Question about Water Heaters

New water tank not working

Hi have 4 month old GE water tank (electric). The water temp has been a bit cooler lately, but we've still always had plenty of hot water. This morning, though we ran out of hot water. After inspection we noticed the tank wasn't turning on. The circuit breaker is on (I flipped it off & back on to be sure) but the tank still isn't turning on. Tonight I'll try the reset button (assuming it has one). Any idea what may have caused this? The water temp was only set at 125 degrees so it wasn't at too high of a temp.

Electric water heater. water not hot enough


Check if tank is hot.
Open drain valve at bottom of tank, and then raise TP lever at top of tank.
If water is about same temperature both top and bottom, and water temp at tap is cooler, then turn up temperature, and check for crossover and broken dip tube.
http://waterheatertimer.org/Crossover.html
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html

If water in lower part of tank is very cool compared with top, then you want to test elements, replace thermostats, and clean sediment out of tank.

Can tankless electric water heater be repaired? Sure.
Is it worth the expense if problem is going to happen again? I can't answer, but can offer resources.

New tank-type electric water heater costs $207 and new tank-type gas costs $320 at local box store.
You can install new tank-type electric yourself in a couple hours. DIY repair on tankless is not easy since parts are not at local box store, and what part do you need, and tankless parts can easily cost more than new tank-type water heater.

Open following link for Bosch troubleshooting resources.
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

GENERALLY, Tankless require .4 gpm (gallons per minute) water flow to activate heating cycle, and then require .25 gmp flow to keep heating cycle going.
For example .4 gallon per minute means faucet can fill 1 gallon container in 2-1/2 minutes
Some tankless units require more water flow, for example .75 gpm

Tankless water heaters have flow sensor that tells computer chip when enough water is flowing to activate heating cycle.
If the sensor is clogged, or if water filter inside tankless unit become clogged with dirt or sediment from hard water, then the unit does not signal enough water flow and will not activate.
Home filtration system and water softener can also slow the flow of water.
Low water pressure and crossover problem on single-handled faucet and crossover on recirculation system check valve and high thermostat setting can also cause heat cycle to not activate.

Tankless cannot be exposed to water with more than 11 grains hardness or parts inside tankless will coat with sediment and not work. Within 2 years the unit will not work, with diminished efficiency from the beginning.
http://waterheatertimer.org/Battelle_Final_Report.pdf

If water is hard, and you cannot soften the water, or if water is dirty and cannot be cleaned, then the best recommendation is to use tank-type heater instead of tankless.

All costs are energy. For average home: Tankless electric is NOT cheaper to operate than tank-type electric. Tankless gas saves $1-8 per month. However, cost of unit and installation, cost of potential repairs and cost of parts, difficulty of DIY repairs, required yearly-monthly maintenance, etc outweigh expected savings.

Installed a new GE Water Heater 40 gal (Gas based) I have the set thermostat at position A. The problem I have is I get very hot water for 10 seconds and then the water gets cooler and cooler quickly. Even...


1) First of all, did you install yourself?
Did you connect hot and cold water pipes correctly.
If hot and cold are reversed, water heater will not work.
Look at markings on top of tank.

2) Is gas valve all the way open? Is valve handle parallel with gas line?

3) Is water heater in a closed closet when it cannot get air?
4) All gas combustion appliances need air supply and outdoor venting.

5) Next thing, is to add a comment with exact size and type of water heater as shown on label on side of tank.
I might be able to access manual for troubleshoot.

Read the manual cover to cover twice.

6) All water heaters come with warranty.
Return water heater to Home Depot, or outlet store and get another one.

My water gets cooler after a few minutes but if i turn the knob up the water gets warm again. I have replaced the elements and thermostats so what else could it be? I did see calcium in it when I replaced...


You replaced elements and thermostats on electric water heater.
You have some hot water and that says:
-Upper element is working
-240V circuit is OK and upper thermostat receiving 240 at terminals L1 L3
-Reset is not tripped, and tank is not overheating so elements are not shorted to ground
-Covers and insulation were re-installed and thermostat is not overheating tank from exposure to cool air.

That leaves following suspects:
1) Sediment build-up located in bottom of tank will interfere with lower element
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html
http://waterheatertimer.org/How-to-test-water-heater-element.html

2) Loose wire between upper and lower sections of tank
3) New thermostat is bad or wire connection at thermostat is loose.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

4) Upper thermostat wired incorrectly
http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html

5) Leaking faucet or TP valve running hot water out of tank, so tank cannot keep up.
Inspect TP outlet and other faucets.

I've had to reset it 2-3 in a week and tried to lower the temp but it still kicks out the reset button.


Good news is tank-type electric water heater if fully repairable by homeowner.
And you can reset water heater as needed until repair is made without damage.

-Tank is tripping reset so you can eliminate circuit breaker and electricity as suspects.
-Tank is not leaking, so TP valve is ok and tank not rusted out.
-Water pressure is fine so outlet and inlet pipes are not clogged with sediment.
-Tank is not short of hot water so you can eliminate leaking faucet as the problem.
-Tank is not short of hot water so lower element is not burned out due to sediment-build-up.

That leaves 6 suspects:
1) Loose wire at thermostat causing arc and overheating: Inspect thermostats and elements for signs of high heat and burning. Tighten screws very tight against copper wire.

2) Upper or lower thermostat is bad: replace both thermostats for $28. Buy generic thermostats at hardware or home center.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

3) Element is shorted to ground in center of element: test elements
http://waterheatertimer.org/How-to-test-water-heater-element.html

4) Stacking: read about stacking.
http://waterheatertimer.org/Stacking.html

5) Factory-installed cover and insulation have been removed from tank. Check that insulation and cover are placed back over thermostat each time so thermostat not exposed to cooler air that will cause overheating.

6) Combination of more than 1 suspect: do full troubleshoot:

These guys have experience with old Monel tanks that reportedly last decades. If your water heater is truely old, it must be either crystal clean water, or good maintenance on your part, or a monel tank or some type of heater made back when they 'made things to last'
I suggest looking at water heater label and posting as much information, with as much detail as possible, to solicit interest and response from the professionals at site

I have a six month old Reliance 40 gallon water electric heater,The thermostats keep shutting the heating rods down, leaving only cold to lukewarm water, no matter how much I adjust the thermostat readings...


1) Try changing both thermostats. Thermostats are frequently defective. Don't change 1, change both, using generic parts from hardware or home center or plumbing supply.
Be sure to put-back insulation and cover over thermostats so they are not exposed to cooler air and cause misread of tank temperature.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

2) Next step would be complete 30 minute troubleshoot, that would isolate the problem and give understanding of water heater operation.

I have a GG40T06/487-246 GE SmartWater Water Heater, it is about 10 years old and now there is leak on the position of the stem of the reset button connecting to the gas valve. Any suggestions to replace...


A 10 year old water heater is at the end of its life expectancy. No sense replacing a gas valve to have the tank rust out next month. I'ld replace the whole unit. Also, install a drip pan, under it and a WAGS safety device. Any water in the pan and the WAGS will shut off he Water and Gas. If your water heater has an expansion tank near by, replace that too.
