    What should the resistance check value be on a good element?

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.

    Around 10 to 12 ohms for a standard 4800 watt element.

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.

Why is the reset on my electric hot water heater keeps tripping


Have you tried another breaker? Check the ground wire and natural. And make sure no water around any wires.

For residential water heater, 30 amp is best... but must have 10 gauge wire.

If you have 12 gauge wire, then use 20 amp breaker and install 3800 watt elements in place of 4500 watt elements

Electric wh high temp shut off button keeps resetting


Water heater has upper and lower elements. Only one t-stat. Check to see where tstat is set to. Turn down to lowest level. If breaker still resets then replace tstat. It is letting the water get to hot no matter what setting it's on. So water is getting so hot that it trips breaker.

Water heater


Guessing that you have 240Volt residential non-simultaneous electric water heater? And that you have 30 amp breaker and 10 gauge wire. And that water heater is located within 100 feet of breaker box. And there are no leaks running hot water out of tank. And that you installed fully brand NEW elements of same wattage as old elements. And that fully brand new thermostats were installed, and wiring exactly duplicates wiring that was present before. And that factory-insulation was re-installed over elements and thermostats.

1) Guessing the 'hot water shut off' means the ECO red reset button located on upper thermostat keeps tripping and cutting off electric power to water heater?

http://waterheatertimer.org/images/WH-w-combined2-1000.jpg
http://waterheatertimer.org/How-to-test-water-heater-wires.html

2) If the ECO is tripping, then water is getting too hot, or there is shorted wire located near the upper thermostat, .
Typically replacing both thermostats and replacing elements will solve this problem .... assuming that new thermostats and elements are good, and wiring correct.
Double-Check your wiring on upper and lower thermostats.
Test wires for short.
Make sure factory-insulation is re-installed over thermostats so cool room temperature will not affect temperature reading.
Check that thermostats sit flat against steel tank.
Many short draws hot water can also cause stacking event that will trip circuit breaker.

3) Add comment and say what you find using checklist above.
Be careful to explain findings fully, using same words found on links above, so illuminated diagnosis can be made.

Whirlpool E1F50RD045V 50 gal elec. , top element is on bottom element is not getting 208 v, removed both legs from bottom stat has120v on each side not getting 208 from top , is their a relay not closing...


Sounds like you might have a thermostat problem, or burned out lower element
Lower thermostat and both elements will test for 120V at all times because upper thermostat only cuts off one leg of 240V circuit, and other leg is hot all the time.

Yes, the elements alternate being turned ON.
This is called non-simultaneous operation.
Look at label on side of tank: Each element has rating of 4500Watts, but tank rating is also 4500Watts > that shows that both elements are not ON at same time.
This is standard wiring for water heaters.
http://waterheatertimer.org/How-it-works.html

Water heaters can we wired differently, for example converted to simultaneous operation where upper thermostat and lower thermostat are no longer wired together, so upper and lower parts of tank are independent.
Lower thermostat is replaced with ECO protected thermostat identical to upper thermostat.
Another 240V circuit breaker is added to breaker panel, and that 240V line runs directly to lower thermostat. So upper and lower thermostats are each on separate 240V line.
The advantage of simultaneous is faster recovery of hot water, but downside is probably higher electric bill. Simultaneous wiring is usually reserved for larger tanks like 80 gallons, where elements can fall behind the amount of hot water needed.
Otherwise, ordinary non-simultaneous operation is proven to be satisfactory, if your home has not experienced shortages.

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.

4) Bad upper element. Test upper element.

My hot water will not get hot at all. Model SE40M12AA01 Stop getting hot over night. Breaker to heater was tripped, I reset it and still no hot water.


Your upper thermostat on the hot water tank may be shorting out causing your breaker to trip. Remove the outer panel door on the side of the hot water tank and test for power going to the elements. Also check for water as the tank may be leaking and causing the short

Water Too Hot


needs new thermostat(s) If the whole tank is heating( next time it trips, before using any hot water check the lower tank thru the lower element access(breaker off) If the lower tank is hot-you need a new lower thermostat. if just the upper part of the tank is heating -you need an upper thermostat.
