LG Dishwasher Keeps Turning Off: Troubleshooting Tips and Quick Fixes
If your LG dishwasher keeps turning off, you’re likely grappling with a common annoyance that can disrupt your kitchen routine. I remember wrangling with a similar issue not too long ago when mid-cycle shutdowns became the norm, and the solution involved a mix of checks and balances—from power sources to door latches.
Troubleshooting begins with a systematic approach to diagnose potential faults.
Start with the door latch because it’s a safety feature that, if not properly engaged, will prevent the dishwasher from running.

Additionally, inspect both the thermal and household fuses.
A blown fuse can cut power, whereas a thermal fuse is a fail-safe against overheating.
In my kitchen, a faulty thermal fuse was the culprit; replacing it got the dishwasher back in action.
Next, if the control panel seems unresponsive, it could indicate an electrical issue that may require resetting the dishwasher.
This can be as simple as turning off the appliance and flipping the circuit breaker connected to the dishwasher for at least ten seconds.
It’s a method I’ve employed when faced with unexplained appliance behavior, often leading to a swift resolution.
Remember that mechanical problems, like a seized motor, will need a professional touch, so if the basic diagnostic steps don’t yield results, it might be time to call in an expert.

Step-by-Step Troubleshooting Guide
When your LG dishwasher unexpectedly turns off, it can be quite the kitchen conundrum. Let’s go through the steps to bring calm to the chaos.

Resetting the Dishwasher
To give your dishwasher a fresh start, perform a simple reset:
- Power Down: Press the power button to turn the appliance off.
- Circuit Reset: Flip the circuit breaker connected to your dishwasher and wait at least 10 seconds before turning it back on.
- Power Up: Press the power button to turn on the dishwasher and start a new cycle.
Checking the Door Latch
A faulty door latch might be the culprit:
- Examine the Latch: Ensure that the door latch is engaging properly. If it’s not, the dishwasher will think the door is open and shut down to prevent leaks.
- Test the Door: Try closing your dishwasher door with extra firmness. If it still turns off, the latch may need repair or replacement.
Inspecting the Control Panel and Circuit Breaker
Electrical issues often lead to dishwasher disruptions:
- Control Panel: Look for any signs of malfunction, such as unresponsive buttons or unusual error codes displayed.
- Power Supply: Check if you have a blown fuse by inspecting your home’s fuse box for a tripped circuit breaker.
Issue | Action to Take |
---|---|
Non-responsive Panel | Consult the user manual for reset or contact support. |
Tripped Breaker | Reset the breaker or replace the fuse, if necessary. |

Regular Cleaning: Ensure you’re cleaning the dishwasher’s interior monthly to remove any food particles and residues.
Use a dishwasher-safe cleaner and run it on a hot cycle for thorough cleaning.
- Filter Maintenance: At least once a month, remove and clean the dishwasher’s filter. A clogged filter can lead to reduced efficiency and even cause your appliance to turn off unexpectedly.
