4. Inspect Dishwasher Power Supply!

Whenever the Samsung dishwasher turns on but won’t start, make sure the circuit breaker, dishwasher power cord, outlet, and power button are in working order.

This is important since even when the appliance is receiving power, supply fluctuations will prevent the wash cycle!

  • Inspect The Power Cord:

Thorly inspects the power cord of the Samsung dishwasher from both ends for any bents, breaks, and defects. 

  • Test The Power Outlet:

Plug another appliance into the dishwasher power outlet to test its workability and avoid plugging the appliance into a power strip or divider.

  • Check The Circuit Breaker

Inspect the circuit breaker and make sure it is set to the ON position. If it is set, then reset it by turning it OFF and then turn it back to the ON position.

Test The Dishwasher!

After making sure the dishwasher is receiving the proper power supply, plug it in, press the power button, and choose the wash cycle settings.

In addition, also include the cycle time and heat temperature settings, and then wait to see if the dishwasher starts. 

5. Check and Test the Water Supply!

Low water pressure or insufficient water won’t allow the Samsung dishwasher to initiate the cycle until it fills with the required water level.

Maybe the valve is turned off, not fully opened, providing low water pressure, or the inlet hose is blocked, restricting the water income.

Here is the way to inspect the dishwasher water supply:

  1. Locate the dishwasher valve at the bottom of the sink.
  2. Be sure that the Water Supply Valve is turned on.
  3. Also, check if the valve is clogged or damaged.
  4. Locate the inlet hose from the back of the dishwasher. 
  5. Carefully remove the hose to acquire good full access.
  6. Clean the hose with a mix of lukewarm water and vinegar.

Important: Also check the Water Pressure by opening your kitchen tap or test it by using Water Pressure Gauge

6. Inspect & Fully Close the Latch!

For starting the Samsung dishwasher, the door latch must be fully closed and engaged with a machine to activate the switch that alerts the board to initiate the cycle.

Hence, it’s necessary to inspect the door latch to see if is working and closing the door properly!

Here is how to check the Samsung dishwasher door latch:

  1. Unplug the Samsung dishwasher from the power outlet.
  2. Unscrew the top screws of the machine to access the match.
  3. Put off the bracket and press on the latch using your finger.
  4. Test whether the latch is moving correctly or it’s broken.
  5. If the door latch is broken or faulty, you’ll need a replacement.

In addition to inspecting the latch, now would be the best time to check whether the door switch is functioning by using an MM600 multimeter.
