Most common repairs needed to fix a Samsung dishwasher

Electronic Control Board Replacement

A dishwasher display not working problem could be caused by a defective electronic control board. The electronic control board sends power to the control panel to power up the display. When the display is dead, it could be because the electronic control board isn’t sending electrical current to the control panel. Fixing this type of dishwasher problem requires advanced technical expertise. Have a Sears Home Services Technician diagnose and fix the problem to get your dishwasher back in working order.

User Interface Control Replacement

When the dishwasher display is not working, a damaged user interface control could be causing the problem. The user interface control connects to the electronic control board through a wire harness and sends signals to the control board to help control the dishwashing cycle. A bad power key on the user interface control can prevent the dishwasher from powering up. Also, a stuck key on the user interface control can cause the electronic control board to stop the cycle and the dishwasher won’t work until the damaged user interface control is fixed. Have a Sears Home Services Repair Expert visit your home and replace the user interface control if it’s damaged.

Power Supply Board Replacement

When your dishwasher display is not working, a damaged power supply board could be causing the problem. The power cord connects directly to the power supply board and the power supply board sends power to the electronic control board to power up and operate the dishwasher. When your dishwasher is completely dead and it is getting power through the power cord, you’ll need to have a Sears Home Services Technician check out the power supply board and replace it if it’s damaged.

What to expect when you experience a Samsung dishwasher display not working issue

How is the display not working problem fixed?

Correcting most display not working problems usually involves replacing the electronic control board, user interface control or power supply board. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.

Sears Home Services recommendations for a dishwasher display that is not working

When the dishwasher display is not working it can be for many reasons. To avoid replacing unneeded parts we recommend having a Sears Home Services professional perform diagnostic tests to identify the root cause of the problem. Our technicians are experienced at diagnosing all types of dishwasher failures.

What to look out for with a dishwasher display not working diagnosis

Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your dishwasher problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.

A blank or flashing display on a Samsung dishwasher hinders cycle selection and tracking. Failing control boards or dislodged cables frequently cause this. Instead of running cycles in the dark, turn to dishwasher repair near me. Once the display is fixed, you can easily manage each load’s progress.

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.
