If the Samsung DW80B7070 stops mid-cycle, start with the door: the manual says to resume after opening the door by pressing START first and then closing the door, and that a running cycle is changed or cancelled by pressing and holding START for 3 seconds. Then read the display: an information code with a warning sound is the dishwasher's own stop. 3C is a pump operation check, PC a zone wash function check, HC2 a dry heater failure check and HC4 a dry heater overheat check, and each has a simple owner step (turn off and on, or unplug) before service. The dishwasher also powers off automatically when its cycle is complete.
