    The hot water heater had been going out for days. After a shower I smelled burning and the electrical panel in house was hot. Turned off breaker to hot water heater, replaced both elements and thermostats, turned breaker back on. When you start using hot water the smell and hotness to electric box in house happens. Turn off breaker to hot water, no problem with electric box. Bad hot water heater, bad breaker, don't know.

Symptom: water gets too hot, before and after thermostats are replaced, burn mark and insulation swelling/melting on non-common wire from upper element to upper thermostat, and the breaker trips.


Double check the thermostat connection and setting; if it persists, I would add a pipe hugging thermostat connected to a shunt trip for the heater elements.

Hot water intermitten and also burning smell coming from Intermatic T103 Timer


Jan 2013. Yes very experienced. Multiple issues. Bad thermostat. Burned contacts on timer.
Let's break it down.

1) Water heater tripped:
29th the electric water heater reset button was tripped because ECO detected high heat from very-hot-water, or nearby burned wire, or loose wire, or bad thermostat.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

2) Description of water heater:
40 gallon Rudd (Rheem), 2 thermostats and 2 elements indicates ordinary 240Volt water heater.
More information shows on label on side of tank, including valtage rating (208-240), and element wattage (usually 4500 watts).
Rheem-Ruud serial number, 3rd and 4th digit are year of manufacture.

3) Solution for water heater:
Tripping ECO reset button, Very hot water, and sometimes not-so-very-hot ... sounds like bad thermostat, and/or bad element. Replace both thermostats, and see if problem persists. Then replace elements if needed.

4) Information about timer:
Water heater circuit has 40 amp T103-Timer, which is plenty heavy for ordinary 240Volt household water heater that draws 19-22 amps.
T103 timer has repair parts, and can usually be repaired unless overheated contacts caused melting, but that can also be worked around in some circumstances, or the internal mechanism replaced by buying T103M mechanism-only and snapping into existing box.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T103
http://waterheatertimer.org/How-to-troubleshoot-Intermatic-timers.html

5) Solution for timer:
Attach photo of inside of T103 timer, and I can assess what steps will most likely fix the timer.
Maybe the timer is not connected to water heater.

Tough problem here. Most dual element heaters share one line. if this is the case and you have power on the top and none on the bottom I would check the connecting wires one to another. also check the settings of the thermostats. They may be adjusted all the way down. If the wires and connections are good I would recommend ohm testing the new elements. I have burned elements out by introducing cold water to very hot coils (forgetting to turn the water on after flipping the breaker)
Never forget that calcium buildup will short the element. If touching on the bottom you will burn it up.
If this does not help try borrowing hot water from neighbors ;)
Good luck

I replaced all parts but water heated won't get hot


You have electric water heater.
You replaced elements and thermostats but heater still won't work.
And tank was completely full of water, and water was running out of a faucet before turning power ON.
If elements are not fully immersed in water, they will instantly burn out.
If upper element is burned out, then tank will have NO hot water.
If lower element is burned out, and upper element is not burned out, then tank will have some hot water.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-it-works.html

If elements did not burn out, then that leaves 1 main suspect: the electricity.

1) Push in ECO red reset button on upper thermostat. If ECO is tripped out, then heater will not work.

2) Click circuit breaker all the way one direction and then back the other direction to make sure breaker is latched.

3) If tank has 2 elements, then it is 240volt.
If 1 leg of 240Volt circuit is not working, then 240V appliance will not work.
240Volt circuit needs both hot wires to complete the circuit:
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html#120-240

Buy cheap multimeter from Home Center and set dial to 240-250-277VAC
Tape tester leads to woods sticks to keep hands away from power.
Power is ON
Test across top 2 screws on upper element should show 220-240 volts.
If you have 240 at top two screws, then skip down to step 6.
If no reading across top two screws, then move to top of tank.

4) Open connection point where wire connects to heater.
Test across both insulated wires should get reading of 220-240 volts.
If no reading, move to circuit breaker box.

5) Mark water heater breaker.
Turn off all breakers except water heater breaker and main breaker. (and breaker to light fixture where box is located)
Do not hold or touch or lean against anything metal.
Stand on dry boards and wear dry clothes.
If main breaker is OFF, the big wires that connect to main breaker are still HOT.

Remove box cover.
240Volt breaker has 2 wires connected with screws.
Test across both screws for 240Volt.
See if wires are loose.
If there is no reading, then breaker is not working on one leg.
To double check, move water heater wires to another same-size 240V breaker and then put ear against water heater to listen for bubbly-fizzing sound.

6) If you are getting 240 to water heater, then wire inside tank could be loose.

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.

Replaced both lower and top elements and upper thermostat still no hot water. proper elec. going to unit.what could it be?


