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.

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?

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.

Just replaced both elements to my reliance electric heater..heats fine but after 1 shower i have to reset red button and repeat process daily Whats up? thanks


Replace thermostats.
One of the thermostats is sticking causing overheating that trips ECO reset located on upper thermostat. There is no good way to test thermostats since testing means turning the temperature setting which temporarily unsticks bad thermostat so it looks like it works ok, so replace both thermostats.

Bubbling water at pressure releaf valve on top of valve. valve is rusted. rusty water in pan. Unit was installed new two years ago. Offer suggestions. Thanks


Rusted water usually means anode rod depleted and tank is rusting. Change 570241 anode rod every year or so.
Boiling water could mean bad thermostat causing run-away heating so water is released out of TP valve. Replace 994062 thermostat for 4 gallon.
Leaking water at TP valve could mean bad TP valve: replace TP valve with generic valve from hardware store.

I keep having to reset the red button on the top thermostat!! does that mean the thermostat is going out should i change both or just top one?


You can replace the upper thermostat but usually when this occurs a couple of things may be at play. You may have a small leak in the water heater, especially if over 6 years old. Or you may have a bad element. (I have seen them actually split open when removed). You can reset the top thermostat and make sure the covers and insulation are in place (after checking around both thermostats for any leaks with power off of course.) and wait for the lower element to kick on, if the reset trips after the lower element comes on then probably the element. I usually take an amp reading with a snap around ammeter (about 12 amps draw when operating correctly) only one element operates at a time. Oddly enough, I have never had to replace an element on a single element water heater, only the duals. One last thought, if the tank is run completely out of hot water it can cause tripping as well such as multiple loads of laundry etc since it is operated by a thermo disk. Hope this helps.

Rheem 83xr52-2 50 gal residential water heater. Water temp was low. I cut power at electric panel, removed upper panel on water heater, turned up thermostat, replaced panel and switched power back on at...


You can open the top up again. I would not turn the temp higher than 130 degrees, maximum. However, there should be above the thermostat a red button. This is where the power wires connect to the thermostats and heating elements. Sometimes this button needs to be reset, press it and discern if you hear a click sound. This means that the high temperature safety switch has tripped open and you had to manually "reset" it. There are two thermostats by the way. The water heater usually works this way. There are two thermostats and two heaters. The upper tank heater turns on first and it heats the top half of the tank. Then when the thermostat above is satisfied it then allows the bottom heater to come on and heat the bottom half of the tank. You might want to set the bottom heater thermostat as well. This is made this way because it is actually faster and more efficient to heat the top half first and the bottom half secondly. Try this first with the reset button. We could check voltages, but that requires a level of knowledge and safety that I am not sure that you are comfortable with. Pictures of the upper and lower thermostats and connections will help if the "reset" does not do the trick. By the way, not meaning or implying anything, but did you move the thermostat in the right direction? Sometimes the dials can be confusing.

My model 501, 30 gal, LPG water heater only makes warm water, is this fixable, or should I think replacement?


Look at the flame and see if it's burning blue or yellow. And then see if it's burning all the time. If the flame is yellow and water heater does not make hot water, the thermostat may keep the flame going all the time and use up your gas.

Poor flame color means you should clean the burner or replace the burner. If water heater is exposed to trace amounts of some chemicals, like bleach or pool chemicals or wax, these chemicals get pulled into the burner and will shorten life of burner assembly and combustion chamber.

If the flame is blue and the water is not hot, then the thermostat is the best suspect. The thermostat is part of the gas valve. The gas valve has a copper tube that extends into the water and reads water temperature. If thermostat reads incorrect temp, then the gas valve needs to be replaced with gas valve from local plumbing supply of Lowes.

If the flame is blue, and it runs all the time, then your tank may have a layer of sediment between the flame and the water, and the sediment has caused water heater to become very inefficient.

Now to answer your question:
You can turn up the thermostat dial located on front of tank.
Check your flame and how often burner comes on to determine where problem is.
You can buy a gas valve from Lowes for $65 or from plumbing supply and then replace >> you need a couple wrenches and pipe joint compound and about half a day.
You can clean the burner with wire brush and shop vac.
Remove chemicals from same room as water heater.
If the water heater has sediment build-up, then a new water heater is probably best choice.

You can do some things yourself. If the do-it-yourself steps don't work, then get a new water heater, and you know more about maintaining a water heater because you worked on the old one. Save the new water heater manual. Read the manual because it has ordinary information that will save you money long-term.

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.

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.

I had a water heater that stoped heating. I checked and found the top elment to be bad and replaced it. I have since replaced the bottom lement and the top thermostat and the ohm meter to the thermostat...


WHEN THE ELEMENTS R OHM'ED OUT, THEY SHOULD READ "0", INDICATING THERE IS CONTINUITY. ANY OTHER READING IS A FAULTY ELEMENT. U CAN ALSO OHM THE T-STAT 2 SEE IF THAT IS OR ISN'T THE PROBLEM AS WELL.
