Starting a Samsung dishwasher in three steps

To start your Samsung dishwasher, load your dishes, add detergent to the dispenser, close the door firmly until it latches, and press the Start/Cancel button. The cycle will begin when ready. If your model has a delay start feature and you want to run it later, press the delay button before pressing Start, then select your desired time.

Most Samsung dishwashers power on automatically when you open the door and power off when you close it. You do not need to flip a separate power switch. The control panel lights up as soon as the door opens, and you are ready to select your cycle.

Key Takeaways

  • Load dishes, add detergent to the main dispenser (and rinse aid if your water is hard), close the door until it clicks, then press Start/Cancel to begin the cycle.
  • The dishwasher powers on when you open the door and the control panel becomes active — no separate power switch is needed.
  • If your model shows a lock symbol or "Door" message on the display, the door is not fully closed; push it firmly until you hear a click.
  • Delay start lets you schedule the cycle to run later; select the delay time before pressing the Start button.
  • If nothing happens when you press Start, check that the door is latched and that the control lock (if your model has one) is not activated.

Loading dishes and adding detergent

Place dishes in the racks with soiled surfaces facing inward toward the spray arms. Do not block the spray arms or the detergent dispenser door. Load the lower rack with plates, bowls, and cookware; use the upper rack for glasses, cups, and smaller items. Leave space between items so water can reach all surfaces.

Open the detergent dispenser door on the inside of the door panel. Pour liquid or powder detergent into the main compartment until it reaches the fill line — typically about 15 to 20 milliliters for a standard load. If your water is hard or you have heavily soiled dishes, you can add a small amount to the pre-wash compartment as well. Close the dispenser door firmly until it clicks.

If your Samsung model has a rinse aid dispenser, fill it with rinse aid to help dishes dry faster and reduce spotting. The dispenser is usually located on the inside of the door or on the side wall. Rinse aid is optional but recommended if your tap water is hard or mineral-heavy.

Selecting a cycle and pressing Start

Close the dishwasher door and push it firmly until you hear a click and the latch engages. The control panel will light up. Use the buttons or touchscreen to select your desired cycle — common options include Normal, Heavy, Eco, Quick, and Delicate. The display will show which cycle is selected.

Once you have chosen your cycle, press the Start/Cancel button. The display may show a countdown or confirmation message. The dishwasher will begin filling with water and the cycle will start. Do not open the door during the cycle, as this will pause the wash and may affect cleaning performance.

If you want to delay the start, press the Delay Start button (or Delay button, depending on your model) before pressing Start. Use the arrow buttons to set the delay time — usually in one-hour increments from 1 to 24 hours. Then press Start. The dishwasher will remain idle until the delay time expires, then begin the cycle automatically.

Troubleshooting when the dishwasher will not start

If you press Start and nothing happens, the most common cause is that the door is not fully latched. Open the door, check for any dishes or debris blocking the latch, and close the door again with firm, steady pressure until you hear a distinct click. The latch must engage completely for the dishwasher to operate.

Check the control panel display for error messages or warning symbols. A lock symbol or "Door" message means the door is not properly closed. A "Control Lock" message (on models with this feature) means the buttons are locked to prevent accidental changes. To unlock the controls, press and hold the Control Lock button for three seconds.

If the display is dark or unresponsive, make sure the dishwasher is plugged in and that the circuit breaker has not tripped. Check your home's electrical panel and flip the breaker back on if needed. If the dishwasher still does not respond, consult your user manual or contact Samsung support.

Understanding cycle times and what happens during a wash

Samsung dishwasher cycles typically run between 2 and 4 hours, depending on the cycle selected. Eco cycles are longer but use less water and energy. Quick cycles are shorter but work best on lightly soiled dishes. Heavy cycles run longer to handle baked-on food and heavily soiled cookware.

During the cycle, the dishwasher will fill with water, heat it, spray dishes through rotating arms, drain, refill, and repeat. You will hear the motor, water flow, and spray arm movement. Some models have a quiet mode or reduced noise setting if you prefer a quieter operation.

When the cycle is complete, the dishwasher will drain and the display will show "End" or a completion message. The door will unlock automatically on most models. Open the door carefully, as dishes may still be warm. Unload from the bottom rack first, then the top rack.

Using delay start and other common features

Delay start is useful if you want the dishwasher to run during off-peak hours or when you are away from home. Press the Delay Start button, set the number of hours you want to wait (usually 1 to 24 hours in one-hour increments), then press Start. The dishwasher will remain off until the delay time expires, then begin the cycle automatically.

Some Samsung models have a Half Load button, which reduces water and energy use when you are running a partial load. Press this button before selecting your cycle if you have fewer dishes than usual. Other models may have options for Extra Dry, Sanitize, or Soil Sensor, which adjusts the cycle based on how dirty the dishes are.

If your model has a Child Lock or Control Lock feature, you can set up it to prevent accidental button presses. Press and hold the Control Lock button for three seconds until you see a lock symbol on the display. To unlock, press and hold the same button again for three seconds.

Frequently Asked Questions

Why does my Samsung dishwasher display say "Door" and won't start?

The door is not fully latched. Open it, remove any dishes or debris blocking the latch mechanism, and close it firmly with steady pressure until you hear a click. The latch must engage completely before the dishwasher will operate. If the door still will not latch, the latch mechanism may be damaged and you should contact Samsung support.

Can I open the dishwasher door once a cycle has started?

Yes, you can pause the cycle by opening the door. The wash will stop, and you can add or remove items. Close the door to resume the cycle where it left off. However, opening the door frequently can affect cleaning performance and increase cycle time, so it is best to avoid it when possible.

What if I add detergent but the dispenser door does not open during the wash?

The dispenser door may be stuck or blocked by a dish. Make sure you closed it firmly until it clicked, and that no items are pressing against it from inside the dishwasher. If the door still does not open, the dispenser mechanism may need service. Check your user manual for troubleshooting steps or contact Samsung support.

How do I know which detergent to use in my Samsung dishwasher?

Use any standard dishwasher detergent — liquid, powder, or tablet. Samsung does not require a specific brand. Follow the detergent manufacturer's instructions for how much to use based on water hardness and soil level. Tablets are convenient because they dispense automatically, while liquid and powder give you more control over the amount.

Is it normal for the dishwasher to make noise during a cycle?

Yes. You will hear water filling, the motor running, spray arms rotating, and water draining. These are normal operating sounds. If you hear grinding, rattling, or unusual noises that sound like something is broken, stop the cycle, open the door, and check for loose items or debris in the spray arms or filter.
