Your dishwasher is equipped with a leakage sensor located at the bottom center of the unit underneath. If any water is detected, the sensor shuts down power until the problem is corrected. Check underneath FIRST to make SURE there is no water dribbling from a small leak. Look for telltale residue trails left from evaporated water on the hoses, lines, motors, etc.
You can enter diagnostic mode by pressing and holding for 2 seconds the POWER, HEAVY, AND DELICATE BUTTONS. All the l.e.d. s will be lit for 2 seconds, then the software version will be displayed in binary code by the blinking of the WASH, DRY, CLEAN, AND CHILD LOCK l.e.d. s. Next, and this will take some practice, if there are error codes present(sets of blinking lights) you will have to read them to be able to find out where the problem(s) is.
•Press the Heavy + Delicate + Power buttons at the same time for two seconds to enter Service Test Mode.
•All LEDs are displayed for the first two seconds and then Software version will be indicated in Binary Code using LEDS ....Wash / Dry / Clean/Child Lock
•Just like the DMR series you advance through the test next mode by pressing the Normal button . However each test will run by itself (see sequence chart on next page) when test has completed an led will light to indicate test is done and you can then advance to the next test .
•Code list and descriptions located on pp#3. Note: Like the DMR series the codes are displayed during operation or test modes and are not stored in memory.
