How to Clean LG Dishwasher: Step-by-Step Guide

Fixing a malfunctioned dishwasher isn’t a tough task, but it can be tricky if you’re doing it for the first time. Either you can fix it by making some minor adjustments, or you need to replace different components if the problem is more complicated.

Here we have demonstrated some of the complications that can restrict the performance of your dishwasher and the ways to resolve them.

Inspect the Water Pump Belt

The water pump belt isn’t in all dishwashers; only some models have it. You should first find out if a water pump belt is already present in your LG dishwasher.

After accessing it, it eliminates its panel present underside.
Usually, a water pump belt lies beneath the motor.
In case of a broken or weary belt, you should look for replacement options.

Assembling Spray Arms

Sometimes the trouble-causing component could be the spray arms of a dishwasher. To make it sure, you must inspect the lower, upper, and center spray arms to start cleaning your LG dishwasher.

Upper Spray Arm

Follow these steps to assemble and clean the upper spray arm:

Drag the upper rack to remove the nozzle present in it.
Drawing the rack forward will help move it from the position.
Now spin the spray arms through the end at both sides.
By lifting the lever in an upward direction, unscrew the spray arms.
Inspect the holes minutely to find any blocking material and clean it quickly.
Put the spray arms back to the upper rack and tight them in place.
Run a test to determine if the spray arms are rotating fine without obstructing.

Lower Spray Arms

Remove the lower rack and spray arms just like you learned in the previous step.

Examine the holes to see any cloggings.
You can simply remove the lower spray arm by dragging it with your hands.
Clean the spray arms and their holes
Place it back to the position with less force push.
Do not push or pull it hard as it might damage the nozzle and your hand if it scratches with any sharp part.

Top Spray Arms

First, check the water jet holes and clean them to remove a hard object stuck inside them.
You can use a screwdriver to pick the retainer clip out of the bracket holding spray arms.
When you remove the spray arm, clean it and fix it by using retainer clips.

Important Instructions: Our team of experts recommends cleaning spray arms at least once every two weeks.

Unblocking Valve to Enter Water

Valves play a great role in allowing water entrance inside the dishwasher. If something blocks the valve or it is broken, the dishwasher will not be able to clean dishes.

In case of heavy damage to the valve, replacement is the right option. However, try to clean it in simple ways if the issue is just ordinary.

Examine the Circulation Pump

The water is propelled through the spray arms when the motor of the circulation pump induces force. In case of a faulty circulation pump, you won’t be able to clean anything.

You can evaluate the issue by noticing the sound produced by the motor. If no loud is coming out of motor and you can only hear a humming sound, it means the motor of your dishwasher has burned.

To solve it, make sure the motor is getting a power supply.
Look for the debris inside the pump that aids in turning the impeller.
If there is no debris inside the pump and the power is also reaching towards the motor but still not working, then replace it immediately.

Important Instructions: Replacing the circulation pump can be tricky; that is why it is better to decide with care if you will do it or hire some professional.

Replace Defective Wash Impeller

The purpose of the wash impeller is to push water out of the spray arms. It is a small tube made of a plastic blade. The broken or defective impeller won’t be able to give out sufficient power for forcing water.

The best solution to this is to replace the defective wash impeller with a new one. If the damage is severe, you may also need to replace the whole motor and the pump.

How to Clean LG Dishwasher With Vinegar

Cleaning the LG dishwasher with vinegar is a good option, but sometimes it is better to avoid using it. It depends on your model to decide if the vinegar should be used in it or not. You can clean the LG dishwasher using vinegar as follows:

Remove all the parts of the dishwasher, including dishes and racks.
Pick a bowl and add vinegar to it to be placed on the upper rack.
Turn on the cycle of your dishwasher that complies with the quick heat setting.
After cleaning, let the dishwasher’s door open for a while to dry the interior.

Once you are done cleaning your LG dishwasher, you can do all the kitchen tasks efficiently.

How to Clean LG Dishwasher With Baking Soda

You can also use baking soda to clean your LG dishwasher. It is mild as compared to vinegar and excellent for eliminating stubborn stains. The bad smells can also be removed by just sprinkling baking soda.

Add a cup of baking soda to your dishwasher and turn on the rinse cycle.

If you haven’t gotten rid of it, add some extra quantity of baking soda to it.
After running the cycle, allow your dishwasher to dry for some time.
