The accumulation of moisture in the lower part of the refrigeration unit is not just an aesthetic problem, but a signal that the water drainage system requires your attention. Moisture flowing down the back wall of the chamber should flow freely into the drainage hole, but sometimes this process is disrupted and water begins to accumulate under the drawers or flow out onto the floor. In such cases, the owner of the equipment needs to understand how to clean the tray in the refrigerator in order to prevent the growth of bacteria and the appearance of an unpleasant musty smell.
Many users mistakenly believe that it is enough to simply wipe the puddle with a rag, but the root of the problem often lies in contamination of the tank itself or the drainage system. Condensation tray can be located both inside the chamber (in modern models) and outside, above the compressor (in older units). Ignoring regular cleaning of this element leads to the formation of a slimy coating, which becomes an ideal environment for mold.
In this detailed guide we will look at all the nuances of maintaining the moisture drainage system. You'll learn how to safely remove the tray, the best way to wash it, and how to clean the drainage hole without damaging the internal tubes. Proper care will extend the life of your refrigerator and ensure the hygiene of stored food.
Why water accumulates and when cleaning is needed
The main reason for the appearance of water in the tray is the natural process of moisture condensation, which occurs every time you open the door or place warm food there. In a working refrigerator, this moisture evaporates naturally, but if the humidity balance or temperature conditions are disturbed, the water does not have time to evaporate. If you notice that condensation stays in the tray constantly and does not disappear, this is the first sign of the need for intervention.
Often the problem is aggravated by the fact that food particles, crumbs or pieces of packaging get into the drainage hole. These contaminants mix with water and form a jelly-like mass that clogs the drain. As a result, water overflows over the edge of the inner gutter and ends up at the bottom of the refrigerator or under the vegetable drawers. Timely cleaning allows you to avoid more serious damage, such as metal corrosion or failure of electronics.
It is also worth considering that in some models with the system No Frost water may appear in the pan only during defrosting, which occurs automatically. If a puddle forms regularly, even with the door closed, the seal may be broken or the thermostat settings may be off. In any case, a visual inspection of the pan is the first step towards diagnosis.
⚠️ Attention: If the water in the pan has a pinkish or reddish tint, this may indicate the growth of specific bacteria (for example, Serratia marcescens). In this case, ordinary water cannot be used - disinfection will be required.
Do not wait until the water begins to flow onto the kitchen floor. Regularly checking the condition of the tray will help you avoid damage to the floor covering and the appearance of slippery areas that are dangerous for walking. It is especially important to monitor this summer, when the humidity in the room is high and the condensation process is more active.
Determining the type of construction and location of the tray
Before taking active steps, you need to determine exactly where in your model the moisture collection tank is located. The design of refrigerators from different brands may differ significantly. In most modern models Indesit, Atlant or Beko with a drip defrosting system, the tray is located directly inside the refrigerator compartment, in its lower part, often hidden under a plastic panel or behind drawers.
In older models or refrigerators with manual defrosting, the moisture evaporation tray is located outside, in the lower rear part of the case, directly above motor-compressor. In this case, the water flows out through the tube and evaporates due to the heat of the running engine. Understanding this difference is critically important, since access and cleaning methods will differ radically.
- 🔍 Internal tray: Located under the bottom shelf or behind the decorative trim at the back wall inside the chamber.
- 🔧 External tray: Located at the back of the refrigerator, above the compressor, access to it is possible only by moving the equipment away from the wall.
- 🌪️ No Frost system: Often has a hidden tray at the bottom of the freezer or behind the back panel, access to which requires partial disassembly.
If you cannot find the tray visually, refer to the instruction manual for your models. There is usually a diagram of the device, where all removable elements are indicated. Do not try to forcefully tear off the plastic panels inside the chamber if you are not sure that there is a tray there - plastic at low temperatures becomes brittle and breaks easily.
For models with an external tray, it is also important to evaluate the condition of the drainage tube that goes outside. If it is frozen or clogged, water will drip past the tray directly onto the floor. In such cases, cleaning the pan itself will not solve the problem; cleaning the drainage channel will be required.
