Why Is My LG Dishwasher Not Starting

In the hustle and bustle of daily life, a malfunctioning dishwasher can throw a wrench into your routine. If you’re staring at your LG dishwasher in confusion, wondering why it’s not starting, you’re not alone. Let’s dive into some common issues and practical solutions to get your dishwasher back on track.

Why Is My LG Dishwasher Not Starting?

LG dishwashers are renowned for their efficiency and reliability, but like any appliance, they can face hiccups. The frustration of pressing the start button and nothing happening is all too familiar. Before you give in to the urge to call for professional help, let’s explore some DIY troubleshooting steps.

Power Supply Check

The first rule of thumb when dealing with any appliance glitch is to check the power supply. Ensure that your dishwasher is plugged in properly and that there are no issues with the electrical outlet. Additionally, take a moment to inspect your home’s circuit breakers for any tripped switches that might be affecting the power supply to the dishwasher.

Door Latch Issues

A seemingly insignificant problem like a poorly closed or latched door can prevent your dishwasher from starting. The door latch plays a crucial role in signaling to the appliance that it’s safe to commence the cleaning process. Check if there are any obstructions preventing the door from closing properly and troubleshoot latch issues accordingly.

Control Panel Malfunctions

The control panel is the nerve center of your LG dishwasher. If it’s malfunctioning, the entire system can be thrown off balance. Take a moment to understand the buttons and settings on the control panel. If you notice any unresponsiveness, follow the user manual’s guidelines for troubleshooting or consider seeking professional help.

Water Supply Problems

Adequate water supply is essential for your dishwasher to function seamlessly. Ensure that the water inlet valve is open, and the supply line is free of any kinks or blockages. Low water pressure can also affect the dishwasher’s ability to start, so address any issues with water pressure promptly.

Faulty Door Switch

The door switch is a safety feature that prevents the dishwasher from starting if the door is not securely closed. If the door switch malfunctions, the dishwasher may not initiate the cleaning cycle. Check the condition of the door switch and replace it if necessary.

Sensor and Timer Concerns

Sensors and timers play a crucial role in determining the duration and stages of the dishwasher cycle. If these components encounter issues, the dishwasher may fail to start. Take the time to understand the role of sensors and timers, and follow the manufacturer’s guidelines for troubleshooting.

Drainage Problems

A clogged or malfunctioning drainage system can hinder the dishwasher’s ability to start. Ensure that the drainage path is clear of debris and inspect the dishwasher’s filter for any blockages. Regularly cleaning the drainage system can prevent future starting issues.

Software Updates

In our technologically advanced world, even dishwashers receive software updates. Outdated software can lead to operational glitches. Check if your LG dishwasher has the latest software version by consulting the user manual and follow the instructions for updating the software.

Maintenance Tips

Prevention is often the best cure. Regular maintenance of your LG dishwasher can go a long way in preventing starting issues. Clean the interior, check for leaks, and inspect hoses and connections periodically. Following the manufacturer’s maintenance guidelines can extend the lifespan of your dishwasher.

Customer Support

If DIY troubleshooting doesn’t resolve the issue, don’t hesitate to reach out to LG’s customer support. They are equipped to provide assistance and may offer solutions tailored to your specific situation. Keep your dishwasher model number and details handy when contacting customer support.

DIY Solutions

Many dishwasher issues can be resolved with a bit of DIY effort. However, it’s essential to exercise caution and refrain from attempting complex repairs if you’re not confident. Some problems may require professional intervention to avoid further damage.

Professional Repair Services

When all else fails, it’s time to consider professional repair services. Research and choose a reputable appliance repair service with experience in handling LG dishwashers. Professional technicians have the expertise to diagnose and address complex issues effectively.

User Manual Reference

The user manual that came with your LG dishwasher is a valuable resource. It contains specific guidelines for troubleshooting and maintaining your appliance. Refer to the manual for detailed information on your dishwasher’s features and how to address common problems.


In the quest to revive your non-starting LG dishwasher, don’t forget the basics. From power supply checks to user manual references, each step can bring you closer to a solution. Experiment with DIY troubleshooting, but know when it’s time to seek professional help. A little patience and persistence can often save you from the inconvenience of a malfunctioning dishwasher.
