Check Power Supply
Check the Power Cable
The first step in troubleshooting a dishwasher that won’t start is to check the power cable. Make sure it is properly connected to the dishwasher and securely plugged into the power outlet. Sometimes, the power cable can become loose or disconnected, causing the dishwasher to lose power. By ensuring that the power cable is securely connected, you can rule out any issues related to power supply.
Test the Power Outlet
If you have confirmed that the power cable is securely connected, the next step is to test the power outlet. Plug another appliance into the same outlet to check if it is receiving power. If the other appliance is working fine, then the power outlet is not the issue. However, if the other appliance fails to work, there might be a problem with the power outlet itself. In this case, you may need to contact an electrician to resolve the issue.
Inspect the Electrical Panel
If the power outlet is functioning correctly, the next step is to inspect the electrical panel. Open the electrical panel and check if any circuit breakers have tripped. A tripped circuit breaker could be the reason why your dishwasher won’t start. If you find a tripped breaker, flip it back on to restore power to the dishwasher.
Ensure the Circuit Breaker is On
Even if you don’t see any tripped circuit breakers, it’s essential to ensure that the circuit breaker dedicated to your dishwasher is in the “On” position. Sometimes, circuit breakers can appear to be on, but they might have tripped slightly and need to be turned off and then back on again to reset. Flip the circuit breaker off and then back on to make sure it is fully engaged.
Examine Control Panel
Check for Error Codes or Lights
If the power supply is not the issue, the next step is to examine the control panel. Check for any error codes or lights on the dishwasher’s display. Error codes can provide valuable information about what might be causing the dishwasher to malfunction. Consult the manufacturer’s manual to decode the error codes and identify potential problems.
Inspect the Control Lock Feature
Some dishwashers have a control lock feature that can prevent the dishwasher from starting. This feature is designed to prevent accidental button presses or changes to the settings. Look for a control lock button or a specific combination of buttons that need to be pressed to unlock the control panel. If the control lock is engaged, follow the instructions in the manual to disable it.
Clean the Control Panel
A dirty or greasy control panel can sometimes cause issues with the dishwasher’s functionality. Use a soft cloth or sponge dampened with mild dish soap and warm water to clean the control panel. Be gentle and avoid using abrasive cleaners or scrub brushes that could damage the panel. Cleaning the control panel regularly can help prevent any buildup that could interfere with the proper functioning of the dishwasher.

Inspect Door Latch
Ensure the Door is Fully Closed
One common reason why a dishwasher might not start is if the door is not fully closed. Even a slightly open door can prevent the dishwasher from starting its cycle. Ensure that the door is completely closed and latched securely. If the door latch doesn’t seem to engage properly or feels loose, there may be an issue with the latch mechanism that needs to be addressed.
Check for Obstructions
Sometimes, debris or foreign objects can get lodged in the door latch, preventing it from closing properly. Inspect the latch area for any obstructions and gently remove them if found. It’s not uncommon for small utensils or pieces of food to accidentally fall into the latch area. Clearing any obstructions can often resolve the issue and allow the dishwasher to start.
Replace Broken Door Latch
If you have checked the door and latch area for any obstructions and everything seems fine, but the dishwasher still won’t start, there may be a problem with the door latch itself. Over time, door latches can wear out or break, preventing proper engagement. In this case, it may be necessary to replace the door latch. Contact the manufacturer or a dishwasher repair technician for assistance with replacing the door latch.
Verify Water Supply
Check the Water Valve
A dishwasher requires a proper water supply to function correctly. To check the water supply, start by ensuring that the water valve under the sink or behind the dishwasher is fully open. If the water valve is closed or only partially open, the dishwasher won’t be able to fill with water, resulting in it not starting. Turn the water valve all the way open and test the dishwasher again.
Inspect the Water Inlet Hose
Along with checking the water valve, it’s essential to inspect the water inlet hose connected to the dishwasher. Look for any kinks, twists, or damages in the hose that could be restricting water flow. If you spot any issues, straighten out the hose and ensure that it is properly connected. A damaged or improperly connected water inlet hose can prevent water from reaching the dishwasher, causing it not to start.
Clear any Blockages
In some cases, the water inlet hose or the dishwasher’s water inlet valve can become clogged with debris or mineral deposits. This can restrict the water flow and prevent the dishwasher from starting. Use a small brush or toothbrush to gently clean the water inlet hose and the inlet valve. Ensure that all blockages are cleared, and the water can flow freely. Once cleared, try running the dishwasher again to see if the issue is resolved.

Examine Drainage System
Clean the Drain Filter
A clogged or dirty drain filter can interfere with the dishwasher’s drainage system and prevent it from starting. Locate the drain filter, which is usually at the bottom of the dishwasher, and remove it. Rinse off any debris or food particles that may have accumulated on the filter. Cleaning the drain filter regularly will help maintain optimal drainage and ensure that the dishwasher starts without any issues.
Check the Drain Hose
After cleaning the drain filter, inspect the drain hose for any kinks, bends, or blockages. A blocked or clogged drain hose can hinder proper drainage, causing the dishwasher not to start. If you notice any issues with the drain hose, straighten out any kinks and remove any blockages. Ensure that the drain hose is properly connected to both the dishwasher and the drain system. Once the drain hose is clear and properly connected, try starting the dishwasher again.
Verify Proper Drainage
In addition to checking the drain filter and drain hose, it’s crucial to ensure that the dishwasher’s drain system is functioning correctly. Ensure that the drain line is properly attached to the garbage disposal or drainpipe and that there are no leaks. Test the drainage system by running the kitchen sink’s faucet and observing if water flows down the drain correctly. If the drainage system is not working properly, it may be necessary to seek professional help to diagnose and fix the issue.
Test the Door Switch
Check the Door Switch Contacts
The door switch plays a vital role in determining if the dishwasher can start. The door switch is a safety feature that prevents the dishwasher from running when the door is open. Locate the door switch and check its contacts to ensure they are clean and free of debris. If the contacts appear dirty, use a soft cloth or cotton swab dipped in rubbing alcohol to clean them. Ensure that the door switch is properly aligned with the door and that it depresses fully when the door is closed.
Measure the Continuity of the Door Switch
Using a multimeter, measure the continuity of the door switch to determine if it is functioning correctly. Set the multimeter to the appropriate setting and place one probe on each of the door switch’s terminals. With the door closed, the multimeter should read zero or very low resistance, indicating continuity. If the multimeter shows infinite resistance or no continuity, the door switch may need to be replaced. Consult the manufacturer’s manual or seek assistance from a dishwasher repair technician for further guidance.
