Check the Power Supply
Check the Power Outlet
The first step in troubleshooting a dishwasher that is not starting is to check the power outlet. Make sure that the outlet is functioning correctly by plugging in another appliance or device to see if it works. If the other appliance works, then the power outlet is not the issue. However, if the other appliance does not work, then you may need to check the circuit breaker or fuse box to ensure that there is power to the outlet. Resetting the breaker or replacing a blown fuse could solve the issue.
Inspect the Power Cord
After confirming that the power outlet is functioning correctly, the next step is to inspect the power cord of the dishwasher. Check for any visible damage to the cord, such as fraying or cuts. If you notice any damage, it is important to replace the power cord to avoid any potential safety hazards. Additionally, make sure that the power cord is securely plugged into the dishwasher, as a loose connection could prevent the appliance from starting.
Test the Outlet with Another Appliance
If the power outlet and power cord appear to be in good condition, but the dishwasher is still not starting, it is recommended to test the outlet with another appliance. Plug in a different appliance, such as a lamp or phone charger, and see if it works. If the second appliance works in the same outlet, then the issue lies with the dishwasher. However, if the second appliance also does not work, then the problem might be with the outlet itself or the electrical wiring in your home. In this case, it is advisable to call a professional electrician to investigate and resolve the issue.
Verify the Control Settings
Check the Control Lock
Sometimes, a dishwasher may not start due to the control lock feature being enabled. This feature is designed to prevent accidental button presses and can be easily activated or deactivated by pressing a specific button or combination of buttons on the control panel. Refer to the dishwasher’s user manual to identify the control lock button or combination and ensure that it is not engaged. Disabling the control lock should allow you to start the dishwasher.
Examine the Timer/Delay Start
Another reason why your dishwasher may not be starting is if the timer or delay start feature is active. Check the control panel for any indication of a timer or delay start setting. If the dishwasher is set to start at a specific time, it will not initiate a cycle until that time is reached. Adjust the timer or disable the delay start feature if necessary, and try starting the dishwasher again.
Inspect the Cycle Selection
Ensure that you have selected a specific cycle for the dishwasher to run. Some dishwashers have multiple cycle options, such as “Normal,” “Heavy,” or “Quick Wash.” If no cycle is selected, the dishwasher will not start. Carefully review the available cycle options and press the appropriate button for the desired cycle. Once a cycle is selected, the dishwasher should initiate the chosen cycle and begin operating.

Ensure Proper Door Closure
Check for Door Misalignment
A common reason why a dishwasher may not start is due to misalignment of the door. When the door is not properly aligned and securely closed, the dishwasher’s safety mechanism may prevent it from starting. Inspect the door for any signs of misalignment, such as gaps or protrusion. If misalignment is detected, you may need to adjust the hinges or latch mechanism to ensure that the door closes tightly. Once the door is properly aligned, the dishwasher should start as expected.
Inspect the Door Latch
The door latch is a crucial component that ensures the dishwasher door remains closed during operation. If the door latch is damaged or not functioning correctly, it can prevent the dishwasher from starting. Take a close look at the door latch mechanism and check for any signs of damage or wear. If you notice any issues, such as a broken latch or a loose fitting, you may need to replace the latch to enable proper door closure and allow the dishwasher to start.
Clean the Door Gasket
The door gasket, also known as the door seal, plays a vital role in creating a watertight seal when the dishwasher is in use. Over time, the door gasket can accumulate dirt, debris, and residue, which can prevent the door from closing properly. Inspect the door gasket and clean it thoroughly using a damp cloth or mild detergent. Be sure to remove any debris or buildup along the gasket’s entire length. Once the gasket is clean, close the door and attempt to start the dishwasher again.
Examine the Water Supply
Check the Water Tap
In order for a dishwasher to operate, it requires a sufficient water supply. Ensure that the water tap, which supplies water to the dishwasher, is fully turned on. Sometimes, the tap may accidentally be left partially closed or in the “off” position, preventing water from reaching the dishwasher. Verify that the water tap is completely open and try starting the dishwasher once more.
Inspect the Inlet Valve
The inlet valve controls the flow of water into the dishwasher. If the inlet valve is clogged or not functioning properly, it can hinder the dishwasher’s ability to start. Locate the inlet valve, typically found behind the lower access panel or beneath the dishwasher itself. Inspect the valve for any signs of damage or clogs. If necessary, clean the inlet valve or replace it entirely to restore proper water flow and enable the dishwasher to start.
Clean the Filter Screen
Dishwashers are equipped with a filter screen that traps debris and prevents it from clogging the internal components. Over time, this filter screen can become clogged itself, restricting the water flow and preventing the dishwasher from starting. Find and remove the filter screen, usually located at the bottom of the dishwasher, and clean it thoroughly. Make sure to remove any trapped debris or residue. Once the filter screen is clean and free of obstructions, reinstall it and attempt to start the dishwasher.
