1.2. Soft Brush or Toothbrush

Obtain a soft brush or toothbrush that will allow you to scrub the inner surfaces of the water dispenser gently. Ensure that the brush has soft bristles to avoid damaging the dispenser.


1.3. Microfiber Cloth or Sponge

Grab a microfiber cloth or sponge that can be used in conjunction with the cleaning solution to wipe down the dispenser’s surfaces.


1.4. Warm Water

Have a bowl or container filled with warm water nearby for rinsing the dispenser after cleaning.


Disconnect the Water Supply and Empty the Dispenser

2.1. Unplug the Refrigerator

Before starting the cleaning process, unplug your refrigerator from the power source to ensure safety and prevent any accidental dispensing of water.


2.2. Disconnect the Water Supply

Check the back of your refrigerator to locate the water supply line. Turn off the water supply valve and carefully disconnect the water line from the dispenser. This step ensures that no water flows into the dispenser during the cleaning process.


2.3. Empty the Dispenser

Dispense any remaining water from the dispenser into a sink or container. Holding down the dispenser lever for a few seconds will drain out any residual water.


Remove Removable Parts

3.1. Check for Removable Parts

Inspect the water dispenser for any removable parts, such as drip trays, grilles, or water reservoirs. These parts are usually designed to be easily detached for cleaning purposes.


3.2. Remove and Soak in Cleaning Solution

Gently remove any detachable parts from the dispenser and soak them in the prepared cleaning solution. Allow them to soak for several minutes to loosen any mold or mildew buildup.


Clean the Dispenser Interior

4.1. Dampen the Microfiber Cloth or Sponge

Dampen the microfiber cloth or sponge in the cleaning solution. Ensure that it is well saturated but not dripping.


4.2. Wipe the Inner Surfaces

Carefully wipe the inner surfaces of the water dispenser. Pay special attention to the areas where mold and mildew are likely to accumulate, such as the nozzle, spout, and the areas around the dispenser lever.


4.3. Use the Soft Brush or Toothbrush

If the water dispenser is not cleaned for a long period of time, stubborn mold or mildew spots may develop. For stubborn mold or mildew spots, use a soft brush or toothbrush to gently scrub the affected areas. Apply light pressure and small circular motions to dislodge any embedded mold.


4.4. Repeat the Cleaning Process

If necessary, dip the brush into the cleaning solution or sprinkle baking soda onto the bristles for additional cleaning power. Continue gently scrubbing until the mold has been completely removed.


Clean the Removable Parts

5.1. Scrub the Soaked Parts

While the removable parts are soaking in the cleaning solution, scrub them with a soft brush or toothbrush to remove any mold or mildew. Pay attention to crevices or grooves where mold can hide.


5.2. Rinse the Parts

Thoroughly rinse the soaked parts with warm water to remove any remaining cleaning solution and loosened mold. Ensure that there are no residual cleaning products left on the parts.


5.3. Dry the Parts Completely

After rinsing, dry the removable parts completely before reattaching them to the water dispenser. Use a clean towel or allow them to air dry.


Rinse and Wipe Down the Dispenser

6.1. Rinse the Dispenser

Fill a bowl or container with warm water and use it to rinse the dispenser’s interior. Use a clean microfiber cloth or sponge soaked in warm water to wipe away any remaining cleaning residue. Make sure to rinse thoroughly to remove all traces of the cleaning solution.


6.2. Dry the Dispenser

After rinsing, use a clean, dry microfiber cloth to wipe down the dispenser’s surfaces. Ensure that all areas are completely dry, as moisture can contribute to mold growth.


Reattach and Reconnect

7.1. Reattach the Removable Parts

Once the dispenser is completely dry, reattach the removable parts, such as drip trays, grilles, or water reservoirs. Ensure that they are securely and properly placed.


7.2. Reconnect the Water Supply

Carefully reconnect the water supply line to the dispenser, ensuring it is tightly connected to prevent any leaks. Turn on the water supply valve, and check for any leaks or water drips.
