Though Viking dishwashers are synonymous with superior quality, starting issues common to all brands can prevent a wash cycle from the beginning. Why won’t my Viking dishwasher start? The control panel may be displaying the wrong setting or an error code. Determine why your Viking dishwasher won’t start with these common problems and solutions.
Troubleshooting When Your Viking Dishwasher Won’t Start
While the possibilities may seem endless, there are really several likely causes when your Viking dishwasher won’t start. From power issues to part failures, these Viking dishwasher troubleshooting tips can narrow down the problem.
1- Incoming Power Problem
In many cases, a Viking dishwasher not starting is attributable to an outside power problem. If the dishwasher isn’t receiving adequate electrical power, it won’t be able to turn on.
The following power problems can prevent a dishwasher from starting:
- Electrical cord isn’t plugged in: Make sure the dishwasher’s electrical cord is fully plugged into a functioning outlet. Avoid using extension cords; they can’t transmit the voltage the dishwasher requires, creating surges that interrupt power.
- Power switch is off: Many dishwashers are connected to a kitchen switch that must be on for it to receive power. Some switches are located in a cabinet under the kitchen sink and can be accidentally turned off when other items are moved around. Make sure the dishwasher’s corresponding switch is on so it receives power.
- Tripped circuit breaker: Check your home’s circuit breaker box for tripped breakers, repositioning any if necessary.

After a power interruption, your dishwasher may need to be reset to resume function. Most can be reset by pressing and holding the Start button for 4 seconds.
2- Need to Adjust Dishwasher Settings
Your Viking dishwasher won’t start if a cycle isn’t selected before pressing the Start button. After loading the dishwasher, select a cycle on the control panel, press “Start”, and shut the door. Even if you think the right setting is selected, check the control panel to make sure it shows the correct cycle and is error-free.
The following control panel issues can prevent the dishwasher from starting:
- Delay Start function: When the Delay Start setting is selected, it prevents an immediate start by delaying it to a later time. If the Delay Start button is illuminated, the setting has been activated. To turn it off, press and hold the Start button for 4 seconds.
- Error codes: These number and letter combinations alert you to various problems, some of which could prevent an immediate start. Consult your Viking dishwasher manual to determine the meaning of the code and how to solve the problem.
- Control panel malfunction: If you find your Viking dishwasher Start button not working or other buttons not responding, the control panel may have malfunctioned. When this happens, it must be professionally replaced.

3- Dishwasher Door Not Latching Shut
Like most dishwashers, a Viking dishwasher won’t start if the door isn’t completely shut and latched. After selecting a cycle and pressing the Start button, close the door firmly and make sure the latch is engaged.
A broken latch can prevent the dishwasher from starting even if the door is completely closed. If the latch fails electronically, it won’t signal the dishwasher to begin a wash cycle. A mechanical failure won’t keep the door securely closed. When the latch fails multimeter testing with no continuity or shows visible damage, it requires professional replacement.
4- Dishwasher Water Supply Malfunction
If your dishwasher has power but still won’t start on command it may have an inadequate water supply. Without consistent access to water, the dishwasher won’t be able to fill and start a cycle.
Make sure the dishwasher’s connection to your home water supply is turned on and properly secured. Also check the water inlet valve to make sure it allows water to enter the dishwasher from your home supply. If the valve is stuck in the closed position or doesn’t respond to electrical signals, water won’t flow to the dishwasher. In this case, the valve must be professionally replaced.
5- Defective Viking Dishwasher Parts
If the above troubleshooting tips don’t fix the problem, it’s possible a defective part is preventing the dishwasher from starting.
The following part failures should be addressed by a professional dishwasher repair service:
- Timer: The timer provides voltage to specific dishwasher functions at the appropriate times. If it fails, it may not signal the dishwasher to start, rinse or drain at the right points in the wash cycle.
- Main control board: This computerized board responds to control panel commands, sending electronic signals to the appropriate dishwasher function. A control board failure won’t respond to control panel settings or relay the command to start.
- Thermal fuse: A dishwasher’s thermal fuse blows if it’s in danger of overheating. While it won’t resume function until the fuse is replaced, the cause for overheating should be addressed or the fuse will blow again.
