If your dishwasher isn’t turning on, don’t panic. There are several simple troubleshooting steps you can take before calling in the professionals. Let’s walk through some common issues and solutions to get your appliance working again.
The first thing to check is the power supply. Make sure the dishwasher is properly plugged in and that the circuit breaker hasn’t tripped. It’s also worth checking if the door latch is engaged and the child lock feature is not activated. Sometimes, interrupting the wash cycle can cause the dishwasher to malfunction, so we’ll explore how to reset it as well. If all else fails, there may be some faulty components that need further attention.
Now, let’s dive into the details and get your dishwasher back up and running!
Key Takeaways:
- Check the power supply, including the circuit breaker and plug.
- Ensure that the door latch is engaged and the child lock isn’t activated.
- Try resetting the dishwasher if you’ve interrupted the wash cycle.
- If the issue persists, there may be faulty components that require testing and potential replacement.
- Consider calling a professional appliance repair technician if you’re unsure or unable to fix the problem yourself. You may also want to consider a home warranty to cover potential repair costs.
Checking the Power Supply
If your dishwasher won’t start, the first step in troubleshooting is to check the power supply. A faulty power connection can prevent the dishwasher from powering on. Follow these steps to ensure the power supply is properly functioning:
- Check the circuit breaker: Locate the circuit breaker panel in your home and check if the circuit controlling the dishwasher has tripped. If it has, flip the switch to the “off” position and then back on to reset it.
- Inspect the wall outlet: Ensure that the dishwasher is securely plugged into its designated wall outlet. Sometimes, the plug may become loose or disconnected, preventing power from reaching the appliance.
- Verify under-counter retainer clips: If your dishwasher is installed under the counter, there may be retainer clips holding it in place. Check if these clips need to be disconnected before you can access the power connection behind the appliance.
By taking these steps, you can troubleshoot and address any power supply issues that may be causing your dishwasher not to start.
Checking the Door Latch
If your dishwasher is not turning on, one of the possible causes could be a problem with the door latch. When the door latch is not engaged, a switch prevents the dishwasher from starting. To determine if the door latch is the issue, follow these steps:
- Listen for the sound of the latch clicking into place when you close the door. This indicates that the latch is properly engaged.
- Pull on the door gently to check if it is closed securely. A loose door may prevent the dishwasher from activating.
- Inspect the latch for any obstructions or broken parts that may prevent it from engaging properly. Clear away any debris or replace the latch if necessary.
If the door latch is broken, it may also affect the switch that allows the dishwasher to start. In this case, the latch and switch may both need to be replaced.
| Problem | Possible Cause | Solution |
|---|---|---|
| Dishwasher not turning on | Door latch not engaged | Check latch for proper engagement and replace if necessary |
Expert Tip:
“A simple check of the door latch can often solve the problem of a dishwasher not activating. Make sure to listen for the latch clicking into place and check for any visible issues with the latch. Keeping the door securely closed is crucial for the appliance to start.”
Deactivating the Child Lock
Many dishwashers have a child lock feature to prevent kids from opening the appliance or changing the cycle settings. In some cases, the unit will not run while the child lock is engaged. Refer to the manufacturer’s instructions to deactivate the child lock, usually by pressing and holding a button for a few seconds.
If your dishwasher won’t run and the door won’t open, checking the instructions for the child safety lock can help resolve the issue.
| Steps to Deactivate the Child Lock: | |
|---|---|
| 1. | Locate the child lock button on your dishwasher’s control panel. |
| 2. | Press and hold the child lock button for a few seconds. |
| 3. | Wait for the child lock indicator light to turn off. |
| 4. | Try running the dishwasher again to see if it responds. |
If the child lock feature was preventing your dishwasher from functioning, deactivating it should allow normal operation. However, if the issue persists, further troubleshooting or professional assistance may be required.
Resetting the Dishwasher
If you’ve interrupted the wash cycle and now the dishwasher won’t restart, it could be stuck between cycles. Try turning the power off and back on. If that doesn’t work, consult the manufacturer’s instructions for resetting the dishwasher. This may involve pressing and holding the start button or unplugging the machine for a short period of time. After resetting, you should be able to start a new wash cycle.

Timer Switch
The timer switch controls the various cycles and durations of the dishwasher. If the dishwasher is not turning on, the timer switch could be faulty. Test the switch using a multimeter and compare the readings to the manufacturer’s recommendations.
Selector Switches
Selectors switches determine the wash cycle settings for each load. If these switches are not working correctly, it can prevent the dishwasher from starting. Remove the switch from the control panel and test each button individually using a multimeter. Replace the selector switch if the readings deviate from the expected values.
Motor Start Relay and Thermal Fuse
The motor start relay and thermal fuse are two critical components that can cause the dishwasher not to start. Test these parts using a multimeter according to the instructions provided for your specific dishwasher model. Replace the motor start relay or thermal fuse if the readings differ from the expected values.
Remember to always observe proper safety measures and disconnect the power source before working on the dishwasher’s internal components.
“Proper testing of internal dishwasher components is essential to identify and resolve the issue of a dishwasher not turning on.”
By performing these tests, you can determine the faulty internal components that may be causing your dishwasher not to start. With this information, you can proceed to replace the necessary parts or seek professional assistance if needed.
