LG Dishwasher Parts & Their Functions

Lower spray arm

The lower spray arm is a rotating arm that sprays water on the dishes in the bottom rack of the dishwasher. It attaches to the lower rack assembly, and it rotates to spray water on these items.

The lower sprayer has a sensor that detects when it needs cleaning or adjustment, so you don’t have to worry about forgetting about this part when cleaning your house or apartment!

Upper spray arm

The upper spray arm is a part of the dishwasher’s upper wash pump and comes in two parts. It helps to remove food particles from dishes, but it also connects to the lower spray arm, which helps distribute water evenly over your dishes. This means that when you use an LG dishwasher, you can get better results because your dishes will be cleaned more thoroughly with less wasted water.

The removable cap on this piece allows easy cleaning when you want to clean away any dried-on food residue or grime that might have accumulated since the last time you ran your dishwasher.

Filter/filter holder

The filter is made of a fine mesh and sits on the top of your dishwasher. It’s located on the right side, which means it’s positioned under where you’ll usually put your dishes as they’re being cleaned.

You may also be wondering what this filter does. Well, it helps keep nasty odors from coming into your home.

Dispenser drawer

The dispenser drawer is located on the left side of your dishwasher, and it’s used to dispense detergent. You can replace this part if it gets damaged or worn over time.

Upper rack assembly

The upper rack is a tray that holds dishes. It has a cut-out for tall items so that you can put your tall glasses and mugs there. This makes it easy to grab everything at once if you’re doing the dishes in no time. The upper rack can be removed from its housing and cleaned separately, making this part of your dishwasher easy to clean, even when full of dirty dishes!

You can adjust how high or low this shelf goes by turning it up or down with its handle—and it doesn’t matter which way you set it; they’re both equally sturdy!

Silverware basket

The silverware basket is a part of the LG dishwasher and is on the lower rack. It’s used to hold your silverware so that you don’t have to worry about dropping it into the water while you’re loading up your dishes.

Detergent dispenser

The detergent dispenser is a part of the dishwasher, and it’s used to dispense detergent into your machine. It’s located on the door, so you’ll know where it is when you open your dishwasher to add soap or other items.

The best way to use this part of your LG dishwasher is by opening its door and adding some detergent into its chambers before closing them again. If spills are inside your machine due to improper usage (like spilling liquid), then you should wipe off any excess with paper towels before closing off both sides again!

Tub assembly

The tub assembly is the most visible part of your dishwasher and takes up most of its space. It contains two parts:

A pump and motor are attached to the bottom of the tub. This pump moves water through hoses into detergent dispensers, spraying onto dishes as they are being washed.

A drain hose is connected to a hole at the bottom of your dishwasher so that any leftover dirty water can be drained out when you’re done using it.

Float switch (pressure switch)

The float switch is a small device that senses the water level in the tub and sends a signal to the control panel, which then shuts off the water supply. This prevents overfilling of your dishwasher and helps prevent flooding, which can damage your dishwasher.

The float switch is typically located on top or bottom of your LG dishwasher, but you might have to remove it if you don’t see it readily available in its place.

The tub of the dishwasher

The dishwasher tub is the part of your LG dishwasher that holds dirty dishes and cleans them. It’s made of stainless steel, plastic, or other materials—and it may have a design you like or not.

Door lock

The door lock is part of the control panel. It’s used to lock or unlock the dishwasher so you can access it easily, and it also lets you know when your appliance is running. If this part gets broken, then your dishwasher will not work properly.

Control Panel

The control panel has several buttons on it:

Power button – This turns the power on or off for your dishwasher. Always use this button before operating other machine parts as an extra safety measure!

Control Panel Buttons – These buttons allow you to select options within each program type (basically, how much water/soap is used). For example, if we were using a “Heavy Wash” program with lots of soap in our dishes, then pressing one would cause more detergent to be dispensed into each load than if we pressed another option; this way, we can choose between different amounts without having to change settings manually every time we want something different done with our machine!

Water Fill Inlet

The water inlet valve assembly is the part of your dishwasher that connects to the faucet. It’s usually located on the bottom front section of your LG dishwasher and can be easily accessed by removing two screws on either side.

The water fill inlet is a small opening in this assembly, which allows water from your sink or another source to enter your LG dishwasher when you open its door after placing dishes inside.

The upper spray arm assembly holds one end of each spray arm and has an upper turret with four holes for mounting various parts (such as knobs) onto it; these holes are visible through an access hole in its base plate at one end—you may have seen this piece referred to as “the upper arm.”

Rinse Aid Cap

The rinse aid cap is located on the inside of the door. It’s used to add rinse aid, which helps your dishes to dry more quickly. You can also use it as a container for salt or vinegar if you’d like a more seasoned dishwasher cycle.

Dryer Fan

The dryer fan is located on the lower right side of your dishwasher. It helps to dry dishes, preventing water spots and keeping a more even drying pattern. This is not used during normal dishwasher operation, but it can be turned on when you select “dry” cycles or use other special features like sanitizing or cleaning glassware.

Upper Spray Arm Assembly

The upper spray arm assembly is located in the upper rack and allows water to spray over the dishes in this area. This part of your dishwasher is made of plastic, so it’s easy to clean. You can remove it for cleaning or replace it if it gets damaged during normal use.

Lower Spray Arm Assembly

The lower spray arm assembly is a part of the dishwasher and helps to clean dishes. It is located in the bottom of your LG dishwasher and can be removed by turning it clockwise, then removing it from its mounting bracket.


The base is the part of your dishwasher that sits on the floor. It can be made from plastic or metal, and it’s usually flat (i.e., not slanted). The base supports all of the other parts of your dishwasher, so it’s important to choose one that fits well with its surroundings.

The base can also support the door, which is why it’s important to choose one that fits well with its surroundings.