You need to take 1/2 hour to learn basics and then test water heater parts before replacing anything.
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html
Follow the troubleshooting steps, and it will tell you exactly where the problem is.
Otherwise we can guess at 20 different things.

Water heater is 240V because you have more than 1 element.
Did you test for 240V across top two screws of upper element?
Breaker can be tripped off on one leg and 120V arrives at water heater so heater looks like it has electricity, but circuit is not complete.

The problem can be loose wire, bad 240V circuit breaker, sediment reaching lower element, bad thermostat, bad upper element, tripped ECO reset button.

Did you replace factory insulation and cover over thermostats after replacing elements?
Did you vacuum out sediment when replacing lower element?

How long ago did you replace elements? If you turned power ON before tank was completely filled with water, then you burned out the element. If upper element is burned out, the tank has no hot water, even if lower element is good.
Test the upper element:
http://waterheatertimer.org/How-to-test-water-heater-element.html
See how a water heater works:
http://waterheatertimer.org/How-it-works.html

And finally, why so many folks write to fixya saying they replaced both elements and upper thermostat, but they never replace lower thermostat for another $6? I have been puzzled about that since lower thermostat turns on and off each time tank temperature drops and is responsible for keeping water warm during standby hours. Lower thermostat cycles more times than upper thermostat.

Add a comment if you need specific assistance with any of the testing steps.

No hot water


Electric water heater can be repaired by homeowner.

Four things can cause NO hot water:
1) ECO red reset button tripped. Remove top cover on water heater, push red reset button on thermostat. Put insulation and cover back over thermostat.
2) Circuit breaker is tripped, circuit breaker bad, or wire loose in breaker box. Turn breaker on-off and listen for crackling or fizzing sound, and burned smell. Test breaker for 220Volts. Test top two screws on upper thermostat to see if water heater has electricity.
3) Bad upper thermostat. Replace upper thermostat.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
4) Bad upper element. Test upper element.

OUR WATER HEATER IS BLOWING FUSES ..


1) Turn off power before touching water heater that is shorting or wet or was flooded.
2) Circuit breakers & fuses blow because of heat. A short will cause heat. Tighten screws on terminals inside box, listen for crackling sound/burning smell from loose-fitting parts.
3) Easy test for circuit breakers: move water heater wires to another same-size breaker. If same-size does not blow, then problem is breaker.
4) A short between fuse box and water heater could be gnawed electrical wire. Inspect wire.
5) Wires have size markings. 5500 watt water heater needs #10 wire. 4500 watt water heater needs #10 wire but can work with smaller #12 if distance is not long. See label on side of heater for wattage, voltage, etc. Element wattage is water heater wattage even with 2 elements.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html
6) Short inside water heater can be elements or thermostat. Open covers and inspect parts for burning. Screws should be very tight against copper wire. Sediment could fill bottom of water heater cause lower element to short.

Whirlpool temp control on electric water tank


Most electric water heaters have 2 heaters - an upper and a lower, each with it's own thermostat. These are readily accessible by removing the screw covers on the side of the tank. Careful - the thermostats have 240VAC on the terminal screws (unless you have a small 120VAC heater) if the circuit breaker or fuses feeding the heater are still on - turn them off before proceeding. After removing the two screw covers and pulling back the insulation you will see temperature (screw) adjustments for the upper and lower thermostats, with a temperature indicating pointer attached to each screw. Set both thermostats to 125 degrees or so. Push the insulation back in place, replace the covers and turn the circuit breaker back on that feeds the water heater. You should have warm water within 15 minutes and hot water within a hour or so.

If the water still does not heat, then you have to troubleshoot to find the problem. With a voltmeter determine if 240VAC is actually getting to the water heater. Remember, the upper element has priority over the lower element, and if the water is cold, the upper element will try to turn on and this locks out the lower element (only one element is allowed to heat at any given time). The lower element comes on ONLY after the upper thermostat is satisfied. Therefore if the upper heating element is burned out you will never get any hot water. If you suspect this, TURN OFF THE POWER TO THE HEATER and take a resistance check of the upper element.

No hot water


If the water does not heat, then you have to troubleshoot to find the problem. With a voltmeter determine if 240VAC is actually getting to the water heater. Take care here - a defective circuit breaker can give a false 240 volt reading - check for the 240 volts across the upper element (i.e. when the 240 volts has a live load on it, not just an open circuit test).
Also, remember, the upper element has priority over the lower element, and if the water is cold, the upper element will try to turn on and this locks out the lower element (only one element is allowed to heat at any given time). The lower element comes on ONLY after the upper thermostat is satisfied. Therefore if the upper heating element is burned out you will never get any hot water. If you suspect this, TURN OFF THE POWER TO THE HEATER and take a resistance check of the upper element.
