot faucet upstairs or higher than tank drain). Now turn water main off, air will now go in through hot faucet and tank will drain, takes about an hour. Use a water heater element wrench about$10 to remove element(s) make sure no bits of rubber gasket are left in element opening- dig em out with a screwdriver if needed. Insert new element with its gasket and tighten. reconnect wires DO NOT TURN ON ELECTRICITY! BE SURE TO FILL WATER HEATER WITH WATER ! Turn water main back on -air will come out of the hot faucet for several minutes. When water runs without any air sputtering, turn off faucet and replace the faucet filter screen. check element(s) for leaks. turn breaker back on.

The water is not heating


Check for power at hot water tank. Check the elements for continuity. You may have to replace your elements on you hot water tank

The water gets too hot and trips the reset on the thermostat.


Two possibilities. 1 failed upper or lower Tstat 2 Shorted element
To test element: disconnect both wires to element terminals. use continuity tester to see if there is continuity through element (one probe on each element terminal) If no continuity element is bad. Then test for continuity between each element terminal and the water heater itself.( one probe on element terminal and one probe grounded on bare metal or inner tank.) If there is continuity from terminal to ground, element is bad and also can cause tank to continue heating even when thermostat shuts off. This is because the thermostat only shuts off one pole of the 220 and a shorted element can continue heating from the 2nd pole.
If both elements test OK and water heater heats the full tank( tank feels hot at bottom element access panel when no hot water for 2 hours) most likely the lower thermostat is bad.
