Frequently Asked Questions
Q: What should I do if the dishwasher is not draining?
A: If you notice standing water in the tub, start by checking for blockages:
- Clean the filter: Remove the bottom rack, then take out and rinse the filter under warm, soapy water to remove debris.
- Inspect the drain hose: Look behind the dishwasher to ensure the drain hose isn’t kinked or clogged. Check the air gap or garbage disposal connection for obstructions.
- Run a drain cycle: You can try initiating and then canceling a cycle to trigger draining, or use the LG ThinQ app's diagnostic tools if available.
Q: Why aren’t my dishes getting clean?
A: Poor cleaning may result from incorrect loading, detergent issues, or blocked spray arms:
- Load correctly: Avoid overloading and ensure items don’t block the spray arms or detergent dispenser.
- Check the spray arms: This model has three. Ensure they spin freely and clean any clogged spray holes.
- Use proper detergent: Use a high-quality dishwasher detergent, especially if you have hard water. A booster may help improve performance.
Q: What if the dishes are not drying completely?
A: Incomplete drying can be improved with these steps:
- Check rinse aid: Ensure the dispenser is full. Rinse aid helps reduce water spots and improves drying.
- Use the Dry Boost option: This raises the final rinse temperature for better drying.
- Allow airflow: Avoid crowding the racks—space between dishes helps air circulate during drying.
Q: What do the error codes mean on my dishwasher?
A: Here are some common LG dishwasher error codes and their meanings:
- IE (Inlet Error): Water isn't entering the unit. Ensure the supply valve is open and hoses aren't kinked. Low water pressure may also be an issue.
- OE (Outlet Error): The dishwasher can't drain, often due to a clogged filter or drain hose.
- E1 (Overflow Error): Too much water is in the tub. This could be caused by a faulty water inlet valve or float switch.
- LC (Leakage Error): Water has leaked to the base of the unit. Check for leaks in hoses or plumbing. Refer to the manual for sensor troubleshooting steps.
