How to Fix LG QuadWash Not Draining
Your LG QuadWash dishwasher should simplify your life by efficiently washing and drying your dishes. However, when it fails to drain properly, it can turn into a frustrating problem. This guide will walk you through common causes of the issue and provide step-by-step solutions. Let’s dive in!
Understanding Dishwasher Drainage
Dishwashers use a drain pump to remove dirty water after each cycle. Various factors can prevent the pump from functioning correctly, leading to standing water in your dishwasher. In this article, we’ll explore common causes and practical solutions for resolving LG QuadWash not draining issues.
Common Causes of LG QuadWash Not Draining
1. Clogged Filter or Garbage Disposal
The dishwasher’s garbage disposal or drain hose may become clogged with food particles, debris, or small objects like utensils. This obstruction prevents the pump from expelling water effectively.
2. Faulty Drain Pump
Over time, the dishwasher’s drain pump motor can wear out, leading to malfunction and inability to remove water from your dishwasher.
3. Airgap Issues
An air gap is a small opening that equalizes pressure between the dishwasher’s drain hose and the sink. If it gets clogged or disconnected, it can prevent water from draining.
4. Blocked Drain Hose
The flexible plastic tube connecting your dishwasher to the sink (drain hose) may become kinked or twisted, restricting water flow and causing drainage problems.
Step-by-Step Fix Instructions
1. Check the Dishwasher Filter
- Turn off the dishwasher: Make sure your dishwasher is unplugged from the power source for safety.
- Access the filter: Open the dishwasher’s bottom dish rack, locate the filter cover (usually at the bottom front), and remove it.
- Inspect and clean the filter: Remove any food particles or debris from the filter. Rinse with water if necessary.
Affresh Dishwasher Cleaner (6 Tablets)
Brand: Affresh
This addresses Cause #1 above — “Clogged Filter or Garbage Disposal”. These tablets are made to break down the residue and build-up that collects inside the pump, tub and hoses — the obstruction described in that section. Rated by the manufacturer as safe for all dishwashers, all makes and models, so there is no model number to look up.
Be clear on what this is: a cleaner, not a repair part. If your drain pump has actually failed (Cause #2 above), a cleaner will not fix it — that needs the pump replaced.
2. Inspect and Clean the Garbage Disposal (if applicable)
- Turn off power to the garbage disposal: Locate the switch under the sink and flip it off.
- Access the disposal: Insert an octopus or wrench into the gap beneath the sink to turn the disposal’s grinding mechanism clockwise until it stops.
- Check for blockages: Use a flashlight and probe with a broom handle or long wooden stick to remove any obstructions. If you can’t clear the blockage, consider calling a plumber.
3. Examine the Airgap (if applicable)
- Locate the air gap: It’s typically found on your kitchen countertop near the sink.
- Remove and clean the air gap: Disassemble it, clear any debris, and reassemble. If this doesn’t work, you may need to replace the airgap.
4. Inspect the Drain Hose
- Unplug your dishwasher: Always disconnect power for safety.
- Remove the drain hose: Disconnect it from both the dishwasher and sink.
- Check for kinks or blockages: Straighten any bends in the hose, and ensure it’s free of debris.
5. Test the Drain Pump
If you suspect a faulty drain pump, you’ll need to test it using a multimeter or call a professional for assistance.
When to Call a Professional
If you’ve followed these steps and your LG QuadWash still isn’t draining correctly, it’s time to contact a qualified appliance repair technician. They can diagnose complex issues like a malfunctioning drain pump or electrical problems.
Prevention Tips
- Regular cleaning: Regularly clean the filter and run a garbage disposal cleaning cycle if applicable.
- Avoid putting large items in the dishwasher: Small utensils, food scraps, or other debris can clog the drain hose.
- Check air gaps periodically: Make sure they are clear and properly connected.
