Common questions about LG dishwasher failure

Comprehensive Guide to Common LG Dishwasher Problems and Solutions

LG dishwashers are known for their reliability and advanced features, but like any appliance, they can experience issues over time. This guide addresses the most common questions and concerns related to LG dishwasher malfunctions, providing detailed explanations and troubleshooting tips.

Why is my LG dishwasher not starting?

Answer: If your LG dishwasher won’t start, it could be due to several factors:

• Door latch issues: Ensure that the door is properly closed and latched. If the door latch is faulty, the dishwasher won’t start.
• Power supply problems: Check the power cord, circuit breaker, and ensure the dishwasher is properly plugged in. A tripped circuit breaker or a blown fuse can prevent the dishwasher from starting.
• Control panel malfunction: If the control panel is unresponsive or shows an error, it could indicate an electronic failure. Resetting the dishwasher by unplugging it for a few minutes can sometimes resolve this issue.

Why is my LG dishwasher not draining?

Answer: When an LG dishwasher fails to drain, the most common causes are:

• Clogged drain filter: The drain filter traps debris and food particles. If it’s clogged, water won’t drain properly. Clean the filter regularly to avoid this issue.
• Blocked drain hose: The drain hose may be kinked or obstructed. Check for any blockages and ensure the hose is correctly positioned.
• Faulty drain pump: If the drain pump is defective, it won’t be able to expel water from the dishwasher. A faulty pump may need to be replaced.

Why is my LG dishwasher leaking water?

Answer: Water leaks in an LG dishwasher can occur due to:

• Damaged door gasket: The door gasket seals the door to prevent water from leaking. If it’s damaged or worn out, water may escape during the wash cycle. Replace the gasket if necessary.
• Overloaded dishwasher: Overloading the dishwasher can cause water to spill out. Make sure you’re not exceeding the recommended capacity.
• Loose or damaged hoses: Check the water inlet and drain hoses for any leaks or loose connections.

Why is my LG dishwasher making loud noises?

Answer: Unusual noises in your LG dishwasher could be due to:
