You press the start button, and .... nothing happens. You push a little harder. Still no response. Suddenly, you're battling an uncooperative dishwasher. We know how frustrating that can be. If you have a problem with your dishwasher buttons not working, you can't wash your breakfast dishes or run a load of pots and pans after dinner.

Common Reasons for Buttons on a Dishwasher Control Panel to Stop Working

Few betrayals sting as much as your dishwasher's buttons not working. Before you give up and order a new one, take a look at the most common causes of button issues. You may be able to pay for repairs instead of buying a new unit.

1. Dirt Buildup

Take a good look at your dishwasher. Is it sparkling clean, or do you see dirt and grime around the control panel? Even if your housekeeping is on par with Martha Stewart's, your dishwasher may have food particles, water spots or grease on it. For example, if a dishwasher sits near the stove, it's easy for oil to splatter when you fry food. Over time, dirt buildup can interfere with the normal operation of your dishwasher control panel.

To clean the appliance:

Turn off your dishwasher at the breaker.
Use mild dish soap and a nonabrasive cloth to clean the control panel.
Dry the control panel thoroughly.
Restore the power.

If you don't feel comfortable turning off power at the circuit breaker, call a home service professional.

2. Child Lock Engaged

Sometimes your dishwasher is working just fine, but the buttons don't work because you (or a curious toddler) engaged the child lock without realizing it. The easiest way to fix this issue is to look for a lock icon. If it's lit, consult the product manual for instructions on how to disable it. For most models, it's as simple as pressing the lock button for a few seconds. If you don't have the original manual, use your favorite search engine to find a digital copy.

If the lock won't disengage or disabling it doesn't solve your problem with dishwasher buttons not working, call a professional.

3. Temporary Software Glitch

Yes, it's annoying when an IT professional asks if you've tried turning your computer off and then back on again, but it's often the easiest way to fix a tech issue. The same rule applies to dishwasher troubleshooting. Power outages and surges can confuse the microcontroller responsible for responding to sensor data.

If you suspect a software glitch, turn the power to your dishwasher off at the circuit breaker. Leave it off for several minutes to give the system time to reset. Once you restore the power, try pressing the buttons again. If they work, you're done. Otherwise, call an appliance repair expert.

4. Misaligned Door or Broken Latch

A dishwasher latch is kind of like Goldilocks. It has to be closed just right for the dishwasher to work properly. Otherwise, the unit may go on strike, refusing to respond to your input no matter how hard you push the buttons. The easiest fix is to open the door, close it firmly and listen for the sound of the latch engaging. We also recommend checking for any obstructions, such as a wayward spatula, preventing the door from closing completely.

In some cases, the latch won't engage because it's damaged. This is one of those times when you need to consult a professional. Replacing a damaged latch requires the precision of a trained technician.

5. Faulty Ribbon Cable

The ribbon cable is a flat, thin cable that connects a dishwasher's touchpad to the electronic control board. If your dishwasher buttons don't work, it's possible the ribbon cable is loose or damaged. This can happen due to the constant heat and vibrations produced by a dishwasher. Addressing a faulty ribbon cable isn't a do-it-yourself issue; you need a professional with experience handling delicate electronics.

6. Bad Touchpad

Your dishwasher touchpad, also known as the control panel, can wear out over time. At first, you may have intermittent issues with one or two buttons. Eventually, the entire touchpad stops working, preventing you from using your dishwasher. You can't replace individual buttons, so have a technician replace the faulty touchpad.

7. Main Control Board Failure

The main control board acts like your dishwasher's brain. When you push a button, this board sends commands to other components, allowing you to change the water temperature, select a cycle and perform other functions. If you suspect a problem with the main control board, the first step is to restart your dishwasher. If this doesn't work, look for an error code that tells you what's happening.

Control board failure isn't a problem you can fix on your own. You need a technician with experience performing electrical testing and choosing the right replacement parts. Hiring a professional enhances safety and ensures your new control board is installed correctly.
