    Default Samsung Dishawasher DMT400RHS Smart Auto, Normal, Delicate lights all blinking

    Model Number: DMT400RHS
    Brand: Samsung
    Age: 6-10 years

    So our Samsung Dishawasher DMT400RHS starts normal but then the Smart Auto, Normal, Delicate lights all start blinking. Then the dishwasher starts what sounds like the drain cycle. Any ideas?

    Hi,

    I located the service manual here: https://www.dropbox.com/s/py1aubwqfp...30515.pdf?dl=0

    Look on Page 41.

    That indicates --->High Temperature Water Supply Error. When 80 C(176 F) or above is detected during water supply.

    Is your water that hot from the water heater into your dishwasher?
