Is your dishwasher refusing to start just when you need it most? It’s frustrating, isn’t it?
You press the start button, but nothing happens. Before you panic or call a costly repair service, there are simple reasons why your dishwasher won’t start—and even easier fixes you can try yourself. From a door that’s not fully latched to settings like “Delay Start” or “Control Lock” accidentally turned on, the problem might be something quick to spot and solve.
Keep reading, and you’ll learn exactly what to check and how to get your dishwasher running again—without the stress or expense.
Check The Door Latch
The door latch is a key part that helps your dishwasher start. It keeps the door tightly closed during the wash cycle. If the latch is not working right, the dishwasher will not begin. Checking the door latch is a simple first step to fix this problem.
A door that is not fully closed or a latch that is broken can stop the dishwasher from starting. This section explains how to check the door latch and fix any issues.
Ensure Door Is Fully Closed
Open the dishwasher door. Close it firmly until you hear a click. The latch must catch and hold the door tight. If the door feels loose or does not stay closed, the latch might be the cause.
Sometimes, the door looks closed but is not latched properly. Press the door gently and try to start the dishwasher again. This often solves the problem quickly.
Fix A Faulty Latch
A broken or worn latch cannot keep the door closed. Inspect the latch for any damage or wear. Look for cracks or loose parts that stop it from working well.
Replace the latch if you find it damaged. New latches are easy to buy online or at appliance stores. Installing it usually requires just a screwdriver and a few minutes.
After fixing or replacing the latch, close the door firmly. Test the dishwasher to see if it starts. A good latch allows the dishwasher to run without issues.

Review Dishwasher Settings
Reviewing your dishwasher settings is essential when it won’t start. Settings like Delay Start, Control Lock, or Sleep Mode can prevent it from running. Checking these can save time and avoid unnecessary repairs.
Sometimes, the dishwasher appears off but is just waiting due to a setting. Understanding these controls helps you quickly identify the problem and fix it.
Deactivate Delay Start
The Delay Start feature pauses the dishwasher from starting immediately. This setting is useful for running the dishwasher later. Check your control panel for a Delay Start button or icon. Press it to cancel the delay and start the cycle right away.
If the dishwasher does not start after setting a wash cycle, Delay Start might be active. Deactivate it by holding or pressing the button until the delay time clears. This action allows the dishwasher to begin the cleaning process.
Turn Off Control Lock
The Control Lock prevents accidental changes to settings. It disables buttons on the control panel. Look for a lock symbol or a key icon on your dishwasher’s display. Press and hold the Control Lock button for several seconds to turn it off.
If Control Lock is on, the dishwasher won’t respond to commands. Turning it off restores normal function. This step is common and often overlooked when troubleshooting start issues.
Wake From Sleep Mode
Some dishwashers enter Sleep Mode to save power. In this mode, the display may go blank, and the machine seems off. Press any button like Start or Cancel to wake the dishwasher. Opening and closing the door can also help.
Sleep Mode stops the dishwasher from starting a cycle. Waking it up restores normal operation. If the dishwasher remains unresponsive, try pressing the buttons again or resetting the power.
Power Supply Troubleshooting
Power supply issues often cause dishwashers not to start. Checking the power source is a simple first step. It can save time and avoid unnecessary repairs. The dishwasher needs a steady power flow to operate. Troubleshooting the power supply is easy and quick.
Verify Plug And Outlet
Check if the dishwasher plug is fully inserted into the outlet. Sometimes the plug can be loose or partially unplugged. Make sure the outlet is working by testing it with another device, like a lamp or phone charger. If the outlet has no power, the problem is with the electrical source, not the dishwasher. Avoid using extension cords as they can cause power drops.
Reset Circuit Breaker
Locate your home’s circuit breaker panel. Find the breaker labeled for the dishwasher. Flip the breaker off and then back on to reset it. This step can restore power if the breaker has tripped. A tripped breaker cuts power to the dishwasher for safety. After resetting, try starting the dishwasher again. If the breaker trips repeatedly, call an electrician for help.

