LG Dishwasher Common Problems: Causes and Solutions
Welcome to our comprehensive guide on addressing common issues with your LG dishwasher. Remember, while many repairs are manageable for a handy homeowner, there’s no shame in calling a professional when needed.
LG Dishwasher Won’t Start
Common Causes
If your LG dishwasher won’t start, it could be due to a few common issues:
- Power Failure: Ensure the outlet is functioning and the circuit breaker hasn’t tripped.
- Door Latch Malfunction: The dishwasher may not detect the door being fully closed.
- Faulty Start Capacitor or Motor Coupler:
Step-by-Step Fix
- Check Power and Circuit Breaker: Reset the circuit breaker if tripped, or test the outlet with a voltage tester.
- Inspect Door Latch: Make sure the dishwasher door closes securely. Clean and lubricate the latch mechanism if needed.
- Test Start Capacitor/Motor Coupler: This step requires electrical knowledge. If uncertain, seek professional help as it involves handling live components.
