    Aloha everybody.

    I have exchanged numerous messages with Bosch regarding the energy requirements for this unit.

    They told me twice that it requires 208/240 VAC 60Hz 15A ~1600-2000 watts and single phase but I don't trust that because the back of the machine says 12A 220-240 VACand 2000watts but in another place says Pmax 2660-2840 w.

    I asked them to confirm and be very certain about the power phase requirements since I have to get an appropriate converter / regulator for it and I don't want to waste money. She first responded that their tech people said "it doesn't matter", then I became more aggressive expressing frustration and that it most likely does matter and that it could result in significant waste of money. She then replied with a one word email, "single" presumably meaning "single phase".

    Here is a picture of the type of plug on the end of the cord for the washer.

    How can I find out definitively if something like this:

    would run the washer from a conventional 110-120 VAC U.S. Nema 5-15 plug like this:

    I'd really like to have a grounded solution, if possible but I suppose I could ground the chassis of the machine if necessary.

    Thanks for your help!

    Won't work without a neutral. You've got both 220-240V and 110-120V circuits in that pretty box. Only the motor needs 220-240V, everything else requires that neutral line for reference.

    Thanks for the reply.

    What would I need to do to make it work? The converter would not be sufficient? Perhaps you can spell it out for me, as this is not something I have ever dealt with.

    What would allow this to work with conventional U.S. 110-120 V AC power?

    Thanks for your time.
