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.

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.

Add a comment as needed while you work on tank.

I own a house with an electric GE hot water heater. 8ESOT12AA01 Serial # 090122 5750 I do not know how old the hot water heater is and advice about when it should be replaced. No leaks to date but I...

GE is made by Rheem, but the market is always changing. Rheem-based serial number shows tank was made in 1990.
Tank will last as long as anode rod(s) protects steel tank from rusting.
If your tank has two anode rods, then tanks lasts longer.
That's how companies determine if water heater is '6-year' or '12-year.'
I don't have manual for your product to say if you have 12 year tank. Side of tank might have information blurb besides mandatory label that shows serial number.
You can update your water heater by replacing anode rod(s) assuming they can be loosened and removed after this number of years, which is a big IF with old heaters. Your plumber might have impact wrench he uses to see if anode can come out.

If the water heater is making gurgling rumbling and/or crackling sounds then tank has sediment build-up.
You can also get a baseline of rust by flushing tank and watching if water is very rusty.

If you flush tank regularly, and inspect anode every 1-3 years, a tank will last many years longer than manufacturer's label.

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.

7) Read information how to install:

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.

3) Element is shorted to ground in center of element: test elements

4) Stacking: read about stacking.

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:

My Rheem electric hot water heater occasionally leaks water then stops completely. This has done this three times now over the pact couple years.

It sounds like TP valve is releasing water, but you don't describe where water is located.
Run through process-of-elimination check list on following link:

1) If problem is TP valve, event could be caused by 'stacking'
Stacking is where you draw amounts of hot water many times in succession.
Top part of heater is plenty hot because water heater is keeping up with hot water draw.
Incoming cold water enters bottom of tank through dip tube causing thermostat to read cool temperature and activate burner or element. This causes higher than ordinary temperatures at upper part of tank and TP valve reacts by releasing water.

2) TP valve could be going bad.

3) Improper venting can cause gas water heater to have water on top of tank or dripping down inside tank where it shows on floor after rusting out combustion chamber.

4) Thermostats are old or not reading correct temperature.
Turn down thermostats:
Replace gas valve on gas water heater, and flush tank.
Replace electric water heater thermostats

Rheem water heater model #82V661 serial # RH0106D11663 leaking water at lower panel. Water is coming from above wiring and control panel. Is this fixable or need to be replaced? Mfg date is 01/2006

You have 240volt electric water heater
Check both elements for leaking.
Check top of tank for leaking pipes.

If water heater is leaking from side of tank, then tank is rusted out and could rupture.
This tank must be replaced.

My friend welded his tank to get more life out of tank, but he assumed the risk.

Hot water heaters are under pressure from heated water which expands.
If tank ruptures, water will flood out of tank and water will run until shut-off is turned OFF.
This causes major damage inside home.

Protect yourself first, and then let's talk more.
1) Turn off water at shut off located on cold water line above tank.
2) Turn off power to water heater:
Gas heater, rotate valve to 'pilot' so pilot is lit but burner does not turn ON.
Electric heater, turn off circuit breaker.
3) Open tub spout on hot side and let run a bit to relieve pressure.
4) Now your property is safe.

You can limp along with failed heater if leak is slow.
Turn heater ON when you need hot water.
Typical Gas heater makes 41 gallons hot water per hour.
Typical Electric heater makes 21 gallons hot water.
Shower uses 5-9 gallons hot water, bath uses 12-14 gallons hot water.

If you are going to install heater yourself:
Look at label on side of old tank to identify size and particulars.
I buy ordinary heaters from Lowes and Home Depot and always buy scratch-n-dent models when possible, because superficial damage to outer tank does not lower lifespan of heaters I have installed.
Buy same size heater if it worked fine before.
Buy new flexible water connectors.
Set water heater in drip pan.
Offer 10% less than price shown. Make them deal with you. Shop Ace hardware, Lowes, Home Depot. Kick the tires since you have a bit of time.

I know you have electric heater, but many folks read these answers, so I include info on gas too.
#1 rule) tankless heaters are a rich-man's toy, because tankless will never pay you back, and will become major money pit if you encounter 1 repair. Electric tankless heaters require larger electric service box. Gas tankless require larger gas line (larger gas line, more gas consumption, bigger bill unless you cut consumption)
2) How to install gas heater:
3) How to install electric heater:
Read link above because many of same steps apply to electric.
The difference with electric, is turn off power, disconnect wires, and reconnect wires exactly like before. Set electric heater directly on insulated surface like dense blue styrafoam. Cut styrafoam in circle so it fits inside dip pan. Wrap entire electric heater with insulation blanket, except don't cover TP valve.
4) Connect bare copper jumper wire between hot and cold pipes to prevent stray current corrosion which will shorten life of tank. Make sure cold water line is grounded.

Re: Rheem Water Heater Model# 82V52-2 (date of Mfg 07/2007) A few months after an installer replaced our old water heater, we had an event one day where there was no hot water. The installer advised how...

There is a solution.
Ordinary tank-type electric water heaters are fully repairable by homeowner.

You have a new heater that works fine most of the time, but reset button trips.
That says tank is getting correct electricity.
It says that elements are good.
And you don't have sediment problem with new tank.

If you do not want to test parts, then replace upper and lower thermostats for $28.
The reason I suspect defective thermostat is that tank has 4 parts: 2 elements and 2 thermostats, and you have plenty of hot water so elements are probably good.
The reason I replace both thermostats is to avoid uncertainty.
Tighten screws very tight against copper wire.
Be sure to put back insulation and covers on water heater so thermostats not exposed to cool air which can lead to overheated water.
Then send bill for $28, plus labor and aggravation to Rheem
Your plumber should have done this for you as part of warranty, but sometimes self-sufficiency is valuable.

If you want to test water heater parts before replacing anything, then buy multimeter and take 30 minutes to become electric water heater expert:
Buy cheap multimeter at home center.
When testing continuity or testing elements, rotate multimeter dial to Ohms.
When testing for voltage,, rotate multimeter dial to 240-250-277 VAC

You can also double check anything fixya or plumber tells you by posting question on professional water heater forum like the Tank:

Hot Water inconsistent

Something you can do, following your fathers logic,   is to attach a hose to the drain of the tank and run water from the bottom of the tank into a drain untill all the sediment is removed (Water runs clean). This is normally done once a year as preventive maintenance  on all tank type water heaters. The logic sounds good to me.
