washing machine, low power consumption

    I want to put a washing machine in my motorhome, i have a couple of solar
    panels on the roof, and will be running it off my inverter (antares 1600
    watt soft start, 230 volt as i'm in the UK)

    The washing machine i have in mind is a compact front loader, mechanical
    timer so it should run on the inverters output which is a modified sine
    wave.

    The washer will most likely be a Eudora euronova or mininova, made in
    austria, and popular in europe in small appartments as well as motorhomes
    and caravans.

    Now this washer has a heater element in it, takes about 2 killowatts, the
    motor and pump only pull about 250 to 300 watts depending on if it's
    spinning or just tumbeling.

    Obviousely it's daft to run a heater element off an inverter, not that i can
    anyway, does anyone know if a washing machine will throw a wobbely if the
    heater element is disconnected?

    i.e. does it take a resistance reading when it switches the element on, and
    if it's not present shuts down??

    I know the machine will have the element on untill the water temp comes upto
    the pre set level, unfortunately most of these machines are cold fill only,
    i plan to fill it with warm water, i have hot water at 80 degrees C
    available, and will use a thermostatic mixer valve to set the temp to what
    ever the temp on the machine dial is... i.e if doing a 40 degree wash, i'd
    set the water inlet temp to just over 40 degrees,

    anyone know if this will work in fooling the machine into going onto the
    next step of the wash without trying to power the heater element up.. which
    wont be available anyway?

    Anyone done this before?

    i know the ideal solution is a hot and cold fill washer, but it's very hard
    to get any compact sized washer over here, let alone be picky about things
    like hot and cold fill options. so it looks like i'll have to adapt the
    machine to suit my needs.

    Doesn't it have a 'cold' setting? Most washers allow you to wash clothes
    in cold water. Presumably this would turn off the heater element.
