If your LG dishwasher has suddenly gone dark, leaving you with a sink full of dirty dishes, you’re not alone. Power issues are a common problem with LG dishwashers, and they can be frustrating to troubleshoot. But fear not! This comprehensive guide will shed light on the potential causes of your dishwasher’s power outage and provide you with step-by-step solutions to restore its functionality.
Safety First: Unplug the Dishwasher
Before you begin troubleshooting, it’s crucial to unplug the dishwasher from the power outlet. This will prevent any electrical shocks or damage to the appliance.
Inspect the Power Cord and Outlet
The first step in troubleshooting is to check the power cord and outlet. Ensure that the cord is securely plugged into the outlet and that the outlet is turned on. If the cord or outlet is damaged, it may be necessary to replace them.
Reset the Circuit Breaker or Fuse
If the power cord and outlet are intact, the next step is to reset the circuit breaker or fuse that powers the dishwasher. Locate the electrical panel and identify the breaker or fuse that corresponds to the dishwasher. Flip the breaker to the “off” position and then back to the “on” position. If the fuse is blown, replace it with a fuse of the same amperage.
Check the Dishwasher Door
A malfunctioning door latch can prevent the dishwasher from receiving power. Open and close the dishwasher door several times to ensure that it latches securely. If the door does not close properly, it may need to be adjusted or replaced.
Inspect the Control Panel
The control panel is the brain of the dishwasher, and it can sometimes malfunction, causing a power outage. Check the control panel for any visible damage or loose wires. If you notice any issues, it may be necessary to replace the control panel.
Test the Thermal Fuse
The thermal fuse is a safety device that protects the dishwasher from overheating. If the thermal fuse has blown, it will need to be replaced. To test the thermal fuse, use a multimeter to check for continuity. If there is no continuity, the thermal fuse is blown.
Check the Main Control Board
The main control board is the central hub of the dishwasher, and it can sometimes fail, causing a power outage. If you have ruled out all other potential causes, it may be necessary to replace the main control board. This is a complex repair that should be performed by a qualified appliance technician.
