Diagnosing Common PARTSTORE Dishwasher Problems

To keep your LG dishwasher running smoothly, it's important to identify and address common issues promptly. Here are some typical problems you might encounter and how to diagnose them:

Leaks

If you notice water pooling around your dishwasher, check these potential causes:

1. Door gasket: Look for tears, gaps, or cuts in the seal that could cause a leak.
2. Hose connections: Inspect and tighten all hose connections, including the 90-degree elbow joints.
3. Water inlet valve: A stuck-open valve can lead to overflow.
4. Wash arms: Cracked wash arms can spray water towards the door seal.

Poor Cleaning Performance

When dishes come out dirty, consider these factors:

1. Improper loading: Ensure dishes aren't overcrowded and are positioned correctly.
2. Spray arms: Check for clogs or obstructions in the spray arm holes.
3. Detergent usage: Use the right amount and type of detergent.
4. Water supply: Confirm adequate water pressure and temperature (around 120°F).

Unusual Noises

Different noises can indicate specific issues:

1. Rattling: Often due to loose items or an improperly secured filter.
2. Whistling: May occur when water is drawn in; adjust water pressure if too loud.
3. Growling: Could be air being pulled through to clean the filter.
4. Squealing or grinding: Might indicate a pump problem.

Drainage Issues

If your dishwasher isn't draining properly, consider these potential causes:

1. Clogged filter: Clean the filter regularly to prevent buildup.
2. Kinked drain hose: Ensure the hose isn't bent or obstructed.
3. Garbage disposal: If recently installed, check if the knockout plug has been removed.
4. Drain pump: A faulty pump may need replacement.

By identifying these common problems, you can often resolve issues without professional help, saving time and money.

Replacing the Water Inlet Valve

When your PARTSTORE dishwasher isn't cleaning properly, leaks, makes noise, overflows, or won't fill, the water inlet valve might be the culprit. Here's how you can replace it yourself:

Locating the Valve

To start, open the dishwasher door and remove the screws securing the outer door panel. Then, pull out the inner sound dampening pad to access the valve.

Removal Process

1. Disconnect the water supply line from the brass elbow fastened to the old valve.
2. Remove the mounting screws securing the valve and the grounding screw.
3. Pull the old valve forward and detach the wire connector.
4. Use pliers to release the clamp securing the outlet hose and pull the hose off.

Installing the New Valve

1. Connect the outlet hose to the new valve and secure it with the clamp.
2. Attach the wire connector to the new valve and position it on the bracket.
3. Secure the valve with the screws and reattach the grounding wire.
4. Wrap Teflon tape clockwise around the threads of the brass elbow and thread it into the new inlet valve.
5. Reconnect the water supply line.

By following these steps, you can successfully replace the water inlet valve in your LG dishwasher. This DIY repair can help resolve common issues and get your dishwasher back to optimal performance. Remember to handle electrical components carefully and ensure all connections are secure before testing the appliance.

Repairing or Replacing the Pump and Motor Assembly

Signs of Pump Failure

Your LG dishwasher's pump and motor assembly might need attention if you notice:

1. Water remaining at the bottom after a cycle
2. Unusual noises during the drain cycle
3. Dishes not getting as clean as before
4. Longer cycle completion times
5. Water leaking from the dishwasher

These signs often point to a faulty drain pump that's struggling to remove dirty water effectively.

Disassembly Steps

To access the pump and motor assembly:

1. Remove the upper and lower racks
2. Take out the wash arm assembly
3. Remove the water guide by loosening it from retaining clips
4. Tilt the machine on its back and remove the bottom access plate
5. Disconnect the overflow, vent, and drain hoses
6. Unplug wire connectors (take a photo for reference)
7. Unscrew the ground wire and sump holders
8. Push in the tabs from underneath to release the assembly

Reassembly and Testing

When installing the new assembly:

1. Ensure the sump gasket is firmly in place
2. Align the arrows on the machine and the new part
3. Press down until you hear the mounting tabs click
4. Secure the sump holders and reattach all wiring
5. Reconnect the hoses and replace the access plate
6. Reinstall the water guide and wash arm
7. Reinsert the dish racks

After reassembly, run a test cycle to check for proper drainage and cleaning performance. If issues persist, you might need to clean out the filter, garbage disposal, or air gap, and ensure the drain hose isn't kinked or blocked.

Maintaining Your PARTSTORE Dishwasher for Longevity

To keep your LG dishwasher running smoothly and extend its lifespan, regular maintenance is key. By following these simple steps, you can ensure optimal performance and avoid costly repairs.

Regular Cleaning Routines

To maintain your LG dishwasher's efficiency, clean it monthly using citric acid or vinegar. This helps remove mineral deposits and keeps the interior fresh. Here's a simple cleaning process:

1. Remove all dishes and racks from the dishwasher.
2. Place a bowl filled with white vinegar (14-17 oz) on the bottom rack.
3. Run a normal cycle with hot water and extra rinse, without detergent.
4. Let the cycle complete fully to eliminate odors and buildup.

Don't forget to clean the filter regularly. Remove it gently, rinse under warm water, and use an old toothbrush to scrub away stubborn grime. The LG ThinQ app can remind you to clean your dishwasher every 30 cycles.

Proper Loading Techniques

Loading your dishwasher correctly not only improves cleaning performance but also prevents damage:

1. Place plates and bowls upright in the bottom rack.
2. Load cups, glasses, and small bowls upside down in the upper rack.
3. Ensure utensils are placed in the designated basket or top rack, avoiding nesting.
4. Position large items like pots and pans at the sides or back of the bottom rack.

Remember to scrape off excess food before loading to prevent clogs. Double-check that utensils aren't protruding, as this can cause leaks or performance issues.

Water Hardness Considerations

Hard water can leave a cloudy film on dishes and the dishwasher's interior. To combat this:

1. Use a rinse aid to improve drying and prevent spots.
2. Consider installing a water softener if you have very hard water.
3. Run hot water in your sink before starting the dishwasher to ensure the right temperature (120°F).

By following these maintenance tips, you'll keep your LG dishwasher running efficiently for years to come.