Preparation for the procedure: tools and safety
High-quality cleaning of the pan requires preliminary preparation. You can't just grab the first rag you come across and start scrubbing. First, you need to ensure the safety of yourself and the electrical appliance. The most important rule is that before any manipulations related to removing internal elements or accessing the back of the refrigerator, you must disconnect the device from the power supply.
You will need to prepare a certain set of tools and cleaning products. Do not use aggressive chemicals, pure chlorine-containing bleaches or abrasive powders, which can scratch the plastic and create microdamages where dirt will accumulate in the future. The best solution is mild detergents based on soda or vinegar.
☑️ Preparation for cleaning
For work you will need:
- 🧽 A soft sponge or microfiber for wiping surfaces.
- 🚿 A syringe without a needle or a small syringe for washing the drainage.
- 🧴 Dishwashing liquid or food solution soda.
- 🔦 Flashlight for inspecting hard-to-reach places.
Free up space around the refrigerator in advance. If the tray is in the back, you will need to move the heavy unit away from the wall. Do this carefully to avoid damaging the flooring or pinching the copper pipes at the back. Place pieces of thick cardboard or a special lining under the legs of the refrigerator to make moving easier.
If there are products in the refrigerator that require cold, take care of their temporary placement. Remove all removable shelves, drawers and containers to gain maximum access to the bottom of the chamber. This is also an excellent opportunity to wash the chamber itself while it is empty.
Instructions: how to remove and wash the inner tray
Cleaning the inner tray is the most common procedure for modern refrigerators. This element is often made in the form of a plastic bath, which can be removable or stationary. If the tray is removable, carefully remove it by pulling it towards you. If it is secured, cleaning is done in place.
First, remove all accumulated water. Use a sponge or rag to absorb the liquid. Then apply the prepared cleaning solution to the sides and bottom of the tray. Leave the product on for 10-15 minutes so that it dissolves fatty deposits and mucus. After this, thoroughly wipe the surfaces with a soft sponge.
| Type of contamination | Recommended product | Cleaning method |
|---|---|---|
| Grease deposits | Dishwashing detergent solution | Wipe with a sponge, rinse with warm water |
| Mold and mildew | Vinegar solution (1:1) or soda | Apply, wait 15 minutes, rinse thoroughly |
| Unpleasant odor | Activated carbon or citric acid | Wipe and airing |
| Complex contamination | Specialized spray for refrigerators | Follow the instructions on the bottle |
Pay special attention to the drainage hole, which is located in the depths of the tray or immediately behind it. This is where blockages most often form. Take a syringe with warm water and try to gently, without strong pressure, rinse the hole. If the water drains quickly, the drainage is clear. If it is, mechanical cleaning will be required.
What is the danger of clogged drainage?
If you do not clean the drainage hole, water will begin to overflow over the edge of the pan. This will cause moisture to get under the plastic lining of the floor of the refrigerator, which can cause metal corrosion, short circuit wiring and the appearance of a persistent damp smell, which is very difficult to get rid of.
After cleaning, be sure to wipe all surfaces dry. There should be no moisture remaining in the tray before turning on the refrigerator. Install all the elements in their places, making sure that the tray fits evenly and tightly, without distortions.
Maintenance of the external tray and drainage system
If your refrigerator is the type where the tray is located above the compressor at the back, the cleaning procedure will be different. In such models, the water usually evaporates on its own, but over time, dust mixed with water can accumulate in the tray, forming a solid sediment. This reduces the efficiency of evaporation.
To access the outer tray, move the refrigerator away from the wall. Remove the rear protective panel if it is blocking access to the compressor and tray. Be careful not to pull sharply to avoid damaging the tubes. Carefully remove the tray. Often it is simply inserted into grooves or rests on brackets.
Rinse the tray under the tap using a bottle brush to remove old dirt from the corners. If limescale (white deposits) has formed on the bottom, soak the tray in a citric acid solution for half an hour. This will help quickly return it to cleanliness.
- 💨 Blowing: The drainage tube coming out can be carefully blown out or washed with water from a syringe.
