LG Signature Kitchen Suite SKSDW2401 dishwasher will not start or respond

The checks in more detail

LG's platform also uses a control lock, which prevents a cycle from starting. Begin with power. Check the household breaker for the dishwasher and look at the wall switch or the isolator that often feeds a built-in; a tripped breaker leaves a dark panel. Press the power key to wake the display. If the panel is dark but the breaker is on, an unplugged or loosened connection in the kitchen cabinet may be the cause, which an electrician or technician checks with the power off.

Then the door. Close it firmly until it clicks, because a door that is not latched keeps the machine from starting, and open it and look for a utensil or a rack edge that stops the latch. Choose a cycle, then press Start and, on a model that needs it, close the door within a few seconds, since some machines start the cycle only after the door closes. If the display shows a lock icon or says Control Lock, press and hold the lock key for a few seconds to turn the lock off.

Check for a delay-start setting that is waiting for a time. Finally reset: switch off at the breaker for a minute and restore power. If the display lights and a code appears, note it. A machine that is silent with power at the panel, a latched door and no lock may have a failed control or door switch, which a technician can test. Quote SKSDW2401S and the serial number.
