Most common repairs needed to fix a Samsung dishwasher

Electronic Control Board Replacement

When your dishwasher won’t start a cycle, a defective electronic control board could be causing the problem. The control board will freeze up and fail to start a cycle when its internal memory and logic is corrupted. A failed internal electronic relay or bad electronic part on the circuit board could be causing the control board to freeze up and not start a cycle. Determining whether a control board is defective is difficult. Have a Sears Home Services technician diagnose and repair your dishwasher when it won’t start a cycle.


How to replace a dishwasher electronic control board

Power Supply Board Replacement

A damaged power supply board could be causing the problem when your dishwasher won’t start a cycle. The power supply board provides the electrical current needed to operate components such as the fill valve and pumps in the dishwasher. A damaged power supply board won’t provide power to components to operate the dishwasher. When your dishwasher won’t start a cycle, have a Sears Home Services Technician check the power supply board and replace it if it’s damaged.

Door Switch Replacement

When the dishwasher won’t start a cycle, a failed door switch may not be detecting that the dishwasher door is shut. Microswitches in the door switch assembly can break or short out. If the control doesn’t detect that the dishwasher door is closed, the dishwasher will not fill with water and start washing. Because the door switch is hard to access and test, have a Sears Home Services Professional visit your home and repair your dishwasher when you suspect that the door switch failed.

Why is my Samsung dishwasher not starting the wash cycle?

When your Samsung dishwasher is not starting the wash cycle, start by following the troubleshooting tips shown in the owner’s manual.

  • Make sure that the door is shut fully. Push in firmly on the top of the dishwasher door to make sure that it latches properly.
  • If the control panel won’t light up, check the power going to the dishwasher. Make sure that the power cord is plugged in and reset the house circuit breaker for the dishwasher if it has tripped.
  • Disable the control lock feature if it’s on. Press and hold the button marked with the padlock icon to turn off the control lock.

If these basic troubleshooting steps don’t help, follow the expert tips in this DIY troubleshooting video to resolve the problem with your Samsung dishwasher not starting:

Check the dishwasher door switch

A faulty door switch will keep the dishwasher from starting. If the door switch is stuck in the "open" position, the dishwasher won't start because it's waiting for you to shut the door—even if you did shut the door.

To test for a faulty door switch, check the resistance through the door switch with a multimeter:

  1. Disconnect electrical power to the dishwasher by shutting off the house circuit breaker or unplugging the dishwasher.
  2. Remove the screws from the outer edges of the inner door panel.
  3. Separate the outer door panel and the control panel slightly from the inner door panel, and rest the outer panel on the floor while you disconnect the user interface control wire harness.
  4. Pull off the outer door panel and control panel.
  5. Release the door latch assembly from the inner door panel and unplug the wire harness from the door switch.
  6. Press the door switch lever to simulate a closed door that's engaging the door switch.

With the multimeter set to check resistance, place a meter probe against each of the door switch prongs. You should measure near 0 ohms of resistance, or continuity, through a working door switch.

If you measure infinite resistance, replace the door switch because it's defective.

These expert tips may help you resolve a starting problem in your Samsung dishwasher. If you’re unable to find and fix the starting issue on your own, schedule dishwasher repair service and we’ll send a Sears Home Services technician to your home to fix the problem.

Thorough

James called to give an estimated arrival time. He was professional and personable. He had 2 professional ideas of the problem and found 1 was correct, but he didn't stop there. He did a thorough check of the appliance. 1 small part was needed. He ordered the part to my house. Fortunately, he was able to schedule for the next week, just before Thanksgiving. As before, he called ahead, arrived and quickly fixed the problem. My appliance is working perfectly.
