Question about General Electric GE SmartWater Household Water Filtration System - GNWH38F

1 Answer

Hot Water inconsistent

I bought a GE SmartWater 6-year Gas Water Heater four years ago. No problems until about 2 months ago. If I shower about 5am, I have hot water. Go to work, return home and do evening dishes and/or clean up after about 12 hours and I still have hot water. However, on five occasions, if I work out in the morning and wait until early afternoon to shower, I run out of hot water in no time. Takes about 45 minutes to recover. GE thinks it's a plumbing issue/leak and not their water heater (over the phone diagnosis). My dad thinks it's either a faulty thermostat or a possible buildup of sediment on the bottom so that the sensor does not know the water is cold. Is this possible? I can't believe it could be a plumbing issue as I always have water and have had no leaks. I just don't get hot water for very long if I wait until later in the day. I thought the selling point of the SmartWater system was to replenish hot water quickly. Really baffled as to the cause and don't want to call a plumber when I really think it's the water heater itself.

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.

Id try raising the chimney until you can get the smoke from a piece of paper to get sucked up under the draft hood. I believe theres a different problem then a cold pipe.raising the chim.might not be the answer.

Water is found leaking at the bottom of the tank, near the plastic cap, at the centre of the tank. What actually happens and how to resolve. The heater has been installed more than 5 years ago. From the...


A) Calculate date of water heater manufacture from serial number located on side of tank:
http://waterheatertimer.org/pdf/WaterHeaterSerialNumberDecoder.pdf
Date of manufacture is not date of installation.
Warranty is usually from date of manufacture
Serial number also shows tank size in gallons, tank volts and watts, and whether tank has 1 or 2 elements.

B) Troubleshoot leaking water heater:
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html
Several things can be looked at to see where leak is coming from.
Carefully go over tank pipes and valves to eliminate every suspect.
Final suspect: tank is rusted out.

C) If tank is rusted out, then tank needs to be replaced before it ruptures.
Ruptured tank can cause major damage and water runs until shut off.
To prevent rupture, turn off power to heater, turn off valve located above tank, open tub faucet for a moment to relieve pressure on tank.
Turn on heater only when needed until new tank is installed.
4500 Watt water heater produces 21 gallons hot water per hour.
Shower uses 6-9 gallons hot water. Bath uses 12-14 gallons hot water.

"It is possible to limp along with a failed water heater if the leak is slow and if you turn off power and water when not using hot water. That trick could buy time, possibly up to 3 months. With time, you can consider how to make the system do more for less as well as comparison shop, get competitive bids, etc"

D) Now you're home is safe from damage.
If tank is only 5 years old, it rusted out pretty quick.

There are three things you can do so next heater lasts longer.

1) Learn about anode rods, and inspect anode rod every 1-3 years.
Loosen anode rod before installing new tank so replacement is easier.
http://waterheatertimer.org/Replace-anode-rod.html

2) Attach electrical ground wire between hot and cold pipes to prevent stray current from reducing life of water heater
http://waterheatertimer.org/9-ways-to-save-with-water-heater.html#straycurrent

3) Flush tank each 6 months to prevent sediment

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.

probably has a bad heating element. May be a little limed up also. Drain the heater and replace the elements. Take a special tool to remove and replace the elements.

PowerStar. Model 45-557701 tankless water heater water wont get hot...it slowly quit getting the water hot


Hot Water Hot to Cold And back. I had that problem for 2 years. I had a very large shower head from the time I installed the tank-less hot water heater and the water temp would change from one extreme to another. Over time my shower head had stopped working as well as it did so I bought a smaller shower head and installed it and amazingly my water temperature quit changing temperature. I now turn my water to what temp I want and it stays there. It's been working correctly for 6 months now ... until yesterday and it quit working completely which is the reason I'm on here. lol

Our second unit just failed and needs a new controller more money


The only Bosch tankless I have ever touched have been the 3 I have taken out and replaced with Rinnai. I think Bosch/Paloma/etc. have two problems:

1. They do not properly certify technicians before allowing them to install these units.

2. Their product is mediocre at best.

The biggest problem I've seen is that people don't vent them properly. The last one I pulled out had a combined vent length of 55'. 55 FEET! Absurd!
The units was condensing so much inside the vent that it washed out 2 gas control valves in ONE YEAR.

Buy Rinnai, buy Takagi, buy Noritz....maybe even a Navien (new player...time will tell)
+
Factory certified technicians, preferably equipped to do the gas & plumbing without having to sub it out.
=
Years of trouble-free hot water.

Good Luck.
