How To Clean an LG Dishwasher

October 11, 2023

Ever had that moment when you open your LG dishwasher, ready to unload gleaming dishes, only to find them speckled with food particles or streaked with soap residue? So what went wrong?

The answer is – dishwashers need regular TLC, just like anything else in our homes that works hard for us (think HVACs and washing machines). That’s right, they need to be cleaned regularly too. If anything, that’s key to maintaining their performance.

Importance of Maintaining Your LG Dishwasher

Left unattended, tiny bits of food particles can become lodged in hard-to-see places such as the spray arms and that can lead to clogs. And if that happens, water won’t be able to flow properly, meaning that your dishwasher won’t be able to do a good job of cleaning your dishes.

That’s why it’s so important to keep up with periodic maintenance – that way, it’ll be able to stay at peak performance.

Not only that but it’ll extend the life of the machine as well. The reason? Build-up from mineral deposits and lingering food debris can reduce cleaning efficiency over time.

How Regular Cleaning Helps Your Dishwasher

Routine care will help ensure that water flows freely through the spray arms while reducing residual build-up inside.

It’s also important to clean and maintain the filter as that will help catch the sneaky bits that try to get onto your sparkling plates (refer to the owner’s manual on how to locate the filter).

Consequences of Having a Dirty LG Dishwasher

Mineral Buildup

A major culprit is mineral buildup. Hard water can leave white spots on your dishes and cloud their appearance over time. But what you may not realize is these minerals don’t just affect how clean your plates look; they also compromise the efficiency of your LG dishwasher.

Reduction in Cleaning Performance

The buildup will also reduce the machine’s cleaning performance over time. To give you a better idea, studies have shown that mineral and food particle accumulation can reduce wash effectiveness by up to 20%.

That means one out of every five dishwashing cycles could essentially be a wasted effort. Now there’s an unsettling thought…

How to Properly Clean the Spray Arms

Remove the screws to detach the upper spray arm. From there, remove the clip and lift away the bottom spray arm. Rinse them both thoroughly with water.

If necessary, you can use a toothpick or tweezers to remove build-up from the opening. You can also soak the spray arms in white vinegar for about 20 to 30 minutes – that will dissolve any build-up and remove odors.

How to Clean an LG Dishwasher Filter

To clean the filter, you want to first turn off your appliance’s power supply. From there, locate the mesh filter within your washer compartment (it’s usually at the base of the spray arms or in a corner).

You’ll need warm soapy water and a soft brush – use them to clean away any residual soils thoroughly before rinsing these components under running tap water until no soap remains on their surface.

Note: Make sure to lock the filter in place after cleaning (turn the filter clockwise until it’s secure).
