Hybrid Water Heater problem

Jamie HallJamie Hall Posts: 10,171Member
edited April 15 in THE MAIN WALL
In one of the other places I manage, the owner -- for reasons known best to herself -- had a State Electric Hybrid water heater installed. Model HPX-66-DHPT120.

The owner is not there much in the spring and fall, like now, but the water heater is left running. Problem is...

Pretty much anytime when I go check the place and hot water hasn't been used for a week or so I find the blessed contraption beeping merrily away and flasshing an error code "ECC" which, helpfully, tells me to call tech. support. It did it first when it was in vacation mode, but has done it again several times after being reset and run in regular mode,

Tech support is not all tht helpful.

Any insigth or bright ideas? I"m anything but an A/C or compressor tech., and I don't want to learn at this stage of my life -- but I'd sort of like to have a clue.

    @Jamie Hall

    I looked at the manual which is on line I assume you have one. I skimmed through it. I would get the manual and see if there is something wrong with the installation. Ambient temperature they list as between 45deg -120deg. check air filter and condensate drains etc BLAH BLAH.

    It gives some error codes

    The manual says "ECC- Heat Pump Compressor Not Operating"

    Jamie. I have had only a couple of issues with these things as they are new technology. (At least for me anyway.) But had a similar situation.
    One was installed in a room that was enclosed so much that the thing over heated. No one saw this coming as these hybrids are supposed to take surrounding air and use it to heat the water. Nevertheless the thing was busted. Compressor blown.
    But !
    On those units you can change the mode. I forget how they explain it on the unit, but one of the modes you can change it to is to conventional? I think it was called? not sure of the language. Meaning, the conventional heat elements are used only. No hybrid, no external air etc.

    If you make the selection that just uses the heat elements in the water. (essentially you are bypassing the heat pump/compressor.) Than you should be able to tell if the compressor is or is not working as it will reset in the mode cycle , or so it did for me. When you make the mode change it will default to original. I do not like these units because of this.
    After you do this go back to your prefered mode and monitor it to see if it is working correctly.
    ECC is a common error code in many brands of these units and is not very telling as to what is wrong.I have yet to come across a rep or tech support that has been able to tell me what the heck I did to get it working.

    I also am not a AC tech..... Licensed Plumbing Contractor/ Steam Fitter for a long time now. I am only offering my advice from a few of my own experiences. Hope others chime in to lend their ideas.

    @Jamie Hall

    I went back on State's web site. The only "manual" I can find is more of a "users manual" and doesn't get real technical.

    It seams as though they have technical information and real manuals for other equipment.

    I guess it's "new technology". Apparently they will build and ship and leave it to the installers and owners to figure out how they work.......then write the manual at a later date.

    It doesn't surprise me at all. I like State but they are owned by AO SMITH who I dispise.

    @EBEBRATT-Ed Do you think the menu pads are all made by the same company? I have seen a few of the hybrids from different manufacturers. The selection, or menu key pads seem the same?

    @Jamie Hall How did you make out with this.
    And was the unit put on vacation mode before this all started?

    It was. It's on electric only now while we keep trying to figure out what it's doing... or not doing. It's unpredictable. I'll keep you all posted.
