yes i have had numerous problems - let me start with saying it works great when it works, tremendous savings as i am single and run it in eMode only. I experienced an average $30 to $35 reduction in power bill monthly, well over $300 savings a year.
Hind sight, I bought the first model they put out, so it was bound to have manufacturing issues. Note to self never buy a first release of any new product.
1 year and one month, unit malfunctioned with an error code. Called GE, turns out they had a manufacturing defect and had copper and aluminum touching on the evaporator. Well these two metals cause corrosion and all the freon leaked out. They said since it was a manufacturing defect they will cover the service call even though it was over a year by one month. Service technician said this is a very commin problem That GE is fully aware of, however it was not supposed to happen until after year 3 and thus GE normally will not pay service call only parts. He said he already did three that month and those customers had to pay for the service.. So i got lucky, running in eMode only caused the manufacturing defect to happen sooner..
2 years later, (little over 3 years total) water was all over the floor, first suspect the tank is leaking. GE had me run it in high dollar electric only mode (no heatpump) for several days to see if it stopped leaking. It did, so they said most likely the condensation drip pan was cracked. They said this is very common with that model especially if it had a service call and the evaporator was replaced (which mine did have done).
GE refused to honor the warranty, the drip pan is an integral part of the hot water tank and they have no way of replacing that part without replacing entire hot water heater. Thus they said I would have pay an unknown amount of money based on how long it took technician to spread silicon over the cracked plastic condensation pan. I demanded my replacement part they refused, i said it is not my fault you can't replace a small part, so according to their warranty they need to send new hot water heater because warranty says part replacement not part repair. Mind you they will only guarantee the repair for 30 days. Tray cracks because they directly mounted the evaporator to a plastic tray which is glued to hot water tank. basic engineering, evaportor core gets really cold and the metal shrinks, then goes back to ambient and expands repeatedly during normal use. Plastic does not shrink and expand like metal, plus it does not get freezing cold like the avaporator.. Well they directly bolted the two parts together, eventually the plastic is going to fail which it does well before the ten year warranty period. (NOTE: newer model has a replacable condensation drip pan)
so i looked more closely at the unit and found even the support brackets had failed and were fractured from the manufacturing defect, i had to get service technician out again and this time they had no repair and after a long long battle they finally agreed to send me a new hot water heater.. GE was shady about this, they know for a fact they have a manufacturing defect and are ripping people off. They should just honor their warranty and replace the part, since the part can not be separated from entire hot water heater then entire hot water heater should be replaced under the 10 year part replacement warranty.
They probably need a class action lawsuit brought against them, to protect those consumers not willing to fight as hard as i did. GE should be ashamed.. It xxxx for them they made a manufacturing defect, but they did. It was a very stupid manufacturing defect at that, which could have easily been avoided. Remember Federal government paid for part of this hot water heater as well via their energy star tax credit. So really all working tax payers are getting shafted by GE being as they paid the government taxes in order for the government to pay me the tax credit.
if this happens to yours demand a new hot water heater, do not except a parts repair. Warranty states parts replacement warranty for 10 years, not parts repair that is not even guaranteed past 30 days to work but will cost you approximately $300 to have repaired.
once again it is still a fantastic idea and product when working, mine already paid for itself in electric cost savings before it broke down the second time. So It does work when working, just make sure you get at least reviosion 2 which you will by now because they discontinued the original one a long time ago after they discovered the manufacturing defect.
