Common LG Dishwasher Problems
While LG dishwashers are known for their efficiency and reliability, they can still experience occasional problems. Here are some of the most common issues you might encounter:
1. Dishwasher Won't Start
If your LG dishwasher refuses to start, it can be due to several reasons:

If your dishwasher is not filling with water, consider the following:
