Are you frustrated when you press start on your dishwasher, only to be met with silence? You’re not alone. A non-responsive dishwasher can be a major inconvenience, especially when you’re relying on it to get your dishes clean. In this article, we’ll dive into the common causes of a dishwasher that won’t start and provide you with troubleshooting steps to get your appliance up and running again.
Checking the Obvious: Power and Water Supply
Before we delve into more complex issues, let’s start with the basics. Ensure that your dishwasher is receiving power and water supply. Check the following:
- Is the dishwasher properly plugged into a working outlet?
- Is the circuit breaker or fuse controlling the outlet tripped or blown?
- Is the water supply valve behind the dishwasher turned on?
- Are the water hoses kinked or clogged, restricting water flow?
Verify that the dishwasher is receiving power by checking the control panel for lights or sounds.
Troubleshooting Common Issues
Now that we’ve ruled out the obvious, let’s explore some common issues that might be causing your dishwasher to malfunction.
The Faulty Door Latch
A faulty door latch is a common culprit when it comes to dishwashers that won’t start. The door latch ensures the dishwasher door is securely closed during the cycle. If the latch is malfunctioning, the dishwasher won’t start. Check the door latch for any signs of wear or damage. You can try cleaning the latch or replacing it if necessary.
The Faulty Timer or Control Board
The timer or control board is the brain of your dishwasher, responsible for governing the cycles and functions. If the timer or control board is faulty, the dishwasher won’t start. Check for signs of physical damage, corrosion, or burn marks on the board. If you suspect the timer or control board is the issue, it’s recommended to consult a professional appliance technician.
The Faulty Thermal Overload Protector
Some dishwashers come equipped with a thermal overload protector, a safety feature designed to prevent overheating. If the protector is tripped, the dishwasher won’t start. Check your user manual to see if your model has this feature and how to reset it.
Leaks and Water Accumulation
Leaks or water accumulation in the dishwasher can prevent it from starting. Check the dishwasher floor and surrounding areas for signs of water damage or leaks. Ensure the dishwasher is properly leveled and the door seal is intact.
The Faulty Water Inlet Valve
The water inlet valve supplies water to the dishwasher. If the valve is clogged or faulty, the dishwasher won’t start. Check the valve for mineral buildup or debris. Clean or replace the valve as necessary.
Clogged Filters and Spray Arms
Clogged filters and spray arms can reduce water pressure, preventing the dishwasher from starting. Check and clean the filters and spray arms according to your user manual’s instructions.
Checking the Detergent Dispenser
A clogged detergent dispenser can also prevent the dishwasher from starting. Check the dispenser and clean it out if necessary.
Error Codes and Diagnostic Cycles
Many modern dishwashers come equipped with error codes and diagnostic cycles to help troubleshoot issues. Check your user manual to see if your model has this feature. Error codes can provide valuable information about the problem, allowing you to take corrective action.
Consult your user manual to see if your dishwasher has a diagnostic cycle or error code feature.
When to Call a Professional
If you’ve tried the troubleshooting steps above and your dishwasher still won’t start, it may be time to call a professional appliance technician. They can diagnose the issue and provide a quote for repairs. In some cases, it may be more cost-effective to replace the dishwasher, especially if it’s an older model.
Preventative Maintenance
To minimize the risk of your dishwasher breaking down, perform regular maintenance tasks such as:
- Cleaning the filters and spray arms
- Checking and replacing worn-out parts
- Ensuring proper installation and leveling
- Running cleaning cycles or diagnostic tests as recommended by the manufacturer
By performing regular maintenance, you can extend the lifespan of your dishwasher and reduce the likelihood of breakdowns.

What should I do first when my dishwasher doesn’t start?
When your dishwasher doesn’t start, the first thing you should do is check the power supply. Make sure the dishwasher is properly plugged into a working outlet and that the outlet is not controlled by a switch that might have been turned off. Additionally, check your circuit breaker or fuse box to ensure that the breaker hasn’t tripped or a fuse hasn’t blown.
If you’ve checked the power supply and everything seems to be in order, then it’s time to move on to the next possible cause. Check the dishwasher’s control panel for any error codes or lights that might indicate what’s preventing it from starting. Consult your user manual if you’re not familiar with the control panel or the error codes it displays.
Is it possible that a faulty door latch is preventing my dishwasher from starting?
Yes, it’s entirely possible that a faulty door latch is the culprit. The door latch is a safety mechanism that prevents the dishwasher from running when the door is open. If the latch is faulty, the dishwasher might not start even when the door is closed. Inspect the latch and the surrounding area for any signs of damage, blockages, or misalignment.
To troubleshoot the door latch, try opening and closing the door a few times to see if it’s properly engaging. You can also try cleaning the latch and the surrounding area to remove any debris or food particles that might be preventing it from functioning correctly. If you’re still unsure, it might be a good idea to consult a professional appliance repair technician for further assistance.
Could a faulty timer or thermostat be preventing my dishwasher from starting?
Yes, a faulty timer or thermostat could be preventing your dishwasher from starting. The timer controls the cycle duration, and the thermostat regulates the water temperature. If either of these components fails, the dishwasher might not start. Check your user manual to see if it provides troubleshooting steps for these components or if it recommends any specific error codes to look out for.
If you suspect that the timer or thermostat is faulty, it’s a good idea to consult a professional appliance repair technician. They will have the necessary expertise and tools to diagnose and replace the faulty component. Remember, attempting to repair or replace these components yourself can be dangerous and might cause further damage to your dishwasher.
What if I’ve checked everything and my dishwasher still won’t start?
If you’ve checked the power supply, door latch, and timer/thermostat, and your dishwasher still won’t start, it’s possible that the problem is more complex and requires professional attention. At this point, it’s a good idea to call a licensed appliance repair technician to diagnose and repair the issue.
The technician will have the necessary expertise and tools to diagnose the problem and provide a quote for the repairs. Be prepared to provide them with as much information as possible about the issue, including any error codes you’ve encountered or unusual sounds or smells you’ve noticed.
How can I prevent my dishwasher from breaking down in the future?
To prevent your dishwasher from breaking down in the future, make sure to follow the recommended maintenance schedule outlined in your user manual. This typically includes cleaning the filters, checking and replacing worn-out parts, and running cleaning cycles to remove grease and food residue.
Additionally, make sure to load the dishwasher correctly to avoid blockages and damage to the internal components. Scrape off large food particles from dishes before loading them, and avoid overcrowding the racks. By following these simple tips, you can help extend the lifespan of your dishwasher and prevent costly repairs.
Can I repair my dishwasher myself, or do I need to call a professional?
While some minor issues with your dishwasher might be repairable yourself, it’s generally recommended to call a professional appliance repair technician for anything beyond simple troubleshooting. Dishwashers contain complex electrical and mechanical components that require specialized tools and expertise to repair safely and correctly.
Attempting to repair your dishwasher yourself can lead to further damage, electrical shock, or even fire hazards. A licensed appliance repair technician has the necessary training, experience, and tools to diagnose and repair the issue quickly and safely.
How much does it cost to repair a dishwasher that won’t start?
The cost to repair a dishwasher that won’t start can vary widely depending on the cause of the problem and the extent of the repairs needed. If the issue is a simple one, such as a faulty door latch or a tripped circuit breaker, the repair cost might be relatively low.
However, if the problem is more complex, such as a faulty control board or a broken motor, the repair cost could be higher. On average, the cost of repairing a dishwasher can range from $100 to $500 or more, depending on the type and complexity of the repair. Be sure to get a quote from a licensed appliance repair technician before proceeding with any repairs.
