The appearance of a puddle of water under the refrigerator or an unpleasant odor inside the chamber often indicates that the moisture removal system has failed. In refrigerators Bosch, as in other models with a NoFrost or drip-type system, a special container located at the bottom of the unit is responsible for collecting excess liquid. If this element is dirty, displaced or damaged, moisture stops evaporating normally and begins to leak out.
Owners of German equipment are often faced with the need for preventive cleaning or replacement of this unit. It is important to understand that evaporation tray is located in a hard-to-reach place, usually hidden by the back panel or compressor. Careless actions when trying to get to it can lead to damage to the tubes or loss of system tightness. Therefore, before starting work, you need to clearly understand the design of your model.
In this article we will analyze in detail the algorithm for safely dismantling the condensate container. You will learn what tools you will need, how to properly prepare equipment for servicing, and what to pay special attention to during assembly. Compliance with the technology will avoid costly repairs and extend the life of your refrigeration equipment refrigeration equipment.
The principle of operation of the moisture removal system
To understand why it is important to keep the tray clean, you need to understand the physics of the process. During operation, the compressor heats up, and the evaporator, on the contrary, cools. During defrosting or in the drip system mode, water flows down the gutter into the drainage hole. From there it enters a special bath installed directly above the motor-compressor.
The heat from a running engine promotes rapid operation moisture evaporation, so under ideal conditions water should not accumulate anywhere. However, over time, dust may settle in the tray, mixing with water, it turns into mucus. This substance can clog channels or simply prevent normal evaporation, causing overflow.
In models Bosch the design is often made in such a way that the tray has a complex geometry to increase the evaporation area. If you notice that the water does not drain, the angle of inclination may be incorrect or the tray itself may be deformed. Regular inspection of this unit helps prevent the formation of mold and bacterial growth.
Required tools and preparation
Before you begin dismantling, it is necessary to ensure safe working conditions. A refrigerator is an electrical appliance that uses refrigerants, so there is no rush here. You will need a minimum set of tools, which can be found in every home.
First of all, provide access to the rear wall of the unit. Move the refrigerator away from the wall at a distance of at least 50-70 centimeters. This will allow you to move around the device freely and see all the fasteners. Make sure the floor is dry to prevent slipping.
To perform the work you will need:
- 🔧 Phillips screwdriver (usually PH2 size) for removing protective panels.
- 🧤 Rubber gloves to protect your hands from dirt and possible mold.
- 🧼 A container with warm water and detergent for washing the part.
- 🔦 A flashlight for inspecting hard-to-reach places behind the compressor.
A critical step is turning off the power. Unplug the cord from the outlet. It is not enough to simply turn off the refrigerator with a button; you must completely turn off the power supply. It is also worth waiting about 30-60 minutes for the compressor to cool down, if it has been running up to this point.
☑️ Preparation for maintenance
Access to the bottom of the refrigerator
The design of refrigerators Bosch may vary depending on the series. In some models, the condensate tray is visible immediately after removing the lower rear cover, in others it is hidden under the compressor casing. Most often, access is through the rear panel.
Remove the bottom protective cover. It is usually attached to several screws or plastic latches. If you use screws, carefully remove them and place them in a magnetic tray or jar to avoid losing them. Be careful not to strip the threads.
After removing the panel, you will have a view of the compressor (the black metal “tank”). The required container will be located above it or next to it. In some models evaporation tank is attached to a bracket, which may also require dismantling.
⚠️ Attention: Never try to forcefully bend the metal elements of the frame. Thin-walled tubes of the refrigeration circuit are very easy to damage, which will lead to freon leakage and expensive repairs.Algorithm for removing the condensate container
The process of removing the tray requires care. Depending on the specific model Bosch, fixation may differ. Most often, the container is simply inserted into the grooves or pressed against the guides.
If the tray is completely removable:
- 👐 Take the container with both hands on opposite sides.
- ↕️ Smoothly pull it towards you and slightly up to disengage it from the latches.
- 💧 Be prepared for the fact that there may be water inside, so keep the container horizontal.
In cases where the tray is secured with screws, they must first be unscrewed. Sometimes access to the fastener is difficult, and you have to work by touch or use a screwdriver extension. If the tray is divided into sections, remove them sequentially, starting from the outer one.
Pay attention to the drainage tube. It can be inserted into the hole in the tray or run alongside it. When removing the container, it is important not to pull the tube sharply, so as not to break its connection with the refrigerator body. If the tube is in the way, carefully move it to the side.
What to do if the tray cannot be removed?
If the container does not budge, do not use force. It may have frozen or jammed due to dirt. Try slightly warming the plastic case with a hairdryer (without overheating!) or dripping warm water into the joints to soak away dirt.
Cleaning, disinfection and integrity check
After removing the part, the maintenance stage begins. Even if the tray appears clean visually, there may be colonies of bacteria on its bottom and walls that cause an unpleasant odor. Rinse the container thoroughly with warm water and a neutral detergent.
For disinfection, you can use a weak solution of vinegar or special products for household appliances. It is not recommended to use aggressive chemicals or abrasive powders, as they can damage the plastic and make it brittle. After washing, be sure to rinse the part with clean water.
While the tray is drying, inspect the installation niche itself and the drainage hole. Often the blockage is located in the channel where the water flows. You can clean it with a brush or soft wire. Make sure that the tube has no cracks or creases.
The table below will help determine the condition of the part and the necessary actions:
Part condition Symptoms Recommended action Normal Clean plastic, no cracks Rinse and install back Contamination Deposit, mucus, smell Soak in a disinfectant solution Mechanical damage Cracks, chips, holes Replace with a new original part Deformation Change in geometry due to heating Replace because water flow is impaired If you find cracks, trying to seal the tray is a temporary solution. Constant contact with water and temperature changes will quickly destroy any glue. It is better to order an original spare part Bosch by catalog number.
Assembly and final check
Installation is carried out in the reverse order. Make sure the tray and seat are completely dry. Insert the container into the guides until you hear a characteristic click or a tight fit. Check that the drainage tube is inside the tray (if the design allows for the end of the tube to be immersed in water for a water seal).
Secure the protective panel. All screws must be tightened tightly, but not fanatically, so as not to damage the plastic. After assembly, return the refrigerator to its place, maintaining the necessary clearances for ventilation.
Plug in the appliance. During the first hours of work, listen to sounds. It is normal if you hear a quiet gurgling or hissing sound - this is refrigerant circulating through the system and water dripping into the tray. If the water continues you