Inspect Water Supply
Checking the water supply is crucial when your dishwasher won’t start. Without water, the dishwasher cannot fill or begin its cycle. Problems with the water supply can cause the machine to stop working entirely. Take time to inspect all parts related to water flow. This step can often fix the issue quickly and save you a service call.
Check Water Valve
Locate the water valve usually found under the kitchen sink. Ensure the valve is fully open to allow water flow. Sometimes the valve may be partially closed or stuck. Turn the valve handle counterclockwise until it stops. If the valve is broken or leaking, it needs replacement. A closed or faulty valve cuts off water to the dishwasher.
Confirm Water Flow
After opening the valve, test if water flows properly. Turn on the faucet connected to the dishwasher supply line. Water should flow steadily without interruptions. If water flow is weak or absent, the supply line might be clogged or kinked. Clear any blockages or replace the hose if damaged. Without proper water flow, the dishwasher will not start its cycle.
Restart The Dishwasher Cycle
Restarting the dishwasher cycle can help solve many common start issues. Sometimes the machine needs a simple reset to begin working again. This process clears minor errors and ensures the dishwasher is ready to run. Follow the steps below to restart your dishwasher cycle correctly.
Press Start After Door Opens
When the dishwasher door opens during a cycle, the machine often pauses. Close the door firmly and press the Start button again. This action tells the dishwasher to resume the cleaning process. Make sure the door is fully closed to allow the dishwasher to start. If the Start button does not respond, try pressing it firmly or holding it for a couple of seconds.
Cancel And Restart Cycle
Canceling the current cycle can clear errors that stop the dishwasher from starting. Press the Cancel or Reset button to stop the dishwasher. Wait for a few minutes before starting a new cycle. This pause allows the machine to reset its controls. After waiting, select the desired cycle and press Start. This method often fixes issues caused by stuck commands or glitches.
Reset The Dishwasher Unit
Resetting the dishwasher unit can resolve many start-up issues quickly. It clears minor electrical glitches and restores normal function. This process involves cutting power to the dishwasher and restarting it. Resetting can fix unresponsive controls or error codes displayed on the panel.
Two common reset methods exist: power cycling via the breaker and performing a factory reset if the model supports it. Each method helps refresh the dishwasher’s internal system. Follow these steps carefully to avoid any damage or data loss.
Power Cycle Via Breaker
Locate your home’s circuit breaker panel. Find the breaker switch labeled for your dishwasher.
Flip the breaker to the OFF position. Wait for about 30 seconds to 1 minute.
Switch the breaker back ON. This action cuts power and restarts the dishwasher’s electronics.
After power restoration, try starting the dishwasher again. This simple step often clears temporary faults.
Factory Reset If Available
Check your dishwasher’s user manual for reset instructions. Not all models have a factory reset feature.
Usually, a combination of button presses on the control panel triggers this reset. This clears all settings and errors.
Follow the exact steps from the manual carefully. A factory reset returns the dishwasher to default settings.
After the reset, reprogram your preferred settings. Test the dishwasher to see if it starts properly now.
Troubleshoot Internal Components
Troubleshooting internal components helps find hidden issues inside your dishwasher. These parts control starting and running cycles. Checking them avoids costly repairs. Follow these steps to test key parts safely and effectively.
Always unplug the dishwasher before testing internal components. Use a multimeter to check electrical parts for continuity. Replace any faulty parts to restore function.
Test Door Latch Switch
The door latch switch signals the dishwasher to start when closed. If the switch is broken, the dishwasher won’t start. Open the dishwasher door and locate the latch switch near the door frame.
Use a multimeter to test the switch for continuity. Press the latch button and check if the meter shows a complete circuit. No continuity means the latch switch is faulty and needs replacement.
Check Control Board
The control board directs all dishwasher functions. Faulty boards can stop the dishwasher from starting. Look inside the dishwasher panel to find the control board.
Inspect the board for burned marks or damaged parts. Test for power using a multimeter. If the board shows no signs of life or damage, replace it to fix the problem.
Inspect Thermal Fuse
The thermal fuse protects the dishwasher from overheating. A blown fuse cuts power to the dishwasher, preventing it from starting. Locate the thermal fuse on or near the control board.
Use a multimeter to check the fuse for continuity. No continuity means the fuse is blown and must be replaced. This simple fix can restore dishwasher function quickly.

When To Call A Professional
Knowing when to call a professional is important for dishwasher issues. Some problems need expert tools and skills. Trying to fix these can cause more damage or risk safety. Recognizing the right moment to seek help saves time and money.
Signs Of Complex Issues
Persistent power problems may signal complex electrical faults. Strange noises like grinding or buzzing often mean motor or pump trouble. Water leaks under the dishwasher suggest seal or hose failures. Error codes on the display require specialized diagnosis. If the dishwasher door latch seems fine but it still won’t start, internal control board faults might be the cause. Multiple attempts to reset or start the dishwasher without success also indicate deeper issues.
Safety Considerations
Dishwashers use electricity and water, creating risks. Avoid fixing electrical parts if you lack experience. Water leaks can cause shocks or damage floors and cabinets. Gas or electric connections in some models need special handling. Unplug the appliance before attempting minor checks. Do not force stuck components or open the machine casing. Professionals have tools to safely test and repair internal parts. Calling an expert prevents injury and protects your home.