- 🌡️ Checking heating: Make sure that the compressor heats up normally, since it is its heat that ensures the evaporation of water from tray.
- 🕸️ Dust removal: While the refrigerator is moved away, vacuum the condenser grille at the back, this will improve cooling.
After washing, put the tray back in place. Make sure the end of the drainage tube is inside the tray and not next to it. Even a slight movement can cause water to drip onto the floor.
⚠️ Attention: When working on the back of the refrigerator, never use sharp objects (knives, wire) to clean the pipes. You can easily puncture the thin drain wall or damage the cooling circuit, which will lead to costly repairs.
After completing the service, return the refrigerator to its place, leaving a gap of a few centimeters from the wall for air circulation. Plug in the appliance and let it run idle for about an hour before loading food.
Mold removal and odor prevention
Mold is the main enemy of cleanliness in the refrigerator. Fungal spores can multiply even at low temperatures, especially in the damp environment of the tray. If you find black or green plaque, it cannot be removed with ordinary water. Disinfection will be required.
Table vinegar is an effective and safe remedy. Mix it with water in a 1:1 ratio and treat the affected areas. Acetic acid kills mold spores and neutralizes odors. After treatment, leave the surface for 15-20 minutes, then rinse thoroughly with clean water.
If the smell is already ingrained in the plastic, use a baking soda solution. Make a paste of soda and water, apply to the walls of the tray and leave until dry. Then rinse off. Baking soda perfectly absorbs odors. You can also use hydrogen peroxide, which is a powerful oxidizing agent and kills bacteria.
After any antibacterial treatment, it is important to ventilate the refrigerator well. Leave the doors open for several hours (or overnight, if the situation with the products allows) so that any remaining cleaning products and odors are completely removed.
Common mistakes when cleaning the tray
Even following the instructions, users often make mistakes that nullify all efforts. One of the most common is to use hot water to defrost ice in a tray or drain. A sudden change in temperature can lead to cracks in the plastic or damage to the tubes.
Another mistake is the use of metal brushes or scrapers. The plastic from which the pallets are made is quite soft. The scratches left behind will become an ideal place for dirt to accumulate, which will no longer be able to be washed out. A smooth surface is the key to cleanliness.
Do not forget about the drainage hole. Many people wash the tray itself, but forget to clean the drainage channel. As a result, after a week, the water stands in the pan again. Drainage permeability is a key factor in the normal operation of the system.
- ❌ Error 1: Use of bleach in high concentrations (can damage the plastic and leave a toxic odor).
- ❌ Error 2: Attempting to clean the drain with a cotton swab (lint may remain inside and worsen the blockage).
- ❌ Error 3: Ignoring checking the installation level of the refrigerator (if it is crooked, water may not get into the drain hole).
It is also a mistake to turn on the refrigerator immediately after washing without drying the elements. Residual moisture can freeze and create an ice plug in the drain during the first cycle of operation.
Can the tray be washed in the dishwasher?
It depends on the type of plastic. If the tray is removable and the instructions do not prohibit it, then it is possible at a temperature no higher than 40-50 degrees. However, high temperatures in the drying mode can deform thin plastic, so it is better to wash it by hand.
What to do if the water in the tray is frozen?
Do not try to break off the ice with a knife. Unplug the refrigerator and let the ice melt naturally. You can speed up the process by placing bottles of warm (not hot) water in the chamber. Using a hairdryer is also possible, but be careful not to overheat the plastic.
How often should you clean the tray?
It is recommended to carry out preventive cleaning every 3-6 months. If you notice the appearance of mucus or odor earlier, the procedure should be carried out immediately. In the summer, the frequency of checks should be increased.
Why is the tray full, even though the refrigerator is new?
In new refrigerators, moisture can be released abundantly from food in the first days of operation. Also check whether you are opening the door too often and whether the refrigerator is located near a heat source. If the problem persists, there may be a factory defect in the drainage system.
What is the best way to wipe the tray for disinfection?
The best choice is a solution of baking soda or table vinegar. They are food safe, effective against bacteria and leave no toxic residue. Specialized chemicals are also acceptable, but require very careful rinsing.
