Overview of LG Dishwasher Components
LG dishwashers comprise numerous parts that work collectively to clean dishes effectively. These components can be broadly categorized into functional groups, such as water supply parts, drainage components, internal wash mechanisms, control systems, and exterior parts.
Major LG Dishwasher Parts and Their Functions
1. Water Inlet Valve
The water inlet valve controls the flow of water from your home's supply line into the dishwasher. It opens during the fill cycle to allow water in and closes once the desired water level is reached.
- Common issues: Valve failure can cause inadequate filling or continuous water flow.
- Replacement tips: Ensure the dishwasher is unplugged before replacing; inspect the valve for debris or damage.
2. Drain Pump
The drain pump removes dirty water from the dishwasher after the wash and rinse cycles.
- Common issues: Pump failure or clogs can lead to water pooling inside the dishwasher.
- Signs of failure: Dishwasher not draining, unusual noises during drain cycle.
- Replacement tips: Check for obstructions in the pump or hose before replacing.
3. Wash Pump
This pump circulates water through the spray arms during the wash cycle to clean dishes effectively.
- Common issues: Malfunction can lead to poor cleaning performance.
- Signs of failure: No water circulation or weak spray patterns.
4. Spray Arms
Spray arms distribute water throughout the dishwasher's interior during wash and rinse cycles.
- Types: Upper, lower, and sometimes middle spray arms.
- Common issues: Clogging due to mineral deposits or debris.
- Maintenance: Regular cleaning to keep spray holes clear.
5. Filters
Filters trap food particles and debris, preventing them from redepositing on dishes or clogging pumps.
- Types: Fine filters, coarse filters, and self-cleaning filters.
- Maintenance: Clean filters regularly to maintain performance.
6. Door Latch and Lock
These parts secure the door during operation and ensure safety by preventing water leakage.
- Common issues: Latch failure can prevent the dishwasher from starting.
- Signs: Door not locking or unlocking properly.
7. Control Panel and Electronic Components
Includes the display panel, control board, and touchpad, managing the dishwasher's functions.
- Common issues: Malfunctions or unresponsive controls due to electronic failure.
- Replacement: Usually involves replacing the entire control assembly.
8. Heating Element
Heats water during wash and dry cycles to improve cleaning and drying performance.
- Common issues: Element failure can result in incomplete washing or poor drying.
- Signs: No heat during cycles, or error codes related to heating.
9. Door Seal (Gasket)
A rubber gasket around the door ensures a watertight seal during operation.
- Common issues: Gasket damage or deterioration can cause leaks.
- Replacement: Regular inspection and timely replacement prevent water damage.
Additional Parts and Accessories
- Racks and Racking Components: Hold dishes securely during cycles.
- Detergent Dispenser: Releases detergent during the wash cycle.
- Float Switch and Assembly: Detects water level to prevent overfilling.
- Tub and Inner Components: The main body housing the internal parts and water pathways.
