Samsung dishwasher won’t start cycle

If your Samsung dishwasher has power but won’t start a cycle, the issue could be due to a locked control panel, a faulty door latch, or an active Delay Start function. Make sure the door is securely closed and latched, and check that the child lock or control lock isn’t engaged. If these are all functioning correctly, the problem may lie with the door switch or main control board.

To reset most Samsung dishwashers, simply unplug the unit from the power outlet or turn off the circuit breaker for 1–2 minutes. This will clear any temporary software glitches. After restoring power, try starting a new cycle. If the dishwasher still won’t respond, there may be a hardware issue that needs professional diagnosis.

Flashing lights on a Samsung dishwasher often indicate a specific error. Common reasons include the door not being closed properly, water supply problems, or an error code like “LC” (leak detected). Refer to your user manual to interpret the specific flashing sequence or code. Correcting the underlying issue should allow the dishwasher to start a cycle.

Some issues—like a locked control panel, tripped breaker, or clogged filter—can be fixed by homeowners with basic troubleshooting. However, if the problem involves electrical components such as the control board, door switch, or wiring, it’s safer and more effective to call a certified appliance repair technician. This ensures the repair is done correctly and safely.
