The convenience of owning a working dishwasher cannot be overstated. That’s why it can be such a nuisance when you discover that your dishwasher isn’t starting. Don’t worry though! Whether the fault lies with a defective door latch or a blown thermal fuse, our dishwasher troubleshooting guide will show you why your KitchenAid dishwasher won’t start.

Help! My KitchenAid Dishwasher Won’t Start!

If you’re asking, “Why won’t my KitchenAid dishwasher start?” the answer can be one of several common problems. While you could have a faulty part on your hands, it could be due to something as simple as not being properly plugged in. Take a few minutes to review these DIY tips prior to seeking repair.

Dishwasher Power Problem

Before digging too far into the case, check to see if your unit is receiving adequate power. Verify that the following power sources are in top power-providing shape:

  • Is your dishwasher properly plugged in? Avoid using extension cords as they’re not intended to transfer the power load that dishwashers require.
  • Are your power switches in the ON position? Check under the sink for the power switch if necessary.
  • Are there any tripped breakers on your home’s circuit breaker box? If needed, reset the tripped breakers.

If you’ve confirmed there is power and your dishwasher still won’t start, try a KitchenAid dishwasher reset sequence to clear out any issues. To perform a reset, disconnect your unit from the power source or flip the appropriate breaker for 1 minute before restoring the power source.

Problem with Dishwasher Settings

Today’s appliances, though seemingly simpler to operate, are more complex in order to deliver heightened convenience. You may think you’ve staged the proper settings, but doubling down couldn’t hurt. Check to see if any wash settings are preventing your unit from kicking off its wash regimen.

These settings can impede your dishwasher from immediately starting:

  • Delay Start: Appropriately named, this delays the start of your wash cycle to a predetermined later time. Press CANCEL/DRAIN to revoke the delay, followed by START/RESUME to see if the cycle starts.
  • Control Lock: This feature avoids unintended use of the dishwasher by locking all functions. To deactivate, press and hold the lock button for 4 seconds until the illuminated light above the button turns off.
  • Sleep Mode: An effort to conserve energy, this function turns off power to the dishwasher. To disable Sleep Mode, press START/RESUME or CANCEL, or open and close the door.

While fiddling with the settings, cement that no error codes are displayed or that your KitchenAid dishwasher control panel isn’t compromised. In the event you do confirm damage to the panel, a professional assessment might be required.

Dishwasher Door Is Not Latched Shut

Your KitchenAid dishwasher won’t start if the door isn’t securely fastened. When closing the door, make sure you close it with confidence. Once the door is completely shut and latched the dishwasher can start. If you’ve solidified that the door is fully shut and the dishwasher still won’t gas up, inspect the latch for damage. If the latch is compromised, get some professional eyes to examine whether or not the door needs replacement.

Dishwasher Water Supply Not Working

An instrumental step in KitchenAid dishwasher troubleshooting is checking to see if the issue can be chalked up as a water supply problem. Ensure the water supply line is accurately connected and the water valve is turned on. Dents or kinks in the water line can inhibit proper water flow from your home supply.

First, carefully smooth out any fractures in the hose. Next, verify the dishwasher’s water inlet valve is opening and closing normally since water can’t navigate to the dishwasher if the valve is caught in the closed position. If you’re in the presence of a faulty inlet valve, professional replacement is necessary.

Broken KitchenAid Dishwasher Parts

If your KitchenAid dishwasher won’t start after checking off the aforementioned tips, you might be faced with a defective part. Any of the following part malfunctions can contribute to your dishwasher dilemma:

  • Thermal Fuse: If the fuse is defective or if the dishwasher is at risk of overheating, the thermal fuse can blow. Perform a quick multimeter test to see if continuity is shown. If the multimeter test fails, you’re probably working with a blown fuse that needs to be replaced.
  • Main Control Board: The heart of your dishwasher, the main control board, sends voltage to the appropriate functions once it receives a signal from the control panel, which is the brain in this case. If the control board is defective it won’t supply the power required to start the dishwasher.
  • Timer: The timer, as with the control board, delegates the voltage to specific functions at specific times. If you have a malfunctioning timer, your unit may not receive adequate power to start.
